Problems solved by technology

However, this invention needs to carry out the core-spun process first, with spandex as the core, to prepare the deep-dyed polyester fiber-coated spandex core-spun yarn through the core-spun process, and the procedure is relatively complicated
[0005] At present, there is a lack of a double-sided fabric that has a simple preparation method and gives full play to the advantages of spandex. Polyester and nylon alone are stretched looser, have a small modulus, and insufficient recovery force. After stretching, the recovery of the cloth surface is poor, and spandex alone has poor moisture absorption. ; Not resistant to oxidation; while spandex, polyester, and nylon are mixed to prepare double-sided fabrics, the process is complicated, and it is difficult to realize

Embodiment 1-4

[0053] Weaving raw materials and quantity:

[0054] PA6 40D / 34F DTY or polyester 24pcs

[0055] PU 40D 48 pcs

[0056] PU 20D 24 pcs.

[0057] The raw material composition of embodiment 1-4 is as shown in table 1:

[0058] Table 1.

[0059]

[0060]"PA6 40D / 34F SD DTY" means semi-dull stretch textured nylon 6 with a thickness of 40D and a hole number of 34F.

[0061] Embodiment 1-4 is all prepared according to the following method:

[0062] The double-sided circular knitting machine is used for weaving, and the inner diameter of the two conveying discs of the double-sided circular knitting machine is adjusted, and the yarn storage device is driven by the conveying belt to provide the corresponding incoming line speed, and the corresponding incoming yarn is introduced into each loop. Long, and keep the tension of each thread of the same raw material consistent, the raw yarn is introduced into the knitting loop area through the yarn feeder to be woven into a loop and for...

Abstract

The invention relates to the technical field of textiles, in particular to a chemical fiber elastic double-sided cloth with one side being all spandex and a preparation method thereof. One side of the double-sided cloth is all spandex, and the other side is all nylon or polyester. The raw materials are composed of: : PA6 40D / 34F DTY or polyester 49‑53%, PU 40D 38‑42%, PU 20D 7‑11%. The preparation process of the invention is simple, the advantages of spandex and nylon / polyester are fully utilized, the stretch recovery effect is good, the skin-adhesive performance is good, the washing fastness and color fastness are good, it is not easy to slip after contacting the skin, and the anti-slip effect is good.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a chemical fiber elastic double-sided fabric with one side being all spandex and a preparation method thereof. Background technique [0002] With the development of knitting technology and the change of people's consumption concept, knitted fabrics are developing in the direction of outerwear and fashion. Comfortable and environmentally friendly knitted outerwear is more and more favored by consumers. When weaving knitted fabrics, the front and back can form double-sided fabrics with different styles on the front and back by using different gauge equipment and different types of yarns to weave different weave structures. Common weft-knitted double-sided fabrics on the market are generally woven by double-needle bed double-sided knitting circular machines. The two sides of the fabric are nylon or polyester, and the middle structure is connected by nylon or polyester or spandex, o...
