Abstract

Bei einem Verfahren zum Beladen von in einer Faserstoffsuspension enthaltenen Fasern mit einem Hilfsstoff durch eine chemische Fällungsreaktion werden der Faserstoffsuspension vor der Auslösung der Fällungsreaktion Calciumhydroxid und/oder Calciumoxid und mindestens ein Bleichmittel zugesetzt. Dabei kann es sich bei dem Bleichmittel insbesondere um Peroxid handeln.
