Abstract

The invention discloses a preparation method of an anti-bacterial and mite-proof sulfur-containing viscose fiber. The method comprises steps as follows: an NMMO (N-methylmorpholine-N-oxide) spinning solvent with the certain moisture content is prepared in advance at a certain temperature; then cellulose powder with the certain mass fraction is added to the prepared spinning solvent, the mixture is stirred for a certain period while the certain temperature is kept, cellulose is fully dissolved, and a cellulose spinning solution is prepared; the cellulose spinning solution is quickly cooled to the specific temperature, certain sublimed sulfur is mixed to be used as an anti-bacterial and mite-proof functional component, blending and stirring are performed, and an evenly-dispersed sulfur-containing cellulose spinning solution is obtained; water is used as a solidification liquid, the spinning solution is extruded into the solidification liquid from a spinning orifice plate, the spinning solution is gradually lengthened and fine-drawn during quick solidification, and the sulfur-containing viscose fiber with anti-bacterial and mite-proof functions is prepared. The method solves problems that existing preparation methods are high in cost and low in safety and washability is poor, the functional component of the prepared fiber is evenly distributed, and the fiber is washable, safe, lasting in anti-bacterial and mite-proof effect and widely applicable to production of underwear, bedding and air filter materials.

Description

technical field [0001] The invention designs and develops a method for preparing antibacterial and anti-mite sulfur-containing viscose fibers, which belongs to the field of textile fiber production by wet spinning with anti-bacterial and anti-mite functional components. Background technique [0002] At present, antibacterial and anti-mite methods are mainly divided into chemical anti-mite and physical anti-mite. Chemical anti-mite mainly uses anti-mite agents to kill or avoid mites, including trapping and killing methods to prevent mites from multiplying, and using evasive methods. Keep mites away; physical anti-mite is mainly a blocking method to prevent mites from passing. However, the prevention and control of mites in the world is mainly aimed at agricultural mites. Because of safety issues, it is very difficult to implement anti-mite in the textile industry. People hope to find a new material preparation method, which not only ensures that the material has a long-lasti...
