Abstract
A multi-component topsheet for an absorbent article includes a first discrete substrate, a second discrete substrate, and a third discrete substrate, wherein the second discrete substrate is disposed at least partially intermediate the first discrete substrate and the third discrete substrate, wherein the second discrete substrate is joined to the first discrete substrate and the third discrete substrate, wherein the topsheet has a single layer of substrate in about 80% or more of the total area of the topsheet and a dual layer of substrate in about 20% or less of the total area of the topsheet.
Claims20
An absorbent article comprising:
- a central longitudinal axis;
- a liquid permeable topsheet;
- a backsheet;
- and
- an absorbent core positioned at least partially intermediate the topsheet and the backsheet;
- the topsheet comprising:
- a first layer comprising a hydrophobic nonwoven material, wherein the hydrophobic nonwoven material overlaps the central longitudinal axis;
- and
- a second layer comprising a hydrophilic nonwoven material wherein the hydrophilic nonwoven material overlaps the central longitudinal axis, and wherein the first layer is joined to the second layer;
- wherein the topsheet comprises a plurality of recesses, a plurality of dome-shaped projections forming a portion of a wearer-facing surface of the topsheet, and a plurality of land areas, wherein plurality of the land areas surround the plurality of the dome-shaped projections and the plurality of the recesses, wherein the plurality of the recesses, the plurality of the dome-shaped projections, and the plurality of the land areas, together form a first three-dimensional surface on a first side of the topsheet and a second three-dimensional surface on a second side of the topsheet, wherein the plurality of the dome-shaped projections have a z-directional height in the range of about 500 μm to about 4000 μm, according to the Projection Height Test, wherein at least some of the plurality of the recesses define an aperture at a location most distal from a top peak of an adjacent dome-shaped projection and defined at a lowermost plane of the topsheet, and wherein the plurality of the recesses have a z-directional height in the range of about 500 μm to about 2000 μm, according to the Recess Height Test;
- wherein the topsheet has an overall z-directional height in the range of about 1000 μm to about 6000 μm, according to the Overall Substrate Height Test;
- wherein a plurality of the apertures have an effective aperture area in the range of about 0.5 mm2 to about 3 mm2, according to the Aperture Test;
- and
- wherein the topsheet has a % effective open area in the range of about 5% to about 25%, according to the Aperture Test.
