Abstract

Un procedimiento para preparar filamentos de polibenzazol, el cual incluye, extruir los filamentos a partir de una hilandera (1), que tiene por lo menos 100 agujeros, los cuales están dispuestos para formar un patron anular (2) alrededor del centro de la hilandera (1), el centro y por lo menos dos secciones radiales (3) de la hilandera (1) no teniendo ningun agujero, y una anchura promedio que es por lo menos 3 veces el paso mínimo de los agujeros, y estirar los filamentos a través de una cámara de extincion, mientras se provee un flujo de gas substancialmente radial en la misma a través de la hilandera (1) desde por lo menos dos diferentes direcciones.
