Abstract

In this study, pulp and handsheets characteristics of radiata pine wood kraft pulp was evaluated. The ratiata pine wood was collected from Chamestan Noor Research Station. Average dry and basic specific gravity of wood were determined as 0.342 and 0.308 g/cm3 and average fiber (tracheid) dimension including fiber length, fiber diameter, lumen diameter and cell wall thickness were measured as 2460, 40.35, 33.17 and 3.59 mm, respectively. The chemical composition was determined as holocellulose 72.07%, alfa cellulose 43.41%, lignin 29.95%, ash 0.50 % and extractive as 1.75%. Kraft (Sulfate) process was applied for cooking and pulping the wood. A factorial randomized complete block design test was conducted to compare the fiber dimensions, physical properties, chemical composition and the yield of the pulp. To examine strength properties of handsheets, ANOVA statistical analysis was used and for grouping the means Duncan test were applied. The minimum and maximum yield and KAPPA NUMBER of these pulps were measured at 40.33%, 50.43% and 33.89, 60.22, respectively. The results of handsheet strength measurement indicated that radiata pine wood kraft pulp provides suitable substitute for imported long fiber pulp to be mixed with short fiber hardwood pulp.
