Abstract: An absorbent article comprises a liquid impermeable backsheet and an absorbent core. The backsheet is not overlaid by the core in at least one margin section. The article also comprises at least one ventilation component constituted by a ventilation material. Each ventilation component is positioned overlaying the backsheet and exclusively localized within one or more margin sections. The thickness of the ventilation material measured at 0.5 kPa is at least 1 mm. The porosity of the ventilation material is >80%. The ratio between the thickness of the ventilation material measured at 5 kPa and the thickness of the ventilation material measured at 0.5 kPa is >0.5. Each ventilation component is arranged such that an associated spacing is created between the wearer's skin and the backsheet when the absorbent article is worn.

Abstract: An absorbent porous structure for use in a diaper, a pant diaper, an incontinence guard, a sanitary napkin or the like, with a liquid acquisition portion and a liquid storage portion which are an integrated unit. The liquid acquisition portion comprises a compressed polymeric open-cell foam which expands upon wetting, and the liquid storage portion comprises a polymeric open-cell foam which may be the same or different from the foam in the liquid acquisition portion. The liquid storage portion also contains a superabsorbent material, with the amount of superabsorbent material being lower in the part of the liquid storage portion that is located closest to the liquid acquisition portion than in the part of the liquid storage portion that is located furthest from the liquid acquisition portion. Other embodiments include a method for producing the absorbent structure and an absorbent article containing such an absorbent structure.

Abstract: The invention refers to an absorbent structure in an absorbent article such as a diaper, a pant diaper, an incontinence guard, a sanitary napkin etc., the absorbent structure comprises an open-cell foam structure, the pore walls of said foam structure comprising a liquid-storing material having the capacity to store more than 7% synthetic urine defined according to the CRC method. The absorbent structure is characterized by that the pores of the foam structure contains hydrophilic fibers, at which at least the main part of the hydrophilic fibers are firmly anchored in the pore walls of the foam structure, and that the fiber amount is at least 10% by weight of the total weight of the open-cell foam in dry condition. The invention also refers to an absorbent article containing such an absorbent structure.

Abstract: The invention pertains to a foam material for absorption of aqueous liquids, a manufacturing method and an advantageous use of such a foam material, and an absorbent disposable article comprising such a foam material. The foam material is hydrophilic and primarily intended for use in absorbent disposable articles such as baby diapers, incontinence protectors and products for feminine hygiene. However, the foam material according to the invention is also suited for use in other absorbent articles, such as in different wiping materials, bandage materials and other similar products. The chemical structure of a surfactant, which is utilized as a combined emulsifying and hydrophilizing agent when manufacturing the foam material according to the invention, makes it possible to retain a sufficient proportion of the foam surfactant in the foam material even after repeated wettings, something which renders the foam material highly, permanently hydrophilic.
