Viscose fiber and leecy fiber blended yarn and spinning technology thereof

Abstract

The invention discloses a viscose fiber and leecy fiber blended yarn and a spinning technology thereof. The blended yarn comprises viscose fibers with the fiber content blending ratio of 60-70%, and leecy fibers with the fiber content blending ratio of 30-40%. The fibers are woven into the yarn through the spinning technology. Firstly, after the leecy fibers are subjected to opening and picking and cotton carding, the leecy fibers and the viscose fibers are mixed, then opening and picking and cotton carding are carried out, and the leecy fibers and the viscose fibers can be mixed to be uniform; due to the fact that the leecy fibers with the durable physical bacteriostasis function are added, the viscose fiber finished products can be prepared into the yarn with the antibacterial function directly through the following spinning technology, it is not needed to independently carry out antibacterial treatment on the viscose fiber finished products, the technology is simplified while the antibacterial effect is guaranteed, the production cost is reduced, fabric woven from the viscose fiber and leecy fiber blended yarn can be rapidly dyed, the colors are gorgeous, gradually varied and rich in layering sense after the fabric is colored, and multiple colors can be obtained through one time of dyeing.

Description

Technical field [0001] The invention belongs to the technical field of spinning, and specifically relates to a blended yarn of viscose fiber and Li Cai fiber and a spinning process thereof. Background technique [0002] Viscose fiber refers to α-cellulose extracted from cellulose raw materials such as wood and plant ligustrum, or cotton linters as raw materials, processed into spinning dope, and then wet-spinned to make artificial fibers. Viscose fiber has good moisture absorption. Under normal atmospheric conditions, the moisture regain rate is about 13%. After absorbing moisture, it expands significantly, and the diameter increases by up to 50%, so the fabric feels hard and has a large shrinkage rate after being launched. The breaking strength of ordinary viscose fiber is smaller than that of cotton, about 1.6 ~ 2.7 cN / dtex; the elongation at break is greater than that of cotton, which is 16% to 22%; the wet strength decreases more, about 50% of the dry strength, and the wet e...

AI Technical Summary

Problems solved by technology

Although the viscose fiber has a long-lasting antibacterial function and has no side effects on the human body, this method needs to add antibacterial substances in the production process of the viscose fiber, and most of the viscose fiber finished products are directly produced without antibacterial treatment at present. If the finished product of viscose fiber is required to have antibacterial function, it needs to be treated with antibacterial treatment before the subsequent spinning process, and the finished product of viscose fiber is directly treated with antibacterial treatment. On the one hand, its antibacterial effect cannot be effectively guaranteed; It will increase the process procedure, increase the cost, and waste time and effort
