Abstract: A modified kraft pulp fiber with unique properties is provided. The modified fiber can be a modified bleached kraft fiber that is almost indistinguishable from its conventional counterpart, except that it has a low degree of polymerization (DP). Methods for making the modified fiber and products made from it are also provided. The method can be a one step acidic, iron catalyzed peroxide treatment process that can be incorporated into a single stage of a multi-stage bleaching process. The products can be chemical cellulose feedstocks, microcrystalline cellulose feedstocks, fluff pulps and products made from them.

Abstract: An absorbent material that can be used as an absorbent core in absorbent articles such as disposable diapers, feminine hygiene products and incontinence devices is provided. An absorbent material of this invention contains a blend of cellulosic fibers and a superabsorbent material. The absorbent material has superior wicking, strength and softness properties when compared to existing core materials. The material can be air-laid as a homogeneous blend of fiber and superabsorbent in one or more layers.
