Patent ID: 10174441

Abstract:
A laminated nonwoven fabric (NF) includes a first NF containing first fibers and a second NF containing second fibers and laminated on the first NF, and has a cut-off edge at an end thereof. An average diameter of the first fibers is larger than that of the second fibers not more than 3 μm. 50% by mass to 70% by mass, inclusive, of the second fibers satisfy x≥y, and 5% by mass to 30% by mass, inclusive, thereof satisfy x<y/2. “x” is a vector component in a direction (X axis direction) of the cut-off edge, and “y” is a vector component in Y axis direction perpendicular to X axis and parallel to a principal surface of the laminated NF. When the second NF is viewed from Z axis direction perpendicular to X and Y axes, at least some of the second fibers satisfying x<y/2 overlap the second fibers satisfying x≥y.
