Problems solved by technology

[0003] At present, although the elastic recovery rate and elongation rate of the existing elastic fabrics on the market are not bad, they are generally polyester fabrics or NY fabrics containing spandex, especially fabrics containing spandex. On the appearance, there are often spots where the spandex is exposed, which greatly hinders the performance of the product.

Abstract

The invention discloses a production process of nylon high-elasticity fabric and a production process of protofilaments of the nylon high-elasticity fabric. The warps of the fabric use 5D-70D nylon high-elasticity yarn or the DTY or FDY of 7D-70D NY6 or NY66, the wefts of the fabric use 5D-70D nylon high-elasticity yarn, the weave of the fabric adopts plain weave, plaid or 2 / 1 or 2 / 2 twill weave,the warp-wise elastic extension of the fabric is 15-25%, the weft-wise elastic extension of the fabric is 15-35%, the elastic recovery rate of the fabric is 60-90%, and the warp-wise and weft-wise tear strength reaches 5-20N. The fabric produced by the production process can keep good elastic extension and elastic recovery rate, is comfortable in touch, has a good clothing function, can relieve human body constraint of garments and is widely applicable to textile and garment enterprises and capable of increasing product added value and increasing product market competitiveness, the garments made by the fabric are comfortable and light to wear, and people who wear the garments can move easily.

Description

technical field [0001] The invention relates to a manufacturing process of nylon high-elastic fabric and a preparation process of raw silk thereof. The fabric has excellent rebound performance, and the yarn has good elasticity, delicate hand feeling, and is not easy to wrinkle and deform, so it can be widely used in the textile and garment industry. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for clothing fabrics, especially casual fabrics. The light, thin and soft textile fabrics with good elasticity and elongation and strong recovery performance are favored by consumers. Judging from the current market, high-quality elastic fabrics have become the first choice of consumers, and there is a huge market demand. However, most elastic products on the market are products containing spandex, and non-spandex elastics are rare, especially nylon non-spandex materials. It can be seen that st...
