Spandex fiber-containing dry cleaning-resistant flame-retardant cashmere composite fiber and manufacturing method thereof

Abstract

The invention discloses a spandex fiber-containing dry cleaning-resistant flame-retardant cashmere composite fiber. The fiber is prepared from 22-28 parts by weight of Tibetan antelope wool, 15-18 parts by weight of white goose down, 17-19 parts by weight of mohair fibers, 19-24 parts by weight of rice straw pulp fibers, 12-15 parts by weight of spandex fibers, 14-17 parts by weight of cuprammonium fibers, 2-4 parts by weight of nanometer far-infrared ceramic powder, 1.2-3.5 parts by weight of decabromodiphenyl oxide, 7-9 parts by weight of polypropylene glycol, 3-5 parts by weight of acrylamide, 2-3 parts by weight of pregelatinized starch, 0.4-0.8 parts by weight of magnesium chloride, 0.5-0.9 parts by weight of nanometer titanium dioxide, 1-3 parts by weight of prepared rehmannia root, 2-5 parts by weight of dendranthema indicum var aromaticum, 3-4 parts by weight of poria cocos, 85-95 parts by weight of 1-ethyl-3-methylimidazolium acetate, 90-110 parts by weight of 1-allyl-3-methylimidazolium chloride, 20-24 parts by weight of an auxiliary agent and a proper amount of water. Multiple types of fibers and Tibetan antelope wool are blended and spandex fibers and cuprammonium fibers are added into the mixture so that the cashmere composite fiber is obtained. The cashmere composite fiber has characteristics of dry cleaning resistance of spandex fibers and antistatic properties of cuprammonium fibers. Through use of other fibers and effective components, the cashmere composite fiber has the advantages of flame retardation, wear resistance, good serviceability, good processability and wide application scope.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a dry-cleaning-resistant flame-retardant cashmere composite fiber containing spandex fibers and a manufacturing method thereof. Background technique [0002] Cashmere is a thin and curved high-grade natural fiber that grows on the outer cortex of goats and covers the roots of goats' coarse hair. It contains a lot of air and forms an air layer, which can defend against the invasion of external cold air and keep body temperature without lowering. Known as "fiber gem" and "fiber queen". Due to the scarcity of output, more importantly, its excellent quality and characteristics, with the characteristics of lightness, softness, smoothness and waxiness, are incomparable to all textile materials currently available to humans, so it is also called "soft gold". [0003] Cashmere is mainly produced in my country. Due to the limitation of species, goats consume more grassland an...

AI Technical Summary

Problems solved by technology

[0003] Cashmere is mainly produced in my country. Due to the limitation of species, goats consume more grassland and vegetation than sheep, and the input-output ratio is relatively low, which leads to a decline in the number of goats. In addition, due to changes in feeding conditions and For the improvement of goats, the fineness of cashmere is becoming thicker year by year; with the improvement of people's living standards, the demand for cashmere products is gradually expanding in terms of quantity, quality and function, and more and more wool spinning enterprises are involved in cashmere production , making the already scarce cashmere resources more expensive, which also brings great operational risks to many enterprises; cashmere fiber itself is a kind of natural protein, and its finished products must have many defects, such as being susceptible to insects , easy to pilling, easy to generate static electricity, not wear-resistant, not radiation-proof, low strength, etc.
