资源简介：
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.
