Description
一方、本件第2発明の基本構成は、複合紡糸にて、鞘部が、主たる繰り返し単位がポリエチレンテレフタレートから構成され、ジカルボン酸成分として5−ナトリウムスルホイソフタル酸が1.0〜3.0mol%、及びアジピン酸が3.0〜10.0mol%共重合された変性ポリエステルを配し、芯部にポリアミドを配した単繊維繊度が0.5〜2.0dtexである芯鞘型のカチオン可染性複合繊維の製造方法であって、前記ポリアミドが、高分子量型ヒンダードアミン系安定剤を0.3〜5.0質量%含有すること、前記カチオン可染性複合繊維からなる未延伸糸を、第1段延伸域において1倍を越え、1.2倍未満の延伸倍率にて加熱延伸すること、及び次いで第2段延伸域において、70℃のときの最大延伸倍率を0.6倍を越え、0.8倍未満として延伸し熱セットすること、を含んでいる。 On the other hand, the basic structure of the second invention of the present invention is a composite spinning, in which the sheath part is composed of polyethylene terephthalate as a main repeating unit, and 5-sodium sulfoisophthalic acid is 1.0 to 3.0 mol% as a dicarboxylic acid component, And a core-sheath type cation dyeable dye having a monofilament fineness of 0.5 to 2.0 dtex in which a modified polyester in which 3.0 to 10.0 mol% of adipic acid is copolymerized is disposed and polyamide is disposed in the core. A method for producing a composite fiber, wherein the polyamide contains 0.3 to 5.0% by mass of a high-molecular-weight hindered amine stabilizer, and an undrawn yarn made of the cationic dyeable composite fiber, Heat-draw at a draw ratio of more than 1 and less than 1.2 times in the step-drawing zone, and then, in the second-stage draw zone, the maximum draw ratio at 70 ° C. exceeds 0.6 times. Includes, to heat-set and stretched as less than 0.8 times.
