| description | A method of making paper or paperboard is described, which includes introducing at least one charged starch, preferably having a degree of substitution greater than 0.045, and at least one optical brightening agent to a papermaking pulp and then forming the pulp into paper or paperboard. The present invention further describes methods of improving optical brightener performance.
L'invention concerne un procédé de fabrication de papier ou de carton. Ce procédé consiste à introduire dans une pâte à papier au moins de l'amidon chargé, présentant de préférence un degré de substitution supérieur à 0,045, et au moins un azurant optique, puis à transformer la pâte en papier ou en carton. L'invention concerne en outre des procédés pour améliorer l'efficacité des azurants optiques. |
