▎ 摘　　要

NOVELTY - Preparing a polyethylene terephthalate (PET)-based graphene conductive fiber, comprises: (1) providing a graphene/PET conductive master batch and PET chips with a natural color, where water contents of the graphene/PET conductive master batch and the PET chips with a natural color are lower than 30 ppm; (2) carrying out melt blending on the graphene/PET conductive master batch and the PET chips with a natural color by using a three-dimensional efficient dynamic mixer, and feeding a mixture into a twin-screw extruder to obtain a nascent PET-based graphene fiber; and (3) carrying out drawing and heat setting on the nascent PET-based graphene fiber to obtain a PET-based graphene conductive fiber. USE - The method is useful for preparing PET-based graphene conductive fiber for preparing textile raw materials or products (claimed). ADVANTAGE - The method is simple and rapid and good in compatibility with conventional packaged technologies and equipment and the prepared PET-based graphene conductive fiber can be applied to the field of functional textiles with electric conduction and electrostatic resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a PET-based graphene conductive fiber prepared by using the method.
