Beschreibung
Zusammenfassung:	The present invention relates to an extractable copolyester conjugate fiber in alkali solution. The conjugate fiber comprises: a first component comprising a copolyester resin; and a second component comprising an alkali-soluble copolyester resin. When the composite fiber is extracted with an aqueous alkali solution, it is possible to obtain a copolyester fiber having a uniform fine cross-section due to excellent extraction uniformity, and to manufacture a woven and knitted fabric comprising the same. 본 발명은 알칼리 용출형 코폴리에스테르 복합섬유에 관한 것으로써, 상기 복합섬유는 코폴리에스테르 수지를 포함하는 제1 성분; 및 알칼리 이용성 코폴리에스테르 수지를 포함하는 제2 성분;으로 구성되고, 상기 복합섬유를 알칼리 수용액으로 용출시 용출 균일도가 우수하여 균일한 세섬도 단면을 가지는 코폴리에스테르 섬유를 수득할 수 있으며, 이를 포함하는 직편물을 제조할 수 있다.
