▎ 摘  要

NOVELTY - Preparing graphene anti-ultraviolet regenerated fiber, comprises (1) taking each raw material according to the ratio; (2) pre-mixing dried recycled polyethylene terephthalate slice with graphene material, and adding coupling agent in pre-mixing stage; (3) mixing premix by a mixer, and granulating by a double-screw extruder to obtain graphene recycled polyethylene terephthalate master batch; (4) using graphene recycled polyethylene terephthalate master batch for melt spinning to obtain graphene recycled polyethylene terephthalate composite fiber; and (5) crisscrossing and blending graphene recycled polyethylene terephthalate composite fiber with other fibers to obtain graphene anti-ultraviolet fabric. USE - The method is useful for preparing graphene anti-ultraviolet regenerated fiber. ADVANTAGE - The fabric effectively prevents ultraviolet rays for a long time, and is not affected by the number of washings.
