Abstract: The present disclosure features a composite fabric, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.
