Patent

CA 2356651

Disclosed are absorbent structures including fibers bound with a polyvalent cation-containing compound and superabsorbent polymer particles. The fibers exhibit an ion extraction factor of at least 5 %. Also disclosed are multi-strata absorbent structures, such as disposable absorbent articles, including the treated fibers and SAP particles. Further disclosed are methods for preparing absorbent structures including the treated fibers; structures including fibers combined with a polyvalent cation-containing compound; and methods for treating or coating SAP particles with polyvalent cation-containing compounds.

Cette invention se rapporte à des structures absorbantes comprenant des fibres liées avec un composé contenant des cations polyvalents, ainsi que des particules de polymère superabsorbant (SAP). Ces fibres possèdent un facteur d'extraction ionique d'au moins 5 %. Cette invention se rapporte également à des structures absorbantes multicouches, telles que des articles absorbants jetables, comprenant ces fibres traitées et ces particules de SAP; ainsi qu'à des procédés servant à préparer des structures absorbantes contenant ces fibres traitées; à des structures renfermant des fibres combinées à un composé contenant des cations polyvalents; et à des procédés servant à traiter ou à enduire des particules de SAP avec des composés contenant des cations polyvalents.
