    摘要: An absorbent, porous structure (4), intended for use in an absorbent article, wherein the structure (4) exhibits a first region (19), primarily consisting of a first material, which stands in direct connection with a second region (20), primarily conssisting of a second material. The receding wetting angle &thgr;r is larger for the first material than for the second material, whereby liquid transport between the two regions (19, 20) takes place in a direction from the first region (19) to the second region (20), at least when the porous structure (4) is wet.

    摘要: The invention relates to an absorption material (50; 60) comprising a carrier material exhibiting a coating (51; 61) of a thermosensitive polymer with a cloud point at a temperature in the vicinity of and somewhat below the body temperature of a healthy human being. The 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 good absorption properties at a second temperature on the other side of the cloud point. Furthermore, the invention includes an absorbent article such as a diaper, an incontinence protector, a sanitary napkin, or the like, having an absorption body comprising an absorption material coated with a thermosensitive polymer.

    摘要: The invention concerns an absorbent article such as a diaper, an incontinence product, a sanitary napkin, a panty liner or the like, wherein one or several parts (103,203: 104,204: 105,205) of said article comprise elastic means (116,216: 117,217; 119,219) which hold a skincare agent in their structure. The skincare agent is arranged to be released when the elastic means (116,216: 117,217; 119,219) is stretched during use of the absorbent article and the elastic means (116,216: 117,217; 119,219) absorbs less than 20% water or urine

    摘要: An absorbent article includes a breathable backsheet material layer. At least a part of the layer includes a polymeric material exhibiting a discontinuous change in free volume in response to any of the following conditions or variables: liquid contact, the presence of certain ions, temperature and/or pH. One example of such polymeric materials is side chain liquid crystalline polymers which are able to undergo a phase transition between an isotropic phase and a nematic phase. The discontinuous change in free volume involves an abrupt change of the permeability of the breathable material layer.
