Abstract:
This paper reviewed the progress of the aramid fibers and the market demand and the the necessity of aramid fiber in China .the related preparation technology and study methods are introduced.: progress of aramid polymer polymerization methods , the processability of polymer and the comprehensive performance of fiber were improved through the introduction of new polymerization monomer to copolymerization , aramid fiber filament, short-fiber and plasma pulp fiber spinning technology were mentioned , the anionzation of PPTA resin alkylation technology and its application, The surface treatment and modification of the research including surface coating, high-energy rays, plasma processing of physical method and through the surface activeness, surface chemical graft method of aramid fiber were referred , The focus on new technology synchrotron radiation observed aramid fiber structure..With consideration of practical situation in China, Authors give some proposals for the domestic Aramid fiber industry, including strengthening fundamental research for a leapfrog development, deepening cross-subject cooperation and integration of key equipment, enhancing the application of Aramid fiber domestically, tightening control over production power, etc.
