Abstract
The purpose of this work is to study the relationship between the drying stresses and internal stresses and the mechanical properties of paper.
An apparatus was designed to measure the drying stresses, moisture content and surface temperature during the drying of paper.
The internal stresses in paper were measured using the technique described by Kubdt et al.⁽¹⁻²⁾ The internal stress was found to be equal to the drying stress, independent of the structure of the sheet.
The results also show that the drying stress developed during restrained drying correlates strongly with the mechanical properties of the paper when different types of fibre are compared under the same drying conditions.
