Abstract

본 발명은 테레프탈산과 에틸렌글리콜을 사용하여 통상의 폴리에스테르 축중합후 고상중합시킨 용융점도 2600∼2800포아즈이고 고유점도가 0.8∼0.8이/g이며, 카르복실 말단기가 20∼25eq/106g인 내알칼리 가수분해성 섬유형성성 중합물을 도성분으로 하고, 방향족 디카르복실산 또는 이의 에스테르 생성 유도체로 조성되는 산성분과 두개 또는 그 이상의 탄소원자를 갖는 1종 이상의 알킬렌글리콜 또는 이의 에스테르 생성 유도체로 구성되는 글리콜 부위로 중합시 하기 일반식(I)의 화합물을 전산성분에 대하여 0.8∼20몰% 첨가하고, 하기 일반식(II)의 화합물을 변성 폴리에스테르의 전중량 대비 0.5∼20중량% 첨가하여 중합한 변성 폴리에스터를 해성분으로 하여 복합방사하는 것을 특징으로 하는 폴리에스터계 해도형 복합섬유의 제조방법을 제공하는 것으로, 본 발명에 의하면 용출성분의 제거속도가 빠를 뿐만 아니라 방사성 및 연신성이 향상되고, 더욱이 알칼리 용출처리시 비용출성분의 침해가 최소화되어 본 발명에 의해 수득되는 해도형 복합섬유는 제품성이 우수한 이점을 갖는다.The present invention has a melt viscosity of 2600 to 2800 poise, solid phase polymerization after conventional polyester condensation polymerization using terephthalic acid and ethylene glycol, intrinsic viscosity of 0.8 to 0.8 / g, and 20 to 25 eq / 10 6 g of carboxyl terminal groups. Phosphorus alkali-hydrolysable fiber-forming polymer as a component and composed of one or more alkylene glycols or ester-forming derivatives thereof having an acidic component composed of aromatic dicarboxylic acid or ester-forming derivative thereof and two or more carbon atoms When the polymerization is performed at the glycol site, 0.8 to 20 mol% of the compound of formula (I) is added to the acid component, and 0.5 to 20 wt% of the compound of formula (II) is added to the total weight of the modified polyester. To provide a method for producing a polyester-based islands-in-the-sea composite fiber characterized in that the composite spun by polymerized modified polyester as a sea component. According to the present invention, the removal rate of the elution component is not only fast but also improves the radioactivity and elongation, and furthermore, the island-in-the-sea composite fiber obtained by the present invention is minimized in the infiltration of the elution component during the alkali elution treatment, and thus the product quality is excellent. Has an advantage.
