A method for manufacturing a composite material includes forming a composite precursor material comprising a nonwoven layer comprising a plurality of fibers and a polymer film layer laminated to the nonwoven layer; forming a plurality of apertured extended cells in the polymer film layer, each of the apertured extended cells having a continuous sidewall extending away from the nonwoven layer that terminates in an aperture at a distal end; and, while forming the plurality of apertured extended cells, pushing, with a fluid, at least one of the fibers into at least one of the apertured extended cells so that a portion of the at least one of the fibers extends into the at least one of the apertured extended cells and through the aperture at the distal end.

The present invention is directed to a nonwoven fabric made from a composite of nonwoven and pulp where the nonwoven has a high loft derived from a heat set three-dimensional relief structure and/or hydroengorged fiber structure. A nonwoven web is hydraulically treated to create a hydroengorged material having an increased loft. Alternatively a nonwoven web is treated to have a heat set three-dimensional relief structure. The treated web is then hydroentangled with pulp to form a cotendered nonwoven/pulp composite fabric.

A dispersible moist wipe includes regenerated cellulose fibers in an amount equal to or less than 20 percent by weight and natural cellulose fibers in an amount equal to or greater than 80 percent by weight. At least 50 percent of the natural cellulose fibers are fibrillated. The regenerated cellulose fibers and the natural cellulose fibers are hydroentangled such that the web has a wet CD tensile strength of at least 200 grams per inch. A method of making a dispersible nonwoven sheet includes dispersing natural cellulose fibers and regenerated cellulose fibers in a liquid medium to form a liquid suspension and depositing the liquid suspension over a forming surface to form a nonwoven web. The natural cellulose fibers and regenerated cellulose fibers of the web are hydroentangled using a plurality of hydroentangling jets.
