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 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

The present invention provides tissue webs and products that are manufactured by non-compressive dewatering and/or drying methods, such as through-air drying, where the webs and products comprise cross-linked fiber. The non-compressively dewatered tissue webs and products have improved sheet bulk and z-direction properties. For example, in one embodiment, the invention provides through-air dried tissue products having good sheet bulk and resiliency, such as a sheet bulk greater than about 15 cc/g and Compression Energy (E) greater than about 1.30 N/m. Surprisingly the foregoing products have sufficient strength to withstand use, such as a GMT greater than about 600 g/3&#x2033;, but are not overly stiff, generally having a Stiffness Index less than about 12.

Resilient high bulk tissue products

The disclosure provides tissue webs and products comprising cross-linked cellulosic fibers. In certain embodiments cross-linked cellulosic fibers are selectively disposed in one or more layers of a multi-layered tissue, wherein the tissue layer comprising cross-linked fibers is adjacent to a layer which is substantially free from cross-linked fiber. The cross-linked fibers may include hardwood kraft fibers reacted with a cross-linking agent selected from the group consisting of DMDHU, DMDHEU, DMU, DHEU, DMEU, and DMeDHEU. Tissue products and webs produced in this manner generally have improved sheet bulk, without losses in strength, compared to similar tissue products produced without cross-linked cellulosic fibers. As such the tissue products of the present invention generally have a basis weight from about 10 to about 50 gsm, a sheet bulk greater from about 8.0 to about 12.0 cc/g and geometric mean tensile from about 730 to about 1,500 g/3&#x2033;.

Soft, strong and bulky tissue

The present invention provides tissue webs and products that are manufactured by non-compressive dewatering and/or drying methods, such as through-air drying, where the webs and products comprise cross-linked fiber. The non-compressively dewatered tissue webs and products have improved sheet bulk and z-direction properties. For example, in one embodiment, the invention provides through-air dried tissue products having good sheet bulk and resiliency, such as a sheet bulk greater than about 12 cc/g and Compression Energy (E) greater than about 1.30 N/m. Surprisingly the foregoing products have sufficient strength to withstand use, such as a GMT greater than about 1,200 g/3&#x2033;, but are not overly stiff, generally having a Stiffness Index less than about 10.0.

Resilient high bulk towels

The present application relates to a cross-linked fiber and more specifically to fibers that have been subjected to cold caustic extraction (at less than 60&#xb0; C.) to reduce the hemicellulose content of the fibers by at least 50% and then cross-linked with a cross-linking agent that is curable at a modest temperature, such as less than 160&#xb0; C. The treated cross-linked fibers preferably have a hemicellulose content that is less than 5% by weight of the fiber. Preferable cross-linking agents are polyamide-epichlorohydrin (PAE) resins, polyamide-polyamine-epichlorohydrin (PPE) resins, and polydiallylamine-epichlorohydrin resins. The cross-linked fibers are readily dispersible in water even without fiberization and generally form webs and products having relatively few knits or knots. As such, the cross-linked fibers of the present invention are well suited for use in the manufacture of tissue webs and products, particularly wet-laid tissue webs and products.

High bulk tissue comprising cross-linked fibers

The present invention relates to prebiotic compositions and formulations comprising an &#x3b1;-hydroxy acid and salts thereof, such as lactic, glycolic, citric, tartaric or malic acid and a prebiotic agent, such as inulin, fructo-oligosaccharide (FOS), lactulose, galacto-oligosaccharide (GOS), raffinose, stachyose, isomalto-oligosaccharide, and xylo-oligosaccharide. Prebiotic compositions of the present invention provide a surprisingly synergist prebiotic effect and may be administered in several forms to a user, such as by application to a premoistened wiping substrate or dry bath tissue.

Synergistic prebiotic composition

The invention relates to creped prebiotic tissue products. The tissue products comprise prebiotics in sufficiently high amounts to have a prebiotic effect in use, without negatively affecting tissue product properties, such as tensile strength, stiffness or softness. Thus, in certain embodiments the present invention provides soft, durable creped prebiotic tissue products that are able to improve the growth of healthy bacteria such asspp. orspp. without promoting growth of enteropathogenic bacteria. The tissue products provide these benefits yet have a GMT greater than about 500, a Stiffness Index less than about 20 and a TS7 value less than about 10.

Creped prebiotic tissue

The disclosure provides a multilayered tissue web comprising treated cellulosic fibers selectively disposed in one or more layers, wherein the tissue layer comprising treated fibers is adjacent to a layer comprising untreated fiber and which is substantially free from untreated fiber. Generally the treated fibers have a rate of substitution of about 0.02 to 0.07. In this manner, the disclosure provides a multi-layered tissue web having treated fiber selectively incorporated therein, where the tissue web has basis weight greater than about 10 grams per square meter (gsm), such as from about 10 to about 50 gsm, a sheet bulk greater than about 8 cc/g, such as from about 8 to about 15 cc/g and Stiffness Index less than about 15, such as from about 8 to about 12.
