摘要： Methods of forming crosslinked cellulose include mixing a crosslinking agent with cellulose mat fiber fragments composed of hydrogen-bonded cellulose fibers and having a solids content of about 45-95% to form a substantially homogenous mixture of non-crosslinked, individualized cellulose fibers, drying the resulting mixture to 85-100% solids, then curing the dried mixture under conditions effective to crosslink the cellulose fibers. Some of such methods may include fragmenting a cellulose fiber mat to form the mat fragments. Systems include a mixing unit (such as a high-consistency mixer) configured to form, from the mat fragments and a crosslinking agent, a substantially homogenous mixture of non- crosslinked, individualized cellulose fibers and crosslinking agent, at ambient conditions, a drying unit to dry the substantially homogenous mixture to a consistency of 85-100%, and a curing unit and to cure the crosslinking agent to form dried and cured crosslinked cellulose fibers.

摘要： 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.
