Abstract

The invention discloses a preparation method of antiviral regenerated cellulose fibres, and fibres thereof. The preparation method comprises the following steps of: (1), mixing a monovalent copper compound with a carrier, adding a dispersing agent and a stabilizing agent, adjusting pH, then, grinding and mixing, and preparing copper ion antiviral paste; and (2), adding the copper ion antiviral paste and a chelating agent into cellulose spinning gel solution in a double injection manner, and then, spinning, so that the antiviral regenerated cellulose fibres are obtained. The antiviral regenerated cellulose fibres prepared by the invention contain polyvalent copper, can effectively inhibit microbial reproduction for a long time, and have relatively antiviral and antibacterial effects; and the fibres in the invention also can be blended and interwoven with other fibres, and used for producing different types of antiviral and antibacterial textiles.

Description

technical field [0001] The invention belongs to the field of functional fibers and textiles, and in particular relates to a preparation method of an anti-virus regenerated cellulose fiber and the fiber thereof, and more specifically relates to a copper ion anti-virus regenerated cellulose fiber and a preparation method thereof. Background technique [0002] Regenerated cellulose fiber is a fiber made from natural cellulose (cotton, hemp, bamboo, tree, shrub, etc.), which has good hygroscopicity, drapability, easy dyeing and biodegradability. Regenerated cellulose fiber has good spinnability. Short fiber can be spun purely or blended with other textile fibers. The fabric is soft, smooth, breathable, comfortable to wear, and has bright color and good color fastness after dyeing. [0003] With the improvement of people's requirements for quality of life and the pursuit of healthy life, textiles that can play antibacterial and antiviral functions are more and more popular. Silv...
