NOVELTY - A composite fiber comprises 84-99 %mass nylon slices, 0.1-15 %mass white graphene and 0.1-1 %mass modifier. USE - Composite fiber. ADVANTAGE - The composite fiber has excellent antibacterial property, far-infrared resistance and UV resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite fiber, which involves weighing raw materials, drying nylon slices and white graphene, grinding the nylon slices to obtain nylon slice powder, adding white graphene powder and modifier, mixing, stirring to obtain white graphene nylon mixed powder, adding the white graphene nylon mixed powder to twin-screw extruder, extruding, granulating to obtain modified white graphene nylon masterbatch, drying, placing in twin-screw extruder, heating and spinning.
