Abstract

본 발명은 저분자량의 폴리에스테르계 올리고머와 고분자량의 폴리에스테르계 수지를 방사공정중에서 혼합, 방사하여 섬유의 표면에 무수히 많은 미세공이 분포되게 함으로써 심색성이 우수한 폴리에스테르 섬유를 제조하는 방법에 관한 것으로써, 더욱 상세하게는 섬유의 알칼리 처리공정중에서 쉽게 용출될 수 있는 성분으로 저분자량의 폴리에스테르계 올리고머를 방사공정중에서 기존 섬유 형성용 폴리에스테르 수지와 혼합하여 방사함으로써 방사작업성이 우수할 뿐 아니라 제조된 섬유가 알칼리 감량 공정을 통하여 표면에 무수히 많은 미세공이 형성됨으로써 염색후에 심색성 및 선명성이 일반 폴리에스테르에 비해 월등히 향상되고 또한 섬유를 제조하기 위한 작업성이 안정됨으로서 생산성을 향상시킬 수 있는 심색성이 우수한 섬유의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester fiber having excellent cardiovascular properties by mixing and spinning a polyester oligomer having a low molecular weight and a polyester resin having a high molecular weight in a spinning process to distribute innumerable fine pores on the surface of the fiber More specifically, a low molecular weight polyester oligomer is easily mixed with a polyester resin for forming a fiber in a spinning process as an ingredient that can be easily eluted in an alkali treatment process of a fiber, Since the number of fine pores is formed on the surface through the alkali weight reduction process of the manufactured fiber, the carding property and the sharpness after dyeing are significantly improved as compared with the ordinary polyester, and the workability for producing the fiber is stable, Fiber fabrics with excellent coloration It relates to a method.
