A disposable absorbent article includes a bodyside liner, an outer cover, an absorbent body disposed between the bodyside liner and the outer cover, and a surge layer disposed between the bodyside liner and the absorbent body, the surge layer having an X-Y plane, a Z-direction, and a longitudinal direction, and a barrier extending substantially through the surge material in the Z-direction, wherein the barrier is configured to block at least one linear longitudinal fluid flow path. The surge layer can alternatively have a plurality of barriers extending substantially through the surge material in the Z-direction, wherein the plurality of barriers is configured to block a plurality of linear longitudinal fluid flow paths or all linear longitudinal fluid flow paths while allowing non-linear fluid flow paths in the longitudinal direction.

Disposable absorbent article with surge layer including at least one barrier

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%.

Fibrous sheet with improved properties

An absorbent structure expands to a greater extent along one surface than along an opposite surface when in the presence of a liquid. The absorbent structure may include a single layer, or two or more layers intimately bonded to one another. When in the presence of a liquid, the more expandable surface causes an increase in concavity in the X-Y plane of the structure, with the concavity being in the direction of the less expandable surface. One or both surfaces can be treated to adjust the respective level of expandability. By inducing a formed shape upon hydration swelling, a trough shape can be generated to facilitate absorbent properties, containment, and fit. The invention includes absorbent articles having such an absorbent structure incorporated therein.

Differentially expanding absorbent structure

Personal care products comprising supersaturated solutions and core compositions comprising activation means are disclosed. In one embodiment, a core composition comprising the activation means is surrounded by an encapsulation layer. The core composition comprising the activation means may be introduced into wet wipes such that, upon rupture and contact between the supersaturated solution and the activation means, the wet wipe solution is warmed resulting in a warm sensation on a user's skin. Any number of other active ingredients, such as biocides, can also be incorporated into the personal care product.
