Spinning process of multi-fiber blended yarn

Abstract

The invention discloses a spinning process of a multi-fiber blended yarn, which comprises the following steps of: (1) cotton fiber modification; (2) selecting a spinning raw material; (3) flower clearing and cotton carding; (4) drawing; (5) spinning. Compared with the prior art, the process has the advantages that the cotton fiber obtained after modification has higher cationic degree, the adsorption of the cotton fiber to the dyestuff is greatly improved, and the dyeing effect of the cotton yarn is improved; the blended yarn obtained by blending the modified cotton fiber, the ramie fiber andthe viscose fiber has the advantages of the three fibers, the blended yarn produced by using vortex spinning has the advantages of less feather, high yarn strength and good strip evenness.

Description

technical field [0001] The invention relates to the field of spinning, in particular to a spinning process of multi-fiber blended yarn. Background technique [0002] Viscose fiber is a kind of cellulose fiber. Viscose yarn and its fabric have the advantages of excellent hygroscopicity, softness, elegance and comfort, and have broad application prospects. Cotton yarn is a yarn processed by spinning cotton fibers. It is called cotton thread after plying. The fibers in the yarn are straight and parallel, with less knots, good luster, evenness and high strength. It is mostly used for weaving high-grade fabrics. However, when cotton yarn is dyed, its adsorption capacity for dyes is limited, and the dyeing effect is not ideal. Linen yarn is named for its coolness and breathability. Most of the raw materials of hemp yarn are pure yarns. Due to the development of the chemical fiber industry, blended hemp yarn raw materials such as polyester cotton, polyester hemp, and fiber cott...
