Abstract
본 발명은 합성섬유 극세사를 제조하기 위해 알칼리 수용액에 쉽게 가수분해되는 변성폴리에스터를 제조하는 방법에 관한 것으로, 하기 일반식(Ⅰ)의 나트륨술포네이트기를 함유한 알킬 성분이 전체 변성 폴리에스터에 대하여 3~20중량%가 되도록 혼합 반응시켜 변성 폴리에스터를 수득하는 것을 특징으로 하는 변성 폴리에스터의 제조방법이며, 본 발명에 의하여 수득된 변성 폴리에스터를 사용하면 방사 공정중의 생산성 및 수득하는 원자의 물성이 향상되는 잇점이 있다.The present invention relates to a method for producing a modified polyester which is easily hydrolyzed in an aqueous alkali solution to prepare a synthetic fiber microfiber, wherein the alkyl component containing sodium sulfonate group of the general formula (I) It is a method for producing a modified polyester, characterized in that the mixed polyester to react to 3 to 20% by weight to obtain a modified polyester, by using the modified polyester obtained by the present invention the productivity of the spinning process and the resulting atoms There is an advantage that the physical properties are improved.
