Title:
STRETCH-PROCESSED YARN, FIBER PRODUCT, COMPOSITE SPINNERET, AND COMPOSITE FIBER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/095861
Kind Code:
A8
Abstract:
The present invention provides a stretch-processed yarn that can be formed as a fiber material, which has motion followability as a result of favorable stretching properties and appropriate resistance when elongated and a soft surface feel that corresponds to a crimped structure. This stretch-processed yarn comprises a multifilament obtained from fibers with a coiled crimped structure in the axial direction of the fiber. The distribution of crimp coil diameters in said fiber has at least two groups. The ratio of the average value for the group with the largest coil diameter to the average value for the group with the smallest coil diameter (average value for group with largest diameter/average value for group with smallest diameter) is less than 3.00 and the cross-sections of the fibers constituting the multifilament are eccentric core-sheath cross-sections.
