Title (EN) A METHOD TO FORM A WEB COMPRISING FIBERS
(FR) PROCÉDÉ DE FORMATION D'UNE BANDE COMPORTANT DES FIBRES
Abstract:
(EN) The invention discloses a method to enable the efficient use of surfactants in web forming of a cellulose containing material, e.g. in the making of paper or paperboard. The method comprises the addition of microfibrillated cellulose (MFC) or nanocrystalline cellulose (NCC) to the white water in a web-forming process in order to form complexes with surface active agents. The formed complexes are at least partly recycled to the process. This enables the producer to have control over the concentration of surface active agents in the system.
(FR) L'invention concerne un procédé qui permet l'utilisation efficace de tensioactifs dans la formation de bande d'un matériau contenant de la cellulose, par exemple dans la fabrication de papier ou de carton. Le procédé comprend l'ajout de cellulose microfibrillée (MFC) ou de cellulose nanocristalline (NCC) à l'eau blanche dans un procédé de formation de bande afin de former des complexes avec des agents tensioactifs. Les complexes formés sont au moins partiellement recyclés vers le processus. Ceci permet au producteur d'avoir une commande sur la concentration d'agents tensioactifs dans le système.
