NSSC PULPING OF MISCANTHUS GIGANTEUS AND BIRCH WOOD PART 2: A COMPARISON OF PAPERMAKING POTENTIAL AND STRENGTH PROPERTIES

摘要

In this paper we compare the anatomical features (number of fibrous elements in the pulp unit, fiber length, diameter of fibers and lumens, coefficients of slenderness, flexibility and the Runkel coefficient) of both Miscanthus giganteus and birch wood. The raw materials were tested prior to pulping, after pulping and after refining. Comparisons of defibering ability and selected strength properties (CMT, SCT, tear resistance, burst) allowed evaluating the papermaking potential of neutral sulfite pulps obtained from the above-mentioned raw materials.
