Abstract

The invention provides a method for producing air spinning multi-component 20-count yarn. The yarn is characterized by being prepared from cotton fiber, polyester fiber and viscose fiber, wherein themass ratio of the cotton fiber to the polyester fiber to the viscose fiber is 9:6:5. The method for producing the air spinning multi-component 20-count yarn comprises a drawing step, wherein the feeding dry ration of drawing is 39.5-40 g / m, it is controlled that the dry ration of cotton carding slivers is 5.9-6 g / m, the dry ration of polyester carding slivers is 5.9-6 g / m, and the dry ration of viscose carding slivers is 4.9-5 g / m; and drawing comprises first doubling, second doubling and third doubling. The method for producing the air spinning multi-component 20-count yarn has the advantagesthat the evenness of the air spinning multi-component 20-count yarn can reach 12.0 CV%, and slubs and snicks are both less.

Description

technical field [0001] The invention relates to a production method of air-spun multi-component 20-count yarn, which is a production method of air-spun 20-count yarn composed of three raw materials of cotton, polyester and viscose, and belongs to the technical field of air-spun spinning. Background technique [0002] Today's air spinning market is dominated by pure cotton yarns, followed by the blending of viscose, polyester cotton, and viscose cotton. It mainly spins on the basis of traditional technology and domestic equipment. [0003] In the prior art, CN201210304951.9 discloses a bamboo shoot shell fiber and ramie fiber air-spinning blended yarn and its production method, using bamboo shoot shell fiber and ramie fiber as raw materials, through cleaning and mixing, carding, two drawing frames 1. Air spinning five process steps to complete its production method. The blending ratio of bamboo shoot shell fiber and ramie fiber is 35:65, and the count is 4.5S-14S; according ...
