ABSTRACT:
A method for fibrillating carbonaceous fibers, which comprises contacting a tow of carbonaceous fibers to rotating surfaces of rollers for fibrillation, wherein at least two rollers are disposed so that the center axes of the rollers intersect the direction of advance of the tow of carbonaceous fibers and the rotating surfaces of the rollers are substantially alternately inclined in opposite directions, thereby to exert a shearing force to the tow in a direction transverse to the direction of advance of the tow.
