Title:
HEAT-BONDABLE COMPOSITE FIBER, MANUFACTURING METHOD FOR SAME, AND NON-WOVEN FABRIC USING HEAT-BONDABLE COMPOSITE FIBER
Document Type and Number:
WIPO Patent Application WO/2022/050189
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a heat-bondable composite fiber from which a non-woven fabric that has an excellent texture and excellent shaping properties can be obtained. Provided is a heat-bondable composite fiber which comprises a first component that contains a polyester-based resin and a second component that contains a polyolefin-based resin having a melting point lower than that of the polyester-based resin by 15°C or more and which has a concentric core-shell structure in which, in a cross section of a fiber perpendicular to the lengthwise direction of the fiber, the second component occupies the outer circumference of the fiber, wherein elongation at break is 350% or more, and the ratio of elongation at break to fineness is 80%/dtex or more.
