摘要：

Rice straw pulp has been bleached by a nonconventional four-stage method using organic solvents in the bleaching solutions. Methanol, ethanol, acetone, and dioxane, 10%, 30%, and 50% by volume were mixed with water as bleaching media in the first-stage process. Effects of kind and percentage of the organic solvent in the bleaching mixtures on the physical characterization of the bleached pulps and of the paper sheets were studied. Results are discussed on the basis of changing the physicochemical properties of the media by varying the solvent content in the bleaching mixture.
