Bleaching aid and method for bleaching cellulose pulp |
| abstract |
PROBLEM TO BE SOLVED: To provide a bleaching aid having a high bleaching effect in a step of oxygen bleaching or ozone bleaching of cellulose pulp and obtaining sufficient whiteness. SOLUTION: The water-soluble polymer (A) having a solubility parameter of 14 to 24 and / or a 10-hour half-life temperature of 6 is used. A bleaching aid comprising a combination of a peroxide (D) at 0 to 170 ° C and a nonionic surfactant (B) and / or an anionic surfactant (C). |
