Title (EN) METHOD OF PRODUCING ABSORBENT STRUCTURES WITH HIGH WET STRENGTH, ABSORBENCY, AND SOFTNESS
(FR) PROCÉDÉ DE PRODUCTION DE STRUCTURES ABSORBANTES PRÉSENTANT UNE RÉSISTANCE À L'ÉTAT HUMIDE, UNE CAPACITÉ D'ABSORPTION ET UNE SOUPLESSE ÉLEVÉES
Abstract:
(EN) A method of making an absorbent structure including forming a stock mixture of fibers, a cationic wet strength resin, an anionic polyacrylamide and a cellulase enzyme, and at least partially drying the stock mixture to form a web.
(FR) L'invention porte sur un procédé de production d'une structure absorbante comprenant la formation d'un mélange de pâte de fibres, d'une résine cationique à résistance à l'état humide, un polyacrylamide anionique et une enzyme de cellulase, et le séchage d'au moins partiel du mélange de pâte pour former une bande.
