Sarcandra glabra high-efficiency antibacterial antiviral cellulosic fiber and preparation method thereof

Abstract

The invention provides sarcandra glabra high-efficiency antibacterial antiviral cellulosic fiber. The fiber is prepared from chitosan-functional ingredient compound particles and silicic acid compound colloid, wherein the content of the chitosan-functional ingredient compound particles is 9.5 to 9.7%, and the content of the silicic acid compound colloid is 2 to 3.5%. The invention further provides a preparation method of the sarcandra glabra high-efficiency antibacterial antiviral cellulosic fiber. The preparation method comprises the steps of preparing the chitosan-functional ingredient compound particles, preparing the silicic acid compound colloid, blending, and spinning and molding. In a preparation process of the fiber disclosed by the invention, running off or loss of functional ingredients is reduced; according to the prepared fiber, the functional ingredients are distributed on fiber cortex and surface portions; according to the prepared fiber, the functional ingredients which are embedded in the fiber cortex or surface in a particle shape are firmly combined with the fiber, so that loss is small in a washing and friction process; the fiber disclosed by the invention can effectively resist influenza A virus and influenza B virus, and also has higher inhibition ratios on staphylococcus aureus, candida albicans and typhoid bacillus.

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
