A kind of preparation method of antibacterial functional cellulose fiber

Abstract

The invention discloses a method for preparing antibacterial functional cellulosic fibers. The method comprises the steps of using a cross-linking agent for enabling cyclodextrin to be arranged on the cellulosic fibers in a stem grafting mode through a chemical reaction, then utilizing the cyclodextrin on the fibers to conduct clathration on antibacterial agents, and in the preparing process, conducting ultrasound pretreatment on a reaction system comprising the cyclodextrin, the cross-linking agent, a catalyst and the cellulosic fibers. According to the method, the defect that in the prior art, the solid loading efficiency of the cyclodextrin is low, the preparation time is short, the efficiency is high, the antibacterial and anti-infection functional cellulosic fibers with the slow-release performance and paper products of the cellulosic fibers can be manufactured, and the functional cellulosic fibers have good market prospects.

Description

technical field

[0001] The invention relates to a preparation method of an antibacterial fiber, in particular to a preparation method of an antibacterial functional cellulose fiber. Background technique

[0002] In life, people inevitably come into contact with various bacteria, fungi and other microorganisms. These microorganisms spread diseases through contact under suitable external conditions, thus affecting people's health and normal work, study and life. Life. Therefore, with the development of science and technology and the improvement of people's living standards, more and more attention has been paid to the research, development and production of antibacterial fibers.

[0003] Antibacterial fibers are made by introducing substances capable of inhibiting bacterial growth into the surface and interior of fibers by physical or chemical methods. The physical methods mainly include blend spinning method, composite spinning method and finishing method. The chemical met...
