Title: **Danielle Gagne: Innovator in Papermaking Technology**
Introduction
Danielle Gagne, an accomplished inventor based in Pierrefonds, Canada, has made significant contributions to the field of papermaking technology. With two patents to her name, her work focuses on enhancing the efficiency and performance of filler slurries used in the papermaking process.
Latest Patents
Danielle's latest inventions include innovative latex-treated filler slurries designed for use in papermaking. Her patent describes a filler treatment process that enhances the fixation of anionic latex on filler in a remarkably short time. In this process, anionic polymer dispersions (latex) are added to papermaking filler slurries at ambient temperatures and then mixed with water that exceeds the glass transition temperature (Tg) of the latex. This method ensures that the anionic latex is completely and irreversibly fixed onto the filler particles, resulting in an aggregated filler slurry that remains stable over time. This latex-treated filler slurry can be integrated into papermaking furnishes before the headbox of the paper machine or stored for future use. The process not only improves filler retention but also minimally affects sheet strength while enhancing sizing performance.
Another patent from Danielle details a continuous filter treatment process where the same types of anionic polymer dispersions are employed. The key to this method is maintaining the temperature of the filler/latex mixture significantly higher than the Tg of the latex, ensuring effective fixation. The specifications regarding the resin's chemical composition and the surfactant type during emulsion polymerization play crucial roles in optimizing the treatment process and improving the overall properties of the resulting paper.
