CHARACTERIZATION OF A.SEYAL VAR. SEYAL DEL. (TALH) AS A RAW MATERIAL FOR PULP PRODUCTION

In this study the morphological properties and chemical composition of A.seyal were determined and compared to other wood and non-wood materials, commonly used for pulp production, with the aim of assessing its potentials as a suitable raw material for pulp and paper production. Fiber length, Fiber width, lumen width and cell wall thickness of A.seyal were measured as 1.20 mm, 19.0µm, 13.8µm and 2.5µm, respectively. The value of Runkel ratio (0.91) was within the acceptable values (˂1) suitable for pulp and paper production. Fiber of A.seyal gave flexibility coefficient of 52.39 %, which classified them as elastic fibber and within the acceptable values for pulp production. Slenderness and rigidity values for A.seyal were calculated as, 122.8 and 0.47, respectively. The chemical analysis of A.seyal revealed the holocellulose as 76.8%, α-cellulose 47.25%, lignin 20.32%, and ash 1.80%. Based on the analysis of the morphological and chemical characteristics of A.seyal the fibbers of this species could be considered as suitable for pulp and paper production in Sudan.
