Abstract

A modified cellulosic fiber having superabsorbent properties is described. The modified fiber of the invention has a fibrous structure substantially identical to the cellulosic fiber from which it is derived. The modified fiber is a water-swellable, water-insoluble fiber that substantially retains its fibrous structure in its expanded, water-swelled state. The modified fiber is a sulfated and crosslinked cellulosic fiber having a liquid absorption capacity of at least about 4 g/g. In one embodiment, the modified fiber is an individual, crosslinked, sulfated cellulosic fiber. In another aspects, the invention provides a rollgood that includes the modified fiber, absorbent composites and articles that include the modified fiber, and methods for making the modified cellulosic fiber.
