Blended yarn spinning method

Abstract

The invention discloses a blended yarn spinning method. Blended yarn is composed of cashmere, synthetic fiber and viscose acetal fiber, and spinning is finished through manual blending, blowing, cotton carding, drawing and roving. The method has the advantages that manual blending is adopted for mixing of fiber, and the nonuniformity of cashmere in finished yarn is solved; the process that carding is conducted more times than striking in the blowing and cotton carding processes, anti-static coating powder is added, damage to cashmere fiber and fleece falling are reduced, and the phenomenon that cashmere winds the cylinder and doffer easily is solved; the twist of roving is increased, and the defects that adhering, breakage and loosening, caused by the features that the crispation number of cashmere is reduced, and the fiber is smooth, in the processing process 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.
