Abstract
본 발명은 고강력 저수축폴리에스테르섬유의 제조방법에 관한 것임.The present invention relates to a method for producing a high strength low shrinkage polyester fiber.
종래의 1단 또는 2단공정에 의한 산업용 폴리에스테르섬유의 제조방법은 고강력과 저수축성을 동시에 만족시키기가 어려웠으며 조업성이 불량하였다.In the conventional method for producing industrial polyester fiber by one or two stages, it is difficult to satisfy both high strength and low shrinkage at the same time and poor operation.
본 발명은 폴리에스테르 미연신사를 사용하여 횡연신방버으로 연산함에 있어서, 제1 고뎃롤러의 온도, 오븐온도, 연신장력 및 이완율과 이완장력을 적정조건으로 설정함으로서 조업성이 좋게 강도 8.0g/d이상, 건열수축율 2%미만, 신도 15~25%의 산업용 폴리에스테르섬유의 제조방법임.In the present invention, in calculating the transverse stretching chamber using polyester non-drawn yarn, by setting the temperature, the oven temperature, the stretching tension and the relaxation rate and the relaxation tension of the first gourd roller under appropriate conditions, the strength is 8.0g / d or more, less than 2% of dry heat shrinkage, and 15 ~ 25% elongation.
본 발명으로 제조된 폴리에스테르섬유는 타이어코드, 벨트등의 보강재로 사용된다.Polyester fiber produced by the present invention is used as a reinforcement material such as tire cords, belts.
