A kind of grass coral high-efficiency antibacterial and antiviral cellulose fiber and its preparation method

Abstract

The invention provides a kind of grass coral high-efficiency antibacterial and antiviral cellulose fiber, the fiber, the content of chitosan-functional component composite particles is 9.5-9.7%, and the content of silicic acid composite colloid is 2-3.5%; the present invention Also provided is a method for preparing grass coral high-efficiency antibacterial and antiviral cellulose fibers, including preparing chitosan-functional component composite particles, preparing silicic acid composite colloids, blending, and spinning. The present invention reduces the loss or loss of functional components during the fiber preparation process; the functional components of the fibers prepared by the present invention are distributed on the fiber cortex and surface; the fibers prepared by the present invention are embedded in the fiber cortex or surface in granular form The functional components are firmly combined with the fiber, and there is little loss during washing and friction; the fiber of the present invention can effectively resist influenza A virus and influenza B virus, and has high resistance to Staphylococcus aureus, Candida albicans, and Salmonella typhi inhibition rate.

Description

technical field [0001] The invention relates to a viscose fiber, in particular to a grass coral high-efficiency antibacterial and antiviral cellulose fiber and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] The development of functional fibers is a symbol of the progress of modern fiber science. The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. [0003] Banlangen is an excellent traditional Chinese medicinal material, which has the functions of antibacterial, antiviral, antitumor and improving immune function; the extra...

AI Technical Summary

Problems solved by technology

[0007] (1) During the fiber preparation process, extracts of isatidis root, grass coral extract and mint are easily soluble in water and cause loss, and are also easily damaged by acid and alkali to cause loss;

[0008] (2) In the prior art, the functional components are generally blended with the spinning dope, and then sprayed into the coagulation bath for spinning, because the distribution of the functional components in the fiber is random, that is to say, a large number of functional components will Distributed in the core layer of the fiber, distributed on the surface of the fiber or less in the cortex; because the extracts of isatidis root, grass coral extract, and peppermint are all contact antibacterial and antiviral, so only the function of distributing on the fiber cortex or surface Active ingredients will work, so a large number of functional ingredients are distributed inside the fiber core layer, causing a lot of waste and increasing production costs;

[0009] (3) The functional components on the surface of the fiber will also be lost during washing and friction, thereby reducing the antibacterial and antiviral effect of the fiber
