Spunbond nonwoven fabric, sanitary material, and manufacturing method of spunbond nonwoven fabric

摘要

A propylene homopolymer having a melting point of 140° C. or higher, and a fiber comprising a composition containing at least one polymer selected from the group consisting of polyethylene and a polymer represented by (I) and a polymer represented by (II), and the fiber A spunbond nonwoven fabric having a structure and having an average length of an island shape in a cross section along a long axis direction of a fiber is 1 μm or more and 500 μm or less, and a method for producing the same. The polymer represented by (I) is a random copolymer of propylene and an α-olefin having a specific carbon number, and the polymer represented by (II) is a propylene homopolymer having a melting point of less than 120°C that satisfies specific physical properties.
