The wear-resistant composite filament has a sheath-core structure including core and sheath. The core is polyester fiber containing graphene modified polyester masterbatch. The sheath is nylon fiber containing graphene modified nylon masterbatch. The core contains 2-6% graphene modified polyester masterbatch. The sheath contains 1-5% graphene modified nylon masterbatch.
