Evaluation of the Paper-forming Ability of Cellulose from Miscanthus Giganteus

Two methods for obtaining cellulose from Miscanthus giganteus based on sequential treatment of raw materials with dilute solutions of sodium hydroxide and nitric acid to obtain pure cellulose and cellulose with a residual pentosan content of 11% were developed. The papermaking ability of pure cellulose and cellulose with pentosans was analyzed and the latter showed a significant increase in breaking length, bursting resistance and deformation parameters. It was found that the addition of 5 and 15 % bacterial cellulose to pure cellulose increases the papermaking properties of the composition, while the addition of 5, 10 and 15 % bacterial cellulose to Miscanthus cellulose reduces the air permeability of the blended paper by 1.4, 2.0 and 2.8 times, respectively.
