Spinning method of large-difference AB slubby yarn through siro-compact spinning

Abstract

The invention provides a spinning method of large-difference AB slubby yarn through siro-compact spinning. A raw material A and a raw material B which are different in dyeing property or color are subjected to opening, carding, combing preparation, combing, drawing and roving according to processing needs respectively, and rough yarn A and rough yarn B are separately prepared. The weight ratio of the rough yarn A to the rough yarn B under the commercial moisture regain is 3 or more, then on a four-roller siro-compact spinning machine with a slubby control device, the rough yarn A and the rough yarn B are fed into a drafting zone through a double-hole horn mouth and output after drafting and compacting, the output fiber strand is twisted to form yarn in a dislocation spinning mode, and then the large-difference AB slubby yarn is produced. An antistatic agent accounting for 0.3% by dry weight of the raw material rough yarn B and water accounting for 3% by dry weight of the raw material rough yarn B are mixed to form a mixed aqueous solution, the mixed aqueous solution is uniformly sprayed on the raw material rough yarn B, and then the raw material rough yarn B is laid up for 24 hours in a sealed mode for enzymatic treatment. On the four-roller siro-compact spinning machine, transmission between a middle rear roller and a front roller is cut off, and the dislocation spinning mode is adopted in the spinning process.

Description

technical field [0001] The invention relates to a spinning method, in particular to a Siro compact spinning method with large difference AB slub yarn. Background technique [0002] In recent years, the situation of the textile industry has continued to slump, and the market competition has become increasingly fierce. The single product variety structure of traditional cotton spinning enterprises can no longer meet the diversified market demand. It is imminent to adopt new technologies, develop new products, and drive enterprise transformation and upgrading with innovation. [0003] The traditional AB slub yarn spinning technology is to spin two kinds of fibers with different dyeing properties or different colors into roving respectively, and then merge and twist them on the same spindle to form yarn. Due to the small difference in the thickness ratio of the two rovings, generally within 1:1 or 3:2, the dyed fabric not only has a three-dimensional concave-convex effect, but ...

AI Technical Summary

Problems solved by technology

Due to the small difference in the thickness ratio of the two rovings, generally within 1:1 or 3:2, the dyed fabric not only has a three-dimensional concave-convex effect, but also has a single color change, and is mostly spun on a three-roller spinning frame. Too much thread hairiness, low strength, and the quality cannot meet the requirements of high-end fabrics

When spinning AB slub yarn with a large difference in ratio, the roving strands with a small ratio are prone to escape after drafting, resulting in the loss of B component, causing rungs to appear on the cloth surface after dyeing, and reducing product quality
