Abstract

필라멘트로 토우를 제조하고 이를 완축하여 커팅하는 소위 토우-투-톱(Two-To-Top) 공정으로 방향족 폴리아미드 스테이플을 제조함에 있어서 완축수가 많을수록 토우 중의 필라멘트 절사 현상이 자주 발생한다.In the production of aromatic polyamide staples in a so-called two-to-top process in which a tow is manufactured by filament and then shrunk and cut, filament cutting in the tow occurs more frequently.

이 발명에서는 필라멘트에서의 완축수를 인치당 10개 미만으로 줄이고 스테이플의 길이와 완축수의 비를 3.3 이상으로 하여 폴리아미드 스테이플 제조 공정을 개선하였다.In the present invention, the number of shrinkages in the filament is reduced to less than 10 per inch, and the ratio of the length of the staples and the number of shrinkages to 3.3 or more improves the polyamide staple manufacturing process.
