▎ 摘　　要

NOVELTY - A Cutting-resistant ultra-high molecular weight polyethylene composite fiber comprises ultra-high molecular weight polyethylene, expandable organosilicate clay, modified graphene and antioxidant. The expandable silicate clay is added in an amount of 0.1-10% of the total mass of the composite fiber, preferably 0.5-5%, more preferably 3%. The modified graphene is added in an amount of 0.1-5% of the total mass of the composite fiber, preferably 0.1-0.5%, and more preferably 0.4%. USE - Cutting-resistant ultra-high molecular weight polyethylene composite fiber (claimed). ADVANTAGE - The composite fiber is prepared by a simple without compounding other hard fibers. The ultra-high molecular weight polyethylene composite fiber has excellent cutting-resistance performance, so that the comfort of the fiber product is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of Cutting-resistant ultra-high molecular weight polyethylene composite fiber.
