Patent ID: 8710292

Claim:
A dehydratable hygiene article, comprising: a lower layer being impermeable to aqueous liquids; an upper layer being permeable to the aqueous liquids; a core disposed between said lower layer and said upper layer for absorbing the aqueous liquids; a trigger system having a superabsorbent material capable of absorbing aqueous liquids when transforming to a hydrogel, wherein after the trigger system has been activated, at least some of the aqueous liquid absorbed can be released from the superabsorbent material when it is present as said hydrogel; and at most 50 wt. % of a further superabsorbent material, based on a total weight of said superabsorbent material and said further superabsorbent material, which would be capable, after said trigger system has been activated, of at least partly absorbing, with the formation of said hydrogel, the aqueous liquid being at least partly released and only after a further trigger system differing from said trigger system has been activated, at least one of said trigger system and said further trigger system changing said superabsorbent material and said further superabsorbent material to have reduced absorbency capabilities to allow the aqueous liquid to be drained out from the dehydratable hygiene article thus allowing the dehydratable hygiene article to be further compressed for an extraction of more of the aqueous liquid resulting in the dehydratable hygiene article having a reduced volume.
