Title:
SPUNBONDED NONWOVEN FABRICS, SANITARY MATERIALS, AND METHOD FOR DRAWING OF SPUNBONDED NONWOVEN FABRIC
Document Type and Number:
Japanese Patent JP2021161564
Kind Code:
A
Abstract:
To provide a spunbonded nonwoven fabric excellent in elongation property, a method for drawing the same, and a sanitary material using a spunbonded nonwoven fabric.SOLUTION: There is provided a spunbonded nonwoven fabric which comprises a composition containing a propylene homopolymer having a melting point of 140°C or higher, polyethylene, and at least one polymer selected from the group consisting of the polymer shown in (I) and the polymer shown in (II). A ratio (MD/CD) of the strength in the flow direction (MD) to the strength in the lateral direction (CD) is 2.0 or more and 4.0 or less, and 5% strength in the flow direction (MD) is 5 to 9. The polymer shown in (I) is a random copolymer of propylene and an α-olefin having a specific carbon number, and the polymer shown in (II) is a propylene homopolymer having a melting point of less than 120°C and satisfies specific physical properties.SELECTED DRAWING: None
