The fiber， method， and system which were modify

Methods of forming crosslinked cellulose include mixing a crosslinking agent with an aqueous mixture of cellulose fibers containing little to no excess water (e.g.， solids content of 25-55%)， drying the resulting mixture to 85-100% solids， then curing the dried mixture to crosslink the cellulose fibers. Systems include a mixing unit to form， from an aqueous mixture of unbonded cellulose fibers having a solids content of about 25-55% and a crosslinking agent， a substantially homogenous mixture of non- crosslinked， unbonded cellulose fibers and crosslinking agent; 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. Intrafiber crosslinked cellulose pulp fibers produced by such methods and/or systems have a chemical on pulp level of about 2-14% and an AFAQ capacity of at least 12.0 g/g.
