Preparation method for acrylic fibers/regeneration, silkworm bamboo fiber blended washable fabrics

Abstract

The invention discloses a preparation method for acrylic fibers / regeneration, silkworm bamboo fiber blended washable fabrics. The selected warp and weft material comprises, by weight, 40-90 parts of acrylic fiber, 20-45 parts of natural fiber, 6-12 parts of synthetic fiber, 60-95 parts of cotton fiber, 8-18 parts of super fine denier polyester, 50-90 parts of regenerated bamboo fiber, 11-20 parts of mulberry fiber, 1-8 parts of corn protein fiber, 5-8 parts of fine staple cotton fiber and 5-10 parts of villus fiber, wherein washable treatment and water-repellency treatment are sequentially between the slashing operation and air injection operation. The washable treatment is: dipping the fabrics in the composite rare earth finishing agent for 45-60 minutes and finishing the dipped fabrics with complex enzyme after drying. Through the reasonable proportion of the composite rare earth finishing agent, the preparation method for the acrylic fibers / regeneration , silkworm bamboo fiber blended washable fabrics can improve the washing strength of the regenerated bamboo fiber, solves the problem that the regenerated bamboo fiber blended fabrics is not washable, and improves the wear-resisting property of the bamboo fiber blended fabrics.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a method for making acrylic / regenerated and silkworm bamboo fiber blended washable fabrics. Background technique [0002] Acrylic fiber has better elasticity, second only to polyester, about 2 times higher than nylon; it has better shape retention; although the strength of acrylic fiber is not as good as polyester and nylon, it is 1-2.5 times higher than wool; the softening temperature of acrylic fiber is 190-230°C, second only to polyester in synthetic fibers; the light resistance of acrylic fiber is the best among all synthetic fibers; the strength of acrylic fiber only decreases by 20% after one year of exposure in the open air; the warmth retention of acrylic fiber is about 15% higher than that of wool; It can be blended with wool, and the products are mostly used for civil purposes, such as wool, blankets, knitted sportswear, tarpaulins, curtains, artificial fur, plush, etc...

AI Technical Summary

Problems solved by technology

[0003]Bamboo fiber is mainly composed of cellulose, hemicellulose and lignin, but the content of lignin in bamboo fiber is still high; bamboo natural Cellulose still belongs to the type I crystal of cellulose, the crystallinity is smaller than that of cotton, and the structure is looser; the cross-section of bamboo fiber is approximately circular, the cavity is small, and there are no bamboo nodes in the longitudinal direction; for bamboo fiber fabrics, due to the wet strength of bundle fibers Low, very short single fiber, bamboo fiber fabrics generally have low washing strength and are not washable
