Abstract

The experimental material in this study was poplar wood P. x euramericana (cl. I-214, cv. Robusta), P. deltoides (cl. 457, cl. 618 and cl. 725). The analyses referring to semichemical and sulphate pulp production were performed in laboratory conditions, while the analyses of groundwood mechanical pulp were carried out at full industrial scale. The yield, chemical properties and physical-mechanical characteristics of fibers intended for papermaking purposes were determined This paper presents the structural, physical, mechanical and processing properties, of wood (of 12 to 24 years old trees) of the same poplar clones intended to the manufacture of peeled veneer from the logs of this clones. The assessment of the utilization percentage and the share of full veneer sheets were determined.The obtained results confirmed the significance of poplar wood as a raw material for chemical and mechanical processing.


Keywords: poplar, wood properties, groundwood pulp, semichemical pulp, sulphate pulp, peeled veneer
