Abstract

The invention discloses a semi-worsted yarn-dyed knitting yarn, which is composed of the following components in parts by weight: 30-36 parts of viscose, 20-26 parts of nylon, and 15-21 parts of cotton 15-21 parts of wool, 3-7 parts of cashmere, 3-7 parts of rabbit hair. The production process of semi-worsted yarn-dyed knitting yarn includes the following steps: 1) dyeing; 2) wool; 3) carding; 4) drawing; 5) roving; 6) spun yarn; line; 9) double twisting. The present invention is a semi-worsted yarn-dyed knitting yarn blended from six kinds of raw materials. The yarn is smooth, has good hygroscopicity and warmth-retaining performance, good elongation, good luster, and soft hand feeling. Its production process is pre-spun It is a wool spinning process, and the post-spinning is a cotton spinning process.

Description

technical field [0001] The invention relates to a yarn and a production process, in particular to a semi-worsted yarn-dyed knitting yarn and a production process thereof. Background technique [0002] The dry strength of viscose fiber is lower than that of cotton, and its wet strength is only about 50% of the dry strength. The elastic recovery ability is poor, it is not wear-resistant, not light-resistant, alkali-resistant and acid-resistant; but viscose fiber has good hygroscopicity and is easy to dye. The fabric is comfortable to wear. Blending it with synthetic fibers can improve the wearability of the fabric. [0003] Nylon has better resilience, fatigue resistance and thermal stability at a lower melting point, and also has better elongation. [0004] The yarn spun from combed cotton is finer and of better quality, and the fabrics made of combed cotton have a higher quality level in terms of texture, washability and durability. [0005] Wool is an important raw mater...
