Hydrophobic modified antimicrobial cashmere fiber and manufacturing method of hydrophobic modified antimicrobial cashmere fiber

Abstract

The invention discloses hydrophobic modified antimicrobial cashmere fiber. Chitosan fiber and cashmere are creatively blended, so that chitosan is uniformly distributed, cannot easily fall off and can be combined with saliva of bacterial microbe phospholipids; the chitosan is permeated and enters cell bodies to be adsorbed; the normal physiological activities of cells are disturbed, so that bacteria are killed; the bactericidal effect is durable; in addition, bamboo charcoal polyester fiber is adopted for replacing the partial cashmere fiber; the cost is reduced; various technical indexes of cashmere are also improved; added carbon nanotubes generate carboxyl and hydroxyl groups after being subjected to mixed acid oxidation modification; after the carboxyl and hydroxyl groups are added into raw materials, good dispersibility and good stability are realized. The prepared cashmere fiber adopts methacrylamide as a grafting monomer for surface grafting decoration modification; the prepared cashmere fiber has a hydrophobic antibiosis function, a far infrared function and a negative ion functions; the hand feeling of fabrics is soft; the heat insulation and comfort functions are good; the cashmere fiber is suitable for being made into casual clothes and underwears.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a hydrophobically modified antibacterial cashmere fiber and a manufacturing method thereof. Background technique [0002] Cashmere has the characteristics of fineness, lightness, softness, smoothness, and good thermal performance, but its output is scarce. It is called "fiber diamond" and "soft gold" and is a high-grade textile raw material. Due to the scale structure on the surface of cashmere fiber, its products have problems such as easy felting and pilling during use. In addition, cashmere fiber itself is a natural protein that is easy to be eaten by insects. The traditional post-treatment method is often modified by dipping in antibacterial liquid. Often there is the shortcoming that antibacterial effect is not permanent. With the advancement of science and technology and the development of society, accompanied by ubiquitous electromagnetic radiation, air pollut...

Problems solved by technology

Due to the scale structure on the surface of cashmere fiber, its products have problems such as easy felting and pilling during use. In addition, cashmere fiber itself is a natural protein that is easy to be eaten by insects. The traditional post-treatment method is often modified by dipping in antibacterial liquid. There are often defects that the antibacterial effect is not long-lasting
