  • USE OF MODIFIED LIGNIN AS A WET END STRENGTH ADDITIVE
    Publication number: 20240344271
    Abstract: A method of increasing paper strength is provided. The method includes adding a lignin-based compound to a pulp slurry: and adding a cationic polymer to the pulp slurry. When added to a pulp slurry. the combination of a lignin-based compound and a cationic polymer produce a comprehensive paper strength increase.

  • USE OF AN ANIONIC ADDITIVE TO IMPROVE DRY STRENGTH COMPOSITION PERFORMANCE
    Publication number: 20240263400
    Abstract: Compositions and colloidal particles are provided that may be used to improve a papermaking process. The compositions and colloidal particles may include a cationic polymer, an inorganic salt, and an anionic component. A papermaking process carried out using the presently disclosed compositions and colloidal particles may produce a paper product that has increased strength properties.

  • STRENGTH IMPROVEMENT VIA SPRAYBOOM APPLICATION
    Publication number: 20230313467
    Abstract: The present disclosure provides methods and compositions for strengthening paper. The methods may include a step of spraying an anionic polymer onto a paper sheet to increase the strength of the paper sheet. The anionic polymer may have amino groups, amide groups, or a combination of amino groups and amide groups. These groups may be functionalized with an aldehyde. Methods may also include a step of adding a wet end composition to a wet end of the papermaking process.
