Description

폴리에스터 스핀드로우 얀의 제조 방법Process for producing polyester spin draw yarn

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

제1도는 종래 기술의 연신사 제조장치 개략도,1 is a schematic drawing of a drawing machine of the prior art;

제2도는 본 발명의 연신사 제조장치 개략도.2 is a schematic view of a drawing yarn manufacturing apparatus of the present invention.

Claims (4)

제2도와 같이 4개의 고뎃로울러를 사용하는 폴리에스터 연신사의 제조방법에 있어서, 방사된 실을 폴리에스터의 2차 전이온도 이하인 70∼80℃의 제1고뎃로울러 (2) 및 제2고뎃로울러(3)사이를 통과하는 동안 미연신사에 에이징을 행하고, 속도가 다르고 온도가 80∼90℃인 제3고뎃로울러(4)를 통과하는 사이 약연신됨과 동시에 내부 응력을 발생시키고 110∼130℃인 제4고뎃로울러 (5)를 통과하는 동안 강제연신되나 제3고뎃로울러 (4)에서 발생된 내부응력의 영향으로 연신 정도가 하향조정되어 안정한 연신성을 부여한 후 권취함을 특징으로 하는 폴리에스티 스핀 드로우 얀의 제조방법.In the manufacturing method of the polyester drawn yarn using four high rollers as shown in FIG. 2, the first yarn roller (2) and the second roller roller of 70 to 80 ° C. which are less than or equal to the secondary transition temperature of the polyester 3) Aging is performed to the undrawn yarn during the passage, and is weakly drawn while passing through the third high roller (4) having a different speed and temperature of 80 to 90 ° C, and at the same time, generates internal stress and generates 110 to 130 ° C. Polyester spin draw, characterized in that it is forcedly stretched while passing through the four rollers (5), but the drawing degree is adjusted downward by the influence of the internal stress generated in the third roller (4) to impart stable stretchability. Method of Making Yarn. 제1항에 있어서, 제1 고뎃로울러(2)와 제2 고뎃로울러(3)는 로울러의 속도와 온도가 동일함을 특징으로 하는 폴리에스터 스핀 드로우 얀의 제조방법.The method of claim 1, wherein the first roller roller (2) and the second roller roller (3) is the same speed and temperature of the roller. 제1항에 있어서, 제3 고뎃로울러(4)의 속도는 제2 고뎃로울러(3)보다 1.5배 빠른 것을 특징으로 하는 폴리에스터 스핀 드로우 얀의 제조방법.The method of claim 1 wherein the speed of the third high roller (4) is 1.5 times faster than the second high roller (3). 제1항에 있어서, 제4 고뎃로울러(5)의 속도는 제3 고뎃로울러(4)보다 2.5∼2.7배 빠른 것을 특징으로 하는 폴리에스터 스핀 드로우 얀의 제조방법.The method of claim 1 wherein the speed of the fourth high roller (5) is 2.5 to 2.7 times faster than the third high roller (4). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
