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 limits its application in home textiles and certain clothing fields , such as summer cool clothing, underwear and bedding, etc.
[0003] The prior art has reported the research on silk fibroin-coated polyester. Polyester fiber or fabric coating is brittle, easy to break and fall off, and will affect the surface structure and even air permeability of the original fabric.
There are also reports in the literature that the weight gain rate of silk fibroin coating is low, the washing resistance is not ideal, or the moisture regain is still very low
so no market adoption

Abstract

The invention provides a protein modification method of polyester fabric. The method comprises the following steps: performing desizing treatment on the polyester fabric, so as to obtain desized fabric; treating the desized fabric with sodium hydroxide, and washing the fabric, so as to obtained fabric subjected to alkali treatment; soaking the fabric subjected to alkali treatment into cross-linking agent solution, and ensuring that the fabric is mixed and reacted with silk fibroin with the molecular weight being 1000 to 5000Da; ensuring that a cross-linking agent comprises polyethylene glycoldiglycidyl ether. The modification method ensures that the fabric subjected to desizing treatment is treated through sodium hydroxide, and alkali treatment ensures that reaction sites are released onpolyester fiber molecular chains; meanwhile, the fabric subjected to alkali treatment is modified by the silk fibroin with the molecular weight being limited to 1000 to 5000Da, the silk fibroin with specific small molecular weight is firmly led to the fiber surface of the polyester fabric through a principle of covalent binding, the coolness, softness and antistatic property of polyester fabric are improved, meanwhile the mechanical property is good, and the silk protein is good in stability.
