Abstract
A water-dispersible nonwoven substrate includes a structured web of fibers. The structured web has a first surface and a second surface. The first surface has substantially filled protrusions extending outwardly from the first surface and connecting regions disposed between the protrusions. The average fiber densities of the protrusions and connecting regions are substantially the same, and the fibers are individualized plant-based fibers, reconstituted cellulosic fibers, or a combination thereof.
