A preparation method of flax semi-bleached yarn with dyeing differentiation

Abstract

The invention provides a flax half bleached yarn manufacturing method with dyeing differentiation. The method comprises: dividing flax roving into two groups, using two different chemical treatment processes to treat, and then feeding the flax roving obtained after the two different chemical treatment processes into a drafting region of spun yarns, through drafting, twisting to spin a single yarn, similar to siro spinning, finally drying and spooling and forming, to manufacture a flax half bleached yarn with dyeing differentiation. After the spun flax half bleached yarn with dyeing differentiation is dyed, the yarn has color spun style, but evenness, strength, and yarn hairness are superior to evenness, strength, and yarn hairness of a flax long ramie color spun yarn. The manufacturing process is shorter than technological process of a color spun yarn. The method is low in manufacturing cost and good in spinnability. The novel differentiation linen expands and enriches kinds of flax yarn products, and is suitable for yarn dyeing and grey dyeing, and has good weaving selectivity. Fabric styles are unique, and the flax half bleached yarn has good market competitiveness and good market prospect.

Description

technical field [0001] The invention relates to a preparation method of flax semi-bleached yarn with dyeing differentiation, belonging to the technical field of textile industry. Background technique [0002] The market competitiveness of the traditional flax semi-bleached yarn is gradually weakening. In order to further develop the domestic and foreign flax market, the differentiated flax yarn is conducive to the development and utilization of linen clothing products, and then promotes market consumption. [0003] The existing flax long linen colored spinning is to dye the sliver, then mix different colors according to a certain ratio, and spin the colored spinning yarn. Its technological process is long and the production cost is high; the uniformity of the dyed sliver is also relatively poor, and after the sliver is bleached, dyed and dried, the fibers are bonded together, which is difficult to merge and draw; The drawing roving process results in longer spun yarn hairin...

AI Technical Summary

Problems solved by technology

The technological process is long and the production cost is high; the uniformity of the dyed sliver is also poor. After the sliver is bleached, dyed and dried, the fibers are bonded together, which makes it difficult to merge and draw; The drawing roving process results in longer spun yarn hairiness and more hemp particles, especially the loss of yarn strength, resulting in low spinning line strength index, which is difficult to meet the existing weaving requirements of weaving and hinders the diversity of products to develop
