The present invention relates to a polyethylene terephthalate (PET) cord and a method for manufacturing the same. The crystallization is induced at a direct bottom of a nozzle by raising a spin draft, and heat set of a Godet roller is set to a high temperature, thereby providing a PET cord having low elongation change rate and having a low strength change rate after a high temperature tensile test.
폴리에틸렌테레프탈레이트(PET) 코드 및 그 제조방법에 관한 것으로, 스핀드래프트를 높여 노즐 직하부에서 결정화를 유도하고, Godet roller에서 고온으로 heat set 하여 중신변화율이 낮고, 고온인장시험 후에 코드의 강력변화율이 적은 PET코드를 제공 한다.
DIMENSIONALLY STABLE POLYETHYLENETEREPHTHALATE TIRE CORD METHOD OF MANUFACTURING THE SAME AND TIRE INCLUDING THE SAME
형태안정성이 우수한 폴리에틸렌테레프탈레이트 타이어 코드, 이의 제조방법 및 이를 포함하는 타이어
