Title:

THERMO-FUSIBLE CONJUGATE FIBERS AND METHOD FOR PRODUCING SAME, AND NONWOVEN FABRIC USING SAME

Document Type and Number:

WIPO Patent Application WO/2017/208967

Kind Code:

A1

Abstract:

An object of the invention is to provide thermo-fusible conjugate fibers having a high degree of crystallinity, while a degree of orientation is suppressed, and a bulky and soft nonwoven fabric using the same.　 The thermo-fusible conjugate fibers of the invention have, as a first component, a polyester-based resin, and as a second component, an olefin-based resin a melting point of which is lower than a melting point of the first component, in which the degree of orientation in the polyester-based resin is 6.0 or less, and the degree of crystallinity therein is 20% or more.　The conjugate fibers are preferably sheath-core conjugate fibers in which the first component is a core component and the second component is a sheath component.
