Abstract

The paper presents quantitative characteristics of deformation behaviour at stretching for pulp-and-paper samples with different fiber composition at various ranges of humidity similar to the state of the material in the drying part of paper machine. It is established that lower moisture content of the material, in addition to increasing durability of samples, also improves rigidity and viscoelasticity.
