Abstract

본 발명은 초고속방사법에 의한 폴리에스테르섬유의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester fiber by the ultra-fast spinning method.

종래의 초고속방사법은 가열기체공급부와 가열통이 연결되어 있기때문에 가열기체공급부에서 나온 기체가 사조에 수반하여 가열통으로 유입되었기 때문에 방사장력이 증가하였으며 방사조업성도 불량하였다.In the conventional ultra-high-speed spinning method, since the heating gas supply unit and the heating tube are connected, the radiation tension is increased because the gas from the heating gas supply unit is introduced into the heating tube along with the thread, and the radiation operation is poor.

본 발명은 가열기체공급부에서 나온 가열기체의 영향이 가열통에 미치지 못하도록 가열기체공급부와 가열통을 일정간격만큼 분리시켰으며, 또 가열기체결공급부를 사조고화점 직하 8~17cm의 지점에 위치시켜서 사조를 집속하고 예비열처리함을 특징으로 한다.The present invention separates the heating gas supply portion and the heating tube by a predetermined interval so that the influence of the heating gas from the heating gas supply portion does not reach the heating tube, and furthermore, the heating fastening supply portion is located at a point of 8 ~ 17cm directly below the Sajo solidification point. It is characterized by focusing and preheating.
