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.

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.

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.
