Abstract

Un procedimiento continuo para preparar fibras cortas de polibenzazol que comprende suministrar el polímero de polibenzazol a través de un extrusor (1) hacia una cabeza giratoria (2) para girado, pasando los filamentos a través de una cámara de extincion (3), alrededor de rodillos (4) y a través de un dispositivo de corte (5) el cual corta los filamentos en fibras cortas.
