Embodiments of the invention relate to a modifying agent for making cellulosic based acquisition fibers in the sheet form, the modifying agent being the reaction product of a polycarboxylic acid compound and a polyfunctional epoxy compound. A method of producing the cellulosic based acquisition fiber in the sheet from using the modifying agent includes treating the cellulosic fibers in the sheet form with the modifying agent, and drying and curing the treated sheet to promote the formation of intra-fiber bonding. The resultant cellulosic based acquisition fiber may be utilized in an acquisition layer and / or an absorbent core of an absorbent article.
L'invention concerne, selon des modes de réalisation, un agent modifiant permettant de produire des fibres d'absorption à base cellulosique sous la forme de feuilles, l'agent modifiant étant le produit de la réaction d'un composé d'acide polycarboxylique et d'un composé époxydique polyfonctionnel. L'invention concerne un procédé de production de la fibre d'absorption à base cellulosique sous la forme de feuille utilisant l'agent modifiant, consiste à traiter les fibres cellulosiques sous la forme de feuille par l'agent modifiant, et à sécher et durcir la feuille traitée afin de favoriser la formation de liaison à l'intérieur de la fibre. La fibre d'absorption cellulosique résultante peut servir dans une couche d'absorption et/ou un noyau absorbant d'un article absorbant.
