| titleOfInvention | Hygroscopic crimped composite fiber |
| abstract | An object of the present invention is to provide a raw yarn for a fabric having a breathable self-adjusting function and a moisture-permeable and waterproof function by causing crimps to appear when moisture is absorbed and shrinking an apparent yarn length, and a method for producing the same. SOLUTION: A composite fiber in which a polyamide component and a polyester component are bonded in a side-by-side type, wherein the polyester component occupies 60 to 99.5 mol% of repeating units, and the ethylene terephthalate unit occupies 0.5 to 40 mol. % Is a copolymer polyester in which ethylene isophthalate units occupy 5 to 55% by weight of a specific polyetheresteramide in the polyester component, and the composite fiber is treated with boiling water for 30 minutes, followed by dry heat treatment at 100 ° C. The crimp ratio DC of the composite fiber that has been crimped and has been crimped and then heat-treated at 160 ° C. is 0.2 to 3.0%, and the crimp ratio HC after the composite fiber is immersed in water is A composite fiber having a crimp rate of 0.5 to 7.0% and a difference ΔC of 0.5 to 6.0% in the following formula. ΔC (%) = HC (%) − DC (%) [Selection figure] None |
