CRIMPED FIBER AND NONWOVEN FABRIC

WIPO Patent Application WO/2015/141750

A1

　A crimped fiber composed of a first component and a second component below, wherein the first component is a propylene-based resin composition including a propylene-based polymer (1-A) in which the melting point (Tm-D) obtained under a specific condition exceeds 120℃ and a propylene-based polymer (1-B) satisfying conditions that (a) a weight-average molecular weight (Mw) is 10,000-200,000, (b) molecular weight distribution (Mw/Mn) is less than 4.0, and (c) the melting point (Tm-D) obtained under a specific condition is 0-120℃; and the second component is a propylene-based polymer (2) in which the melt flow rate (MFR) measured under the measurement condition is 1 to 2,000 g/10 min inclusive and the melting point (Tm-D) observed under the measurement condition using a differential scanning calorimeter (DSC) exceeds 120℃; or a propylene-based resin composition including the propylene-based polymer (2).
