Problems solved by technology

[0005] At present, the anti-ultraviolet fabric is mainly prepared by post-finishing. This method not only improves the anti-ultraviolet performance of the fabric, but also has a certain damage to the wearing performance of the fabric, and the anti-ultraviolet performance of the fabric will decrease with the increase in the number of washings.
The preparation of hygroscopic and exothermic fabrics is mainly through pre-spinning injection, and the hygroscopic and heat-generating fibers prepared by this method have the problem of serious damage to fiber strength.
[0006] The research and preparation of functional protein tencel fibers have not been reported yet, and the development of a functional protein tencel fiber has broad market prospects

Abstract

The invention provides an ultraviolet-resistant moisture absorbing and heating protein tencel fiber and a preparation method thereof. The preparation method comprises the steps: dissolving cellulose pulp into an N-methylmorpholine-N-oxide aqueous solution, and carrying out modification by using a sulfhydryl compound under the action of a molecular sieve based catalyst to obtain a modified cellulose spinning mother solution; carrying out enzymolysis on wool in water by using a protein-disulfide reductase and a solid protease to obtain a keratin solution; and mixing the keratin solution and themodified cellulose spinning mother solution, and then, preparing the ultraviolet-resistant moisture absorbing and heating protein tencel fiber by using a dry-jet wet spinning method. The protein tencel fiber prepared by using the preparation method has relatively high protein content and has ultraviolet-resistant moisture absorbing and spontaneous heating functions, and both the wet breaking strength and dry breaking strength of the fiber are improved.

Description

technical field [0001] The invention belongs to the technical field of textile fibers, and relates to a modified cellulose fiber with relatively high protein content and a preparation method of the modified cellulose fiber. The modified cellulose fiber of the invention has the functions of anti-ultraviolet and moisture absorption and self-heating. Background technique [0002] Now people are increasingly pursuing green and environmentally friendly textile products. Tencel is a kind of regenerated cellulose produced by making wood pulp from wood, directly dissolving it in N-methylmorpholine-N-oxide (NMMO) / water system to form a cellulose solution, and then making it through dry spray wet spinning fiber. Since the recovery rate of the solvent NMMO after spinning is over 99.5%, and it is non-toxic and non-polluting, Tencel is known as the green fiber of the 21st century. [0003] Regenerated cellulose fiber has good hygroscopicity, but its moisture conductivity is poor, and ...
