Problems solved by technology

[0002] Polyester is the fiber with the highest output of textile fibers and the most important raw material for textile products, accounting for more than 70% of the processing volume of textile fibers. Polyester fiber is a chemical synthetic fiber because of its high breaking strength, good light resistance, and crisp products. It is widely used in clothing and home textiles, mainly including coats, curtains, sofa fabrics, car interior accessories, etc. However, polyester is a superhydrophobic fiber with extremely poor hygroscopicity and rigidity, which li

Abstract

The invention provides a fibroin modification method for a polyester fabric. The fibroin modification method comprises the following steps: (1) performing desizing treatment on a polyester fabric to obtain a desized fabric; (2) processing the desized fabric with sodium hydroxide, and performing washing to obtain the fabric subjected to alkali treatment; and (3) dipping the fabric subjected to alkali treatment in a cross-linking agent solution, and performing a mixed reaction with silk fibroin with the molecular weight of 1,000-5,000 Da. According to the modification method, the fabric subjected to desizing treatment is processed with sodium hydroxide, and owing to alkali treatment, a polyester fiber molecular chain releases reactive sites; meanwhile, the fabric subjected to modification alkali treatment by silk fibroin with the defined molecular weight of 1,000-5,000 Da is adopted, and the silk fibroin with the specific small molecular weight is firmly introduced into the fiber surfaceof the polyester fabric by use of the covalent binding principle; the coolness, softness and anti-static property of the polyester fabric are improved; and meanwhile, the mechanical property is good,and the fibroin stability is excellent.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for modifying silk protein of polyester fabrics. Background technique [0002] Polyester is the fiber with the highest output of textile fibers and the most important raw material for textile products, accounting for more than 70% of the processing volume of textile fibers. Polyester fiber is a chemical synthetic fiber because of its high breaking strength, good light resistance, and crisp products. It is widely used in clothing and home textiles, mainly including coats, curtains, sofa fabrics, car interior accessories, etc. However, polyester is a superhydrophobic fiber with extremely poor hygroscopicity and rigidity, which limits its application in home textiles and certain clothing fields , such as summer cool clothing, underwear and bedding. [0003] The prior art has reported the research on silk fibroin-coated polyester. Polyester fibers or fabrics are brittle, e...
