Abstract: A method for manufacturing a laminated structure for use in an absorbent article such as a diaper, a sanitary napkin, a panty liner, an incontinence pad or similar and being defined by a plurality of material layers comprising at least a first layer which is liquid-permeable, a second layer constituting an absorbent core and a third layer, each of the layers being formed of a material having a certain pore radius. The method includes bonding together the material layers by means of at least two ultrasonic welding steps; and providing an ultrasonic welding pattern for each of the welding steps, each of the welding patterns being defined by a plurality of bonding sites. The method includes providing the welding steps for forming generally the entire absorbent article; and selecting the welding patterns in a manner so that at least the entire laminated structure has a multiple pore radius.

Abstract: The invention relates to an absorbent structure (3) for use in an absorbent article (1) and being defined by an airlaid material structure (3) being formed by a plurality of layers (3a; 3b; 3c; 3d) which are interposed between a liquid-permeable top sheet (2) and an absorbent core (4), said absorbent article (1) also comprising a backsheet (5) being of liquid-impermeable material. According to the invention, the absorbent structure (3) comprises a first layer (3a) having resilient synthetic fibers of at least approximately 5 dtex; that the absorbent structure (3) comprises a second layer (3b) having superabsorbent particles generally arranged as a distinct layer as opposed to being integrated within any other material of said absorbent structure (3); and that the absorbent structure (3) also comprises a treated fluff material having hydrophilic properties.

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.
