Abstract
A dehydratable hygiene article contains a lower layer which is impermeable to aqueous liquids, an upper layer which is permeable to aqueous liquids, a core disposed between the lower and upper layer and absorbs aqueous liquids, and a trigger system containing a superabsorbent material which is capable of absorbing aqueous liquids with the formation of a hydrogel. 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 a hydrogel. The hygiene article contains at most 50 wt. % of a further superabsorbent material. Based on the total weight of superabsorbent material and further superabsorbent material, which would be capable, after the trigger system has been activated, of at least partly absorbing, with the formation of hydrogel, the aqueous liquid which is at least partly released.
