Elastic yarn, and manufacturing method and fabric thereof

Abstract

The invention belongs to the technical field of textile engineering, and particularly relates to a manufacturing method of an elastic yarn. According to the manufacturing method, an elastic core fiberingeniously cooperates with drafting multiple, the elastic yarn has the advantages of high elasticity and low shrinkage, the shrinkage rate is 35% or below while the elongation is 40% or above, namely, the standards of high elasticity and low shrinkage are satisfied, and the defects of high shrinkage, low drafting and low shrinkage of the conventional high-elastic yarn are overcome. The elastic yarn is not limited to use as a weft yarn or a warp yarn; a fabric woven with the elastic yarn has a high elastic recovery rate, the latitudinal elastic recovery rate is between 55% and 85%, the latitudinal elastic elongation is 40% or above, the pilling level is 3.5-5, and the wrinkle recovery performance level is 4-5.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to an elastic yarn, a manufacturing method thereof and a fabric. Background technique [0002] Stretch denim fabrics on the market usually use ordinary cotton core-spun spandex yarn, which has the aesthetic feeling of shaping and compacting, and is favored by young women. Problems such as drumming and bagging will affect the shape effect of the fabric. [0003] At present, high-elastic fabrics produced at home and abroad refer to fabrics with a weft elongation of more than 40%. Generally, the finishing methods of high-elastic fabrics include: singeing, desizing, the first pre-shrinking treatment, the second pre-shrinking treatment, and the second pre-shrinking treatment. shrink processing. However, after finishing by the above method, the shrinkage rate of the high elastic fabric is between 15% and 20%. High shrinkage has the following adverse effects on the productio...

AI Technical Summary

Problems solved by technology

High shrinkage has the following adverse effects on the production of high-elastic garments and the washing of garments: First, there is a curling problem in the cutting process of high-elastic fabrics; It is easy to wrinkle and affect the appearance; the third is that the high-elastic fabric slips and elastics at the seam of the garment, resulting in unqualified products; the fourth is that the size of the high-elastic fabric is unstable after the garment is washed

[0004] In order to reduce the shrinkage rate of high-elastic fabrics, the method adopted in the existing technology is: to design a larger reed width to increase the rebound space of spandex yarn, which brings problems of large yarn consumption, high production cost, and consumes more Steam, water, electricity, and labor intensity of workers, but the pre-shrinking fabric width is still difficult to shrink; another way is to increase the number of pre-shrinking times, using two or even three times the whole process of pre-shrinking, but at the same time it brings a lot of pressure to continuous production. The shrinkage rate is still as high as -10~-18%.
