摘要： An absorbent product includes a nonwoven material arranged to be in contact with skin of a user during use of the absorbent product. The nonwoven material includes, at least on a skin contacting surface, a mixture of non-absorbent and absorbent fibres. The absorbent fibres are present in an amount of 2-30% by weight, or about 2-10% by weight, based on the total weight of the fibres in the nonwoven material. The non-absorbent fibres have a coarseness of 1.8 to 10 dtex and the absorbent fibres have a coarseness of 1 to 10. Also disclosed is a use of a nonwoven material in an absorbent product to reduce wet friction between the nonwoven and skin of a user.

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： 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 consisting of a second material. The receding wetting angle υr 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： An absorbent article comprising a breathable backsheet material layer wherein at least parts of said layer comprises 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 will involve an abrupt change of the permeability of the breathable material layer.

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： Absorbent product includes a nonwoven material arranged to be in contact with skin of a user during use of the absorbent product. The nonwoven material includes non-absorbent and/or absorbent fibres. The fibres, at least on a surface arranged to be in contact with skin of a user during use of the absorbent product, have a coarseness of from 0.1 to 10 dtex, or from 0.5 to 7 dtex. The fibres and/or the nonwoven material is coated with a lubricating coating composition suitable for use in absorbent and/or hygiene products at least on a surface arranged to be in contact with skin of a user during use of the absorbent product. By the product including the nonwoven, wet friction can be reduced between the nonwoven and the skin of the user.
