The present invention provides a conjugated fiber that has excellent moisture-absorption properties, excellent antistatic properties, and excellent cool feeling by contact as well as being less prone to troubles in a post process even in the case where the fiber is interknitted with polyurethane or polyethylene terephthalate. The conjugated fiber is a core-sheath conjugated fiber, including: a core portion; and a sheath portion, wherein the core portion is not exposed through the surface of the core-sheath conjugated fiber, the core portion is composed of a polyether block amide copolymer represented by Formula (1), the polyether block amide copolymer having a hard segment (in the following formula) composed of nylon 6, the sheath portion is composed of a nylon-6 resin, and the area ratio of the core portion to the sheath portion in a transverse section of the core-sheath conjugated fiber is 3/1 to 1/5.
[In formula (1), PA represents a polyamide unit (hard segment) ; PE represents a polyether unit (soft segment); and n represents the number of repeating units.] |
