NOVELTY - Anti-pilling polyester fabric based on silk fibroin-graphene oxide composite material comprises polyester fabric and the silk fibroin-graphene oxide composite material layer wrapped on the surface of polyester fabric. USE - Anti-pilling polyester fabric based on silk fibroin-graphene oxide composite material. ADVANTAGE - The polyester fabric has a series of functions such as anti-pilling, antibacterial and anti-ultraviolet, and the anti-pilling performance is improved by at least two levels, and the feel and luster of polyester fabrics modified by silk fibroin-graphene oxide are greatly improved, which greatly improves the grade and added value of polyester fabrics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of anti-pilling polyester fabric based on silk fibroin-graphene oxide composite material, which involves: (1) adding graphene oxide in sulfur oxychloride, where the mass/volume ratio of the graphene oxide mass in g to the volume of thionyl chloride in mL is 1:5-1:10, adding dimethylformamide, and the volume ratio of the dimethylformamide to thionyl chloride is 1:1-1:5, performing reflux reaction at 80 degreesC for 24 hours, and performing low-temperature vacuum drying to obtain the graphene oxide chloride; (2) adding the acyl chloride graphene oxide to deionized water, the liquor ratio is 1:50, and adding silk fibroin powder, the mass ratio of the acyl chloride graphene oxide and the silk fibroin powder is 1:1, stirring the reaction at room temperature for 24 hours, and repeatedly washing the obtained mixed suspension and drying in a low-temperature vacuum to obtain a silk fibroin-graphene oxide composite material; (3) immersing the polyester fabric after alkali reduction treatment in gamma-glycidyl ether oxypropyl trimethoxysilane to react for 24 hours, the liquor ratio is 1:20, and obtain the gamma-glycidyl ether oxypropyl trimethoxysilane modified polyester fabric by low temperature vacuum drying; (4) preparing silk fibroin-graphene oxide composite material into an aqueous solution with a mass fraction of 1-5%, immersing glycidyl ether oxypropyltrimethoxysilane modified polyester fabric in the silk fibroin-graphene oxide composite material aqueous solution and reacting at room temperature for 12-24 hours, the liquor ratio is 1:25, and low-temperature vacuum drying to obtain anti-pilling polyester fabric based on silk fibroin-graphene oxide composite.
