Abstract
La présente invention concerne un procédé de fabrication d’une feuille de papier ou de carton à partir d’une suspension fibreuse, comprenant les étapes suivantes :a) injection d’un polymère P3 dans une suspension de fibres cellulosiques,b) formation d’une feuille de papier ou de carton,c) séchage de la feuille de papier ou de carton,le polymère P3 étant préparé, préalablement à l’étape a), à partir d’un polymère hydrosoluble P1 d’au moins un monomère non ionique choisi parmi l’acrylamide, le méthacrylamide, le N,N-diméthylacrylamide, et l’acrylonitrile,le polymère P1 étant soumis à une réaction Re1 pour donner un polymère P2, lequel est soumis ensuite à une réaction Re2 pour donner le polymère P3, lequel est injecté à la suspension fibreuse dans un délai de 24 heures par rapport au début de la réaction Re1,- la réaction Re1 consistant à préparer un polymère P2 comprenant des fonctions isocyanate par réaction pendant 10 secondes à 60 minutes entre (i) un hydroxyde d’alcalin et/ou un hydroxyde d’alcalino-terreux, (ii) un hypo-halogénure d’alcalin et/ou un hypo-halogénure d’alcalino-terreux et (iii) le polymère P1,- la réaction Re2 consistant à préparer un polymère P3 par réaction entre (iv) un composé de micro cellulose et (v) le polymère P2 comprenant des fonctions isocyanate.
