Abstract: Urine absorbing devices having a modified kraft pulp fiber with unique properties is provided. The kraft fiber is made from a method having at least one acidic, iron catalyzed peroxide treatment process that can be incorporated into at least one stage of a multi-stage bleaching process. The products can be diapers, incontinence products and other urine absorbing devices.

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.
