摘要： 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%.

摘要： A nonwoven substrate includes individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter. The pattern elements can be recessed into and/or extend out of the fiber surface, and the nonwoven substrate can include polypropylene or polyethylene. A disposable absorbent article includes a nonwoven substrate having individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter.

摘要： The present disclosure relates to tissue products comprising crosslinked fibers. The tissue products generally have good formation, such as a Formation Index greater than about 20, strength, such as geometric mean tensile strengths greater than about 700 g/3″ and high bulk, such as sheet bulks greater than about 10 cc/g. Unlike many prior art crosslinked fibers, the crosslinked softwood pulps of the present invention, which are preferably prepared using a glyoxal based crosslinking reagent, are readily dispersible in water and have relatively low degrees of kink and curl. As such, the fibers are well suited for forming wet-laid tissue products and more particularly wet-laid tissue products having improved physical properties, such as improved bulk.
