Abstract:
A tissue paper product is provided having at least one ultra-low density ply having a highly porous, open-celled structure and that comprises cellulosic fibers, a water insoluble binder and a foaming surfactant. The cellulosic fiber comprises greater than 50% by weight of the ply and are bonded to one another by hydrogen bonding. Further, the ply has a density less than about 0.04 g/cc and yet still provides low lint and high strength properties with the use of minimal binder. The ultra-low density ply may comprise or be included in sheets forming a stack of dispensable wipers or may be employed as or part of an absorbent core or liquid distribution layer of a personal care absorbent personal care product such as a diaper or feminine pad.
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:
A method is presented for forming a collapsed foam film-like structure, the method including positioning a composition applicator adjacent to a hot non-permeable dryer surface, producing a first frothed dispersion or frothed solution from a first dispersion or solution, applying the first frothed dispersion or frothed solution to the dryer surface, allowing the first frothed dispersion or frothed solution to convert to a collapsed foam film-like structure, and scraping the collapsed foam film-like structure from the dryer surface. The method can further include producing a second dispersion or solution, blending the first dispersion or solution and the second dispersion or solution, frothing the blended dispersion or solution, applying the blended frothed dispersion or frothed solution to the dryer surface, and allowing the frothed dispersion or frothed solution to convert to a collapsed foam film-like structure.
Abstract:
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.
Abstract:
It has now been discovered that the sheet bulk of a tissue web may be increased, with little or no degradation in tensile strength, by forming the web with at least a portion of cellulosic fiber that has been reacted with a water soluble cellulose reactive agent such as a cyanuric halide or a vinyl sulfone and then reacting the fiber with monochloroacetic acid, or salts thereof, in the presence of a caustic.
