Spinning process of cashmere blended yarn

Abstract

An embodiment of the invention discloses a spinning process of a cashmere blended yarn. The process comprises the steps of material selection, wherein the following raw materials in percentage by massare selected: 50-60% of cashmere in the blended yarn, 20-30% of synthetic fibers in the blended yarn and 15-20% of viscose fibers in the blended yarn; cotton cleaning; cotton carding, wherein combednoil fiber rolls are treated with a cotton carding machine to obtain cotton fiber slivers; drawing, wherein drawing is performed for three times; and spinning, wherein a full-automatic rotor spinningmachine is adopted, the cotton slivers obtained by the drawing process are fed into the rotor spinning machine, and air spinning is performed to obtain a cotton yarn product. Compared with the prior art, the spinning process has the following beneficial effects: the spinning process of the cashmere blended yarn is capable of reasonably matching the raw materials, thereby effectively reducing hairiness of the yarn; and a multi-combing and less-beating process is adopted, so that damage of cashmere fibers and cashmere falling are reduced, and the phenomenon that the cashmere easily winds a cylinder and a doffer is eliminated.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spinning process of cashmere blended yarn. Background technique [0002] In order to provide more and more comfortable textile materials for the field of knitted garments and reduce production costs, in recent years, the market has introduced a series of wool cotton (or viscose) yarns, the common ones are 45 / 55, 30 / 70 and 20 / 80 and other specifications of blended yarn. Because the wool component in the blended yarn is not resistant to strong alkali and cotton enzyme preparations, the scouring and bleaching processes commonly used in cotton cannot be used, so that impurities such as cotton wax, grease, pectin and natural pigments cannot be effectively removed, affecting It improves the handle style, as well as the hair effect and the stability of the bleaching and dyeing process. Cashmere fiber is a precious textile fiber among animal fibers. It has good fineness, softness, ...

Problems solved by technology

Because the wool component in the blended yarn is not resistant to strong alkali and cotton enzyme preparations, the scouring and bleaching processes commonly used in cotton cannot be used, so that impurities such as cotton wax, grease, pectin and natural pigments cannot be effectively removed, affecting Improve the hand style, as well as the stability of hair effect and dyeing process

Cashmere fiber is a precious textile fiber among animal fibers. It has good fineness, softness, and smooth handle. It is known as the "king of wool". It is carried out in a specific wool spinning factory, and cashmere needs to be processed on cotton spinning equipment, especially when it is blended with chemical fibers, there are defects such as uneven cashmere in the yarn, easy generation of static electricity in the production process, poor cohesion, and even affect the wearing performance of clothing.
