Abstract
The conventional two-stage H2O2 method was applied for bleaching rice straw and bagasse pulps. The pulps were bleached also by a nonconventi onal method: i.e., using different organic solvents with various conte nts in the first stage of the bleaching process. The effects of the ki nd and percentage of the organic solvent in the bleaching mixture on t he properties of both the bleached pulps and paper sheets were studied and are discussed on the basis of the physicochemical properties of t he bleaching mixtures.
