A method for producing a high-bulk, foam-formed substrate includes producing an aqueous-based foam including at least 1% by weight crimped synthetic fibers and at least 1% by weight binder fibers; forming a wet sheet from the aqueous-based foam; and drying the wet sheet to obtain the foam-formed substrate. A substrate includes an aqueous-based polymer foam including at least 1% by weight crimped synthetic fiber and at least 1% by weight binder fiber, wherein the substrate is free of superabsorbent material. A method for producing a high-bulk, foam-formed substrate includes producing an aqueous-based foam including at least 2% by weight crimped binder fibers; forming a wet sheet from the aqueous-based foam; and drying the wet sheet to obtain the foam-formed substrate, wherein the foam-formed substrate is free of superabsorbent material, and wherein the substrate has a dry density between 0.02 g/cc and 0.1 g/cc.

Foam-formed fibrous sheets with crimped staple fibers

A process for foam forming webs is described herein. A foamed suspension of fibers is fed into a mixing chamber and then directed through a narrow constriction where the velocity of the foamed suspension of fibers is increased. From the narrow constriction, the foamed suspension of fibers enters a forming chamber which causes the foamed suspension of fibers to rapidly decrease in velocity. In one embodiment, for example, the foamed suspension of fibers undergoes a hydraulic jump resulting in significant fiber reorientation. Through the process, fiber orientation can be controlled. For example, webs can be produced that have comparable fiber orientation in the machine direction in comparison to the cross-machine direction.

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 making a high topography nonwoven substrate includes generating a foam including water and synthetic binder fibers; depositing the foam on a planar surface; disposing a template form on the foam opposite the planar surface to create a foam/form assembly; heating the foam/form assembly to dry the foam and bind the synthetic binder fibers; and removing the template from the substrate after heating the foam/form assembly, wherein the substrate includes a planar base layer having an X-Y surface and a backside surface opposite the X-Y surface; and a plurality of projection elements integral with and protruding in a Z-direction from the X-Y surface, wherein the projection elements are distributed in both the X- and Y-directions, and wherein the density of a projection element is the same as the density of the base layer.

Process for making three-dimensional foam-laid nonwovens

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

A multi-layered web is disclosed that is resilient and/or elastic in the Z-direction. Thus, when the web is compressed, the web assumes a compacted state and then expands to an expanded state when the compressive forces are removed. In one embodiment, the multi-layered web includes a middle layer made from a resilient blend of fibers positioned inbetween two outer layers. The middle layer, for instance, can contain elastomeric fibers, three-dimensional fibers, and/or debonded fibers.

Resilient, multi-layered wiping product

A system comprising a pulper configured to (i) accept surfactant, a liquid and fiber stock and (ii) generate a foam that suspends the fiber stock, wherein the foam has a half-life; a headbox configured to receive the foam-suspended fiber stock from the pulper and displace the foam-suspended fiber stock onto a forming wire, wherein a time it takes the foam-suspended fiber stock to move from the pulper to the headbox is less than the half-life; and a foam return device that removes at least some of the foam from the forming wire and returns the at least some of the foam to the pulper.

Foam-based manufacturing system and process

A polymeric material for use in thermal insulation is provided. The polymeric material is formed from a thermoplastic composition containing a continuous phase that includes a matrix polymer and within which a microinclusion additive and nanoinclusion additive are dispersed in the form of discrete domains. A porous network is defined in the material that includes a plurality of nanopores having an average cross-sectional dimension of about 800 nanometers or less. The polymeric material exhibits a thermal conductivity of about 0.20 watts per meter-kelvin or less.

Polymeric material for use in thermal insulation

As described herein, an extensible sheet material includes a first and a second zone that is separate from the first zone. The first zone exposes a first color or pattern when the extensible sheet material is stretched beyond a first percentage. The second zone exposes a second color or pattern when the extensible sheet material is stretched beyond a second percentage greater than the first percentage. Absorbent articles that include the extensible sheet material are capable of indicating to a wearer when the extensible sheet material has been stretched too little, too much, or just the right amount.

Extensible sheet material with visual stretch indicator

A method of making an absorbent structure having a three-dimensional topography includes placing at least a portion of the absorbent structure between opposed mold surfaces. At least one of the mold surfaces has a three-dimensional topography. The three-dimensional topography of the mold surface is imparted onto the absorbent structure so that the absorbent structure has a three-dimensional topography corresponding to the three-dimensional topography of the mold surface.

An antimicrobial wipe that contains a polymer coating having a synergistic combination of ingredients for providing controlled release of an antimicrobial agent and also good antimicrobial efficacy is provided. One such ingredient is a high molecular weight polyamideamine release agent. Due to the polycationic nature of the release agent, it is able to adhere to the wipe, which is generally formed from fibers having a negative surface charge (e.g., cellulosic fibers). In this manner, the release agent can occupy binding sites on the wipe to inhibit the antimicrobial agent from adhering thereto, thus allowing it to be expressed in the germicidal solution to kill microbes on the desired surface. The adherence of the release agent to the wipe is even further enhanced by crosslinking the polyamideamine to increase its molecular weight, thereby enabling it to form a structural network that physically adheres to the wipe and that blocks the antimicrobial agent from binding thereto. Furthermore, the polyamideamine is amidated so that it contains secondary and/or tertiary amides. A cell permeabilizer is also employed in the polymer coating to enhance the efficacy of the antimicrobial agent during use. More particularly, polycationic materials are particularly useful in permeabilizing the outer cell membrane without adversely impacting the ability of the polyamideamine to release the antimicrobial agent within the wipe.
