Technical Field
[0001] This utility model relates to the field of textile technology, specifically to an elastic interwoven twill fabric. Background Technology
[0002] As people's awareness of environmental protection and health continues to increase, and their living standards improve, their demands for textiles are also rising. While pursuing high-end, comfortable, green, and environmentally friendly clothing products, they also desire good quality at reasonable prices. Twill fabric, with its twill weave, has a distinct diagonal pattern on the surface, giving it a layered and three-dimensional feel. It is soft, smooth to the touch, and comfortable to wear. The characteristics of twill make it widely used in garment manufacturing; it can be used to make shirts, jackets, trousers, dresses, etc., making it a superior choice for clothing production. While silk twill has a certain degree of wrinkle resistance due to its tight structure, its wrinkle resistance and abrasion resistance are not ideal, and its high price often puts it out of reach for the average consumer. To reduce the cost of silk twill fabric, fabrics have also been developed on the market by interweaving mulberry silk with rayon or mulberry silk with nylon. Although these fabrics have reduced the cost, they are not ideal in terms of functionality and comfort. For example, fabrics interweaving mulberry silk with rayon have poor wrinkle resistance and abrasion resistance, while fabrics interweaving mulberry silk with nylon have poor breathability.
[0003] The key technical challenge is to find a way to combine silkworm silk with fibers such as rayon, nylon, and spandex to reduce the cost of silk fabrics while improving their wrinkle resistance, abrasion resistance, breathability, and wearing comfort. Utility Model Content
[0004] To address the above issues, this utility model provides an elastic interwoven twill fabric. The product combines the excellent properties of four materials. While maintaining the high-end style of mulberry silk fabric, it has a soft and comfortable feel and good elasticity. Compared with mulberry silk / rayon interwoven fabrics and mulberry silk / nylon interwoven fabrics, this type of product has been greatly improved in terms of overall wrinkle resistance, abrasion resistance, moisture absorption and breathability, and wearing comfort, resulting in a significant improvement in performance.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A type of elastic interwoven twill fabric is woven from one type of warp yarn and two types of weft yarns, A and B. The warp yarn is made of two 20 / 22D mulberry silks twisted together in the S direction with 400 twists per meter. The A weft yarn is made of one 75D rayon as the outer yarn and 40D spandex as the core yarn, wrapped with 1000 twists per meter in the S direction. The B weft yarn is made of 1 / 70D 48F nylon yarn.
[0007] The warp yarns have 10 cycles, and the weft yarns have 10 cycles. The weft yarns are fed in a pattern of one weft yarn per shuttle (A weft, B weft), and are woven with the warp yarns using a 4-up-2-down-3-up-1-down alternating left-hand twill weave structure, creating a left-facing twill pattern on the fabric surface. The points where the warp yarns are on top are the warp weave points, and those on the bottom are the weft weave points. The warp weave points are as follows:
[0008] The weave point of the first warp yarn is: four up, two down, three up, one down;
[0009] The weave point of the second warp yarn is: three up, two down, three up, one down, one up;
[0010] The weave point of the third warp yarn is: two up, two down, three up, one down, two up;
[0011] The weave point of the fourth warp yarn is: 1 up, 2 down, 3 up, 1 down, 3 up;
[0012] The weave point of the fifth warp yarn is: 2 down, 3 up, 1 down, 4 up;
[0013] The weave point of the VIth warp yarn is: one down, three up, one down, four up, one down;
[0014] The weave point of the VIIth warp yarn is: 3 knit, 1 nit, 4 knit, 2 nit;
[0015] The weave point of the eighth warp yarn is: 2 up, 1 down; 4 up, 2 down, 1 up;
[0016] The weave point of the IXth warp yarn is: 1 up, 1 down; 4 up, 2 down, 2 up.
[0017] The weave point of the 10th warp yarn is: 1st down, 4th up, 2nd down, 3rd up.
[0018] Preferably, the finished elastic interwoven twill fabric has a warp density of 117.5 threads / cm and a weft density of 43.5 threads / cm.
[0019] The advantages of this utility model are as follows: 1. The warp yarn of the product is 2 / 20 / 22D 400T / m / S mulberry silk, and the weft yarn is (1 / 75D rayon + 40D spandex) 1000BC / S and 1 / 70D high-elasticity nylon. It is woven with a modified twill weave. The product combines the excellent properties of four materials. While maintaining the high-end style of mulberry silk fabric, the product is soft and comfortable to the touch and has good elasticity. Compared with mulberry silk / rayon interwoven fabric and mulberry silk / nylon interwoven fabric, this type of product has been greatly improved in terms of overall wrinkle resistance, abrasion resistance, moisture absorption and breathability, and wearing comfort, and its performance has been greatly improved.
[0020] 2. Wrap rayon and spandex together by optimizing the material ratio of rayon and spandex, the draw ratio of spandex, the degree of wrapping, and the shaping process of rayon / spandex wrapping yarn, so that the rayon / spandex wrapping yarn has good elasticity and forming quality.
[0021] 3. Optimize the ratio of four materials in the fabric: mulberry silk, rayon, nylon, and spandex. Use rayon / spandex wrapped yarn and high-elasticity nylon as weft yarn, and shuttle them in a 1:1 ratio to make the fabric have excellent elasticity, wrinkle resistance, abrasion resistance and moisture absorption and breathability.
