Tobacco stalks represent a type of abundant renewable resources. In the present study, tobacco stalks were treated by water at 60 °C for 100 min, to remove water-soluble matters, and then refined at concentrations of 20% (m/m), by refiner mechanical pulping (RMP). To obtain good fiber fibrillation, the pulp was beaten in a PFI mill. The fiber parameters were detected by Kajaani FS-300 and SEM. The analysis revealed that the length of the fibers was similar to that of non-wood material pulp, and

At a PFI mill revolution number of 3500 r (beating degree 33 o SR), the physical properties of paper reached the optimum values. The water permeability of the paper recommended it as a hydrophilic material suitable for subsequent papermaking processing. In conclusion, the properties of tobacco stalk pulp recommend it as a papermaking material.
