▎ 摘　　要

NOVELTY - Method for improving properties of graphene-modified fabric fibers or graphene-modified fabrics involve (i) melt-blending graphene and polymer chip in extruder, where the mass ratio of polymer chip and graphene is (100-1000):1, the polymer chip is a polymer material chip that can be made into fabric by spinning, the polymer chip comprises polyamide, polyethylene and/or polyester polymer material chip, (ii) drying the melt blended product and performing direct spinning to obtain graphene modified fabric fiber or graphene modified fabric, (iii) performing electron beam irradiation on graphene-modified fabric fiber or graphene-modified fabric, washing and drying to obtain the product, where the irradiation is electron irradiation with a dose of 30-1000 kGy, and when the polymer chip is polyamide, the irradiation dose is 30-60 kGy, when the polymer chip is polyester, the irradiation dose is 200-400 kGy, and when the polymer chip is polyethylene, the irradiation dose is 30-400 kGy. USE - The method for improving properties of graphene-modified fabric fibers or graphene-modified fabrics. ADVANTAGE - The method uses electron beam irradiation technology to improve the graphene modified fabric fiber or graphene modified fabric, enhances mechanical property, electrical property and anti-aging property, and is simple, economical and suitable for industrialized production.
