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.

Modified cellulose from chemical kraft fiber and methods of making and using the same

This disclosure relates to methods of making novel dissolving wood pulps by processes comprising acid prehydrolysis, pulping, and a multi-stage bleaching process comprising oxidation with a catalyst and peroxide under acidic conditions, as well as to products made therefrom having a combination of medium-purity, low viscosity, and improved reactivity, filterability, and/or clogging that can be used as a substitute for traditional high-purity dissolving pulps in a wide variety of applications.

Dissolving wood pulps and methods of making and using the same

The present disclosure provides a composite of (a) oxidized cellulose comprising at least one carboxyl and (b) at least one component selected from a diamine, a diol, or mixture thereof. This disclosure further relates to methods of making such composite materials and suitable uses thereof, including in fibers, fabrics, textiles, films, fillers, packaging materials, plastics, etc.
