▎ 摘　　要

NOVELTY - Graphene bifunctional knitted fabric comprises graphene composite fiber layer and a common fiber layer. USE - Graphene bifunctional knitted fabric. ADVANTAGE - The graphene bifunctional knitted fabric used on knitted sports fabrics to exert the high thermal conductivity of graphene nylon composite fiber and the unique far-infrared heating function, which makes sports enthusiasts comfortable to wear, and has a very broad application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene bifunctional knitted fabric, which involves weaving layer of the graphene composite fiber and the layer of the ordinary fiber by a large circular machine that is a double-layer graphene bifunctional knitted fabric.
