Abstract : Changes in a number of mechanical parameters of four machine-made paper grades when treated with water and dried without constraint (release of internal stresses) are reported. The results are discussed in terms of an internal stress parameter obtained from stress relaxation measurements. There was no general relationship between this parameter and the various mechanical properties measured. The anisotropy of the sheet, defined in terms of the tensile strength or the modulus, unexpectedly changed to only a small extent when the internal stresses were released by the water treatment.
