Problems solved by technology

Adding nano-silver to underwear fabrics has a long history of making antibacterial underwear, but they generally add nano-silver particles in the process of making synthetic fibers, or soak the cloth in a silver-containing solution, and then let the silver Adsorption is deposited on the surface of the cloth; the defect of the former is that the artificial synthetic fiber is not skin-friendly enough, and the air permeability is not good; the defect of the latter is that the silver particles deposited on the surface of the cloth are not stable enough, and it is easy to fail after repeated washing

Abstract

The invention discloses a multi-effect regenerated cellulose fiber. The multi-effect regenerated cellulose fiber is mainly prepared from hydroxyl ferrite nano-powder, silver nano-powder, guanidine carbonate, phthalimide, sodium hydroxide and regenerated bamboo cellulose through a viscose spinning process, wherein the hydroxyl ferrite nano-powder and the silver nano-powder are prepared by making nitrate containing metal ions and low-polymer chitosan perform complexing reaction and then making a reactant react with ammonia water or hydrazine hydrate. The prepared multi-effect regenerated cellulose fiber has a good antibacterial effect and a magnetic therapy health-care effect, and a manufactured fabric is soft and comfortable and good in air permeability, does not easily produce static electricity, is resistant to washing and rubbing and is extremely convenient to finish.

Description

technical field [0001] The invention belongs to the field of clothing fabrics, in particular to a multifunctional regenerated cellulose fiber. Background technique [0002] Regenerated cellulose fiber (cellulose fiber) is made of natural cellulose (cotton, hemp, bamboo, trees, shrubs, etc.), without changing its chemical structure, only changing the physical structure of natural cellulose, so as to produce better performance Regenerated Cellulose Fiber. Its structure is similar to cotton, the difference is that its hygroscopicity and air permeability are better than cotton fibers, it can be said that it is the best hygroscopicity and air permeability of all chemical fibers, known as "breathing fabric" . The regenerated cellulose fiber fabric feels soft, smooth and cool, and is not prone to static electricity. It has the softness of cotton, the luster of silk, and the smoothness of linen; it is comfortable and close-fitting, breathable and moisture-absorbing, and has good ...
