Cross-linked pulp and method of making same

A process for preparing crosslinked cellulosic fibers in sheet form, which process comprises: (a) applying a crosslinking agent carboxylic acid polymer to a sheet of mercerized cellulosic fibers wherein said fibers have not been mechanically refined prior to conversion sheet, and wherein the alpha-cellulose purity of the mercerized fibers is at least 95%; and (b) curing the crosslinking agent on said sheet of mercerized cellulosic fibers to form crosslinked cellulosic fibers having substantial intrafiber cross-links without substantial interfiber cross-links.
