Document Type and Number:

WIPO Patent Application WO/2010/024147

Kind Code:

A1

Abstract:

A nonwoven polypropylene fabric excellent in both initial hydrophilicity and long-lasting hydrophilicity. Namely, the fabric comes to have hydrophilicity in a short time after the production thereof (initial hydrophilicity) and recovers the hydrophilicity in a short time even when the nonwoven fabric is heat-treated (long-lasting hydrophilicity). Also provided are fibers of a propylene copolymer composition comprising 100 parts by weight of a propylene/α-olefin random copolymer having a melting point (Tm) in the range of 125-155ºC and 0.5-5 parts by weight of a nonionic surfactant comprising an alkylene oxide adduct of an aliphatic alcohol. The nonwoven fabric is constituted of the fibers. Furthermore provided is a use of the nonwoven fabric.
