ABSORBENT STRUCTURE HAVING IMPROVED LIQUID PERMEABILITY

Disclosed is an absorbent structure containing hydrogel-forming polymeric material, wettable staple fiber, and wettable binder fiber. The absorbent structure exhibits improved z-direction permeability of a liquid as compared to an otherwise essentially identical absorbent structure which does not co...

Beschreibung
Zusammenfassung:	Disclosed is an absorbent structure containing hydrogel-forming polymeric material, wettable staple fiber, and wettable binder fiber. The absorbent structure exhibits improved z-direction permeability of a liquid as compared to an otherwise essentially identical absorbent structure which does not comprise a wettable binder fiber. Also disclosed is a disposable absorbent product containing such an absorbent structure. L'invention présente une structure absorbante contenant un polymère constituant un hydrogel, des fibres discontinues et des fibres liables, mouillables. Cette structure absorbante fait preuve d'une perméabilité à direction Z, à un liquide, améliorée par rapport à celle d'une autre structure absorbante, par ailleurs pratiquement identique, mais dépourvue de fibres liables mouillables. L'invention présente également un article absorbant jetable comprenant cette structure absorbante.
