Abstract

Die Erfindung betrifft ein Verfahren zum Bleichen von Faserstoffen, insbesondere von ligninhaltigen Faserstoffen für die Herstellung von Papier. Das Verfahren beinhaltet die Zugabe von wenigstens einem ersten Additiv und wenigstens einer Bleichlauge in die Faserstoffsuspension, wobei die Bleichlauge wenigstens ein Bleichagens aufweist. Nach dem Vermischen der Bleichlauge mit der Faserstoffsuspension und nach einer vorgegebenen Bleichdauer wird der Bleichprozess durch die Zugabe von wenigstens einem zweiten Additiv beendet. Das Verfahren ist ferner dadurch gekennzeichnet, dass die pH-Werteinstellung der Faserstoffsuspension durch die Zugabe von Kalk erfolgt.
