摘要： An absorbent article is disclosed. The article includes a topsheet formed of a section of formed nonwoven web material having an ordered arrangement of zones, each zone comprising one or more attenuated regions adjacent to one or more built-up regions, wherein the attenuated regions have a first average basis weight and the built-up regions have a second average basis weight, wherein the first average basis weight is less than the second average basis weight, the difference in basis weights corresponding to disposition of the filaments according to the ordered arrangement. The attenuated region(s) may include a plurality of discrete low bulk portions arranged in a pattern disposed along a longitudinal axis of the article, which facilitate z-direction movement of fluid through the topsheet and inhibit spreading of a fluid stain along the topsheet in the x and y directions.

摘要： A shaped non-woven fabric for an absorbent has a first surface and a second surface and is usable with the second surface facing a constituent member of an absorbent article. The shaped non-woven fabric is includes a thermoplastic resin fiber. The non-woven fabric includes a plurality of first recesses which have openings in the first surface and are recessed toward the second surface, and a plurality of through-holes which penetrate from the first surface to the second surface. Each of the plurality of first recesses has a peripheral wall section which extends in the thickness direction from the end edges of the openings toward the second surface, and a bottom section connected to the end edge of the peripheral wall section. At least a portion of the plurality of first recesses includes a hole section which penetrates from the first surface to the second surface.
