  • Publication number: 20130231419
    Abstract: Processing of cellulose, and more particularly, fiber opening and downstream processing and chemistry are provided. A process includes moistening a cellulose sheet stock to a water content in a range from about 20% to about 50%, attriting the moistened cellulose sheet to a wet pulp, flash drying the wet pulp to a floccule of cellulose having a moisture content from about 4% to about 8%, and esterifying the floccule of cellulose to provide a cellulose ester product.

  • Publication number: 20130213596
    Abstract: A method regulating the formation of a fibrous web, such as a paper, cardboard, or tissue web, in which method the formation of the fibrous web is measured online as a controlled variable and is held at a predefinable setpoint level via automatic formation regulation. In addition to the formation, the charge concentration of the suspension is measured as a controlled variable and is taken into consideration during the formation regulation.

  • Patent number: 8512519
    Abstract: Sulfopolyester thermoplastic resins provide advantages in papermaking processes and in paper products including paperboard. Improvements in wet strength and dry strength of paper products are achieved by addition of sulfopolyester thermoplastic resins and cationic strength additives during the paper making process. The use of sulfopolyester thermoplastic resins in paper products also significantly enhances the repulpability of the paper.

  • Publication number: 20130206349
    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: 20130206350
    Abstract: The invention is directed towards methods and compositions for processes based on the combination of organic peroxyacids and ammonium salts that preserve and enhance the response to optical brighteners (fluorescent whitening dyes), brightness and improve color of pulp or paper when applied during different stages of the papermaking process are identified. The composition and method improve response to optical brighteners (fluorescent whitening dyes), maintain and/or enhance brightness and enhance the performance of paper products. Used in combination with optical brighteners the described agents produce a synergistic effect not previously identified in the paper process.
