Abstract: A high topography nonwoven substrate includes synthetic binder fibers; 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 each projection element has a height, a diameter or width, a cross-section, a sidewall, a proximal end where the projection element meets the base layer, and a distal end opposite the proximal end, 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.
