Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fiber in which the shedding of the moisture absorptive ingredient during dyeing is suppressed to a minimum, and the fiber has a good moisture absorptive and desorptive characteristic even after high-pressure dyeing.SOLUTION: Provided is a sea-island type composite fiber having a polyethylene terephthalate whose main repeating unit is ethylene terephthalate, as a sea portion, and a polyether block amide copolymer product as an island portion, and in which the sea/island cross-section area ratio is 30/70 to 95/5.SELECTED DRAWING: None 【課題】染色での吸湿成分の脱落を最小限に抑え、高圧染色後にも優れた吸放湿性および制電性を有する繊維を提供する。【解決手段】主たる繰り返し単位がエチレンテレフタレートであるポリエチレンテレフタレートを海部とし、ポリエーテルブロックアミド共重合物島部とし、海／島横断面積比率が３０／７０〜９５／５の海島型複合繊維である。【選択図】なし
