PROBLEM TO BE SOLVED: To provide a polypropylene nonwoven fabric composed of propylene.α- olefin random copolymeric fibers, capable of hot-melt binding at relatively low temperatures and high bindability to the polypropylene fibers. SOLUTION: This nonwoven fabric is obtained by blending 1st fibers of a propylene polymer with 2nd fibers of the propylene.α-olefin random copolymer polymerized by a metallocene catalyst and having the following properties: MFR is 5-100 g/10 min, Q-value is 2.0-4.0, Tm is 110-135 deg.C andα-olefin content is 1-18 mol%; wherein the 2nd fibers are used as a binder for the 1st fibers.
