Title:
POLYESTER MULTIFILAMENT BLENDED YARN, FABRIC, METHOD FOR MANUFACTURING POLYESTER MULTIFILAMENT BLENDED YARN, AND METHOD FOR MANUFACTURING FABRIC
Document Type and Number:
WIPO Patent Application WO/2021/085353
Kind Code:
A1
Abstract:
Provided is a polyester multifilament blended yarn that can exhibit a sense of bulkiness and softness like that of natural fibers. Also provided are a fabric, a method for manufacturing the polyester multifilament blended yarn, and a method for manufacturing the fabric. In a polyester multifilament blended yarn 1 obtained by interlacing at least two types of polyester multifilament yarns having different thermal shrinkage rates, the two types of polyester multifilament yarns include a false-twisted yarn 10 and a partially-drawn yarn 20, and both yarns are subjected to dry thermal shrinkage. Although large shrinkage occurs overall through thermal shrinkage, locations with different shrinkage amounts are mixedly present on a localized manner, and both yarns are unevenly exposed to the outside. Unevenness in the dyeing degree attributed to the differences in the shrinkage amounts in the longitudinal direction of the blended yarn, and unevenness in the dyeing degree attributed to differences in the degrees of orientation of both yarns are combined, and thereby a sense of uneven rippling is formed in the longitudinal direction of the blended yarn after dyeing, and color tones and textures like those of natural fibers are exhibited in the fabric.
