| abstract | (57) [Abstract] [PROBLEMS] To economically and efficiently produce paper with high whiteness. Hydrogen peroxide as a bleaching agent is added to the pulp slurry before the beating step. The hydrogen peroxide is preferably added during disaggregation. Further, the hydrogen peroxide is 0.5 to 100 parts by weight based on the absolute dry weight of the pulp. It is preferable to add 2.0 parts by weight. Further, it is preferable to disintegrate a pulp slurry having a pulp concentration of 6 to 8% and a pH of 8 to 11 at a temperature of 35 to 60 ° C. for 1 hour or more after the hydrogen peroxide is added. |
