DETERMINATION OF PRACTICAL PROPERTIES OF ALNUS GLUTINOSA GROWN AT SHORT ROTATION PERIOD IN PAPER MAKING

In this investigation, physical, chemical, fiber dimensions, pulp and papermaking characteristics of 4 years old Alnus glutinosa was researched. The average of oven dry and critical density, fiber length, fiber diameter, lumen diameter and cell wall thickness were measured at 0.396, 0.368, 0.875mm,...
