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%.
