Presented by Gregory Perrine, Georgia-Pacific

In order to manufacture paper with the desired physical properties, various chemical additives are applied in the papermaking process. “Debonders” are one such chemical additive, leveraged to improve the softness of paper products by reducing the strength/stiffness of the paper.

To properly optimize the debonder formulation, a study needs to factor in the mixture components as well as the overall dosage to the papermaking process. Running this experiment using a one-factor-at-a-time approach would have required an impractical number of runs and testing. Fortunately, Design-Expert offers Kowalski-Cornell-Vining (KCV) mixture/process designs, which significantly reduce the number of runs required to study mixture components and the impact of process settings.

This presentation will discuss the use of a KCV mixture/process design to characterize and optimize a mixture system and the impact of dosage to handsheets. A commentary on how design of experiments has been advanced within Georgia-Pacific R&D will also be briefly discussed.
