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%.

Abstract: An absorbent article having a fluid-handling system includes a fluid permeable bodyside liner; a fluid impermeable outer cover; an absorbent core disposed between the liner and the outer cover, wherein the absorbent core includes superabsorbent material and optionally fluff pulp; a tissue core wrap encircling the absorbent core; and a distribution sub-layer disposed between the absorbent core and the outer cover and within the core wrap, wherein the distribution sub-layer includes a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material. The distribution sub-layer includes opposing distribution sub-layer surfaces each having a textured surface, wherein each surface includes an average material plane, a plurality of ridges extending in a z-direction from the average material plane, and a plurality of grooves alternating with the plurality of ridges, wherein the grooves depth extend in the opposite z-direction from the average material plane.

Abstract: An absorbent article having a fluid-handling system includes a fluid permeable bodyside liner; a fluid impermeable outer cover; an absorbent core disposed between the liner and the outer cover, wherein the absorbent core includes superabsorbent material and optionally fluff pulp; and a core wrap at least partially encircling the absorbent core, wherein the core wrap includes a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material. Fibers of the nonwoven material are entirely cellulose fibers, and the core wrap includes opposing core wrap surfaces each having a textured surface. Each surface includes an average material plane, a plurality of ridges extending in a z-direction from the average material plane, and a plurality of grooves alternating with the plurality of ridges, wherein the grooves depth extend in the opposite z-direction from the average material plane.
