Abstract

본 발명은 파단강도 9.5g/d 이상, 파단신도 15∼25%, 강인성 30이상이고, 175℃에서의 건열수축율이 2%이하인 고강도, 저수축 폴리에스테르 섬유로서 타이어등 산업용자재에 적합한 섬유이다.The present invention is a high strength, low shrinkage polyester fiber having a breaking strength of at least 9.5 g / d, an elongation at break of 15 to 25%, and a toughness of 30 or more, and a dry heat shrinkage at 175 ° C of 2% or less, which is suitable for tires and other industrial materials.

본 발명은 또 복굴절율이 0.02 이하이고 단사면적의 최대치와 최소치와의 비가 1.5이하인 폴리에스테르 미연신사를 만들고, 상기 미연신사를 사용하여 횡연신(Warper-draw)법으로 총연신비 3.5∼6.5배가 되게 다단으로 연신하고, 열처리, 이완시켜서 제조하는 고강도, 저수축 폴리에스테르 섬유의 제조방법이다.The present invention also makes a polyester non-drawn yarn having a birefringence of 0.02 or less and a ratio between the maximum value and the minimum value of the single yarn area of 1.5 or less, and the total draw ratio is 3.5 to 6.5 times by the warp-draw method using the non-drawn yarn. It is a manufacturing method of high strength, low shrinkage polyester fiber manufactured by extending | stretching in multiple stages, heat processing, and relaxing.
