Abstract

It has been proposed and approved to further delineate the effects that wet pressing plays on the migration pattern of a sizing element. As of this time, no in-depth study has been performed to further understand this principle, therefore the need for this research is crucial to possibly save the paper industry capital in the future.

Research was conducted to determine the ·effects that the wet pressing load had on the amount of size necessary for acceptable limitations. To accomplish this, the variables were held constant with the exception of the pressure applied to the sheet and the moisture content of the pre-sized base sheet. The sheet was then cross-sectioned and examined for size migration using image analysis.

The results gathered from this experiment supported the belief that as the wet pressing load was increased, the depth of size migration was decreased. This result, along with that of increased savings generated from higher wet press solids, will no doubt benefit the paper industry as a whole.
