Abstract

L'invention porte sur un procédé qui permet d'effectuer un prétraitement d'une matière fibreuse broyée avec du carbonate de sodium et de cuire ensuite la matière prétraitée en présence d'anthraquinone (AQ). On obtient alors une pâte possédant un rendement plus élevé, une résistance améliorée et une meilleure aptitude au blanchiment, en comparaison avec les pâtes produites selon les procédés de l'état antérieur de la technique. On peut également introduire l'anthraquinone à l'étape du prétraitement au carbonate. Le procédé de l'invention peut également comprendre un prétraitement à l'acide qui permet d'encore améliorer les propriétés de la pâte produite.
