Latest Patents
Stephanie Keen holds a patent for a process titled "Process for using a phloroglucinol color delta to control blending, deinking and bleaching of groundwood-containing secondary pulp." This method involves characterizing the initial color of pulp and the color after treatment with a phloroglucinol stain. The color response of the pulp to the stain serves as a better indicator of processing needs for secondary pulps. This process is particularly effective for untreated groundwood, offering a more selective identification method compared to conventional techniques. The color difference aids in targeting suitable products for the pulp, optimizing bleaching and deinking strategies, and enhancing fiber blending for specific products. In a preferred embodiment, the process includes determining changes in CIE L*, a*, b*, and brightness values before and after staining the pulp.
