▎ 摘　　要

NOVELTY - Producing copolymer aramid fiber, comprises (i) adding graphene, graphene oxide or mixture of graphene and graphene oxide into an organic solvent, and dispersing, (ii) adding an aromatic diimine into the dispersed organic solvent, and dissolving the aromatic diamine, (iii) adding terephthaloyl dichloride in the organic solvent, and reacting to produce polymer solution containing aramid copolymer, and (iv) spinning the polymer solution, solidifying and heating. USE - The method is useful for producing copolymer aramid fibers (claimed). ADVANTAGE - The copolymer aramid fibers have excellent compatibility and dispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for copolymer aramid fibers produced by the above method, containing graphene, graphene oxide or mixture of graphene and graphene oxide on fibers, and having intensity of 30-35 g/d.
