PULP AND PAPER PROPERTIES OF EUCALYPTUS MICROTHECA GROWN IN SOUTHERN REGION OF IRAN

In this study, anatomical, physical, pulping and paper making properties of Eucalyptus microtheca grown in Farse province is investigated. Eight trees were sampled for this study. The average dry and critical specific gravity of 8 samples were measured at 0.85 and 0.88 for heartwood and 0.8 and 0.75...
