Title (EN) COMPOSITION FOR IMPROVING THE RETENTION AND DRAINAGE IN THE MANUFACTURE OF PAPER
(FR) RETENTION ET EGOUTTAGE AMELIORES DANS LA FABRICATION DU PAPIER
Abstract:
(EN) A method of improving retention and drainage in a papermaking process is disclosed. The method provides for the addition of an associative polymer, a polyelectrolyte and optionally a siliceous material to the papermaking slurry. Additionally, a composition comprising an associative polymer, and a polyelectrolyte and optionally further comprising cellulose fiber is disclosed.
(FR) L'invention porte sur un procédé qui permet d'améliorer la rétention et l'égouttage lors d'un processus de fabrication de papier. Le procédé de l'invention consiste à ajouter un polymère associatif, un polyélectrolyte et, facultativement, un matériau siliceux à la pâte à papier. L'invention concerne en outre une composition comprenant un polymère associatif, un polyélectrolyte et, facultativement, de la fibre de cellulose.
