▎ 摘　　要

NOVELTY - Graphene modified polypropylene coarse fiber comprises skin layer and core layer. The core layer is covered in skin layer. The core layer is polyoxymethylene. The skin layer comprises 50-250 pts. wt. polypropylene resin, 0.5-5 pts. wt. graphene, 1-10 ps. wt. polyvinylpyrrolidone, 0.1-1 pt. wt. liquid paraffin, 1-15 pts. wt. wollastonite powder, 0.1-0.5 pt. wt. antioxidant and 0.1-0.5 pt. wt. UV absorber. USE - Graphene modified polypropylene coarse fiber. ADVANTAGE - The fiber has good graphene dispersion and high fiber strength.
