Abstract
A study was made on the dynamic press simulator to determine the pressability differences of once dried pulps and ·never dried pulps. As water is removed in the drying process, nearly all of the water-to-cellulose bonds are replaced by cellulose-to-cellulose bonds. Rewetting the dry pulp reestablishes only part of the water-to-cellulose bonds. Therefore, at the same moisture content the once dried pulp holds its water 'looser' than the never dried pulp. The results prove that previously dried pulps reach higher consistencies in the press section than pulps that have never been dried. The results also indicate that the dynamic press simulator used for this study should be perfected prior to continued study.
