Process for making three-dimensional foam-laid nonwovens

A method for making a high topography nonwoven substrate includes generating a foam including water and synthetic binder fibers; depositing the foam on a planar surface; disposing a template form on the foam opposite the planar surface to create a foam/form assembly; heating the foam/form assembly to dry the foam and bind the synthetic binder fibers; and removing the template from the substrate after heating the foam/form assembly, wherein the substrate includes a planar base layer having an X-Y surface and a backside surface opposite the X-Y surface; and a plurality of projection elements integral with and protruding in a Z-direction from the X-Y surface, wherein the projection elements are distributed in both the X- and Y-directions, and wherein the density of a projection element is the same as the density of the base layer.

An absorbent article which can have an improved feeling of comfort next to the skin of the wearer and a reduction in the feelings of wetness and rewet. An absorbent article can have a longitudinal direction, a transverse direction, and a depth direction. The absorbent article can have a topsheet layer, a backsheet layer, and an absorbent core positioned between the topsheet layer and the backsheet layer. The topsheet layer can have a hydrophilic central layer, a semi-hydrophilic first side layer, and a semi-hydrophilic second side layer. Each of the semi-hydrophilic side layers can be bonded to the central layer utilizing an embossing technique in the regions of overlap of each of the semi-hydrophilic side layers with the central layer. The area of the body-facing surface of each of the regions of overlap can contain from about 10% to about 35% of at least one embossment.
