A production and processing method of worsted cotton wool blended yarn

Abstract

The invention relates to a production and processing method of worsted cotton-wool blended yarn, comprising the following steps: A, making colored cotton slivers, first dyeing cotton fibers to make colored cotton loose fibers, and then dyeing colored cotton loose fibers Put it into the carding machine and comb it into slivers, then carry out pre-drawing, coiling, combing, and drawing, so as to make colored cotton slivers with uniform thickness; Colored wool tops, and then the dyed colored wool tops are needled, re-combed, and needled, and finally balled into colored wool tops with uniform thickness; C. Mix colored cotton slivers and colored wool tops on a carding machine , and then put the mixed sliver into a non-twisted wool type roving frame for three rovings, then put it into a spinning frame for one spun yarn, then wind, doubling, and double twisting to make worsted cotton wool blended yarn, The yarn produced by the processing method of the invention has uniform dryness, and the woven fabric has strong anti-pilling performance.

Description

【Technical field】 [0001] The invention relates to the technical field of spinning, in particular to a production and processing method of worsted cotton wool blended yarn. 【Background technique】 [0002] In the textile industry, wool fiber is popular with consumers for its excellent comfort, but its production cost is relatively high. In order to reduce its production cost, the industry usually uses wool fiber to blend with other fibers to reduce production costs. Because cotton The fiber also has good moisture-absorbing and sweat-conducting properties, so blending it with wool fiber has become a common choice in the industry. Cotton-wool blended yarns in the prior art can only be produced on semi-worsted spinning or mule spinning because of the large dispersion of fiber length and length, and are limited by the production process, and cannot be produced on worsted spinning. The following common problems occur in the production process: Technical problems: 1. Unevenness and...

Problems solved by technology

Cotton-wool blended yarns in the prior art can only be produced on semi-worsted spinning or mule spinning because of the large dispersion of fiber length and length, and are limited by the production process, and cannot be produced on worsted spinning. The following common problems occur in the production process: Technical problems: 1. Uneven dryness and poor anti-pilling ability; 2. Contains short fibers and poor fiber straightness
