Title:
CRIMPED COMPOSITE FIBER, AND FIBROUS MASS AND TEXTILE PRODUCT USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/007875
Kind Code:
A1
Abstract:
Disclosed is a crimped composite fiber that comprises a first component and a second component; wherein the abovementioned first component comprises polybutene-1 and linear low-density polyethylene, the amount of linear low-density polyethylene comprised is 2-25% by mass, the abovementioned second component comprises a polymer with a peak melting temperature that is at least 20°C higher than the peak melting temperature of the polybutene-1 or a polymer with a melting initiation temperature of at least 120°C, the abovementioned first component occupies at least 20% of the surface of the composite fiber (10) when viewed from a fiber cross-section, the center of gravity of the abovementioned second component is offset from the center of gravity of the abovementioned composite fiber, and the abovementioned composite fiber is a manifested crimp exhibiting three-dimensional crimps, or is a potential crimp that will exhibit three-dimensional crimps by means of heating. As a result, crimped composite fibers, which having strong elasticity, volume recovery, and resistance in repeated compression, as well as strong elasticity, volume recovery, and resistance when being used under high heat conditions, and a fibrous mass using the same can be provided.
