Abstract
Description
A method for improving the strength of full-stretch knitting and the fabric thereof Technical Field
[0001] This invention relates to the field of woven fabric technology, and in particular to a full-stretch knitting method and fabric for improving strength. Background Technology
[0002] The existing woven plain weave method uses alternating warp and weft yarns for weaving. The upper mesh fabric woven using this method has a tight gap between the warp and weft yarns, small pores, and fixed pores that cannot be adjusted, resulting in an inability to adjust the breathability. This cannot meet the requirements of running shoes, sports shoes, and other specialized shoes for good breathability, varying breathability levels, and high durability. Therefore, it is necessary to develop an upper fabric that is breathable, allows for adjustable breathability, and is lightweight.

[0035] Referring to Figure 1, which is a schematic diagram of the structure of multiple patterns woven together in some embodiments of the present invention.
[0036] According to some embodiments of the present invention, the present invention provides a full twisted knitting method for improving strength, comprising a first warp group 11 including at least two ground warps 111, a second warp group 12 including at least one twisted warp 121, and a weft group 2 including at least two weft yarns; the first warp group 11 and the weft group 2 are woven together to form a plain weave 3, and the two adjacent ground warps 111 and the weft yarns are interwoven in a staggered manner, the second warp group 12 moves along the direction of the first warp group 11 and twists and wraps around the first warp group 11, and the twisted warp 121 is located below the weft group 2.
[0037] Preferably, the weft yarn group 2 is made of spandex-covered yarn or polyester elastic yarn, and at least one of the second warp yarn groups 12 is a monofilament yarn, polyester multifilament yarn, or nylon multifilament yarn.
[0038] Referring to Figures 2 and 3, Figure 2 is a schematic diagram of the specific structure of the twisted knitting in some embodiments of the present invention; Figure 3 is a schematic diagram of the structure between the first warp group, the second warp group and the weft group in some embodiments of the present invention.
[0039] According to some embodiments of the present invention, optionally, the weaving method sets up an array of weft yarn groups 2, with a breathable gap 4 between each two weft yarn groups 2. The breathable gap 4 is formed by the twisting warp 121 rotating and twisting the ground warp 111 to bundle the two weft yarn groups 2 together.
[0040] The specific weaving path of the twisted warp 121 is as follows: when it is woven side by side with the first warp group 11 to the weft group 2, it falls below the weft group 2, passes through the weft group 2 to the ventilation gap 4, and then the twisted warp 121 flips up to the upper side of the first warp group 11. While it is wrapped with the first warp group 11 to generate the twist point 6, the twisted warp 121 falls to the other side of the first warp group 11, and then repeats the step of falling below the weft group 2.
[0041] In this weaving method, an array of first warp yarn groups 11 and a corresponding number of second warp yarn groups 12 are set. Each first warp yarn group 11 and each second warp yarn group 12 are twisted and wound to form a bundle of warp yarn 1. When several bundles of warp yarn 1 are interwoven with the weft yarn group 2 having the air gap 4, a perforated structure 5 is formed.

[0043] The number of weft yarns is at least two, and the weft yarn group 2 is divided into a first weft yarn 21 and a second weft yarn 22. The first weft yarn 21 and the second weft yarn 22 are woven in parallel with the warp yarn 1 for a number of sequences and then separated. The first weft yarn 21 moves up and is woven with the previous weft yarn group for a number of sequences. The second weft yarn 22 moves down and is woven with the next weft yarn group for a number of sequences. Finally, the first weft yarn 21 and the second weft yarn 22 are merged again and woven in parallel for a number of sequences.
[0044] The number of weft yarns is at least three, and the weft yarn group 2 is divided into a first weft yarn 21, a second weft yarn 22, and a third weft yarn 23. The first weft yarn 21, the second weft yarn 22, and the third weft yarn 23 are woven in parallel for a number of times and then separated. The second weft yarn 22 is woven horizontally. The first weft yarn 21 moves up and weaves with the previous group of the same weft yarn group. The second weft yarn 22 moves down and weaves with the next group of the same weft yarn group. Finally, the first weft yarn 21 and the second weft yarn 22 are merged again and woven in parallel for a number of times.
[0045] This embodiment also provides a fully twisted knitted fabric with improved strength, including a first warp group 11 having at least two ground warps 111, a second warp group 12 having at least one twisted warp 121, and a weft group 2 having at least two weft yarns; the second warp group 12 and the weft group 2 are intertwined to form a plain weave 3, and the two adjacent ground warps 111 and the weft yarns are interwoven with each other in a staggered manner, the second warp group 12 moves along the direction of the first warp group 11 and twists and wraps around the first warp group 11, and the twisted warp 121 is located below the weft group 2.
[0046] The woven fabric has an array of weft yarn groups 2, and a breathable gap 4 is provided between each two weft yarn groups 2. The breathable gap 4 is formed by the twisting warp 121 twisting the ground warp 111 to bundle the two weft yarn groups 2 together.
[0047] The woven fabric is provided with an array of first warp yarn groups 11 and a corresponding number of second warp yarn groups 12. Each array of first warp yarn groups 11 and each array of second warp yarn groups 12 are twisted and wound to form a bundle of warp yarn 1. When several bundles of warp yarn 1 are interwoven with the weft yarn group 2 having the air gap 4, a perforated structure 5 is formed.
[0048] According to some embodiments of the present invention, optionally, the above-described weaving method exhibits a variety of weaving patterns, and the weave made by the weaving method can also have a variety of patterns. The full-twist woven fabric is obtained by any combination of the above-described patterns, and any two full-twist patterns can be woven together as a whole.
