Abstract

We have studied the creep behavior of wet pilot papers made from both mechanical and chemical furnishes. Qualitatively the behavior looks similar to the one observed for dry sheets. However, more careful analysis reveals a kind of a transition in the dynamic creep behavior at moisture content where free water is expected to appear in the fiber network. Chemical furnish leads to higher creep rates than mechanical ones. We fitted the measured creep behavior to a dynamical rheology model based on the master-curve formalism. The model was used to extrapolate tension of a running web in the pilot-scale testing device. We found quite good agreement between the simulated and measured tension values.
