Abstract

본 발명은 단사섬도 1 데니어 이하이고 단사수가 70 이상인 폴리에스터 극세멀티필라멘트사를 방사속도 5,500m/분 이상의 초고속방사 공법으로 제조함에 있어서, 방사구금을 제외한 방사팩 하부와 방사구금 직하로부터 30∼100mm가 되는 위치의 방출사조 주위를 하나의 가열장치로 가열시키는 것을 특징으로 하는 폴리에스터 극세멀티필라멘트사의 제조방법을 제공하는 것으로, 본 발명의 방법에 따르면, 사의 균제도가 양호하고 사절이 방지되어 작업성이 향상되므로 인취 로울러나 별도의 열처리 장치 등에 의한 섬유의 연신없이 방사공정만의 공정으로 폴리에스터 극세멀티필라멘트사를 초고속방사공정에 의하여 안정적으로 제조할 수 있다.In the present invention, the ultrafine multifilament yarn having a single yarn fineness of 1 denier or less and a single yarn number of 70 or more is manufactured by an ultra-fast spinning method having a spinning speed of 5,500 m / min or more, and 30 to 100 mm from the bottom of the spin pack except for spinnerets and directly below the spinnerets. To provide a method for producing a polyester ultra-multifilament yarn, characterized in that the heating around the discharge yarn at a position to be a single heating device, according to the method of the present invention, the uniformity of the yarn is good and the trimming is prevented workability Therefore, it is possible to stably manufacture the polyester ultra-multifilament yarns by the ultra-fast spinning process by the spinning process only, without drawing fibers by a draw roller or a separate heat treatment apparatus.
