RESEARCH PROGRESS ON GRAFT MODIFIED POLYACRYLONITRILE FIBER
The main methods of chemical grafting modification of polyacrylonitrile fibers are summa-rized,and the problems of poor mechanical properties and low utilization rate of modified fibers are e-laborated and analyzed.It is pointed out that the main direction for its future development is to adopt mild chemical modification methods and expand the application fields of large-scale modified fibers.
