AI Technical Summary

Technical Problem

Existing antibacterial and deodorizing fibers have problems such as easy shedding of antibacterial agents, short-lasting deodorizing effects, controversial biosafety, and functional imbalance.

Method used

A chitosan-tannic acid cross-linking system was used with modified zinc oxide and ZIF-8/tea tree oil composite nanoparticles to construct a stable structure in the core layer. ε-polylysine and green tea polyphenols were introduced into the shell layer to achieve synergistic antibacterial and deodorizing effects. The antibacterial and deodorizing fibers were prepared by coaxial wet spinning.

Benefits of technology

It significantly improves the antibacterial and deodorizing effects of the fiber, improves the stability of the antibacterial agent and the deodorizing durability, and achieves synergistic enhancement of antibacterial and deodorizing effects.
