Delignifying or lignin-removing bleaching Bleaching can basically be defined as a chemical process applied to chemical and mechanical pulps in order to increase their brightness.1 Thus, to reach an acceptable brightness level, bleaching should be performed either by removing the coloured residual lignin of chemical pulps (“delignifying or lignin-removing bleaching”) or by converting and stabilising
