Method for controlling viscosity in dissolving pulps |
| abstract |
The present invention relates to an improved process for producing dissolving pulp from a sulfite cooking process using a TCF bleaching sequence containing alkali extraction and alkaline peroxide bleaching in the pulp bleaching. The new process adds an acidic peroxide stage (Pacid) which makes it possible to control pulp viscosity in an efficient way and do not introduce new bleaching chemicals into the filtrate handling system. |
