(57) [Summary] [Structure] A core-sheath type composite fiber having a thermoplastic resin as a core and a fiber-forming polyamide resin as a sheath, and the main component of the thermoplastic resin forming the core is polyether. It is an ester amide and the ratio of the core is 5 to 5 of the total weight of the composite fiber. A core-sheath type composite fiber having an excellent hygroscopicity of 0% by weight. [Effect] Since it has high hygroscopicity and good wearing comfort, it can be used as a comfortable material such as underwear and sportswear as a woven or knitted fabric. |
