Title:
FIBER BUNDLE AND FALSE TWISTED YARN, WOVEN KNITTED ITEM, AND CLOTHING CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2016/133196
Kind Code:
A1
Abstract:
Provided is a hollow polyester multifilament that has a polygonal cross-sectional shape; in which a single fiber has a rectangular to octagonal cross-sectional shape; that has a single hollow section; and in which single fibers having a right-hexagonal cross-sectional shape preferably account for 70 % or greater of the total number of fibers in the lateral cross-section of the multifilament. In addition to the see-through prevention due to refraction of light at the fiber surfaces, the thermal insulation performance is increased because it is possible to load the fibers at the greatest density, the fiber weight is reduced due to having the hollow section, and, in the case in which the hollow section has a circular shape, light is randomly refracted, thus, achieving a greater see-through prevention. Also, when used as a textured yarn in a woven knitted item, weight reduction, excellent thermal insulation, a light blocking effect, and see-through prevention are strongly exhibited.
