▎ 摘　　要

NOVELTY - Preparing low temperature resistant graphene polyester filament, comprises (i) mixing the polyester chips and the binder into a slurry, removing the moisture, and forming a spinning mucilage; (ii) extruding the spinning mucus from a spinneret to form a fiber tow by melt spinning; (iii) under high temperature conditions, coagulating the fiber tow and reinforcing agent, regenerating, washing and drying. USE - The method is useful for preparing low temperature resistant graphene polyester filament. ADVANTAGE - The low temperature fiber has stable quality, cold resistance, good toughness, good waterproof performance, can keep good softness under the condition of low temperature, is not easy to be broken, and has increased service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for low temperature resistant graphene polyester filament.
