Abstract:
It is an object of the present invention to obtain crimped conjugated fibers having excellent crimp properties. The present invention provides a crimped conjugated fiber having a crimpable cross-sectional configuration, wherein a cross section of the fiber includes at least two portions: a portion (a) and a portion (b); the portion (a) includes an olefin polymer (A) and the portion (b) includes an olefin polymer (B); the olefin polymer (A) differs from the olefin polymer (B) in at least any one of Mz/Mw, melting point and MFR; and a specific fatty acid amide is added to the olefin polymer (A) and/or the olefin polymer (B). The present invention also provides a non-woven fabric including said crimped conjugated fiber.
