Abstract

저 데니어 폴리벤즈아졸 섬유를 기술하고 청구한다. 또한, 이러한 저 데니어Low denier polybenzazole fibers are described and claimed. Also, these low denier

폴리벤즈아졸 섬유의 제조방법을 청구한다. 본 방법은 섬유를 작은 오리피스(0.0051 내지 0.018㎝)를 통해 방사 연신비 12 내지 60으로 저농도 방사 도우프 밖으로 방사한 다음 섬유의 파단없이 750㎞이상으로 권취하는 것이다.Claims are made for producing a polybenzazole fiber. The method is to spin the fiber out of the low concentration spinning dope through a small orifice (0.0051 to 0.018 cm) at a spinning elongation ratio of 12 to 60 and then to wind it over 750 km without breaking the fiber.
