| titleOfInvention | Pulp bleaching method |
| abstract | PROBLEM TO BE SOLVED: To obtain a pulp with high whiteness by improving the efficiency when chlorine dioxide or chlorine bleaching is performed after acid treatment of pulp in multistage bleaching of pulp, or the total of bleaching chemicals Reduce usage. SOLUTION: In a multi-stage bleaching step including acid treatment, the starting pH of chlorine dioxide bleaching after acid treatment of pulp is neutral to weakly alkaline, specifically pH 5 to 10, more preferably pH 6 to 9. Can improve each bleaching efficiency. |
