Abstract

L'invention concerne un procédé permettant d'améliorer la résistance à la traction à l'état humide d'une bande continue cellulosique, consistant à préparer une composition de fabrication renfermant un matériau cellulosique et de l'eau, à ajouter un agent tensio-actif à ladite composition et à ajouter, à cette composition, après addition de l'agent tensio-actif, une résine conférant une résistance à l'état humide. Dans certains modes de mise en oeuvre, l'agent tensio-actif comprend un alkyl sulfate ou un alkyl sulfonate. Le procédé permet d'obtenir une bande continue cellulosique améliorée présentant un rapport résistance état humide/état sec amélioré.
