摘要： The object of the present invention is to provide a polypropylene spunbond nonwoven fabric excellent in its flexibility, bending resistance, texture and strength. A spunbond nonwoven fabric of the present invention is made of a propylene polymer composition containing a propylene polymer (A) having a melting point of not less than 120°C and a fatty acid amide having not less than 15 and not more than 21 carbon atoms. An oleic acid amide is preferred as the fatty acid amide having not less than 15 and not more than 21 carbon atoms. Preferably, the propylene polymer composition further contains a propylene polymer (B) having a melting point of less than 120°C.
