MOISTURE-ABSORBING BULKY ELASTIC YARN AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a moisture-absorbing bulky elastic yarn preventing grin-through caused by stretching/shrinking, wetting and the like and suitable for being used as a fabric for clothing having adaptability to quick sweating of human body accompanied by exercise and comfortableness in exercise and a method for producing the same. SOLUTION: The moisture-absorbing bulky elastic yarn is prepared by coating a polyester elastic yarn with 2 or more species of crimped yarns comprising a thermoplastic synthetic yarn. The polyester yarn is the moisture-absorbing elastic yarn and the 2 or more species of the crimped yarns are different in length and elongation at break. The method for producing the moisture-absorbing bulky elastic yarn is efficiently produced by simultaneously fiber-mixing and/or interlacing the moisture-absorbing polyester under tension with 2 or more species of the thermoplastic synthetic yarns having difference in elongation and simultaneously processing by drawing and false twisting the yarns.
