Abstract

To stay competitive, a more efficient utilization of fiber material is needed in the future, because new types of fibers are taken to use from biorefineries, and new fiber applications are developed, for example, new methods for forming fiber networks, use of fibers in reinforcing bioplastic composites etc. Therefore better and more versatile characterization methods are needed better to understand the processability of pulps, changes in pulps during the process, and to get a deeper understanding of the factors affecting paper, board and composite properties. The available commercial fiber analyzers enable statistically significant measurements with little manual work and provide a huge number of parameters per measurement. In addition to average values, also parameter distributions are obtained. In this study, 14 different pulps including chemical pulps, mechanical pulps and recycled fibers were measured with three fiber analyzers - FiberMaster, kajaani FiberLab and kajaani FS300. Only the fiber length results were very close, other parameters differed considerably. To find more about the measurement potential of these devices, microscopic images together with fiber analyzer data were used to identify the characteristic features of those pulps with focus on property combinations as 2D- and 3D distribution maps. Finally, PLS analysis of the measured fiber characteristics was done to find an explanation for the drainage behavior from fiber properties. The results being presented ended up that a possible parameter combination to characterize a certain pulp should include from the available parameter pool at least the length-weighted fiber length, the proportions and character of fines (<200 µm), near-fines (200-500 µm), and short fibers (500-1200 µm), the fiber width, and the coarseness or basis weight of the fibers (coarseness/width). For a closer estimation of pulp or paper properties, additional parameters would be included
