A kind of cotton fiber, viscose fiber blended yarn and its manufacturing method

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 blending cotton fiber and viscose fiber. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's consumption concept is constantly updated, and people pay more and more attention to the quality of life and living environment, and the functional requirements for clothing are also getting higher and higher, especially for the health care of clothing. , feel, quality and other aspects of the requirements are also constantly improving. Viscose fiber refers to a-cellulose extracted from cellulose raw materials such as wood and plant stalks, or artificial fibers made from cotton linters, processed into spinning stock solution, and then wet-spun. Viscose fiber has good hygroscopicity, and the moisture regain is about 13% under general atmospheric conditions. After absorbing moisture, it swells signif...

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 stability is poor

The chemical composition of viscose fiber is similar to that of cotton, so it is more resistant to alkali than acid, but its resistance to alkali and acid is worse than that of cotton
