Document Type and Number:
WIPO Patent Application WO/2023/100570
Kind Code:
A1
Abstract:
The present invention provides an eccentric core-sheath composite false twisted yarn which is characterized in that: in a cross-section of a composite fiber which is composed of two different polymers that are an A-component and a B-component, the A-component is completely covered by the B-component; the ratio S/D of the minimum thickness S of the thickness of the B-component covering the A-component to the fiber diameter D is 0.01 to 0.1; the length of the periphery of a fiber portion where the thickness is not more than 1.05 times the minimum thickness S is not less than one third of the length of the periphery of the whole fiber; the difference of modification degree among single yarns is 0.2 or more; and the crimp ratio of 30% or more.
