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: A method for producing a foam-formed multilayered substrate that includes producing an aqueous-based foam including at least 3% by weight non-straight synthetic binder fibers, wherein the non-straight synthetic binder fibers have an average length greater than 2 mm; forming together a wet sheet layer from the aqueous-based foam and a cellulosic fiber layer, wherein the cellulosic fiber layer includes at least 60 percent by weight cellulosic fibers; and drying the combined layers to obtain the foam-formed multilayer substrate. A multilayered substrate includes a first layer including at least 60 percent by weight non-straight synthetic binder fibers having an average length greater than 2 mm; and a second layer including at least 60 percent by weight cellulosic fiber, wherein the first layer is in a facing relationship with the second layer, and wherein the multilayered substrate has a wet/dry tensile ratio of at least 60%.
