Abstract
A method for making a dispersible nonwoven sheet generally comprises dispersing natural fibers and regenerated fibers in a ratio of about 70 to about 90 percent by weight natural fibers and about 10 to about 30 percent by weight regenerated fibers in a liquid medium to form a liquid suspension. The liquid suspension is deposited over a foraminous forming wire to form a nonwoven tissue web. The nonwoven tissue web is sprayed with a first plurality of jets. Each jet of the first plurality of jets is spaced from an adjacent one of the first plurality of jets by a first distance. The nonwoven tissue web also is sprayed with a second plurality of jets. Each jet of the second plurality of jets is spaced from an adjacent one of the second plurality of jets by a second distance, and the second distance is less than the first distance. The nonwoven tissue web is dried to form the dispersible nonwoven sheet.
