Absorbent fibers include cellulose fibers modified through chemical modification, wherein the chemical modification is selected from carboxymethylated, sulfonated, sulfated or phosphonated. Absorbent fibers can be substantially water insoluble and water swellable. Absorbent fibers exhibit a centrifugation retention capacity and an absorption rate of 0.0001 to 0.01 sec −1 after 4 hours of 1.4 to 8 grams / gram. Absorbent articles having a surfacesheet, a backsheet, and an absorbent core may also include absorbent fibers. |
