Cotton/chinlon FDY high count yarn for warp knitting and spinning method thereof

Abstract

The invention provides a cotton / chinlon FDY high count yarn capable of being used for warp knitting. The cotton / chinlon FDY high count yarn is formed by 35%-50% of long stapled cotton and 50%-65% of chinlon and is spun in an embedded compact spinning mode. The spinning method includes the steps that (a) two long stapled cotton rough yarns are arranged in the middle, two chinlon FDY filament yarns are distributed on the two sides of the two long stapled cotton rough yarns, the four yarns serve as two groups, each group comprises one long stapled cotton rough yarn and one FDY filament yarn, and when the four yarns pass through a drafting roller front jaw horizontal line, downward air negative pressure is added below a twisting triangular space plane in the normal direction; (b) twisting is conducted on the two groups of the yarns in a first twisting triangular space and a second twisting triangular space; (c) twisted semi-finished yarns enter a third twisting triangular space to be twisted to obtain the finished cotton / chinlon FDY high count yarn. The strength of the cotton / chinlon FDY high count yarn can meet the warp knitting requirement, and the surface of a spun finished product has obvious cotton feeling.

Description

technical field [0001] The invention relates to a high-count cotton / nylon FDY yarn for warp knitting, which belongs to the field of textile processing. Background technique [0002] There are many kinds of warp knitted fabrics, which are widely used in clothing, decoration and other industrial fields. With the continuous development of fiber technology and mechanical technology, the grade of warp knitting products has been continuously improved, and the products are developing in the direction of diversification, high-grade and functionalization. At present, the raw materials for warp knitting at home and abroad are generally three major chemical fibers: polyester, nylon and spandex. With the continuous strengthening of the concept of returning to nature, natural fibers are favored by people. Among them, people have a soft spot for cotton fibers. Cotton fiber has good hygroscopicity and air permeability, soft and comfortable to wear, good warmth retention, and good wearin...

AI Technical Summary

Problems solved by technology

Cotton fiber has good hygroscopicity and air permeability, soft and comfortable to wear, good warmth retention, and good wearing performance. However, the strength of cotton yarn cannot meet the requirements of warp knitting yarn, and yarn breakage and weaving fly are caused by entanglement of hair. and other problems, cotton yarn is often only used for warp knitting in rough gauges, and most of them are mesh products

In the prior art, there is still a lack of warp knitted fabrics with high strength and obvious cotton feeling
