Method for producing 30 counts of siro-spun slub yarns by pure spinning of tencel fibers

Abstract

The invention relates to a method for producing a 30-count siro spinningslubby yarnthrough mono-tencel fiber spinning. The 30-count siro spinningslubby yarn is produced through procedures that cotton is cleaned and combed, tencel fiber is pre-combined, the heads are combined, the tails are combined, and the yarn is roughed, refined, and spooled. In the cotton cleaning procedure, the cotton is finely grasped, is combed for multiple times and hit slightly, is uniformly mixed and pressed laterally, the hitting speed is reduced, and the cotton is slowly loosened; in the cotton combing procedure, the combing quality is improved, and the fiber damage is reduced; in the combination procedures, rear-area traction is intensified in the head combination procedure, the rear-area traction is reduced in the tail combination procedure, the quantity is slightly fixed, the pressure is boosted, the speed is slow, the cotton is uniformly fixed, the extension parallelism degree of fiber is increased, and bent fiber is reduced; in the yarn roughing procedure, the quantity is slightly fixed, the pressure is boosted, the speed is slow, and the twisting degree is large; in the yarn refining procedure, a siro spinning and intelligent slubby yarn device is additionally mounted on a yarn refining machine; in the spooling procedure, a pressurizing device is additionally mounted on an automatic spooling machine idle pressing line, and knots can be well tied. The slubby yarn provided by the invention is soft, smooth and comfortable, high in dry and wet resistance, good in air permeability and damp absorption property, good in water washing stability and rich in concave and convex three-dimensional feeling.

Description

technical field [0001] The invention relates to a method for producing 30 siro-spun slub yarns by pure spinning of tencel fibers. Background technique [0002] Tencel is a kind of cellulose fiber. It adopts solvent spinning technology. The dry strength is slightly lower than that of polyester, but it is obviously higher than that of ordinary viscose fiber. The wet strength is significantly improved compared with viscose. It has very high rigidity and good Dimensional stability after washing, high hygroscopicity, round or oval fiber cross-section, beautiful luster, soft hand feeling, good drapability, and good airiness. Generally speaking, Tencel has the softness of cotton; the high strength of polyester; and the warmth retention of wool. Tencel fiber, as a new type of green and environment-friendly cellulose fiber raw material, has become more and more popular among consumers. The characteristics of green environmental protection, health care, softness and beauty of Tencel ...

AI Technical Summary

Problems solved by technology

[0003] 1. Tencel fiber has strong rigidity and poor cohesion between fibers. Static electricity is easily generated during spinning, which affects the spinnability of fibers, and is prone to sticking, winding rollers, and cots;

[0004] 2. The surface of Tencel fiber is smooth, and the cohesion force is poor. When carding, the cotton net is easy to fall, and it is not easy to form a net;

[0006] 4. Tencel pure spun yarn has a smooth surface and is easy to detangle
