▎ 摘　　要

NOVELTY - Graphene-type conductive sheath-core fiber comprises a core layer and a sheath layer. The core layer comprises polyester. The sheath layer comprises graphene, and/or composite material of carbon nano-tube and low-melting-point polyester. USE - Used as graphene-type conductive sheath-core fiber. ADVANTAGE - The conductive sheath-core fiber: has strong conductivity, where the best conductivity of the knitted fabric is 13.20 S/m (20 degrees C); has high washing fastness; and tightly combines the coating with the fiber surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the conductive sheath-core fiber, comprising continuously coating graphene dispersion liquid on the surface of the sheath-core fiber, where the graphene dispersion liquid comprises graphene and/or carbon nano-tube, and adhering the graphene to the surface of the sheath-core fiber by a hot-pressing method to obtain the graphene-type conductive sheath-core fiber.
