Abstract:
Absorbent article, comprising an absorption body enclosed in a partially liquid-permeable cover, wherein the absorption body comprises absorption material comprising a carrier material coated with a thermosensitive polymer, which polymer exhibits a cloud point at a temperature about and somewhat below the body temperature of a healthy human being, whereby absorption properties of the polymer change at the cloud point so that the polymer substantially lacks absorption capacity at a first temperature on one side of the cloud point but exhibits absorption capacity at a second temperature on the other side of the cloud point, wherein the cover comprises a liquid-permeable layer and a liquid-impervious layer which are mutually connected around the absorption body, wherein the absorption body comprises a first absorption layer and a second absorption layer, the first absorption layer is arranged between the liquid-permeable layer and the second absorption layer, the first absorption layer consists essentially of a carrier material coated with a thermosensitive polymer, the second absorption layer is arranged closest to the liquid-impervious layer, and the second absorption layer consists essentially of absorbent material without thermosensitive coating.
