摘要:
A liquid permeable substrate for an absorbent article is disclosed. The substrate includes a first layer including a hydrophobic material and a second layer including a hydrophilic material. The first layer is joined to the second layer. The substrate includes a plurality of recesses, a plurality of projections, and a plurality of land areas. The land areas surround at least a majority of the plurality of projections and a plurality of the recesses. The plurality of recesses, the plurality of projections, and the plurality of land areas together form a first three-dimensional surface on a first side of the substrate and a second three-dimensional surface on a second side of the substrate. The substrate has an overall z-directional height in the range of about 1000 μm to about 6000 μm according to the Overall Substrate Height Test.
