Abstract (en)
A process for producing non-woven fabrics having a high bulk density, uniform porosity and little characteristic of so-called interlayer detachment are provided by subjecting an infusiblized sheet of pitch fibers to a heat treatment at a temperature higher than the softening temperature of the pitch fibers and lower than the softening temperature plus 300 DEG C, while applying a pressure to the surface of said sheet substantially in the vertical direction thereof.
