Abstract : The fibre stiffness cannot be measured by the Samuelson method on fibres shorter than approximately 1.5 mm, e.g. hardwood fibres or strongly beaten softwood and hardwood fibres. The fibre stiffness can, however, be calculated from the shear modulus of a fibre network by means of a semiempirical relationship. The work describes the results of this procedure for two beaten chemical pulps and for some different hardwood pulps. The values in the former case seem to be comparable with the stiffness for corresponding unbeaten pulps. The hardwood pulps, however, behave differently and the stiffness values can probably be compared only with one another. (Author)
