DESCRIPTION OF EMBODIMENTS

(8) <1. Fastener Tape>

(9) The present invention is intended for the woven fastener tape for a slide fastener including an element mount section and a tape main body section. The element mount section is a portion where elements are mounted, and the tape main body section is a portion that is sewn to a body of an article. A side edge of the tape main body section of the fastener tape may further have a selvage section provided with a selvage yarn for preventing yarns from getting loose. The element mount section may have a core string section along a longitudinal direction of the fastener tape, and the core string section is used when injection elements or metal elements are mounted.

(10) In the fastener tape according to the present invention, the tape main body section has a mesh section. The framework of the mesh section is formed by sets of three or more warp yarns and sets of three or more weft yarns, and has a mesh structure with an opening formed among the sets of warp yarns and the sets of weft yarns. The framework formed by the warp yarns and the weft yarns plays a role of reinforcing the fastener tape, and the opening plays a role of increasing the air permeability. In the mesh section, the interlacing density of the outermost warp yarns and weft yarns is respectively higher than the interlacing density of the warp yarns and the weft yarns that are on the inner side of the outermost yarns in each set of warp yarns and weft yarns. In other words, the two warp yarns that are on the right and left sides out of the warp yarns in each set have higher interlacing density than the warp yarns that are on the inner side of those yarns, and similarly, the two weft yarns that are on the top and bottom sides out of the weft yarns in each set have higher interlacing density than the weft yarns that are on the inner side of those yarns.

(11) The outermost warp yarns and weft yarns in each set of the warp yarns and the weft yarns correspond to the warp yarns and the weft yarns that define each of the openings, and when the interlacing density of those yarns is high, the shape of the opening can be maintained to prevent the mesh deviation. Moreover, when, in each set of the warp yarns and the weft yarns, the interlacing density of the inner warp yarns and weft yarns is lower than that of the outermost warp yarns and weft yarns, the force operates to pull the warp yarns and the weft yarns toward the inside of each set, suppressing the mesh deviation further. On the contrary, when the interlacing density of the inner warp yarns and weft yarns is higher than or equal to that of the outermost warp yarns and weft yarns, the warp yarns and the weft yarns are easily moved outward from each set, and in this case, the mesh deviation easily occurs.

(12) Here, the interlacing density of the warp yarn is based on the number of times of interlacing with the weft yarns through the floating and sinking until the warp yarn traveling in the longitudinal direction of the fastener tape crosses the weft yarns for a certain number of times. Moreover, the interlacing density of the weft yarn is based on the number of times of interlacing with the warp yarns through the floating and sinking until the weft yarn traveling in the width direction of the fastener tape crosses the warp yarns for a certain number of times. As the number of interlacing times is larger, the interlacing density is higher. For example, the 1/1 (warp yarn/weft yarn) weave structure, in which the warp yarn crosses over one weft yarn and then crosses under one weft yarn, has smaller interlacing density than the 2/2 weave structure, in which the warp yarn crosses over two weft yarns and then crosses under two weft yarns.

(13) In the present invention, each set of the warp yarns and the weft yarns forming the framework of the mesh structure is composed of three or more warp yarns and three or more weft yarns. This is for the purpose of securing the strength and forming the mesh structure that suppresses the mesh deviation with the weave structure (the mesh deviation refers to the deviation of the warp yarn and/or the weft yarn in the width direction or the longitudinal direction of the fastener tape). Note that when the number of the warp yarns and the weft yarns in each set is excessively large, the mesh deviation occurs more easily or the proportion of the opening area in the fastener tape becomes small to deteriorate the air permeability; thus, each set is preferably composed of three to five warp yarns and three to five weft yarns.

(14) Therefore, in a preferred embodiment of the fastener tape of the present invention, the outermost warp yarns and weft yarns in each set of the warp yarns and the weft yarns are selected from the 1/1, 1/2, and 2/1 weave structures, and the warp yarns and the weft yarns that are on the inner side of the outermost yarns are selected from the 3/3 and 4/4 weave structures.

(15) Here, the 1/1 weave structure of the warp yarn refers to the weave structure in which the warp yarn crosses over one weft yarn and crosses under one weft yarn, the 1/2 weave structure of the warp yarn refers to the weave structure in which the warp yarn crosses over one weft yarn and crosses under two weft yarns, the 2/1 weave structure of the warp yarn refers to the weave structure in which the warp yarn crosses over two weft yarns and crosses under one weft yarn, the 3/3 weave structure of the warp yarn refers to the weave structure in which the warp yarn crosses over three weft yarns and crosses under three weft yarns, and the 4/4 weave structure of the warp yarn refers to the weave structure in which the warp yarn crosses over four weft yarns and crosses under four weft yarns. Similarly, the 1/1 weave structure of the weft yarn refers to the weave structure in which the weft yarn crosses over one warp yarn and crosses under one warp yarn, the 1/2 weave structure of the weft yarn refers to the weave structure in which the weft yarn crosses over one warp yarn and crosses under two warp yarns, the 2/1 weave structure of the weft yarn refers to the weave structure in which the weft yarn crosses over two warp yarns and crosses under one warp yarn, the 3/3 weave structure of the weft yarn refers to the weave structure in which the weft yarn crosses over three warp yarns and crosses under three warp yarns, and the 4/4 weave structure of the weft yarn refers to the weave structure in which the weft yarn crosses over four warp yarns and crosses under four warp yarns.

(16) In each set of the warp yarns and the weft yarns that form the framework of the mesh structure, the dimension of the weft yarn set in the longitudinal direction of the fastener tape is preferably larger than that of the warp yarn set in the width direction of the fastener tape. In other words, in each set of the warp yarns and the weft yarns that form the framework of the mesh structure, the total thickness of the weft yarns is preferably larger than the total thickness of the warp yarns. Further, the number of weft yarns is preferably larger than the number of warp yarns. In the fastener tape, the crosswise tensile strength is considered more important than the longitudinal tensile strength. In this point, the crosswise tensile strength can be increased by increasing the total thickness of the weft yarns as compared with the total thickness of the warp yarns or using more weft yarns than the warp yarns. In a preferred embodiment of the fastener tape of the present invention, each set of the warp yarns and the weft yarns that form the framework of the mesh structure is composed of three warp yarns with four weft yarns, four warp yarns with five weft yarns, or three warp yarns with five weft yarns.

(17) The size of the opening of the mesh section can be adjusted by changing the intervals among the sets of the warp yarns and the weft yarns. When the opening area is increased, the air permeability is improved but the strength of the fastener tape tends to deteriorate. Thus, the opening area may be set as appropriate in consideration of the air permeability and the strength. As an example, the area of each opening may be 0.36 to 6 mm.sup.2, and is preferably 1 to 4 mm.sup.2.

(18) The space among the frameworks of the mesh section composed of the warp yarns and the weft yarns serves as the opening; thus, the opening is basically rectangular or square in shape. In particular, the rectangular shape that is longer in the width direction of the fastener tape than in the longitudinal direction of the fastener tape is preferable even though the area is the same. This is because such a rectangular shape makes the density of the weft yarns relatively higher, so that the horizontal pulling strength of the fastener tape can be increased. For example, the opening can have an aspect ratio of 1:1.1 to 3.0, typically 1:1.2 to 2.0.

(19) In one embodiment of the fastener tape according to the present invention, the tape main body section can be divided into a first section that is close to the element mount section, and a second section that is distant from the element mount section. The first section can be composed of the mesh section and the second section can be composed of a weave structure with higher weaving density than the mesh section. Thus, for example, the first section can be left unsewn to a body of a product for securing the air permeability, while the second section can be sewn to the body of the product with high sewing strength. Here, the weaving density refers to the weight per unit area of the fastener tape.

(20) In a preferred embodiment of the fastener tape according to the present invention, the warp yarns of the first section are more twisted than the warp yarns of the second section. Since the first section is the mesh section, the opening thereof is preferably secured certainly in terms of air permeability. In this point, the coverage of the opening can be suppressed because the use of the more twisted warp yarns can suppress the deformation of the yarns to cause the collapse. The use of the twisted yarns can secure the strength of the opening and this contributes to the prevention of the mesh deviation. On the other hand, the use of less twisted yarns for the second section can suppress the excessive hardness of the fastener tape, whereby the soft texture can be obtained.

(21) Similarly, in a preferred embodiment of the fastener tape according to the present invention, the weft yarns are more twisted than the warp yarns of the second section. In the structure of the woven fabric, the weft yarns generally run across the fastener tape in the width direction thereof; therefore, the same yarns are usually used as the weft yarns in the first section and the second section. Thus, the use of weft yarns that are more twisted than the warp yarns of the second section can secure the opening for the mesh structure in the first section and can suppress the excessive hardness of the fastener tape in the second section, whereby the soft texture can be obtained.

(22) The aforementioned idea for the second section of the tape main body section similarly applies to the element mount section; the element mount section can be composed of the weave structure with higher weaving density than the mesh section. The use of warp yarns, which are less twisted than the yarns of the mesh section, for the element mount section can suppress the excessive hardness of the fastener tape, whereby the soft texture can be obtained.

(23) For securing the opening in the mesh section, one of or both the warp yarns and the weft yarns of the mesh section preferably have a twisting coefficient of 2.0 T/M (twists/meter) or more per dtex, typically 2.0 to 3.0 T/M. From another perspective, the yarns are preferably twisted for 400 times or more, and more preferably 500 times or more, and typically about 400 to 600 times per meter. One yarn can be composed of a monofilament or a multifilament formed by binding two or more monofilaments, or further a plurality of multifilaments.

(24) The warp yarns of the first section are preferably thinner than the warp yarns of the element mount section and the second section. Since the first section is the mesh section, the use of thin yarns is advantageous for increasing the opening. Meanwhile, the use of thick yarns for the element mount section and the second section is advantageous in that the tape can have a certain degree of thickness and the texture is favorable. In the element mount section, moreover, the thickness of the tape suppresses the leakage of molten material or the like when the fastener element is formed by injection molding. Specifically, the fineness of one warp yarn used in the mesh section is preferably, for example, 84 to 560 dtex, and more preferably 110 to 330 dtex. The fineness of one warp yarn used in the element mount section and the second section is preferably, for example, 160 to 660 dtex, and more preferably 330 to 560 dtex. The weft yarn is preferably as thick as the warp yarn in the mesh section.

(25) The material for the yarns used in the fastener tape according to the present invention may be conventionally used polyester, nylon, polypropylene, acrylic, or the like, and is preferably polyester because polyester is easily sewn and has high material strength.

(26) Here, FIG. 1 depicts a weaving structure of a fastener tape (100) according to a first embodiment of the present invention. This fastener tape (100) has an element mount section (101), a tape main body section (102), and a selvage section (103) arranged in this order. The element mount section (101) is provided with a core string section (104) for increasing the mount strength when the injection element or the metal element is mounted. The tape main body section (102) is composed of a first section (105) with a mesh structure, which is close to the element mount section (101), and a second section (106) with a high weaving density, which is distant from the element mount section (101).

(27) The first section (105) is formed using warp yarns and weft yarns with 210 dtex and a twisting coefficient of 2.48 T/M. Therefore, the yarns that are twisted by approximately 520 times per meter are used. In the first section (105), the framework of the mesh structure of the first section is composed of sets of warp yarns and weft yarns, each set consisting of three warp yarns and three weft yarns. In the present invention, two yarns constitute one weft yarn and in FIG. 1 and six weft yarns constituting a set are counted as three yarns. Of the three warp yarns constituting a set of warp yarns, two warp yarns on the right and left sides (the outermost warp yarns in each set) are the 1/1 weave structure, and the central warp yarn (inner warp yarn in each set) is the 3/3 weave structure. Of the three weft yarns constituting a set of weft yarns, two weft yarns on the top and bottom sides (the outermost weft yarns in each set) is the 1/1 weave structure, and the central weft yarn (inner weft yarn in each set) is the 3/3 weave structure. An opening 107 is formed among two adjacent sets of warp yarns (set A and set B) and two adjacent weft yarns (set C and set D). Here, the warp yarns and the weft yarns adjacent to the opening 107 are the outermost warp yarns in the set A and the set B, and the outermost weft yarns in the set C and the set D. In each set of the warp yarns, the interlacing state between the outermost warp yarn and the outermost weft yarn is in the opposite relation to the interlacing state between the inner warp yarn and the outermost weft yarn. For example, in the case where the inner warp yarn goes on the front side of the outermost weft yarn in each set of the warp yarns, the outermost warp yarn goes on the back side of the outermost weft yarn. This similarly applies to the weft yarns. In other words, in each set of the weft yarns, the interlacing state between the outermost weft yarn and the outermost warp yarn is in the opposite relation to the interlacing state between the inner weft yarn and the outermost warp yarn. This similarly applies to the embodiments described below though the number of yarns and the weave structure may be different. When the warp yarns and the weft yarns have such a structure, the effect of preventing the mesh deviation can be increased. Each opening (107) of the first section is a rectangle with a horizontal length of 2 mm and a vertical length of 1.2 mm.

(28) In the element mount section (101) and the second section (106), the warp yarns and the weft yarns are the combination of the 1/1 and 2/2 weave structures, which plays a role of fixing the position of the mesh section. Other weave structures are also applicable. Note that the number of the core strings is not limited to one but may be two. The element mount section (101) and the second section (106) employ the warp yarns with 300 dtex, which have been false twisted. The false twisted yarn is the yarn that has been twisted in one direction and then in the opposite direction, so that the yarn is hardly twisted. Therefore, the number of twists per meter is smaller than that of the warp yarn of the first section (105) and the weft yarn.

(29) FIG. 2 partially depicts an element mount section (201) and a tape main body section (202) of a fastener tape (200) according to a second embodiment of the present invention. The tape main body section (202) is composed of a first section (205) with a mesh structure, which is close to the element mount section (201), and a second section (206) with higher weaving density, which is distant from the element mount section (201).

(30) In the first section (205), the warp yarns and the weft yarns are 210 dtex and have a twisting coefficient of 2.48 T/M; therefore, they are the yarns twisted by approximately 520 times per meter. In the first section (205), the framework of the mesh structure of the first section is formed by four warp yarns and four weft yarns as a set. As described above, in the present invention, two weft yarns are paralleled and counted as one yarn; thus, eight weft yarns constituting a set of weft yarns in FIG. 2 are counted as four yarns. Of the four warp yarns constituting a set of warp yarns, two warp yarns on the right and left sides are the combination of the 1/2 and 2/1 weave structures, and the central two warp yarns are the 4/4 weave structure. Of the four weft yarns constituting a set of weft yarns, two weft yarns on the top and bottom sides are the combination of the 1/2 and 2/1 weave structures, and the central two weft yarns are the 4/4 weave structure. An opening (207) of the first section is a rectangle with a horizontal length of 1.8 mm and a vertical length of 1 mm.

(31) In the element mount section (201) and the second section (206), the warp yarns and the weft yarns are the combination of the 1/1 and 2/2 weave structures, which plays a role of fixing the position of the mesh section. The element mount section (201) and the second section (206) employ the yarns with 330 dtex, which have been false twisted.

(32) FIG. 3 partially depicts an element mount section (301) and a tape main body section (302) of a fastener tape (300) according to a third embodiment of the present invention. The tape main body section (302) is composed of a first section (305) with a mesh structure, which is close to the element mount section (301), and a second section (306) with higher weaving density, which is distant from the element mount section (301).

(33) In the first section (305), the warp yarns and the weft yarns are 210 dtex and have a twisting coefficient of 2.0 T/M; therefore, they are the yarns twisted by approximately 420 times per meter. In the first section (305), the framework of the mesh structure of the first section is formed by three warp yarns and four weft yarns as a set. As described above, in the present invention, two weft yarns are counted as one yarn; thus, eight weft yarns constituting a set of weft yarns in FIG. 3 are counted as four yarns. Of the three warp yarns constituting a set of warp yarns, two warp yarns on the right and left sides are the combination of the 1/2 and 2/1 weave structures, and the central warp yarn is the 4/4 weave structure. Of the four weft yarns constituting a set of weft yarns, two weft yarns on the top and bottom sides are the combination of the 1/2 and 2/1 weave structures, and the central two weft yarns are the 3/3 weave structure. An opening (307) of the first section is a rectangle with a horizontal length of 2 mm and a vertical length of 1 mm.

(34) In the element mount section (301) and the second section (306), the warp yarns and the weft yarns are the combination of the 1/1 and 2/2 weave structures, which plays a role of fixing the position of the mesh section. The element mount section (301) and the second section (306) employ the warp yarns with 330 dtex, which have been false twisted.

(35) Here, FIG. 4 is a schematic cross-sectional view of a pair of fastener tapes (402) having elements (401) mounted thereto. A dotted line represents a cloth (403) of a body of a product to which the fastener tape is sewn. A symbol X represents the total width of the fastener tape, a symbol Y represents the width of the mesh section, and a symbol Z represents the width from the end of the fastener tape on the tape mount section side to the end of the mesh section.

(36) When the width Y of the mesh section (404) becomes too large, the fastener tape becomes too soft, in which case the cloth has low stiffness. Meanwhile, when the width Y becomes too small, the air permeability becomes impaired. In view of this, the width Y of the mesh section is preferably set to 10 to 50% of the width X of the entire fastener tape. When the width Z from the end of the fastener tape on the tape mount section side to the end of the mesh section becomes too large, the tape allows a smaller margin to sew up; meanwhile, when the width Z becomes too small, the air permeability is deteriorated. Therefore, the width Z is preferably 30 to 60% of the width X.

(37) <2. Slide Fastener>

(38) The mount of the elements to the element mount section of the fastener tape makes a fastener stringer, and the engagement of the right and left stringers completes a fastener chain. Then, the mount of a slider and, if necessary, a stopper to the slide fastener chain completes the slide fastener.

(39) In the present invention, there is no restriction to the type of the elements. For example, a single piece element as represented by a metal element and a plastic element molded on a tape by injection, a continuous element as represented by a coiled plastic element may be mentioned.

(40) The kind of the slide fastener is not particularly limited, and the present invention is applicable to any type of slide fasteners such as a non-separable product with a bottom end stop, a separable product having a separable bottom end stop, a reversely openable type, a head-to-head type, a back-to-back type, or a loop type.

(41) FIG. 5 depicts an example of the slide fastener having the fastener tape according to the present invention. Ina slide fastener (500) of FIG. 5, resin elements (502) are mounted to a fastener tape (501) according to the present invention having a mesh section (504) along a core string (509) of an element mount section (505) through injection molding. A slider (506) is inserted into a row of the elements (502). A top end stop (507) is provided at an upper end of the row of the resin elements (502) and a separable bottom end stop (508) is provided at a lower end thereof. In this embodiment, the width of the mesh section is approximately 20% of the width of the fastener tape. In this embodiment, the width from the end of the fastener tape on the tape mount section side to the end of the mesh section is approximately 53% of the width of the fastener tape. The slider (506) slides on the element mount section (505) and the mesh section (504) is preferably positioned outside the portion where the slider (506) slides.

(42) At one of or both the upper end and the lower end of the fastener tape, a reinforcement film is preferably pasted transversely across the mesh section such that the reinforcement film pinches a front side and a back side of the fastener tape. This provides the effect that the reinforcement film easily gets in close contact with the fastener tape, and moreover since the mesh section is not exposed at the upper end or the lower end, the strength at the end is improved. In this embodiment, a reinforcement film (510) is pasted at the upper end and the lower end.

(43) FIG. 6 depicts another example of the slide fastener having the fastener tape according to the present invention. In a fastener tape (601) according to the present invention having a mesh section (604) of a slide fastener (600) of FIG. 6, coil-like elements (602) are sewn to an element mount section (605) with a sewing yarn (603), and a slider (606) is inserted into a row of the elements (602). A top end stop (607) is provided at an upper end of the row of the coil-like elements (602) and a bottom end stop (608) is provided at a lower end thereof. In this embodiment, the width of the mesh section is approximately 15% of the width of the fastener tape. In this embodiment, the width from the end of the fastener tape on the tape mount section to the end of the mesh section is approximately 52% of the width of the fastener tape. The slider (606) slides on the element mount section (605) and the mesh section (604) is preferably positioned outside the portion where the slider (606) slides.

(44) The slide fastener of the present invention can be used as an opener/closer of an article by being sewn to the article. For example, the slide fastener can be applied to an opening of clothes, a pocket, a bag, shoes (for example, boots or other shoes), a tent, a mattress of a bed, or seats of a vehicle, for which the air permeability is required. For opening/closing the article, the slider is used for engaging or releasing the fastener elements. When the article does not need to be opened, the slider may be removed after closing the slide fastener.

(45) The embodiments of the present invention have been described so far; however, the present invention is not limited to those embodiments above and various modifications can be made within the scope of the present invention.
