Abstract
The shrinkage and drying behaviour of paper furnishes was
studied by examining the development of shrinkage and
tension in separate individual plies during drying in a
specially developed apparatus that can control restraint
and/or shrinkage. Experimental results show large
differences in dryness and drying stress/shrinkage
behaviour between chemical and mechanical furnish plies
throughout the drying process. In Part 2 of this study
the hypothetical shrinkage and drying behaviour of a
symmetric three-ply board was predicted using this
information together with simulated moisture and
temperature variations of such a board as it passes
through a typical cylinder dryer section.
