Investigation and Comparison of Paper Properties of Birch and Aspen ‎CMP Pulp with the internal Beech and Horn Beam ‎

Document Type : Research Paper

Abstract

In this study the results showed that aspen has less fiber length than horn ‎beam and beech, fiber diameter and cell pit is more and cell wall thickness is ‎less. Furthermore, the diameter of the imported birch fibers is of the most ‎amount in the comparison of two types of beech and horen beam. The chemical ‎component of aspen and birch wood flour consists of the least Klason lignin and ‎the most holocellulose. The handsheet properties of CMP pulp of birch and ‎aspen showed that the bursting strength and breaking length which is more than ‎beech and horn beam. ‎
