Method for improving filament cohesiveness of chopped aramid fiber |
摘要 |
The invention pertains to a method for improving filament cohesiveness of chopped aramid fiber including the steps of impregnating a film-forming binding agent into the fiber, drying the fiber, optionally applying a finish to the fiber, and chopping the fiber to pieces of 1 to 16 mm length, characterized in that the fiber prior to applying the binding agent is subjected to a twisting process to obtain a fiber having a twisting level of 10 to 150 tpm and that the chopping of the fiber is performed in a rotary chopper. |
