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.
