Abstract

본 발명은 산업용 원사, 즉 타이어, 벨트 등 고무 복합재료의 보강재료로서 널리 사용되는 폴리에스터 섬유의 제조방법에 관한 것으로, 특히 연신 영역에 고열의 유체를 이용하여 순간적으로 가열하는 방법에 의해 연신 안정성을 향상시켜 고강력 산업용 원사를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a polyester fiber widely used as a reinforcing material for rubber composite materials such as tires, belts, and the like, in particular, stretching stability by a method of instantaneous heating using a high-temperature fluid in the drawing area. It relates to a method of manufacturing high strength industrial yarn by improving the.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (3)

강도 8.5g/d 이상, 건열수축율(177℃×5분) 3% 이하, 복굴절율 0.15~0.20, 비정배향지수 0.45~0.55, 장주기 120~160A인 것을 특징으로 하는 폴리에스터 섬유.A polyester fiber characterized in that the strength is 8.5g / d or more, dry heat shrinkage (177 ℃ × 5 minutes) 3% or less, birefringence 0.15 ~ 0.20, non-orientation index 0.45 ~ 0.55, long cycle 120 ~ 160A. 폴리에틸렌테레프탈레이트를 주반복단위로 하는 폴리에스터를 용융방사, 연신하여 폴리에스터 섬유를 제조함에 있어서, 연신공정중 예비연신부에서 1.01~1.03배 연신하고 연신점 고정장치의 온도를 Tg+50℃~Tg+100℃로 하고, 주연신부에서 2.0~3.0배 연신하고 연신점 고정장치의 온도를 Tg+100℃~Tg+250℃로 하는 것을 특징으로 하는 폴리에스터 섬유의 제조방법(단, Tg는 폴리에스터의 유리전이온도).In manufacturing polyester fiber by melt spinning and stretching a polyester having a polyethylene terephthalate as a main repeating unit, the stretching is carried out 1.01 to 1.03 times in the preliminary stretching portion during the stretching process and the temperature of the stretching point fixing device is Tg + 50 ° C. A method for producing a polyester fiber, characterized in that the Tg + 100 ℃, stretched 2.0 to 3.0 times in the main stretching portion and the temperature of the stretching point fixing device is Tg + 100 ℃ ~ Tg + 250 ℃ (where Tg is poly Glass transition temperature of the ester). 제2항에 있어서, 예비연신부에서는 가열공기를 사용하고 주연신부에서는 가열스팀을 사용하는 것을 특징으로 하는 폴리에스터 섬유의 제조방법.The method of claim 2, wherein the pre-stretched portion uses heated air and the main stretch portion uses heated steam. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
