Utilization of a chemical-mechanical pulp with improved properties from poplar wood in the composition of packing papers
The aim of the present work is to obtain a chemical-mechanical pulp (CMP) from poplar wood with improved properties, to be used in packing papers in place of more expensive softwood or hardwood pulp. For improving the CMP quality indicators, a preliminary treatment of the pulp has been carried out w...

| description | The aim of the present work is to obtain a chemical-mechanical pulp (CMP) from poplar wood with improved properties, to be used in packing papers in place of more expensive softwood or hardwood pulp. For improving the CMP quality indicators, a preliminary treatment of the pulp has been carried out with a mixture of oxidizing enzymes produced from Phanerochaete chrysosporium, including lignin peroxidase, manganese peroxidase, and laccase. The two types of fiber materials obtained were double-stage bleached and then ground to 30oSR. It was found that preliminary enzyme treatment yielded CMP with improved physical, mechanical, and optical properties. The enzyme-pretreated CMP also refined faster, thus reducing the electricity consumption. Bleached CMP from poplar wood, obtained after preliminary enzyme treatment, could be successfully utilized at levels up to 40% in the composition of various packaging papers. |
