Patent number: 11111628Abstract: 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.Type: GrantFiled: July 20, 2020Date of Patent: September 7, 2021Assignee: GP Cellulose GmbHInventors: Arthur J. Nonni, Charles E. Courchene, Christopher Michael Slone, Peter R. Abitz
