▎ 摘　　要

NOVELTY - Graphene composition para-aramid fiber, comprises graphite-based material, and polyparaphenylene terephthalamide, graphene composition of para-aramid fiber, and content of the graphite-based material is less than 5 wt.%, preferably, 0.5-3 wt.%, and more preferably, 1-2.5 wt.%. USE - The graphene composition para-aramid fiber is useful as bullet-proof vests, helmet, aerospace materials, tire frame material, as well as in the universe to explore, aerospace, defense industry, water and land transportation, rope cable, sports and leisure as a reinforcement (claimed). ADVANTAGE - The para-aramid fiber has high-performance; has good tensile strength; improves quality endowed with para-aramid fiber material in excellent antibacterial property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing para-aramid fiber, comprising (a) mixing graphene and concentrated sulfuric acid solution, to obtain a graphene solution, preprocessing, to obtain a graphene classifier solution. or preparing graphene material directly into a graphene solution for pretreatment, filtering and drying with concentrated sulfuric acid, to obtain graphene grading solution; (b) mixing the polyparaphenylene terephthalamide with the graphene grading solution, to obtain a spinning dope; and (c) filtering spinning dope, defoaming, after spinning and drying.
