This invention provides a polypropylene-based spunbonded nonwoven fabric with excellent properties of softness, bending resistance, touching feel and strength. The spunbonded nonwoven fabric includes a propylene-based polymer composition containing (A) a propylene-based polymer with a melting point of 120℃ or more and a fatty acid amide having a carbon number of 15 to 21. The fatty acid amide having a carbon number of 15 to 21 is an oleic acid amide. The propylene-based polymer composition further includes (B) a propylene-based polymer with a melting point of under 120℃.本發明提供柔軟性、抗彎曲性、觸感、強度優異的聚丙烯系紡絲黏合不織布。此紡絲黏合不織布包括丙烯系聚合物組成物,上述丙烯系聚合物組成物含有(A)熔點為120℃以上的丙烯系聚合物以及碳數為15以上21以下的脂肪酸醯胺。碳數為15以上21以下的脂肪酸醯胺為油酸醯胺。丙烯系聚合物組成物更包括(B)熔點未達120℃的丙烯系聚合物。
