摘要：PROBLEM TO BE SOLVED: To provide a method for producing bleached pulp, enabling the amount of a bleaching agent necessary for bleaching pulp to desired whiteness to be markedly cut. SOLUTION: This method for producing bleached pulp comprises treating in a caustic oxidative bleaching process unbleached pulp obtained by cooking lignocellulose materials, followed by further treating the resultant unbleached pulp in a multistage bleaching process; wherein the caustic oxidative bleaching process is conducted using continuous two or more reactors.
