Abstract

Never-dried pine sulphate paper grade pulp was treated with specific enzyme mixture from Trichoderma reesei, which increased the alkaline solubility of pulp from 20% to 69% and decreased the DPW from 1124 to 622. The effect of different viscose process additives and zinc oxide on solubility was studied. The best combination for producing a good spinning dope was chosen. The fibres were spun using a wet spinning machine and titre, tenacity and elongation of the fibres were determined. The strongest fibres obtained have tenacity of 1.2 cN/dtex and elongation of 12-13%, which are comparable to the properties of cotton.
