▎ 摘　　要

NOVELTY - Preparing graphene composite polyester hollow fiber film involves mixing graphene powder with polyester powder and adding into screw extruder to obtain graphene composite polyester master batch. The graphene composite polyester master batch and blank polyester slice are added into the spinning machine to obtain the graphene composite polyester fiber. The graphene composite polyester fiber is woven into hollow tubular to obtain hollow fiber lining pipe. The hollow fiber lining pipe is prepared into the surface additive. The poly tetrafluoroethylene hollow fiber film casting film liquid is prepared using the spinning device, uniformly coated the polytetrafluoroethylene casting solution on the graphene polyester inner liner tube to obtain graphene polyester hollow fiber film. The graphene polyester hollow fiber film into the solvent groove. The graphene polyester hollow fiber film is continuously pulled, and soaked in the water tank, removed the redundant solvent. USE - Method for preparing graphene composite polyester hollow fiber film. ADVANTAGE - The method enables to prepare graphene composite polyester hollow fiber film with excellent mechanical strength, water pressure resistance and antibacterial performance.
