Spinning method of blended yarns

Abstract

The invention discloses a spinning method of blended yarns. The blended yarns consist of cashmere, synthetic fibers and viscose fibers, and spinning is completed by steps of artificial mixing, cotton cleaning, cotton carding, drawing and roving. The spinning method has the advantages that in the spinning method, mixing of the fibers adopts artificial mixing, so that the problem of unevenness of the cashmere in the finished yarns is solved; in the steps of cotton cleaning and cotton carding, a process of carding a lot and beating a little is adopted and a powder antistatic coating is added, so that damage to the cashmere fibers and cashmere falling of the cashmere fibers are reduced, and the problem of a phenomenon that the cashmere can easily wind a cylinder and a doffer is solved; a twist degree of roving is improved, so that the defects of viscosity, damage and loosening in the spinning machining process, which are caused by the characteristics that the crimp number of the cashmere is reduced and the fibers are smooth, are overcome.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning method of blended yarns. 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 gauge blended yarns. 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, and smooth handle. I...

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.
