Abstract

본 발명은 디메틸테레프탈레이트에 대하여 이소프탈산 또는 디메틸이소프탈레이트를 10~15몰% 공중합시킨 폴리에스테르수지를 4,500~6,000m/분의 속도로 고속 방사함을 특징으로 하는 이염성 폴리에스테르 섬유의 제조방법에 관한 것으로, 본 발명에 의하여 제조된 섬유는 100℃이하 상압에서 염색할 경우에도 130℃의 온도에서 고압으로 염색한 일반 폴리에스테르섬유와 동등 또는 그 이상의 염색성을 나타내므로 고온, 고압에서는 손상을 쉽게 입는 섬유들, 즉 아세테이트, 레이온, 양모 및 나이론과의 교직 및 혼용이 가능한 장점이 있으며, 비용절감 측면에서도 유리하다.The present invention is a method for producing a dibasic polyester fiber characterized by spinning at a high speed of 4,500 ~ 6,000m / min polyester resin copolymerized with isophthalic acid or dimethyl isophthalate to dimethyl terephthalate at a speed of 4,500 ~ 6,000m / min. Regarding the fiber produced by the present invention, even when dyed at 100 ° C. or less at normal pressure, the fiber is dyed at a high pressure at 130 ° C., which is equivalent to or higher than that of general polyester fiber. The advantage of being able to blend and blend with fibers, such as acetate, rayon, wool and nylon, is advantageous in terms of cost reduction.
