Abstract

The invention relates to the technical field of fibers, and discloses a preparation method of antibacterial and deodorant regenerated cellulose fibers.Artemisia argyi, green tea, kiwi fruits and other plants are selected as raw materials and subjected to ultrasonic extraction, polyphenol substances in the plants are extracted, microbial growth can be effectively inhibited, bacteria can be effectively killed, and the antibacterial effect is achieved; polyphenols contain a large number of phenolic hydroxyl groups and can be subjected to condensation, neutralization and other reactions with amido, ammonia and other groups, free peculiar smells in the environment are effectively removed, the purpose of deodorization is achieved, aldehyde groups on dialdehyde cellulose and plant extracted polyphenols are subjected to reaction and covalent crosslinking, long-term adhesion is achieved, loss is not prone to occurring in the washing process, and the washing effect is good. And the antibacterial deodorant fabric has the characteristics of being green and environment-friendly.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a method for preparing antibacterial and deodorizing regenerated cellulose fibers. Background technique [0002] Textile products play an irreplaceable role in people's daily life. With the rapid development of economy and social civilization, regenerated cellulose fiber is a renewable fiber prepared from natural cellulose through a series of chemical and physical changes. The regenerated cellulose fiber made of cellulose has the characteristics of good softness, comfort, good hygroscopicity, good dyeing performance and gloss, good biodegradability, easy spinning and processing, and is produced during the manufacturing process. It has little pollution and is an important raw material in the textile industry. In recent years, various functional products have emerged one after another. High-efficiency products such as antibacterial, deodorant, and anti-mite are favored by more and m...
