Abstract

Afin d'améliorer l'égouttage et par conséquent la vitesse de la machine lors de la fabrication de papier ou de carton à partir de papier recyclé, on ajoute une enzyme hydrolysant l'amidon (une alpha-amylase) avant le passage de la pâte dans la section de formation de la feuille. Cette enzyme doit être active dans une plage de températures se situant entre 40 et 90 ·C et dans une gamme de pH comprise entre 6 et 9. Des quantités enzymatiques pondérales aussi faibles que 0,05 % du poids du papier séché à l'étuve et formant la pâte permettent d'augmenter les vitesses de la machine d'au moins 5 % ou davantage.
