Abstract
L'invention porte sur une composition de matière et sur un procédé, qui permettent d'améliorer le procédé de mise en pâte mécanique de précurseurs de papier. La composition de matière comprend une petite quantité d'un agent réducteur et d'une source d'alcali. Lors de l'addition à la matière mise en pâte, par exemple, aux copeaux de bois, avant ou pendant la mise en pâte mécanique, la composition permet de réduire le coût énergétique de l'opération. De plus, non seulement la composition ne réduit pas la brillance de la pâte, mais encore la composition peut également augmenter l'efficacité des procédés de blanchiment ultérieurs.
