Abstract
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.
