Title
(EN) ABSORBENT STRUCTURE CONTAINING INDIVIDUALIZED CELLULOSIC FIBERS CROSSLINKED WITH POLYACRYLIC ACID POLYMERS
(FR) STRUCTURE ABSORBANTE RENFERMANT DES FIBRES CELLULOSIQUES INDIVIDUALISEES RETICULEES PAR DES POLYMERES A L'ACIDE POLYACRYLIQUE
Abstract
(EN)
Disclosed are individualized, crosslinked fibers, and processes for making such fibers, and absorbent structures containing the fibers. The individualized, crosslinked fibers have a polymeric polyacrylic acid crosslinking agent reacted with the fibers in the form of intrafiber crosslink bonds. Preferably, the crosslinking agent is a copolymer of acrylic acid and maleic acid and preferably, between about 1.0 weight % and about 10.0 weight % of the crosslinking agent reacts with the individualized fibers to form the intrafiber crosslink bonds. The individualized, crosslinked fibers are useful in a variety of absorbent structure applications. The absorbent structures may also contain hydrogel-forming material.
(FR)
L'invention se rapporte à des fibres réticulées, individualisées, à leurs procédés de fabrication, et aux structures absorbantes renfermant ces fibres. Les fibres réticulées, individualisées, possèdent un agent de réticulation d'acide acrylique polymère qui a réagi avec les fibres sous forme de liaisons de réticulation intrafibres. L'agent de réticulation est de préférence un copolymère d'acide acrylique et d'acide maléique, et de préférence, entre environ 1 % et environ 10 % en poids de l'agent de réticulation réagit avec les fibres individualisées pour former les liaisons de réticulation intrafibres. Les fibres réticulées individualisées sont utilisées dans une variété d'applications de structures absorbantes. Les structures absorbantes peuvent également contenir une matière formant un hydrogel.
