Patent Application
20190093261
The disclosed technology relates generally to woven fabrics, and, more particularly, some embodiments relate to woven fabrics having stretch weft yarns.
Attempts have been made to produce a fabric that looks, feels, and performs like a knitted fabric, but is created through weaving. One such example is shown in U.S. Patent Application Publication No. 2011/0212659 to Hamit Yenici et al. Another such example is shown in U.S. Patent Application Publication No. 2013/0048140 to Hamit Yenici et al.
Both of these U.S. patent application publications to H. Yenici teach a fabric with wefts that include hard yarns and elastomeric yarns in a predetermined arrangement. At least one hard yarn is alternately arranged with at least one elastomeric yarn, the elastomeric yarns having a greater shrinkage ratio than that of the hard yarns. The hard yarns form under portions and over portions with respect to the warp yarns. The under portions are formed when the hard yarns pass along the back side of the warp yarns, defining loop portions. The over portions are formed when the hard yarns pass along the front side of the warps, defining connection portions. The elastomeric yarns form under portions and over portions with respect to the warp yarns in a weave that is tighter than the weave of the hard yarns.
Such fabrics have been found to have less-than-optimal performance respecting their elasticity and/or appearance, among other things. There is thus a need for a better-performing woven fabric that performs like a knitted fabric.
Various embodiments of the present disclosure include a woven fabric comprising a plurality of warp yarns and a plurality of weft yarns woven through the plurality of warp yarns. A first set of the plurality of weft yarns are woven through the plurality of warp yarns in a 6×1 pattern, and a second set of the plurality of weft yarns are woven through the plurality of warp yarns in a 13×1 pattern.
In an embodiment, each of the plurality of weft yarns is in either the first set or the second set.
In an embodiment, the plurality of weft yarns in the first set and the second set are arranged in a repeating pattern.
In an embodiment, the repeating pattern comprises two weft yarns woven in the 6×1 pattern followed by one weft yarn woven in the 13×1 pattern.
In an embodiment, the plurality of warp yarns comprise Ne 16/1 to Ne 32/1 ring-spun, 100-percent cotton, indigo-dyed yarns, and the plurality of weft yarns comprise 19/1 to 32/1 TR blended plus 40 Denier lycra spun yarn.
In an embodiment, the plurality of warp yarns have a warp yarn density of approximately 90 ends per inch after weaving, and the plurality of warp yarns have a warp yarn density between approximately 110 ends per inch to approximately 170 ends per inch after shrinking.
In an embodiment, the plurality of weft yarns have a weft yarn density of approximately 90 picks per inch after weaving, and the plurality of weft yarns have a weft yarn density between approximately 96 ends per inch to approximately 114 ends per inch after shrinking.

In an embodiment, the plurality of warp yarns have a thickness between 16S to 32S, and the plurality of weft yarns have a thickness between 19S to 32S.
In an embodiment, the plurality of weft yarns have the same size of yarn count under the same tension, and perform with the same shrinkage ratio.
Various embodiments of the present disclosure include a method of weaving a woven fabric comprising weaving a first plurality of weft yarns through a plurality of warp yarns in a 6×1 pattern and weaving a second plurality of weft yarns through the plurality of warp yarns in a 13×1 pattern. The first plurality of weft yarns and the second plurality of weft yarns are arranged in a repeating pattern.
In an embodiment, the repeating pattern comprises two weft yarns woven in the 6×1 pattern followed by one weft yarn woven in the 13×1 pattern.
In an embodiment, the plurality of warp yarns comprise Ne 16/1 to Ne 32/1 ring-spun, 100-percent cotton, indigo-dyed yarns, and the first and second pluralities of weft yarns comprise 19/1 to 32/1 TR blended plus 40 Denier lycra spun yarn.
In an embodiment, the plurality of warp yarns have a warp yarn density of approximately 90 ends per inch after weaving, and the plurality of warp yarns have a warp yarn density between approximately 110 ends per inch to approximately 170 ends per inch after shrinking.
In an embodiment, the first and second pluralities of weft yarns have a weft yarn density of approximately 90 picks per inch after weaving, and the first and second pluralities of weft yarns have a weft yarn density between approximately 96 ends per inch to approximately 114 ends per inch after shrinking.
In an embodiment, the plurality of warp yarns have a thickness between 16S to 32S, and the first and second pluralities of weft yarns have a thickness between 19S to 32S.
In an embodiment, the first and second pluralities of weft yarns have the same size of yarn count under the same tension and perform with the same shrinkage ratio.
In an embodiment, the first and second pluralities of weft yarns are woven through the plurality of warp yarns using a dobby-type weaving loom having a weft selection system.
In an embodiment, the method further comprises wetting the woven fabric and stretching the woven fabric in a warp direction to allow the woven fabric to shrink in a weft direction.
In an embodiment, the method further comprises heat setting the woven fabric.
It should be appreciated that many other features, applications, embodiments, and/or variations of the disclosed technology will be apparent from the accompanying drawings and from the following detailed description. Additional and/or alternative implementations of the structures, systems, non-transitory computer readable media, and methods described herein can be employed without departing from the principles of the disclosed technology.
Embodiments of the technology disclosed herein are directed toward woven fabrics and methods for making woven fabrics. More particularly, the various embodiments of the technology disclosed herein relate to woven fabrics having stretch weft yarns.
In the weaving pattern, the weft yarns are woven in front of and in back of the warp yarns to create the woven fabric. For example, weft yarn 1 is woven in back of warp yarns 1-6 and in front of warp yarn 7, and then woven in back of warp yarns 8-13, and in front of warp yarn 14, and so forth. In certain embodiments, all of the weft yarns have the same shrinkage ratio and the same size of yarn count.
As shown in the figures, the repeat intersection points on the weft yarns are either 6×1 or 13×1. In other words, some of the weft yarns have 6 warp yarns across on the back side of the fabric, followed by 1 warp yarn across on the front side of the fabric (e.g., warp yarn 1, warp yarn 2, warp yarn 4, warp yarn 5, etc.). The other weft yarns have 13 warp yarns across on the back side of the fabric, followed by 1 warp yarn across on the front side of the fabric (e.g., warp yarn 3, warp yarn 6, warp yarn 9, etc.).
As shown in the figures, weft yarns 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17, 19, 20, 22, 23, 25, 26, 28 and 29 are woven in the 6×1 pattern. Weft yarns 3, 6, 9, 12, 15, 18, 21, 24, 27 and 30 are woven in the 13×1 pattern. In the embodiment shown in
In one embodiment, the warp yarns are Ne 16/1 to Ne 32/1 ring-spun, 100-percent cotton, indigo-dyed yarns. The stretch weft yarns are 19/1 to 32/1 TR blended plus 40 Denier lycra spun yarn. The warp-yarn density is approximately 90 ends per inch after weaving and approximately 110 ends per inch to approximately 170 ends per inch after shrinking. The weft-yarn density is approximately 90 picks per inch after weaving and approximately 96 ends per inch to approximately 114 ends per inch after shrinking. The fabric weight is 7 ounces to 9 ounces per square yard. The thickness range of the warp yarns is 16S to 32S. The thickness range of the weft yarns is 19S to 32S. All of the weft yarns use the same size of yarn count under the same tension and perform with the same shrinkage ratio. A dobby-type weaving loom having a weft selection system can be used for the weaving. After weaving, the fabric may be wetted and stretched in the warp direction to allow the fabric to shrink in the weft direction, with the stretch weft yarns pulling the warp yarns closer together. After shrinking, the fabric may be heat set to reduce shrinking in further washings.
