Abstract

The present invention provides novel conjugate fibers being excellent in productivity and having good water absorption, antistatic property and cool feeling by contact. The conjugate fibers include a fiber-forming resin such as polyamide, polyester and the like in the sheath portion and a polyether block amide copolymer in the core portion, in which the area ratio of the core portion to the sheath portion is 5/95 to 95/5, and the exposure angle of the core portion to the surface is 5° to 90°. Specifically it is preferable that the area ratio of the core portion to the sheath portion is 10/90 to 90/10, the exposure angle of the core portion to the surface is 5° to 80°, and the crimp ratio is 2 to 30%.
