Abstract
Absorbent articles comprising topsheet laminates bonded with substantially tackifier-free adhesives, wherein the topsheet laminates comprise morphological treatments.
Claims27
An absorbent article comprising:
- a liquid permeable topsheet;
- a liquid impermeable backsheet;
- an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet;
- and
- a substrate positioned between the topsheet and the absorbent core;
- wherein the topsheet and the substrate are joined by an adhesive to form a laminate;
- wherein the laminate comprises a morphological treatment;
- and
- wherein the adhesive is a substantially tackifier-free adhesive.
6 more elements
A liquid permeable substrate for an absorbent article, the substrate comprising:
- a first layer comprising a hydrophobic material;
- and
- a second layer comprising a hydrophilic material, wherein the first layer is joined to the second layer by an adhesive;
- wherein the substrate comprises a plurality of recesses, a plurality of projections, and a plurality of land areas, wherein the land areas surround at least a majority of the plurality of projections and a plurality of the recesses, wherein the plurality of recesses, the plurality of projections, and the plurality of land areas, together form a first three-dimensional surface on a first side of the substrate and a second three-dimensional surface on a second side of the substrate, wherein a majority of the projections have a z-directional height in the range of about 500 μm to about 4000 μm, according to the Projection Height Test, wherein a majority of the recesses define an aperture at a location most distal from a top peak of an adjacent projection, and wherein the majority 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;
- and
- wherein the substrate has an overall z-directional height in the range of about 1000 μm to about 6000 μm, according to the Overall Substrate Height Test;
- and
- wherein the adhesive is a substantially tackifier-free adhesive.
