Abstract

Within this research activity unbleached softwood kraft pulp was refined with a lab scale disc refiner and a PFI-Mill by use of different refining intensities. After refining, the fines fraction was separated by a lab scale pressure screen. For each refining configuration and intensity hand sheets were built with and without fines to obtain values for the breaking length. Thereby it was possible to calculate and quantify the tensile gain achieved on one hand by secondary fines and on the other hand by internal and external fibrillation of the fiber itself.
