Double-core-spun cellulose fiber yarn and production process thereof

Abstract

The invention relates to the technical field of textile fibers, in particular to a double-core-spun cellulose fiber yarn and a production process thereof. The production process comprises the following steps: S1, preferably selecting synthetic filaments with the strength and elasticity of 1N-5N in fiber raw materials, and wrapping the core silks with cotton, wool and viscose fibers; S2, operatingaccording to specified spinning main points; S3, selecting double-core-sun-yarn core silks; S4, determining the silk content and selecting a process; S5, warp yarn preparation: cheese spinning, warping, sizing and drawing-in; and S6, weft yarn preparation: cheese spinning, reeling and skeining, vinylon-dissolving, cleaning, drying and spooling, and summarizing. By arrangement and experiments, theproblems that the shrinkage rate in the weft direction of a high-elasticity fabric is high, processing requirements of the following process cannot be met fully, the elastic extension rate in the weftdirection is low, and a person has bound feeling when wearing clothes made of the fabric, an elastic fabric is poor in rebound resilience and fatigue resistance, and the elastic fabric has problems of elasticity losing and thread breakage when the clothes are washed and worn for a long time are solved.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to a double-cored cellulose fiber yarn and a production process thereof. Background technique [0002] Stretch denim fabric embodies the wearer's physical beauty and fashion dynamics with its flexible, comfortable fit, compact shape, and occupies a large proportion in the existing denim fabric product pattern, especially in the field of denim women's clothing fabrics. Unfathomable" situation. The elasticity of elastic fabric depends on the application of spandex yarn. Since spandex was introduced into my country in the 1990s, its application in the field of textile fibers has become more and more extensive. Especially in recent years, spandex elastic fabric has become popular all over the world. It has been widely used. Stretch denim fabrics are constantly changing from the initial weft stretch to warp and weft double stretch, from micro-stretch to mid-stretch, and from comfo...

Problems solved by technology

[0003] In the prior art, high-elastic fabrics have a large weft shrinkage rate, which cannot fully meet the processing requirements of subsequent processes; the weft elastic elongation rate is small, and there is a sense of restraint when wearing; elastic fabrics have poor resilience and fatigue resistance; During washing and long-term wearing of clothing, it is easy to lose bullets and break wires
