Problems solved by technology

At present, there are many preparation methods of nano-copper sulfide, but most of them are carried out under the extreme conditions of high temperature and high pressure. The lack of simple and easy-to-operate nano-copper sulfide preparation methods with high photothermal efficiency restricts the product development of self-heating fiber products.

Abstract

The invention discloses a processing method of a cellulosic fiber product with a photothermal effect, and belongs to the technical field of functional textile processing. The method comprises the following steps: firstly, introducing vinyl on a cellulose fiber product, and then catalyzing graft polymerization of acrylic acid and N,N-methylene bisacrylamide on a fiber by virtue of horse radish peroxidase, so as to form a net-shaped template containing carboxyl on the surface of the fiber; and then soaking the cellulose fiber product in a copper ammonia solution, and adding sodium sulfide to promote in-situ deposition on the surface of the fiber to form nano copper sulfide particles, so as to obtain the cellulose fiber product with the photothermal effect. According to the a processing method, the illumination self-heating cellulose fiber product is prepared by an adhesive-free method, and meanwhile, an illumination rapid sterilization function is endowed to the cellulose fiber product; and therefore, the cellulose fiber obtains the relatively high photothermal effect, and the application performance of the cellulose fiber product is improved.

Description

technical field [0001] The invention relates to a method for processing cellulose fiber products with photothermal effects, belonging to the technical field of functional textile processing. Background technique [0002] Cellulose fiber products include woven fabrics, knitted fabrics or non-woven fabrics processed from cotton, hemp, viscose and tencel fibers, which have the advantages of soft hand feeling and good moisture absorption. fields are widely used. In recent years, attention has been paid to the development of functional cellulose fiber products, especially fiber products with self-heating function under certain conditions, which are popular in autumn and winter clothing and home textile materials. [0003] There are several different types of self-heating textiles, including heating by conduction, heating by light, and others. Conductive heating textiles are coated with conductive media such as carbon black, graphene, carbon nanotubes or conductive polymers (suc...
