cze	Displacement Washing of Pulp with Solutions of Cationic Polyacrylamides in Water	Using distilled water and/or aqueous cationic polyacrylamide solutions, the mechanism of the displacement washing of unbleached kraft pulp was investigated. The step change technique has been employed in the investigation of displacement of black liquor. To characterize such a phenomenon, the washing curves, as well as wash yield at the wash liquor ratio equal to unity were determined. The results obtained for pure wash water were compared with those for polyacrylamide solutions. Laboratory results have indicated that improved displacement washing can be achieved by the addition of high molecular weight cationic polyacrylamides to the wash water.
