DESCRIPTION OF THE INVENTION

[0018] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The same configurations are designated by the same reference numerals in the drawings. The sizes, dimensions, positional relationships, and the like of the illustrated configurations shown in the drawings are merely examples and are not limited to those illustrated in the drawings.

[0019] FIG. 1A and FIG. 1B show a cut resistant glove 10a (hereinafter also referred to as glove 10a) according to one embodiment. The glove 10a includes a glove body 20 that is composed of at least one pile knitted fabric 25. The at least one pile knitted fabric 25 can be one pile knitted fabric 25 or can be a plurality of pile knitted fabrics including the pile knitted fabric 25 as each pile knitted fabric.

[0020] The glove body 20 is knitted into a glove shape using at least one pile knitted fabric 25, and is a textile product arranged to cover the wearer's hand when the glove 10a is worn. The glove body 20 includes a bag-shaped body bag 21 that is arranged to cover the back and palm of the wearer's hand when the glove 10a is worn. The body bag 21 includes a back part 21a (FIG. 1A) arranged to cover the back of the wearer's hand, and a palm part 21b (FIG. 1B) arranged to cover the palm of the wearer's hand. In addition to the body bag 21, the glove 10a can include a finger bag part 22 extending from one end side of the body bag 21 and arranged to cover the wearer's fingers, and a sleeve part 23 extending from the other end side of the body bag 21 and arranged to cover the wearer's wrist. The finger bag part 22 can include a first finger bag 22a arranged to cover the wearer's thumb, a second finger bag 22b arranged to cover the index finger, a third finger bag 22c arranged to cover the middle finger, a fourth finger bag 22d arranged to cover the ring finger, and a fifth finger bag 22e arranged to cover the little finger. These parts (21 to 23) of the glove body 20 can be knitted without seams, for example. In other words, the glove body 20 can be knitted into a glove shape using one pile knitted fabric 25. Alternatively, these parts (21 to 23) of the glove body 20 can be sewn together to form the glove body 20 as a whole. In other words, the glove body 20 can be formed into a glove shape by sewing together the pile knitted fabric for the body bag 21 and other pile knitted fabrics for the other parts (22, 23).

[0021] The shape of the glove body 20 can be any shape that allows a person to wear the glove body 20 on his or her hand to perform some kind of manual work, and is not limited to the glove shape shown in FIG. 1A and FIG. 1B. As an example of another shape, the glove body can have a mitten shape. When the glove body has a mitten shape, it can have a modified and integrated shape compared to the glove-shaped glove body 20 shown in FIG. 1A and FIG. 1B, for example, such that the second finger bag 22b to the fifth finger bag 22e are formed into one bag shape, or such that the third finger bag 22c to the fifth finger bag 22e are formed into one bag shape.

[0022] The pile knitted fabric 25 is a knitted fabric including a plurality of yarns that contain a ground yarn and a pile yarn, and are pile-knitted. The pile knitted fabric 25 is a type of plain knitted structure, and has a knitted structure in which a plurality of loops protrude on the surface of the knitted fabric, and each loop is in the shape of a ring. The ground yarn is a yarn that forms the basis of the pile knitted fabric 25 and that is composed of, as a constituent unit, a cut resistant yarn or a combination of two or more yarns containing a cut resistant yarn. When knitting the pile knitted fabric 25, for example, one cut resistant yarn can be used as the ground yarn as is, or a group composed of a plurality of yarns containing at least one cut resistant yarn can be used as the ground yarn. The pile yarn is a yarn as a constituent unit that forms the pile knitted fabric 25 together with the ground yarn so as to be pulled out longer than the ground yarn from the back stitch 25b (FIG. 1A) of the pile knitted fabric 25 to form a plurality of loops, or is a combination of two or more yarns containing this yarn as a constituent unit, as shown in FIG. 2A and FIG. 2B. For example, one yarn having flexibility capable of forming the plurality of loops can be used as the pile yarn as is, or a group composed of a plurality of yarns each having such flexibility can be used as the pile yarn.

[0023] The back stitch 25b of the pile knitted fabric 25 is composed of a heat insulation layer 252 that is arranged on the inside of the glove body 20 (the side that comes into contact with the wearer's hand when the glove 10a is worn), and that is formed by a plurality of loops of the pile yarn pulled out longer than the ground yarn. That is, the heat insulation layer 252 is a layer of the pile knitted fabric 25 that is formed of a plurality of loops of the pile yarn and does not contain the ground yarn. The heat insulation layer 252 can be formed continuously, for example, on at least a part of the inner surface of the glove body 20 (the side that comes into contact with the wearer's hand when the glove 10a is worn), but it is preferable that the heat insulation layer 252 be formed over the entire inner surface of the glove body 20. The face stitch 25a of the pile knitted fabric 25 is arranged on the outside of the glove body 20 (the side that does not come into contact with the wearer's hand when the glove 10a is worn), and is a part formed by a fabric structure layer 251 in which the ground yarn and the pile yarn are entangled. That is, the fabric structure layer 251 is a layer of a basic part of the pile knitted fabric 25 that contains the ground yarn and the pile yarn. The fabric structure layer 251 can be formed continuously on at least a part of the outer surface of the glove body 20 (the side that does not come into contact with the wearer's hand when the glove 10a is worn), but it is preferable that the fabric structure layer 251 be formed over the entire outer surface of the glove body 20.

[0024] The ground yarn is a yarn that has cut resistance properties by containing at least one cut resistant yarn. The at least one cut resistant yarn can be, for example, one cut resistant yarn, and from the viewpoint of further enhancing the cut resistance properties, it is preferable that the at least one cut resistant yarn be two or more cut resistant yarns. In other words, the ground yarn can be, for example, a yarn containing one cut resistant yarn, but it is preferable that the ground yarn be composed of two or more cut resistant yarns containing this one cut resistant yarn. The cut resistant yarn contained in the ground yarn can be, for example, a spun yarn containing a plurality of inorganic short fibers. Alternatively, examples of the cut resistant yarn contained in the ground yarn which can be preferably used include a monofilament yarn containing a filament of one type or a multi-filament yarn containing a plurality of filaments of at least one type selected from the group consisting of: a filament made of a fiber-reinforced resin containing an inorganic short fiber of at least one type selected from a short metal fiber, a short glass fiber, and a short carbon fiber; a filament made of a synthetic resin in which inorganic particles are dispersed; a metal filament; a glass filament; and a carbon filament. The metal filament can be a metal wire in other words. It is further preferable to use, as the cut resistant yarn contained in the ground yarn, a monofilament yarn containing a filament of one type or a multi-filament yarn containing a plurality of filaments of at least one type selected from the group consisting of: a filament made of the fiber-reinforced resin; and a filament made of a synthetic resin in which inorganic particles are dispersed.

[0025] From the viewpoint of further enhancing the cut resistance properties, the fineness of the at least one cut resistant yarn can be, for example, 30 dtex or more, 50 dtex or more, or 80 dtex or more. The fineness of the at least one cut resistant yarn can be, for example, 400 dtex or less, 250 dtex or less, or 200 dtex or less, from the viewpoint of preventing the touch feel of the pile knitted fabric 25 from becoming too hard. It is to be noted that when the object for which the numerical value of the fineness is indicated is composed of two or more yarns, the fineness herein means the total fineness of the two or more yarns. For example, when the at least one cut resistant yarn is a plurality of cut resistant yarns, the value of the fineness of the at least one cut resistant yarn is the sum of the finenesses of the cut resistant yarns contained in the plurality of cut resistant yarns. In addition, the fineness value is herein a value calculated by winding up 100 m of a sample yarn using a known measuring machine, then measuring its mass, and then multiplying the measured mass by 100 to obtain the mass (i.e., fineness (dtex)) per 10,000 m. When expressing the thickness of the spun yarn, the unit of dtex is herein used to indicate the fineness value of the spun yarn, rather than the cotton count or metric count.

[0026] Examples of the metal fiber include a filament such as a stainless steel fiber or a tungsten fiber. From the viewpoint of further improving the cut resistance properties, the fiber diameter of one metal fiber can be, for example, 10 m or more, or 20 m or more, and from the viewpoint of preventing the pile knitted fabric 25 from becoming too hard, it can be, for example, 50 m or less, or 40 m or less. From the viewpoint of preventing the touch feel of the pile knitted fabric 25 from becoming too hard, the ground yarn can be, as a cut resistant yarn, a yarn containing one metal fiber or two to three metal fibers, for example, but it is preferable for the ground yarn to be a yarn containing one metal fiber or two metal fibers.

[0027] A glass fiber is a filament that can be formed, for example, by extruding fused silica-based glass or another formulated glass into a thin strand or filament. Glass fibers are available from fiberglass manufacturers such as, for example, B&W Fiber Glass Inc. From the viewpoint of further enhancing the cut resistance properties, the glass fiber is preferably a filament made of glass having a Mohs hardness of 3.0 or more. The at least one cut resistant yarn can be, for example, one multi-filament yarn composed of a bundle of glass fibers, or preferably a combination of two multi-filament yarns, each multi-filament yarn being composed of a bundle of glass fibers. The single yarn fineness of the multi-filament yarn composed of a bundle of the plurality of glass fibers can be, for example, 50 dtex or more, or 80 dtex or more from the viewpoint of further enhancing the cut resistance properties, and can be, for example, 250 dtex or less, or 150 dtex or less from the viewpoint of preventing the pile knitted fabric 25 from becoming too hard. The term single yarn herein refers to one fiber out of the plurality of fibers that compose a multi-filament yarn in a multi-filament yarn, and in the case of the spun yarn, herein refers to a yarn formed as one yarn by spinning.

[0028] A synthetic fiber containing an inorganic short fiber and a synthetic fiber containing inorganic particles are filaments that can be produced by kneading inorganic short fibers or inorganic particles into synthetic fibers while adjusting the amount of inorganic short fibers or inorganic particles added to a melt-kneaded resin depending on the desired level of the cut resistance properties when the synthetic fibers are spun by melt-kneading and extrusion molding the resin. Examples of the inorganic short fiber include a short fiber of at least one type selected from a metal fiber, a glass fiber, and a carbon fiber, among of which, the glass fiber is preferable. The inorganic short fiber can be, for example, a fiber that is once produced as an inorganic filament and then shortened. As inorganic particles, for example, particles of silicon carbide, silicon nitride, boron carbide, or boron nitride can be used.

[0029] From the viewpoint of further enhancing the cut resistance properties, the ground yarn is preferably a composite yarn containing at least one cut resistant yarn and at least one reinforcing yarn. As a method of combining the at least one cut resistant yarn and the at least one reinforcing yarn in this composite yarn, covering or twisting of these yarns, or a combination thereof can be adopted. The at least one reinforcing yarn can be one reinforcing yarn, or can be two or more reinforcing yarns. From the viewpoint of achieving even better cut resistance properties and preventing a hard and scratchy feel caused by the cut resistant yarn from becoming apparent, it is preferable that the ground yarn be, for example, a covering yarn having at least one cut resistant yarn as a core yarn and at least one reinforcing yarn as a sheath yarn. From a similar viewpoint, it is further preferable that the ground yarn be, for example, a double covering yarn in which at least one cut resistant yarn is served as a core yarn, one reinforcing yarn is served as a first sheath yarn, and another reinforcing yarn is served as a second sheath yarn, and the second sheath yarn is wound around the outer periphery of the covering yarn in which the first sheath yarn is wound around the core yarn. From a similar viewpoint, the ground yarn is preferably a yarn obtained by combining, for example, any of the composite yarns exemplified herein with another composite yarn.

[0030] Although the reinforcing yarn does not fall under the category of the cut resistant yarn described above (a monofilament yarn containing a filament of one type or a multi-filament yarn containing a plurality of filaments of at least one type selected from the group consisting of: a filament made of a fiber-reinforced resin containing an inorganic short fiber of at least one type selected from a short metal fiber, a short glass fiber, and a short carbon fiber; a filament made of a synthetic resin in which inorganic particles are dispersed; a metal filament; a glass filament; and a carbon filament), the reinforcing yarn is a yarn that can improve the cut resistance properties of the ground yarn when used as the ground yarn in combination with the cut resistant yarn described above. The reinforcing yarn can be, for example, a yarn containing a fiber of one type selected from the group consisting of a para-aramid fiber (polyparaphenylene terephthalamide fiber), a meta-aramid fiber, and an ultra-high molecular weight polyethylene fiber. Examples of the para-aramid fiber include a commercially available fiber under a trademark such as Kevlar, Technora, Twaron, or Heracron. Examples of the meta-aramid fiber include a commercially available fiber under a trademark such as Nomex, or Teijinconex. Examples of the ultra-high molecular weight polyethylene fiber include a commercially available fiber under a trademark such as Dyneema, or Spectra.

[0031] The reinforcing yarn described above can be a spun yarn containing a plurality of short fibers, a blended yarn in which short fibers of two or more types are blended, a filament yarn composed of filaments, a blended yarn composed of filament yarns of two or more types, or a yarn containing a short fiber and a filament. From the viewpoint of further enhancing the cut resistance properties, the fineness of the at least one reinforcing yarn can be, for example, 100 dtex or more, 250 dtex or more, or 400 dtex or more, and is preferably 500 dtex or more. From the viewpoint of preventing the pile knitted fabric 25 from becoming too hard, the fineness of the at least one reinforcing yarn can be, for example, 1,500 dtex or less, or 1,300 dtex or less, and is preferably 900 dtex or less, more preferably 750 dtex or less.

[0032] As the ground yarn, a ground yarn which consists solely of at least one cut resistant yarn can be used. For example, as the ground yarn, a ground yarn which consists solely of one cut resistant yarn, or a ground yarn which consists solely of two or more cut resistant yarns can be used. When using a ground yarn consisting solely of two or more cut resistant yarns, the ground yarn can be, for example, a double yarn formed by twisting two cut resistant yarns together, a triple yarn formed by twisting three cut resistant yarns together, or a drawn-aligned yarn formed by drawing and aligning together two or more cut resistant yarns in an untwisted state. Alternatively, as the ground yarn, a ground yarn which consists solely of, for example, at least one composite yarn can be used. The at least one composite yarn can be one composite yarn or can be two or more composite yarns. One composite yarn (each composite yarn contained in two or more composite yarns) can be a combination of one cut resistant yarn or two or more cut resistant yarns and one reinforcing yarn or two or more reinforcing yarns produced, for example, by twisting them together, covering them once or covering them twice or more times, or drawing and aligning them together in an untwisted state. When using, as a ground yarn, a yarn consisting solely of two or more composite yarns, the ground yarn can be, for example, a double yarn formed by twisting two composite yarns together, a triple yarn formed by twisting three composite yarns together, or a drawn-aligned yarn formed by drawing and aligning together two or more composite yarns in an untwisted state. Alternatively, as the ground yarn, a ground yarn which contains at least one cut resistant yarn and at least one composite yarn can be used. As the ground yarn, a ground yarn which is composed of, for example, a combination of one cut resistant yarn or two or more cut resistant yarns and one composite yarn or two or more composite yarns produced by twisting or covering them together can be used.

[0033] The ground yarn can, for example, be composite yarn containing at least one cut resistant yarn and at least one auxiliary yarn. Alternatively, the ground yarn can, for example, be composite yarn containing at least one cut resistant yarn, at least one reinforcing yarn, and at least one auxiliary yarn. The at least one auxiliary yarn can be one auxiliary yarn, or can be two or more auxiliary yarns. As the auxiliary yarn, a known flexible spun yarn or multi-filament yarn can be used, for example, a spun yarn or filament yarn containing a plant fiber, an animal fiber, a regenerated fiber, or a relatively soft synthetic fiber can be used, and preferably a spun yarn or filament yarn containing a plurality of polyester fibers can be used. From the viewpoint of imparting water absorption and quick-drying properties to the ground yarn, it is preferable to use, as at least one auxiliary yarn, a drawn-aligned yarn formed by drawing and aligning together two or more high multi-polyester yarns in an untwisted state, or it is preferable to use a drawn-aligned yarn formed by drawing and aligning together two or more nylon multi-filament yarns in an untwisted state. It is also preferable to use, as the ground, a composite yarn which is composed of a combination of such a drawn-aligned yarn (at least one auxiliary yarn) and at least one cut resistant yarn. The high multi-polyester yarn is a multi-filament yarn containing a plurality of polyester fibers, each of which is extremely fine and has a low single fiber fineness. In the pile knitted fabric 25, the auxiliary yarn contained in the ground yarn and the pile yarn described below can be made of the same type of material or different types of materials. In the pile knitted fabric 25, for example, a yarn made of the same material as the pile yarn described below can be used as the auxiliary yarn contained in the ground yarn, which is a yarn different from the pile yarn, in combination with the cut resistant yarn or the reinforcing yarn. The ground yarn can be, for example, a composite yarn in which the cut resistant yarn, the reinforcing yarn and the auxiliary yarn are twisted together. The ground yarn can be, for example, a covering yarn in which a combination of the cut resistant yarn and the reinforcing yarn is used as a core material, and one or more auxiliary yarns are wound around the outer periphery of this core material as a sheath yarn. The ground yarn is preferably a double covering yarn, in which for example, the cut resistant yarn is used as a core yarn, the reinforcing yarn is used as a first sheath yarn which is wound around the outer periphery of this core yarn, and the auxiliary yarn is used as a second sheath yarn which is further wound around the outer periphery of the covering yarn formed by the core yarn and the first sheath yarn.

[0034] As the ground yarn, for example, one composite yarn C can be used, which is formed by using two bundled stainless steel wires (bundled two cut resistant yarns) as a core material, one spun yarn or filament yarn (one reinforcing yarn) containing a plurality of aramid fibers as a sheath yarn, and winding the sheath yarn around the outer periphery of the core material. Alternatively, as the ground yarn, for example, a double covering yarn D can be used, which is formed by using one stainless steel wire (one first cut resistant yarn) as a core yarn, one multi-filament yarn (one second cut resistant yarn) containing a plurality of synthetic fibers, each of which contains inorganic particles, as a first sheath yarn, one spun yarn or one multi-filament yarn (one auxiliary yarn) containing a plurality of polyester fibers as a second sheath yarn, and further winding the second sheath yarn around the outer periphery of the covering yarn in which the first sheath yarn is wound around the outer periphery of the core yarn. Alternatively, as the ground yarn, for example, a drawn-aligned yarn E can be used, which is formed by drawing and aligning together the one composite yarn C, and at least one spun yarn or at least one multi-filament yarn each containing a plurality of nylon fibers in an untwisted state. Alternatively, as the ground yarn, for example, a double yarn F can be used, which is formed by twisting the one double covering yarn D and another double covering yarn D. Alternatively, as the ground yarn, for example, a drawn-aligned yarn G can be used, which is formed by drawing and aligning together the double yarn F and at least one spun yarn or at least one multi-filament yarn each containing a plurality of nylon fibers in an untwisted state.

[0035] As described above, there is a case where the ground yarn is composed of two or more yarns, and in this case, the fineness of the ground yarn means the sum of the finenesses of the two or more yarns contained in the ground yarn, i.e., the total fineness. From the viewpoint of further enhancing the cut resistance properties, the fineness (total fineness) of the ground yarn can be, for example, 150 dtex or more, 320 dtex or more, 480 dtex or more, and is preferably 580 dtex or more. In this case, in order to prevent the ground yarn from becoming too hard, the fineness (total fineness) of the ground yarn can be, for example, 1,500 dtex or less, and is preferably 1,300 dtex or less. From a similar viewpoint, and also from the viewpoint of further increasing the flexibility of the pile knitted fabric 25, the fineness (total fineness) of the ground yarn can be, for example, 950 dtex or less, and is preferably 800 dtex or less.

[0036] The pile yarn is a yarn having flexibility capable of forming a plurality of loops pulled out from the ground yarn on the back stitch 25b of the pile knitted fabric 25 (i.e., the inner surface of the glove body 20) to such an extent that the ground yarn is unlikely to come into contact with the wearer's hand, or a yarn composed of, as a constituent unit, a combination of two or more yarns having such flexibility. As the pile yarn, a yarn of one type having such flexibility can be used, or composite yarn composed of a combination of yarns of two or more types each having such flexibility can be used. Examples of the yarn having such flexibility include a spun yarn or a filament yarn containing a plant fiber, an animal fiber, a regenerated fiber, or a relatively soft synthetic fiber. Examples of the plant fiber include a cotton fiber and a hemp fiber. Examples of the animal fiber include a wool fiber, a cashmere fiber, and an alpaca fiber. Examples of the regenerated fiber include a rayon fiber. Examples of the synthetic fiber excluding a hard fiber such as a cut resistant fiber include an acrylic fiber, a nylon fiber, a polyester fiber, and a polyurethane fiber.

[0037] As shown in FIG. 2A and FIG. 2B, in the back stitch 25b of the pile knitted fabric 25, gaps between the plurality of loops formed by the pile yarn can function as the heat insulation layer 252 that retains air on the surface of the wearer's hand and provides an insulating effect to this air. From the viewpoint of further enhancing cold protection properties provided by the heat insulation layer 252, it is preferable to use, as the pile yarn having the above-mentioned flexibility, a yarn of one type selected from the group consisting of an acrylic fiber, a wool fiber, a rayon fiber, and a modified cross-section fiber, or to use a composite yarn made by combining yarns of two or more types selected from this group. The modified cross-section fiber is composed of fibers each having a special cross-sectional shape that does not fall under a general round cross-sectional shape, and examples thereof include a fiber having a cross shape in cross section and a hollow fiber. The modified cross-section fiber can be made of an acrylic resin or a polyester resin. As the pile yarn having the above-mentioned flexibility, it is more preferable to use a filament yarn containing an acrylic fiber from the viewpoint of having both cold protection properties and versatility. Alternatively, from the viewpoint of facilitating the formation of a plurality of loops by the pile yarn in the back stitch 25b of the pile knitted fabric 25 during the raising process, it is preferable to use a spun yarn as the pile yarn having the above-mentioned flexibility, and it is even more preferable to use a spun yarn composed of a plurality of wool fibers or a plurality of acrylic fibers.

[0038] From the viewpoint of increasing the bulk of the heat insulation layer 252 to improve the cold protection performance and further avoiding contact between the ground yarn and the wearer's hand, it is preferable to use, as the pile yarn, a yarn composed of a double yarn formed by twisting two single yarns together, each of the single yarns having the flexibility described above. From the viewpoint that distortion caused by twisting is somewhat offset and the shape of each loop is likely to be stable, it is preferable that the double yarn contained in the pile yarn be a double yarn formed by twisting together two single yarns in different directions. For example, the double yarn is preferably formed by drawing and aligning together an S-twisted single yarn and a Z-twisted single yarn and twisting them together by Z-twisting. From the viewpoint of further increasing the bulkiness or the like of the heat insulation layer 252, it is also preferable to use a yarn which contains a plurality of double yarns and is formed by drawing and aligning together these double yarns as the pile yarn. From the viewpoint of improving the cold protection performance by bulkiness, the fineness (total fineness) of the pile yarn can be, for example, 450 dtex or more, 500 dtex or more, and is preferably 700 dtex or more. From the viewpoint of facilitating knitting of the pile knitted fabric 25, the fineness (total fineness) of the pile yarn can be, for example, 2,000 dtex or less, preferably 1,500 dtex or less, more preferably 1,200 dtex or less.

[0039] From the viewpoint of obtaining excellent heat retention effect of the heat insulation layer 252 formed by a plurality of loops of the pile yarn in the back stitch 25b of the pile knitted fabric 25, it is preferable that the single yarn contained in the pile yarn be loosely twisted yarn. In other words, it is preferable that the pile yarn be a yarn of one type or a combination of yarns of two or more types selected from the group consisting of a loosely twisted single yarn, a double yarn formed by twisting together two single yarns, each of which is loosely twisted, and a triple yarn formed by twisting together three single yarns, each of which is loosely twisted. In other words, it is preferable that the single yarn contained in the pile yarn of the pile knitted fabric 25 be a yarn that has been loosely twisted when the pile knitted fabric 25 is knitted. The single yarn in the pile yarn in the case of being loosely twisted is given a linear shape by the loose twisting, and each loop contained in the plurality of loops of the pile yarn in the pile knitted fabric 25 tends to be stable in an upright state, making it easier to raise the pile knitted fabric 25. Loosely twisted refers to a state in which a yarn is twisted at 500 tpm or less, in which tpm stands for twists per meter, or number of twisting per meter. From a similar viewpoint, it is preferable that the single yarn in the case of being loosely twisted in the pile yarn be a yarn twisted at 400 tpm or less, even more preferably 350 tpm or less. From the viewpoint of preventing fibers contained in the pile yarn from easily falling out of the pile knitted fabric 25, the single yarn in the case of being loosely twisted in the pile yarn can be yarn that has been twisted at, for example, 50 tpm or more when the pile knitted fabric 25 is knitted, or can be a yarn that has been twisted at, for example, 100 tpm or more, and is preferably yarn that has been twisted at, for example, 200 tpm or more. A non-twisted yarn that was not twisted when the pile knitted fabric 25 was knitted is not contained in the loosely twisted yarn. A value of tpm and number of twisting/m herein refers to a value obtained by observing a sample yarn under a microscope, measuring the length of the yarn required for twisting once (m/1 twist) at multiple locations on the yarn, and converting the arithmetic means of the measured values obtained into the number of times the yarn is twisted per 1.0 meter of yarn length (number of twisting/m).

[0040] From the viewpoint of imparting a linear shape to the pile yarn and facilitating the stabilization of the plurality of loops, which form the heat insulation layer 252 in the pile knitted fabric 25, in an upright position on the fabric structure layer 251, it is preferable to use a yarn in which two or more single yarns are twisted together as the pile yarn, for example, it is preferable to use a double yarn described above for the pile yarn, and it is also preferable to use a triple yarn in which three single yarns are twisted together. It is also preferable to use, as the pile yarn, a yarn of one type or a combination of yarns of two or more types selected from the group consisting of this double yarn and this triple yarn.

[0041] From a similar viewpoint, when the pile yarn contains a double yarn formed by twisting together two single yarns or a triple yarn formed by twisting together three single yarns, it is preferable that, when a thread-like cut segment having a length of 100 cm is obtained by cutting out this double yarn or triple yarn in a pile yarn before use in knitting the pile knitted fabric 25 (for example, a pile yarn that has been unwound from a roll wound around a cone or cheese, etc., and is ready for use in knitting the pile knitted fabric 25), and the thread-like cut segment is hung down while having both ends aligned and held together so as not to untwist, the two single yarns in the double yarn or the three single yarns in the triple yarn be twisted together so that the number of intersections (the number of snarling intersections) appearing in the hung-down thread-like cut segment is 6 or less. From a similar viewpoint, the number of intersections (the number of snarling intersections) appearing in this thread-like cut segment is more preferably 5 or less, even more preferably 3 or less. Herein, a thread-like cut segment having a length of 100 cm cut from a double yarn is also referred to as a double yarn thread-like cut segment, and a thread-like cut segment cut having a length of 100 cm cut from a triple yarn is also referred to as a triple yarn thread-like cut segment. FIG. 3A shows a thread-like cut segment 255a in which the number of intersections (the number of snarling intersections) that appear is 2. FIG. 3B shows a thread-like cut segment 255b in which the number of intersections (the number of snarling intersections) that appear is 10. Each of arrows depicted in FIG. 3A and FIG. 3B points to a location where one intersection appears. As shown in FIG. 3B, when the number of intersections (the number of snarling intersections) appearing in the thread-like cut segment is 7 or more, two or more single yarns forming the pile yarn are excessively twisted, so that a plurality of loops formed by the pile yarn are difficult to rise on the fabric structure layer (the plurality of loops are likely to lie on the fabric structure layer), and the heat insulation properties and a soft touch feel provided by the heat insulation layer may be impaired, which is not so desirable.

[0042] From the viewpoint of imparting stiffness to the pile yarn in the same manner as the loose twist described above and obtaining an excellent heat retention effect for the formed heat insulation layer 252, the tensile strength of the pile yarn can be, for example, 1.40 cN/dtex or less, and is preferably 1.30 cN/dtex or less. From the viewpoint of preventing fibers contained in the pile yarn from easily falling out of the pile knitted fabric 25, the tensile strength of the pile yarn can be, for example, 0.50 cN/dtex or more, and is preferably 0.60 cN/dtex or more. The value of the tensile strength herein is a value obtained by a measurement method using chucks in a tensile testing machine (manufactured by Shimadzu Corporation, product name: bench-top precision universal testing machine, model: AGS-500NX) under the following conditions: a length of the yarn to be used as a test piece of 13 cm or more; a room temperature of 25 C.2 C.; a distance between the chucks of 60 mm, and a test speed of 100 mm/min.

[0043] The pile knitted fabric 25 can be a pile knitted fabric made using a plurality of yarns containing, for example, a decorative yarn as well as the above-mentioned ground yarn and pile yarn, as long as the amount is small enough not to violate the object of the present disclosure. From the viewpoint of efficiently enhancing the three elements, that is, the cut resistance properties, the heat insulation properties, and a soft touch feel when worn, it is preferable that the pile knitted fabric 25 be a knit fabric that is pile knitted using a plurality of yarns consisting solely of the ground yarn and the pile yarn. From the viewpoint of enhancing the heat insulation properties and a soft touch feel when worn, the ratio of the fineness of the pile yarn to the fineness of the ground yarn (fineness of the pile yarn (dtex)/fineness of the ground yarn (dtex)) can be, for example, 0.5 or more, is preferably 0.9 or more, more preferably 1.3 or more, even more preferably 1.6 or more. From the viewpoint of enhancing the cut resistance properties, this ratio (fineness of the pile yarn (dtex)/fineness of the ground yarn (dtex)) can be, for example, 4.0 or less, is preferably 3.0 or less, more preferably 2.5 or less, even more preferably 2.0 or less.

[0044] The length of each of the plurality of loops formed by pulling out the pile yarn longer than the ground yarn in the back stitch 25b of the pile knitted fabric 25 can be, for example, 5.0 mm or more, is preferably 6.0 mm or more, more preferably 7.0 mm or more. When the loops are of such a length, the heat insulation layer 252 having a thickness of 1.5 mm or more is likely to be formed by the plurality of loops on the side closer to the back stitch 25b of the pile knitted fabric 25 than the ground yarn, which is preferable from the viewpoint of producing excellent heat retention effect and making it difficult for the ground yarn to come into contact with the wearer's hand. From the viewpoint of ease of knitting the pile knitted fabric 25, the length of each of the plurality of loops formed by the pile yarn in the back stitch 25b can be, for example, 15.0 mm or less, or 13.0 mm or less.

[0045] From the viewpoint of producing excellent heat retention effect and making it difficult for the ground yarn to come into contact with the wearer's hand, the thickness of the heat insulation layer 252 formed by the plurality of loops of the pile yarn in the back stitch 25b of the pile knitted fabric 25 can be, for example, 1.0 mm or more, preferably 1.3 mm or more, more preferably 1.6 mm or more. From the viewpoint of providing the pile knitted fabric 25 that is easy to knit, the thickness of the heat insulation layer 25 formed by the plurality of loops of the pile yarn in the back stitch 25b of the pile knitted fabric 25 can be, for example, 4.0 mm or less, is preferably 3.5 mm or less, more preferably 3.0 mm or less.

[0046] The thickness of the heat insulation layer 252 formed by the plurality of loops described above can be measured by observing a cross section of the pile knitted fabric 25 cut in the thickness direction using a microscope at a magnification of, for example, 20 times. In explaining this measurement method, FIG. 2A and FIG. 2B show microscope images of the pile knitted fabric 25 in cross section cut in the thickness direction in the same manner as each other. To measure the thickness, as shown in FIG. 2A and FIG. 2B, a sample for thickness measurement is prepared by attaching a cardboard 27 with a double-sided tape attached thereto to a surface of the pile knitted fabric 25 on the side of the face stitch 25a, i.e., the surface on the side on which the fabric structure layer 251 composed of the ground yarn and the pile yarn is formed. Then, as shown in FIG. 2A, the thickness of the fabric structure layer 251 in which the ground yarn and the pile yarn are entangled with each other in the pile knitted fabric 25 is measured at four or more locations, and the arithmetic means of the multiple thickness measurements obtained is regarded as the thickness of the fabric structure layer 251. As shown in FIG. 2B, the total thickness of the fabric structure layer 251 and the heat insulation layer 252 formed by the plurality of loops of the pile yarn is measured at four or more locations, and the arithmetic mean of the multiple thickness measurements obtained is regarded as the overall thickness of the pile knitted fabric 25. The thickness of the heat insulation layer 252 formed by the plurality of loops of the pile yarn is calculated by subtracting the thickness of the fabric structure layer 251 (average 1.99 mm in the example shown in FIG. 2A) from the overall thickness of the pile knitted fabric 25 (average 4.06 mm in the example shown in FIG. 2B) (for example, 4.06 mm-1.99 mm=2.07 mm). When measuring the thickness, care should be taken not to include the thickness of the cardboard 27 with the double-sided tape attached thereto.

[0047] In addition to having a thickness within any of the ranges described above, it is preferable that the heat insulation layer 252 have a plurality of loops raised by the pile yarn that constitutes the heat insulation layer 252. The heat insulation layer 252 having a plurality of loops of the pile yarn in a raised state is preferable from the viewpoints that it further improves the softness of a touch feel on the inner surface of the glove body 20 compared to a case where they are not in the raised state, and further improves the heat insulation properties by increasing the volume of air retained in the heat insulation layer 252. The raising of the plurality of loops by the pile yarn can be carried out by a method known to those skilled in the art. For example, a method can be used in which a brush is used to scratch and raise a plurality of loops of the pile yarn by manual or mechanical processing.

[0048] Compared to a knitted fabric made only of the cut resistant ground yarn, the pile knitted fabric 25 does not have high cut resistance overall because it contains the pile yarn. Instead, from the viewpoint of allowing the pile knitted fabric 25 to have a thickness to ensure the cut resistance properties, the pile knitted fabric 25 is a knitted fabric, in which a plurality of yarns containing the ground yarn and the pile yarn are pile knitted to have a gauge of less than 10, and preferably a knitted fabric, in which those yarns are pile knitted to have a gauge of 8 or less. For example, the pile knitted fabric 25 can be knitted using a knitting machine (preferably a glove knitting machine) designed to enable any gauge condition to fall within the range of 5 gauge or more and less than 10 gauge. Further, the smaller the gauge number, the larger the stitches of the pile knitted fabric 25, so that the thickness of the ground yarn and the thickness of the pile yarn suitable for the glove knitting machine become larger. For this reason, from the viewpoint of making it easy to further impart a soft touch feel to the pile knitted fabric 25, it is desirable that the pile knitted fabric be a knitted fabric in which a plurality of yarns containing the ground yarn and the pile yarn are pile knitted to have a gauge of, for example, 5 or more, preferably 6 or more.

[0049] From the viewpoint of further improving the cut resistance properties, the heat insulation properties, and a soft touch feel when worn, the density of the pile knitted fabric 25 is preferably 7 or more, more preferably 8 or more in terms of the number of stitches per 1.0 inch width in the course direction. From a similar viewpoint, the density of the pile knitted fabric 25 is preferably 10 or more, more preferably 13 or more in terms of the number of stitches per 1.0 inch width in the wale direction. From the viewpoint of improving the flexibility of the glove body 20, the density of the pile knitted fabric 25 is preferably 15 or less, more preferably 12 or less in terms of the number of stitches per 1.0 inch width in the course direction. From a similar viewpoint, the density of the knitted pile fabric 25 is preferably 26 or less, more preferably 20 or less in terms of the number of stitches per 1.0 inch width in the wale direction. Herein, the number of stitches indicated as the density of the pile knitted fabric 25 is a value obtained by counting the number of stitches from the appearance of a part of the pile knitted fabric 25 of the glove body 20, which part forms a center of the palm part 21b. The wale direction is the warp direction of the pile knitted fabric 25, and the course direction is the weft direction of the pile knitted fabric 25.

[0050] As an index of the level of the cut resistance properties of the glove 10a, the cut resistance level as an evaluation result of a TDM test in accordance with EN ISO 13997 can be used. When the glove 10a is used for applications in which a certain degree of the cut resistance properties is sufficient, the cut resistance level of the pile knitted fabric 25 can be, for example, level C or higher, and is preferably level D or higher. When the glove 10a is used for applications in which a relatively soft touch feel is more important than the cut resistance properties, the cut resistance level of the pile knitted fabric 25 can be, for example, level D or lower. The TDM test involves: placing a test piece of the pile knitted fabric 25 on a sample table located below a flat blade; applying a load from below to the sample table so as to push the sample table up towards the flat blade while sliding the flat blade in one direction, thereby measuring the applied load and the distance the flat blade slides until the test piece is penetrated; and evaluating the cut resistance level of the test piece from the actual measurement value. The estimated load on the flat blade to be required to penetrate the test piece when sliding the flat blade 20 mm is 2 N or more for level A, 5 N or more for level B, 10 N or more for level C, 15 N or more for level D, 22 N or more for level E, and 30 N or more for level F.

[0051] Conventionally, when trying to improve the cut resistance properties of a glove, it is generally considered by those skilled in the art to improve the glove by changing the yarn used in the glove fabric to a yarn having excellent cut resistance properties. In this case, an improvement can be considered in which the amount of the cut resistant yarn used per unit volume in the glove fabric is increased. However, the cut resistant yarn has a hard touch feel. As a result, a glove improved along these lines have a problem that, when wearing the glove, the cut resistant yarn causes an increased hard and scratchy touch feel, which may be uncomfortable for the wearer.

[0052] In contrast, the glove 10a having the glove body 20 described above in this disclosure has the cut resistance properties caused by the ground yarn, and therefore can be used as a cut resistant glove. The glove 10a further has heat insulation properties caused by the plurality of loops of the pile yarn, and is less prone to the hard touch feel caused by the ground yarn, making it suitable for use as a cut resistant glove to be worn when handling sharp objects in cold environments. For example, the glove 10a is expected to be suitably used as a working glove in mines or offshore oil fields in cold regions or seasons.

[0053] From the viewpoint of further enhancing suitability as a working glove in cold environments compared to the above-described glove 10a, a cut resistant glove 10b according to another embodiment (hereinafter also referred to as glove 10b) which will be described below mainly referring to FIG. 4A (back side of the hand) and FIG. 4B (palm side) is preferable. The glove 10b includes the glove body 20 (see FIG. 1A and FIG. 1B) and an outer glove 30 (see FIG. 4A and FIG. 4B). The glove body 20 of the glove 10b is configured similarly to the glove body 20 of the glove 10a described above, and therefore the same description will not be repeated. The outer glove 30 of the glove 10b is joined to the glove body 20 on the side of the face stitch 25a of the pile knitted fabric 25 of the glove body 20 so as to cover at least a part of the glove body 20.

[0054] The outer glove 30 of the glove 10b is configured to include at least one fabric 31. The at least one fabric 31 can be one fabric 31 or can be a plurality of fabrics including the fabric 31 as each fabric. The fabric 31 can be made from a yarn of one type or yarns of two or more types that are generally used for making a glove, and can be made by known knitting techniques. The fabric 31 contained in the outer glove 30 can be knitted, for example, using a glove knitting machine having a gauge of 10 or more and 26 or less, using a plain knitting or plating knitting method, but is not limited to this example. The fineness of a yarn of one type or the total fineness of yarns of two or more types used to knit the fabric 31 contained in the outer glove 30 can be a thickness that can be used on a glove knitting machine having a gauge of 10 or more and 26 or less, and for example, can be 50 dtex or more and 1,500 dtex or less, but is not limited to this example. The outer glove 30 can be made by cutting a textile material into a glove shape and sewing it.

[0055] The outer glove used can be a glove made of only the above-mentioned fabric 31, for example. Alternatively, from the viewpoint of imparting anti-slip properties or the like to the glove 10b, it is preferable that at least one resin coating layer 40 be laminated on at least a part of the outer surface (the opposite side of the fabric to the inner side facing the glove body 20) of the fabric 31 of the outer glove 30. The at least one resin coating layer 40 can be composed of, for example, only the one resin coating layer, but is preferably composed of two or more resin coating layers.

[0056] In the glove 10b shown in FIG. 4A and FIG. 4B, at least one resin coating layer 40 has a two-layer structure composed of a first resin coating layer 41 and a second resin coating layer 42. The first resin coating layer 41 is laminated on a part of the outer surface of the fabric 31 of the outer glove 30. The second resin layer 42 is further laminated on a part of the outer surface of the first resin coating layer 41. Specifically, FIGS. 4A and 4B show an example in which the first resin coating layer 41 is laminated on the entire area of the part of the outer glove 30 corresponding to the body bag 21 and the finger bag 22 of the glove body 20 shown in FIG. 1A and FIG. 1B, and on a part of the portion corresponding to the sleeve part 23. FIG. 4A and FIG. 4B show an example in which the second resin coating layer 42 is laminated only on a part of a portion 31a corresponding to the back part 21a of the glove body 20 and a part of the portion corresponding to the finger bag 22 of the glove body 20 on the back side of the hand shown in FIG. 1A, whereas the second resin coating layer 42 is laminated on the entire area of the portion 31b corresponding to the palm part 21b, the entire area of the part corresponding to the finger bag 22, and a part of the portion corresponding to the sleeve part 23 on the palm side shown in FIG. 1B. The position, shape, etc. of the at least one resin coating layer to be laminated on the fabric of the outer glove are not limited to the examples shown in FIG. 4A and FIG. 4B.

[0057] The resin forming the at least one resin coating layer 40 is not particularly limited as long as it is a resin material that can be used to form a resin coating layer in gloves such as conventional supported gloves. The resin forming at least one resin coating layer 40 can be, for example, rubber derived from latex.

[0058] From the viewpoint of preventing the hand of the wearer of the glove 10b from getting sweaty, at least one resin coating layer 40 can have a part composed only of a porous resin coating layer made of foamed resin and arranged to be visible from the outside in the appearance of the glove 10b. Such a porous resin coating layer has excellent breathability and moisture absorption properties. Therefore, when a relatively large area of the outer glove 30 is covered only with such a porous resin coating layer, the hand of the wearer of the glove 10b is prevented from getting sweaty. In the example shown in FIG. 4A and FIG. 4B, the portion 31a of the outer glove 30 corresponding to the back part 21a of the glove body 20 is covered only with the porous first resin coating layer 41 made of foamed resin, so that the hand of the wearer is prevented from getting sweaty.

[0059] Of the at least one resin coating layer 40, an exposed part that is visible from the outside in the appearance can function as an anti-slip layer when the wearer of the glove 10b performs hand work. Although not shown, when the at least one resin coating layer consists solely of one resin coating layer, the one resin coating layer can be considered to be an outermost layer, the outer surface of which is exposed in a state of being visible from the outside in the appearance over its entire area. From the viewpoint of further imparting anti-slip properties, it is preferable that the outermost layer of the at least one resin coating layer 40 be a non-porous resin coating layer formed by a non-foamed resin coating. In the example shown in FIG. 4A and FIG. 4B, the entire area of the portion 31b of the outer glove 30 corresponding to the palm part 21b of the glove body 20 and the entire area of the finger bag 22 of the glove body 20 on the palm side have the second resin coating layer 42 made of a non-foamed resin and arranged as the outermost layer, so that a non-slip effect is easily exhibited when the wearer of the glove 10b grasps an object. Further, in the part where the non-porous second resin coating layer 42 made of a non-foamed resin is formed as the outermost layer, the porous first resin coating layer 41 is coated with the second resin coating layer 42, which is preferable from the viewpoint that the porous first resin coating layer 41, which is relatively easily damaged, is protected by the non-porous second resin coating layer 42, which is relatively less likely to be damaged, and also from the viewpoint that the heat insulating properties are enhanced by the second resin coating layer 42, making it difficult for body heat to be lost from the hand of the wearer of the glove 10b to a cold atmosphere.

[0060] The thickness of the one resin coating layer forming the exposed part of the at least one resin coating layer 40, which is visible from the outside in the appearance, is not particularly limited unless contrary to the object of the present disclosure. From the viewpoint of configuring the glove 10b to allow the wearer's hand to move easily, when one resin coating layer of the at least one resin coating layers 40, which forms the exposed part, is made of a foamed resin, the thickness of the one resin coating layer (for example, when the first resin coating layer 41 shown in FIG. 4A is made of a foamed resin, the thickness of the first resin coating layer 41 exposed on the portion 31a) is preferably 2.0 mm or less, more preferably 1.5 mm or less. From a similar viewpoint, when one resin coating layer of the at least one resin coating layer 40, which forms the exposed part, is made of a non-foamed resin, the thickness of the one resin coating layer (for example, when the second resin coating layer 42 shown in FIG. 4B is made of a non-foamed resin, the thickness of the second resin coating layer 42 exposed on the palm part 31 b) is preferably 1.0 mm or less, more preferably 0.5 mm or less.

[0061] As a manufacturing method for the outer glove configured such that the at least one resin coating layer laminated on at least a part of the outer surface of the fabric of the outer glove consists solely of one resin coating layer, the outer glove can be manufactured by: knitting a glove base without any resin coating layer laminated thereon; placing the glove base on a hand mold; immersing at least a part of the glove base together with the hand mold in a resin solution; and drying the glove base after removing it from the resin solution, thereby forming one resin coating layer on the outer surface of the glove base. As a manufacturing method for the outer glove configured such that the at least one resin coating layer laminated on at least a part of the outer side of the fabric of the outer glove is composed of two resin coating layers, the outer glove can be manufactured by: knitting a glove base without any resin coating layer laminated thereon; placing the glove base on a hand mold; immersing at least a part of the glove base together with the hand mold in a first resin solution; drying the glove base after removing it from the first resin solution to form a first resin coating layer, immersing the glove base together with the hand mold in a second resin solution to have at least a part of the first resin coating layer immersed therein; and drying the glove base after removing it from the second resin solution to form a second resin coating layer.

[0062] In the glove 10b shown in FIG. 4A and FIG. 4B, the outer glove 30 is joined to the glove body 20 so as to cover the entire area on the side (outer side) of the face stitch 25a of the glove body 20. For example, the glove 10b can be manufactured by inserting the glove body 20 into the outer glove 30 and joining a part of the outer side (the side of the face stitch 25a) of glove body 20 to a part of the inner side of outer glove 30. Therefore, in the appearance of the glove 10b shown in FIG. 4A and FIG. 4B, the face stitch 25a of the glove body 20 is covered by the outer glove 30 and cannot be visually observed. When manufacturing the glove 10b including the outer glove 30 having at least one resin coating layer 40 laminated thereon as described above, the glove body 30 is inserted into the outer glove 30 on which the at least one resin coating layer 40 has been laminated.

[0063] The joining part between the glove body 20 and the outer glove 30 is not particularly limited unless contrary to the object of the present disclosure. From the viewpoint of making it easy for the wearer of the glove 10b to move his or her fingers, it is preferable that the fingertip part (finger bag 22) of the glove body 20 and a part of the outer glove 30 covering the fingertip part of the glove body 20 be joined together, and in this case, it is even more preferable that a part of each of the first to fifth finger bags (22a to 22e) on the palm side of the glove body 20 and the fingertip part of the outer glove 30 corresponding to this part be joined together. From the viewpoint of making it easy to insert the wearer's hand into the glove body 20 when wearing the glove 10b, it is preferable that the end portion of the sleeve part 23 of the glove body 20 and the part of the outer glove 30 corresponding to this end portion be joined together. From the viewpoint of preventing the glove body 20 from rolling up inside the outer glove 30 when the glove 10b is worn, it is preferable that a portion of the palm part 21b (FIG. 1B) of the glove body 20 that is relatively close to the boundary with the sleeve part 23 be joined to a portion of the outer glove 30 that corresponds to this portion.

[0064] The method for joining the glove body 20 and the outer glove 30 is not particularly limited unless contrary to the object of the present disclosure, and can be any means that is usable to join the glove body (inner glove) and the outer glove together in a conventional double glove. For example, when joining the fingertip part (finger bag 22) of the glove body 20 to the corresponding part of the outer glove 30, or when joining the palm part 21a of the glove body 20 to the corresponding part of the outer glove 30, the joining can be performed using a hot melt adhesive. For example, when joining the sleeve part 23 of the glove body 20 to the corresponding part of the outer glove 30, they can be joined together by sewing using a lock sewing machine or the like.

[0065] FIG. 4A and FIG. 4B show the glove 10b that is designed to be worn to cover the wearer's hand. Although not shown, in yet another embodiment, it is possible to change the shape of the outer glove 30 from the shape shown in FIG. 4A and FIG. 4B to form a glove in a shape that can be used as a mitten, or a glove with an arm cover that is worn on at least a part of the wearer's arm including the hand. The part of the outer glove where at least one resin coating layer is formed is not limited to the part shown in FIG. 4A and FIG. 4B. As another example (not shown), the at least one resin coating layer can be formed on the entire area of the part of the outer glove corresponding to the palm part of the inner glove (part covering the palm part), or can be formed on the entire area of the part of the outer glove corresponding to the finger bag of the inner glove (part covering the finger bag).

[0066] Although the right-hand glove (10a, 10b) is shown in FIG. 1A, FIG. 1B, FIG. 4A, and FIG. 4B, in still other embodiments according to the present disclosure, the glove can be the left-hand glove, or can be a set of cut resistant gloves including the right-hand glove and the left-hand glove. A glove body in a glove in the case of being used in an application in which somewhat inferior cut resistance properties are acceptable compared to the above-mentioned glove (10a, 10b) can be modified to a glove body having a pile knitted fabric in which a plurality of yarns containing the ground yarn and the pile yarn are pile knitted to have a gauge of 10 or more.

[0067] The cut resistant glove according to this embodiment is as described above, but the present disclosure is not limited to the above embodiment, and various modifications are possible without departing from the gist of the present disclosure. Further, the cut resistant glove according to the present disclosure is not limited to the effects of the above-described embodiments. That is, the embodiments according to the present disclosure should be considered in all respects as illustrative and not restrictive. The scope of the present disclosure is indicated by the claims, rather than by the foregoing description.

EXAMPLES

[0076] The present disclosure will be described below with reference to examples, but the present disclosure is not limited to these examples.

[0077] A double covering yarn A1 having the following configuration was prepared.

[0078] Double covering yarn A1: one stainless steel wire having a diameter of 35 m (equivalent to a fineness of 74 dtex) was used as a core yarn (cut resistant yarn), a para-aramid spun yarn having a fineness equivalent to 236 dtex spun from a plurality of para-aramid fibers was used as a first sheath yarn (reinforcing yarn), and a polyester spun yarn having a fineness of 295 dtex was used as a second sheath yarn (auxiliary yarn). Then, the first sheath yarn was wound around the core yarn at 1,000 times/m in the Z direction to cover it, and then the second core yarn was wound therearound at 1,000 times/m in the S direction to cover it, to form a double covering yarn A1. The total fineness of this double covering yarn A1 was equivalent to 605 dtex.

[0079] Further, a double yarn B1 and a single yarn B2 having the following configuration were prepared.

[0080] Double yarn B1: As the double yarn B1 formed by twisting together two single yarns, an acrylic spun yarn having an acrylic count of 2/28 and a total fineness equivalent to 714 dtex was prepared. This double yarn B1 is formed by drawing and aligning together an acrylic spun yarn having an acrylic count of 1/28 twisted 435 times per meter in the S direction and a fineness equivalent to 357 dtex, and an acrylic spun yarn having an acrylic count of 1/28 twisted 435 times per meter in the Z direction and a fineness equivalent to 357 dtex, and twisting them 235 times per meter in the Z direction, to form a double yarn having total fineness equivalent to 714 dtex.

[0081] Single yarn B2: An acrylic spun yarn having an acrylic count of 1/28 and a fineness equivalent to 357 dtex was prepared as a single yarn B2. This single yarn B2 was twisted 325 times per meter in the Z direction.

Example 1

[0082] In Example 1, two double covering yarns A1 were drawn and aligned together to form a drawn-aligned yarn having a total fineness equivalent to 1210 dtex. This drawn-aligned yarn was used as the ground yarn. In Example 1, the double yarn B1 was used as the pile yarn. Based on this, a glove according to Example 1 was experimentally produced. Immediately before the experimental production was made, a double yarn thread-like cut segment was obtained from this pile yarn (double yarn B1) by the above-mentioned method, and the number of snarling intersections was measured. As shown in FIG. 3A, the number of snarling intersections was 2. In Example 1, thereafter, the ground yarn and the pile yarn were pile-knitted at a gauge of 7 using a glove knitting machine SPG-R manufactured by Shima Seiki Mfg. Ltd., to produce a seamless knitted glove made only of the pile knitted fabric. In the knitted glove according to Example 1, the pile yarn formed loops that were pulled out longer than the ground yarn in the back stitch of the pile knitted fabric. In the pile knitted fabric from which the knitted glove of Example 1 was knitted, the above-mentioned ratio (fineness of the pile yarn (dtex)/fineness of the ground yarn (dtex)) was 0.59.

[0083] When the glove of Example 1 was worn on the hand, no scratchy touch feel was felt, and a soft texture was felt. Regarding the density of the pile knitted fabric of the glove of Example 1, the number of stitches in the course direction was 9.2 per 1.0 inch and the number of stitches in the wale direction was 16.5 per 1.0 inch, measured by the above-mentioned measurement method. When the cross section of the glove of Example 1 cut in the thickness direction was observed under a microscope, the length of each loop included in the plurality of loops formed by the pile yarn was 9.0 mm on average when measuring four locations as shown in FIG. 2A, and the thickness of only the heat insulation layer formed by the plurality of loops was 2.37 mm on average when measuring six locations as shown in FIG. 2B. A thermometer sensor was set on the inner surface of the glove of Example 1, and 800 g of cylindrical ice with a diameter of 8 cm was placed on the outer surface of the glove to measure the temperature on the inner surface of the glove. The temperature was 23.7 C. before the ice was placed, and dropped to 8.1 C. 3 minutes after the ice was placed. The abrasion resistance of the glove of Example 1 was evaluated as level E in the above-mentioned test in accordance with EN ISO 13997.

Example 2

[0084] In Example 2, two double covering yarns A1 were drawn and aligned together to form a drawn-aligned yarn having a total fineness equivalent to 1210 dtex, and this drawn-aligned yarn was used as the ground yarn. In Example 2, two single yarns B2 were drawn and aligned together to form a drawn-aligned yarn having a total fineness equivalent to 714 dtex. This drawn-aligned yarn was used as the pile yarn. Based on this, a glove according to Example 2 was experimentally produced. Immediately before the experimental production was made, a thread-like cut segment was obtained from this pile yarn (a drawn-aligned yarn formed by drawing and aligning together two single yarns B2) by the above-mentioned method, and the number of snarling intersections was measured. As shown in FIG. 3B, the number of snarling intersections was 10. In Example 2, thereafter, the ground yarn and the pile yarn were pile-knitted at a gauge of 7 using the glove knitting machine SPG-R described above to produce a seamless knitted glove made only of the pile knitted fabric. In the knitted glove according to Example 2, the pile yarn formed loops that were pulled out longer than the ground yarn in the back stitch of the pile knitted fabric.

[0085] When the glove of Example 2 was worn on the hand, a somewhat scratchy touch feel was felt. Regarding the density of the pile knitted fabric of the glove of Example 2, the number of stitches in the course direction was 9.0 per 1.0 inch and the number of stitches in the wale direction was 16.5 per 1.0 inch, measured by the above-mentioned measurement method. When the cross section of the glove of Example 2 cut in the thickness direction was observed under a microscope, the length of each loop included in the plurality of loops formed by the pile yarn was 8.00 mm on average, and the thickness of only the heat insulation layer formed by the plurality of loops was 1.87 mm on average. A thermometer sensor was set on the inner surface of the glove of Example 2, and 800 g of cylindrical ice with a diameter of 8 cm was placed on the outer surface of the glove to measure the temperature on the inner surface of the glove. The temperature was 23.6 C. before the ice was placed, and dropped to 6.8 C. 3 minutes after the ice was placed.

[0086] In Example 2, a pile knitted fabric was knitted under conditions similar to those in Example 1, but the pile yarn used in Example 2 was more susceptible to snarling (had a number of snarling intersections being greater), had a length of each observed loop being shorter, and had a thickness of the heat insulation layer being thinner than the pile yarn used in Example 1. It is believed that due to these factors, the heat insulation properties of Example 2 was somewhat lower than that of Example 1.
