Evaluation of the quality of cellulose for chemical processing

The species composition of cellulose from sulfite and sulfate methods of delignification manufactured by Kotlassk Pulp and Paper Combine and Baikal Cellulose Paper Combine was analyzed by a microscopic method. It was shown that an increase in the content of larch and deciduous wood fibres in cellulose decreases the capacity of cellulose for chemical processing in the viscose plant and the quality of the finished textile fibre. It was found that addition of deciduous and larch wood in production of cellulose for chemical processing by both the sulfite and sulfate methods of delignification is extremely undesirable.
