Fiber and Paper Properties Changes in Relation to age of Black Pine

Abstract

In this study, among the morphological properties of the Anadolu black pine (Pinus nigra Arn. ssp. pallasiana var. yaltirikiana) tracheid length, tracheid diameter, lumen length and double wall thickness were investigated depending on its age. In order to determine the importance of the fiber properties according to the age of the tree in terms of papermaking; elasticity ratio, felting ratio, runkel classification, rigidity coefficient, Muhlstep classification and F factor were calculated. As a result, it was determined that fiber length of the P. nigra increases from the pith towards to the bark depending on the age and this increase was significant statistically. Morphological characteristics of the Anadolu black pine are similar to those of softwood fibers. It's obvious that as the age of the wood increases, on the other hand, it is understood that paper formation and homogeneity of paper may be diminished.
