Zusammenfassung:A compressed substrate having an altered upper surface is generally disclosed. The compressed substrate is configured to expand in the z-direction upon contact with a liquid to form an expanded substrate without substantially expanding in either the x-direction or the y-direction. The altered upper surface of the expanded substrate has an expanded surface area that is at least about 110% of the initial surface area of the compressed substrate. The compressed substrate is constructed from a compression molded web and includes an active agent. The compressed substrate can be included within the construction of an absorbent article to transfer the active agent to a wearer. The upper surface of a compressed substrate can be altered after formation of the compressed substrate. Alternatively, the upper surface of the compressed substrate can be altered during the compression process.
