Abstract
A method of making an absorbent structure having a three-dimensional topography includes placing at least a portion of the absorbent structure between opposed mold surfaces. At least one of the mold surfaces has a three-dimensional topography. The three-dimensional topography of the mold surface is imparted onto the absorbent structure so that the absorbent structure has a three-dimensional topography corresponding to the three-dimensional topography of the mold surface.
