Abstract: Absorbent substrates including a high percentage of superabsorbent material and method of manufacturing such absorbent substrates are disclosed. An absorbent substrate can include an intake layer including a first plurality of fibers and an absorbent layer. The absorbent layer can include superabsorbent material providing greater than 80% of the absorbent layer by total weight of the absorbent layer. The intake layer and the absorbent layer can provide an integrated material including an interface between the intake and absorbent layers. The interface can include at least some of the first plurality of fibers of the intake layer mixed with at least some of the absorbent layer.

Abstract: Methods and apparatuses for forming fibrous web structures are disclosed. In one embodiment, a method of forming a fibrous web comprises positioning a masking media over a foraminous forming member having a forming surface, the masking media producing covered portions and uncovered portions of the forming surface, applying vacuum pressure so as to draw air through the forming surface, depositing fibrous material onto the forming surface to form a fibrous web. The masking media may be flexible such that the at least one masking media is sucked tight to the forming surface and forms direct contact with the forming surface where vacuum pressure is applied, thereby preventing the fibrous material from flowing between the at least one masking media and the forming surface.
