Abstract:Microfibres with different length were prepared from BSKP and their effects on the physical properties(tensile strength, bulk and softness) and drainage of reconstituted tobacco sheets were studied. The results showed that microfibres with longer length and higher dosage had better paper-strengthening effect. At the same time, the bulk, softness and drainage were affected negatively. When the dosage of wood fibers was 15% and the average length of microfibers was 0.622 mm, the physical properties of tobacco sheet was improved effectively. The suitable dosage of micrifibres was 1.5%. Compared with the traditional process, the wood fiber amount used in the new process reduced by 25%.
