Cotton fiber and viscose blended yarn and manufacturing method thereof

Abstract

The invention discloses a cotton fiber and viscose blended yarn and a spinning technology thereof. The blended yarn comprises cotton fiber and viscose, and the fiber blending ratio of the cotton fiber to the viscose is 1:1; and the fibers are spun into yarns through a blending process. Card slivers formed by the processes such as blowing and carding and cotton fiber combed silvers are subjected to silver blending to form yarns, and a compact Silo spinning technology and the reasonable matching of raw materials are adopted, so that the problems such as the viscose can be deformed easily, has low elastic recovery performance and relatively low wear resistance, and is not acidproof are solved, and the advantages of the viscose and the cotton fiber are exerted. A pre-doubling and mixed doubling mixing mode is adopted, so that the accuracy of the blending ratio and the uniformity of ingredients are facilitated, produced single yarns have uniform yarn levelness and high strength, and few neps and yarn faults are produced.

Description

Technical field [0001] The invention relates to the technical field of spinning, in particular to a method for spinning cotton fiber and viscose fiber blended yarn. Background technique [0002] With the increasing development of the social economy and the improvement of people’s living standards, people’s consumption concepts are constantly updated, they are paying more and more attention to the quality of life and living environment, and the functional requirements of clothing are getting higher and higher, especially for the health care of clothing. The requirements in terms of, feel and quality have also been continuously improved. Viscose fiber refers to a-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...

AI Technical Summary

Problems solved by technology

Its modulus is lower than that of cotton, it is easy to deform under a small load, and its elastic recovery performance is poor, so the fabric is easy to elongate and its dimension stabil...
