APPLICATION OF COMPUTER IMAGE ANALYSIS FOR CHARACTERIZATION OF VARIOUS PAPERMAKING PULPS

摘要

Laboratory-prepared bleached kraft pulps, made from wood of different tree species, and industrial neutral sulphite semichemical (NSSC), chemithermomechanical (CTMP) and groundwood pulps were studied by the computer image analysis method. The number of fibres in a mass unit of pulp, the relative content of fines and also the morphological fibre properties were determined. The obtained results were discussed and compared.
