The present invention relates to a polyethylene terephthalate (PET) cord and a manufacturing method thereof. The PET tire cord with a low creep ratio is provided by inducing crystallization directly under a nozzle by increasing spin draft, and increasing time and temperature for heat set at a high temperature in a godet roller.
폴리에틸렌테레프탈레이트(PET) 코드 및 그 제조방법에 관한 것으로, 스핀드래프트를 높여 노즐 직하부에서 결정화를 유도하고, 고뎃롤러(Godet roller)에서 고온으로 heat set 하는 시간과 온도를 높여 크리프율이 낮은 폴리에틸렌테레프탈레이트(PET) 타이어 코드를 제공한다.
