▎ 摘　　要

NOVELTY - Graphene polyester fiber comprises a sheath layer and a core layer composite structure. The core layer is graphene polyester slice or graphene polyester masterbatch. The sheath layer is a polyester slice. USE - The graphene polyester fiber is useful for manufacturing fabric and clothes (claimed). ADVANTAGE - The graphene polyester fiber can be easily dyed into light color. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) manufacturing graphene polyester fiber, comprising either mixing the graphene particles with polyester slice to obtain graphene polyester slice as a core layer, taking polyester slice as sheath layer, then subjecting to spinning process, or adding graphene particles into a solvent with sodium hexametaphosphate in glycol solution to obtain graphene glycol liquid, transferring the glycol solution of graphene into polyethylene terephthalate-lined polycondensation kettle to obtain graphene polyester particles, taking the graphene polyester particles as core, and the polyester slices as sheath layer, subjecting to spinning and processing; (2) fabric, spun by graphene polyester fiber; and (3) clothes, made by processing the fabric
