Abstract: A method for producing a foam-formed multilayered substrate that includes producing an aqueous-based foam including at least 3% by weight non-straight synthetic binder fibers, wherein the non-straight synthetic binder fibers have an average length greater than 2 mm; forming together a wet sheet layer from the aqueous-based foam and a cellulosic fiber layer, wherein the cellulosic fiber layer includes at least 60 percent by weight cellulosic fibers; and drying the combined layers to obtain the foam-formed multilayer substrate. A multilayered substrate includes a first layer including at least 60 percent by weight non-straight synthetic binder fibers having an average length greater than 2 mm; and a second layer including at least 60 percent by weight cellulosic fiber, wherein the first layer is in a facing relationship with the second layer, and wherein the multilayered substrate has a wet/dry tensile ratio of at least 60%.

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.
