In this papermaking process, a first strength agent is added to a stock suspension containing pulp and optionally other additives prior to its being formed into a web at the wet end of a papermaking machine. The web is then formed and processed into paper. A second strength agent is then applied to the surface of the paper. The strength agents may be selected to have opposite charge.
Ce procédé de fabrication de papier consiste d'abord à incorporer un premier agent de résistance, et éventuellement d'autres additifs, à la pulpe en suspension avant de lui donner la forme d'une bande dans la partie humide de la machine à papier. La bande est ensuite formée et traitée pour obtenir du papier. Un second agent de résistance est ensuite appliqué à la surface du papier. Les agents de résistance peuvent être choisis avec des charges opposées.
