Abstract

본 발명은 분자쇄의 전반복단위중 90몰% 이상이 폴리테트라메틸렌아디프아미드로 이루어져 있고, 상대점도가 4.0이상인 나일론46 중합체를 방사온도 290∼310℃, 방사속도 400∼700m/분으로 방사한 후 길이가 200∼400mm이고, 온도가 300℃ 이상인 가열통에 통과시키고 냉각온도가 20~50℃이고 냉각속도가 0.2m/분 이하인 냉각장치에서 냉각한 후 5.0배 이상으로 연신하여 권취함을 특징으로 하는 강력이 우수한 나일론46 섬유의 제조방법이다.In the present invention, at least 90 mol% of the first half of the molecular chain is composed of polytetramethyleneadipamide, and the nylon 46 polymer having a relative viscosity of 4.0 or more is spun at a spinning temperature of 290 to 310 ° C and a spinning speed of 400 to 700 m / min. After passing through a heating tube with a length of 200 ~ 400mm and a temperature of 300 ℃ or more, cooling in a cooling device with a cooling temperature of 20 ~ 50 ℃ and a cooling rate of 0.2m / min or less, stretching it by 5.0 times or more It is a method of producing a nylon 46 fiber having excellent strength.
