DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
(17) Below, exemplary embodiments will be described in detail with reference to accompanying drawings so as to be readily understood by a person of ordinary skill in the art. The inventive concept may be embodied in various forms without being limited to the exemplary embodiments set forth herein. Descriptions of well-known parts are omitted for clarity, and like reference numerals refer to like elements throughout.
(18) An article according to a first exemplary embodiment is shown in
(19) According to the exemplary embodiment, the weft yarns comprise elastomeric yarns 105 and hard yarns 106. In this exemplary embodiment the elastomeric (or second) yarns 105 have a greater shrinkage ratio than the hard (or first) yarns 106. The elastomeric yarns 105 and hard yarns 106 are arranged in a predetermined arrangement comprising at least one hard yarn 106 alternately arranged with at least one elastomeric yarn 105. According to the exemplary embodiment illustrated in
(20) The weave of the fabric is such that the hard yarns form alternately arranged under portions 107 and over portions 108 with respect to the warp yarns 104. The under portions 107 are formed when the hard yarns pass along the backside of the warp yarns and defining loop portions 107a. The over portions are formed when the hard yarns pass along the front side of the warp yarns 104 and define connections portions 108a.
(21) In the exemplary embodiment, the fabric comprises hard weft yarns 106, for which the number of warp yarns 104 passed by each loop portion 107a is at least 6 and preferably within the range of 6 to 24; the number of warp yarns 104 passed by each loop portions 107a need not be the same for all loop portions 107a. It is not strictly necessary that every single loop portion 107a pass at least 6 warp yarns 104. So long as for each hard yarn 106 the average number of warp yarns 104 passed by each loop is at least 6, the number of warp yarns 104 passed by individual loop portions 107a can vary without deviating from the inventive concept, as would be known to one skilled in the art, provided the required loops are obtained on the back side of the fabric.
(22) While
(23) The elastomeric yarns form alternately arranged under portions 109 and over portions 110 with respect to said warp yarns 104 in the weave. These under portions 109 and over portions 110 form a weave with respect to the warp yarns 104 that is tighter than the weave formed by the hard yarns 106. While the weave pattern illustrated in
(24) According to exemplary embodiments, the loop portions 107a of the hard yarns are created such that they are in substantially less tension than under portions 109 and over portions 110 created by the elastomeric weft yarns 105. It can also be the case that the loop portions 107a are in at least one of equilibrium or compression.
(25) The loop portions 107a help to add to the knit-like appearance and behavior of the woven fabric. For example, loose loops 107a can hang loosely at the back of the fabric such that they are droopy. The droopy nature of the loop portions 107a gives the fabric a softer feel, much like that of a knitted fabric.
(26) Also, because knitted fabrics are created by connecting yarn loops together, the loop portions 107a give the back of the fabric the appearance of a knitted fabric. In addition, because of their length and droopiness, the loop portions 107a are able to cover a substantially larger portion of the back of the fabric than if they were tightly woven against the warp yarns. This allows the loop portions 107a to substantially hide the sometimes uncomfortable under portions 109. When the loop portions 107a are made from soft cotton yarns, as would often be the case, they provide a soft, comfortable backside to the fabric.
(27) An additional benefit of the droopy loop portions 107a is helping to prevent the warp yarns 104 from contacting the skin. This benefit is of particular importance to denim fabrics made from indigo dyed yarns. If these warps yarns 106 are indigo dyed and are allowed to come in contact with the wearer's skin, they can stain the skin when the wearer sweats.
(28) As seen in
(29) By using diagonal patterns, multiple benefits can be achieved. First, when the warp yarns 104 are indigo dyed, the use of a diagonal pattern can give the fabric the look of a classic denim weave, while maintaining all the benefits of the feel and behavior of a knitted fabric. The diagonal patterns also allow the fabric to stretch in the diagonal direction, further adding to the knit-like behavior of the fabric.
(30) In exemplary embodiments, the preferred warp density after weaving but before shrinking is between approximately 20 and 70 warp yarns per centimeter, inclusive. After treatment of the fabric and after three home washes, the preferred warp density is between approximately 25 and 80 warp yarns per centimeter, inclusive. Home washes are carried out at 60 C. followed by drying and the last wash and dry is followed by a conditioning a step for 8 hours; these tests are usual in the art and reference to ASTM D 3776/96 and to BS 63302A is made. It is even more preferred that the warp density after weaving but before shrinking be between approximately 25 and 60 warp yarns per centimeter, inclusive, and between approximately 30 and 65 warp yarns per centimeter after three home washes. Even more preferably, the warp density would be between approximately 30 and 50 warp yarns per centimeter, inclusive, after weaving but before shrinking, and between approximately 35 and 55 warp yarns per centimeter after three home washes. Generally, the warp and weft density measurements are made at 65% humidity, 5%, and 20 C., 2 C. Similar to the warp density, exemplary embodiments can also define weft densities. It is preferred that after weaving, but before shrinking, the weft density be between approximately 30 and 90 weft yarns per centimeter, inclusive. After three home washes it is preferred that the weft density be between approximately 35 and 95 wefts per centimeter, inclusive. In preferred embodiments, it is more preferred that after weaving, but before shrinking, the weft density be between approximately 40 and 80 wefts per centimeter, inclusive. After three home washings, it is more preferred that the weft density be between approximately 45 and 85 wefts per centimeter, inclusive. It is even more preferred that after weaving but before shrinking, the weft density be between 50 and 70 wefts per centimeter, inclusive, and between approximately 55 and 75 wefts per centimeter, inclusive, after three home washes.
(31) The selection of the warp and weft densities not only adds to the knit-like behavior of the fabric, but it also allows, in conjunction with the selection of appropriate yarns, for the creation of fabrics having different weights. For example, the weight can be chosen to be similar to that of a t-shirt, or alternatively, similar to that of sweatpants. In exemplary embodiments, the ratio of the average number of warp yarns passed by the loop portions to a warp density is between approximately 0.2 and 0.7, inclusive.
(32) In other exemplary embodiments, the ratio of the average number of warp yarns passed by the loop portions to the average number of warp yarns passed by the connection portions is between approximately 6 and 24, inclusive.
(33) Another aspect of exemplary embodiments is the thickness of the yarns used for the warp and weft yarns. Because the elastomeric (second) yarns will often be synthetic, they will be described herein using denier (den.), while the warp yarns and hard (first) weft yarns will be described using English cotton yarn number (Ne). Not withstanding the numbering system used to describe the yarns, a person of ordinary skill in the art will know how to convert from one system to the other, and would understand that the numbering system used in no way limits the properties and compositions of the yarns used.
(34) Though not drawn to scale, it is illustrated in
(35) By selecting the relative thicknesses of the yarns within the values of the inventive concept multiple benefits are achieved. For example, when the thickness of the hard weft yarns 106 is larger than that of the elastomeric weft yarns 105, the thicker loop portions 107a are better able to hide the under portions 109 from being seen and felt at the back of the fabric. The selection of correct yarn thicknesses also add to the knit-like feel and weight of the fabric.
(36)
(37) In
(38) In exemplary embodiments the second weave 203 substantially prevents the warp yarns 104 passed over by the elastomeric fibers 105 of the first weave 202 from being felt or seen from the back side 103 of the fabric 101.
(39)
(40) Functional block 402 is a step in which hard weft yarns are provided. Similar to step 401, this step can include determining all the aspects of the hard weft yarns known to those skilled in the art, including but not limited to: the thickness of the yarns, shrinkage ratio, elasticity, color, weft density, etc., the shrinkage ratio being that the elastomeric yarns are capable of greater shrinkage than the hard yarns. Functional block 403 represents a similar step with regards to the elastomeric weft yarns. In this step, all aspects of the elastomeric weft yarns can be selected.
(41) Functional block 404 represents the step of determining a weave pattern. In this step, any weave pattern known to those skilled in the art can be selected, so long as at least one hard yarn is alternately arranged with at least one elastomeric yarn; ensuring the hard yarns pass alternately along the back side of the warp yarns in a predetermined number of warp yarns for each pass to form a series of over portions and under portions, and along the front side of the warp yarns a predetermined number of warp yarns for each pass to form hard over portions; the average number of warp yarns passed by each under portion is at least six; and the elastomeric yarns pass alternately along the back side of the warp yarns a predetermined number of warp yarns for each pass to form a series of elastomeric under portions, and along the front side of the warp yarns a predetermined number of warp yarns for each pass to form a series of elastomeric over portions.
(42) Functional block 405 represents weaving the warp and weft yarns according to the selected weave pattern.
(43) Functional block 406 represents the step of shrinking the fabric after weaving. During this shrinking the elastomeric yarns will shrink more than the hard yarns causing the under portions to become loop portions. Shrinking naturally occurs as soon as the fabric is removed from the weaving loom and the yarns are no longer under tension; further shrinking is carried out by wetting the fabric, during the finishing processes.
(44) In exemplary embodiments, the loops portions are in substantially less tension than the over portions and under portions formed by the elastomeric yarns. In other exemplary embodiments the loops portions are in at least one of equilibrium and compression.
(45) Other exemplary embodiments can add additional steps to the process of creating the fabric. These steps can include applying weathering effects to the finished fabric such as bleaching, hand scraping, sand blasting, stone washing and others known to those skilled in the art. These steps can include brushing either one of the front or back side of the fabric. The process can also include printing letters or graphics onto the fabric, or embroidering patterns and logos onto the fabric. The fabric can even be ripped and torn to meet the demands of current fashion trends. The process can also include tailoring the fabric into garments, or other steps known to those skilled in the art.
(46) What follows next are very specific examples of exemplary embodiments according to the inventive concept. The inventive concept is capable of other and different embodiments without deviating from the scope and spirit of the inventive concept. The examples should be considered illustrative in nature and not as restrictive. They are illustrated with reference to the weave reports of
Example 1
(47) The result of this exemplary embodiment is a knitted fabric having the weight and feel of a knitted t-shirt, but doing so with indigo dyed yarns which will allow for the application of abrasion effects previously only available at great cost. The warp yarns, weft yarns, warp density, weft density and loom set-up were chosen according to the values in Table 1. These selections gave the resulting fabric a weight of approximately 5-7 oz/sqyd (170-240 g/cm.sup.2). The weave pattern was selected according to the weave report depicted in

(49) After weaving, the fabric was wetted and stretched in the length (warp) direction. When this happens, the fabric shrinks in the width (weft) direction, the Lycra (elastane) yarn pulling the warn yarns together. Because the cotton weft yarns contain no elastane, they do not shrink as much as the Lycra yarns, and the cotton yarn floats on the back of the fabric formed long loops which cover most of the back side of the fabric. After shrinking, the fabric was heat set to reduce shrinking in further garment washings.
(50) The resulting fabric had the weight and feel of a knitted fabric, including the much softer feel generally associated with knitted fabrics. At the same time, the indigo warp yarns gave the warp side fabric the look and qualities of a denim fabric, such as denim's ability to take on finishing effects, such as abrasion effects. The back side of the fabric was white in color due to the un-dyed weft yarns, and was extremely soft due to the long loops created thereon. A person wearing a garment made from the fabric is prevented from feeling the uncomfortable polyester weft yarns by the long loops that dominate the back side of the fabric. The long loops also prevent the indigo from coming into contact with the skin of a person wearing the garment, preventing the indigo dye from running if the person sweats.
(51) Due at least in part to the selection of the weave and elastomeric weft yarns, the resulting fabric had very high elastic properties. These properties included the ability to stretch in all directions, not just the weft direction.
