Resum
The importance of HexA groups lies on their influence on the bleaching process and the properties of the resulting pulp. In this work, various aspects of HexA were examined in order to elucidate their role in eucalyptus fibres. Thus, the contribution of HexA to kappa number in eucalyptus pulp was estimated to be 1.05 units per 10 µmol of HexA. Also, HexA changes during an ECF and a TCF sequence were examined in relation to lignin. Interesting results were found by comparing the boosting effect ...
