Spunbonded Nonwoven Fabric
Abstract: The present invention provides a highly flexible spunbonded nonwoven fabric that has a uniform texture, a smooth surface, and excellent feeing and tactile property, and that comprises highly productive polyolefin fibers having preferable spinnability while having a small average single fiber diameter. The present invention pertains to a spunbonded nonwoven fabric made of fibers comprising a polyolefin resin, wherein the average single fiber diameter of the fibers is 6.5-11.9 µm, the fiber dispersity obtained by using reflected light brightness is 10 or lower, and the surface roughness SMD of at least one surface of the fabric as measured by a KES method is 1.0-2.6 µm.
