摘要

A spun-bonded nonwoven fabric that comprises a fiber formed of a composition, said composition containing a propylene homopolymer having a melting point of 140^°C or higher, a polyethylene and at least one kind of polymer selected from the group consisting of polymer (I) and polymer (II), wherein the fiber has a sea-island structure and, in a cross section along the long axis direction of the fiber, the average length of the island phase is 1-500 μm inclusive, and a method for manufacturing the spun-bonded nonwoven fabric. Polymer (I) is a random copolymer of propylene with an α-olefin having a specific number of carbon atoms and polymer (II) is a propylene homopolymer having a melting point of lower than 120^°C and satisfying a specific requirement in physical property.
