폴리아마이드 멀티필라멘트사의 제조방법Manufacturing method of polyamide multifilament yarn

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (1)

고속방사법(방사속도 3,500m/분-4,200m/분)으로 제조한 폴리아마이드 멀티필라멘트 미연신사를 연신함에 있어서, 연신직전에 폴리머의 2차 전이온도보다 30℃-100℃의 높은 온도를 갖는 열수를 사조에 뭍힌 다음, 폴리머의 2차 전이온도보다 30℃-100℃의 높은 온도를 갖는 열로울러에 통과시켜 자연연신배율의 0.8배 이상의 연신배율로 열연신함을 특징으로 하는 폴리아마이드 멀티필라멘트사의 제조방법.In the stretching of polyamide multifilament unstretched yarn produced by the high-speed spinning method (spinning speed 3,500m / min-4,200m / min), hot water having a temperature of 30 ° C.-100 ° C. higher than the secondary transition temperature of the polymer immediately before stretching. The polyamide multifilament yarn, characterized in that the thermal stretching at a draw ratio of 0.8 times or more of the natural draw ratio by passing through a thermal roller having a temperature of 30 ℃ -100 ℃ higher than the secondary transition temperature of the polymer Way. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
