  • Patent number: 9777432
    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.

  • Publication number: 20160032494
    Abstract: High permeability curly fibers with enhanced fiber strength are produced by mercerizing cellulosic fibers. The fibers have relatively high values for curl, kink level, wet tensile strength, and bulk density when compared with current fibers. The disclosed fibers can be used in a wide range of applications including paper products such as filters.
