Summary: | The invention provides methods and compositions for increasing the strength of a paper sheet. The method involves adding to the paper sheet an amine containing polymer. The amine containing polymer interacts with materials such as GPAM or starch to make the paper stronger in terms including tensile strength, surface strength and bulk strength.
La présente invention concerne des procédés et des compositions permettant d'améliorer la résistance d'une feuille de papier. Le procédé comprend l'adjonction à la feuille de papier d'un polymère contenant de l'amine. Le polymère contenant de l'amine interagit avec des matières telles que du GPAM ou de l'amidon pour rendre le papier plus résistant, y compris en termes de résistance à la traction, de résistance de surface et de résistance globale. |
