Problems solved by technology

[0008] (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;
[0009] (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 Functional 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;
[0010] (3) The functional components on the fiber surface will also be lost during washing and friction, thereby reducing the antibacterial and antiviral effect of the fiber

Abstract

The invention provides a preparation method of high-hygroscopicity sarcandra glabra antibacterial and antiviral cellulose fiber. The preparation method includes: preparing silicic acid compound glue:well mixing a sodium silicate water solution with sodium hyaluronate and starch monosuccinate, adding a crosslinking agent N, N-methylene bisacrylamide and a polymerization initiator sodium persulfateto obtain a mixed material. Dry breaking strength of the antibacterial and antiviral cellulose fiber prepared by the method is 2.80-2.85cN / dtex, and the cellulose fiber is high in hygroscopicity.

Description

[0001] The present invention is a divisional application of application number 2017101832704, application date March 24, 2017, and invention name "A kind of grass coral high-efficiency antibacterial and antiviral cellulose fiber and its preparation method". technical field [0002] 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 [0003] 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 fu...
