Manufacturing method of cotton and wool mixed spinning yarn

Abstract

The invention discloses a manufacturing method of cotton and wool mixed spinning yarn. The manufacturing method of the cotton and wool mixed spinning yarn comprises the following steps: S1, cutting Australian wool tops into short fibers, and using oil and water to prepare a emulsifier with a certain concentration to oil the Australian wool short fibers; S2, covering the oiled Australian wool shortfibers with a plastic film, standing for a set time, packing into bales, and then mixing on a disc grabbing machine according to the ratio of 60% cotton and 40% wool; and S3, performing blowing, carding, drawing, roving, spinning, and self-doffing in sequence to obtain the cotton and wool mixed spinning yarn. The invention uses oil and water to prepare the emulsifier with a certain concentrationto oil the Australian wool short fibers, covers the short fibers with the plastic film, and lets the short fibers stand for a certain period of time to make the emulsifier penetrate evenly, so as to reduce the mass specific resistance of the Australian wool fibers, reduce static electricity, improve the lubricity and flexibility of the Australian wool, reduce the friction resistance among the fibers, reduce the damage and breakage of the fibers during the carding process, and improve the spinnability; and therefore, the spinning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for making cotton wool mixed spinning yarn. Background technique [0002] Australian wool is a kind of animal protein fiber, which has the characteristics of good warmth retention, light texture, comfortable hand feeling, high elasticity, soft luster, good bulkiness, strong elastic recovery performance, excellent dyeability, high dyeing rate, bright color after dyeing, etc. , also has a unique shrinkage, and can weave fabrics with different styles. However, due to the thicker Australian wool fibers, high rigidity, poor cohesion, and low elongation, spinning and carding are not easy to form into slivers, high static electricity, easy to wrap around rollers, and poor yarn evenness, high end breakage, The serious hairiness and other shortcomings make it difficult to blend Australian wool and cotton, and the quality of the spun yarn is not high. [0003] There...
