ABSTRACT:
Crimped polybenzazole staple fibers which satisfy the following specifications at the same time:
(1) 2.ltoreq.number of crimps (number/inch).ltoreq.40
(2) 2.ltoreq.crimp index (%).ltoreq.30
(3) 0.3.ltoreq.crimp index
umber of crimps.ltoreq.3.0; methods for manufacturing crimped polybenzazole staple fibers; and the rotary cutter therefor. The crimped polybenzazole staple fibers of the present invention are superior in crimp property and are useful for manufacturing spun yarn and unwoven fabric. According to the method of the present invention, crimped polybenzazole staple fibers superior in spinnability can be manufactured with ease. In addition, the cutting blade of the present invention stands a long time use for manufacturing staple fibers from a continuous filaments tow of high tenacity fibers.
