NOVELTY - Deeply-degrading graphene waste polyester textile by copolymerization modification comprises mixing polyester oligomer obtained by alcoholysis of the waste polyester textile with graphene oxide, and subjecting to polycondensation reaction to obtain graphene block regenerated copolyester, where the polyester oligomer has a number average molecular weight of 1000-3000 g/mol, and the graphene block regenerated copolyester is mainly composed of a carboxy group on the graphene and a hydroxy group on the polyester. USE - The material is useful in the field of antistatic, anti-ultraviolet and far-infrared. ADVANTAGE - The copolyester has short reaction time and is economical.
