Abstract: A material laminate (1) with a planar dimension and a thickness direction perpendicular to the planar dimension, comprises a first liquid-permeable fibrous material layer (2) and a second liquid-permeable, porous and resilient material layer (3), with at least one of the material layers (2, 3) including thermoplastic material and the two material layers (2, 3) being mutually connected by the material laminate (1) exhibiting bonding sites (4) within which the thermoplastic material has been caused to at least partially soften or melt and thereby bond together the two material layers (2, 3). The bonding areas are arranged in two or more groups (5) with at least two bonding sites (4) in each group (5), with the greatest relative distance between two bonding sites (4), which are situated adjacent to each other, in a particular group (5) being less than the shortest distance between the group (5) and its closest adjacent group (5), as a result of which the material laminate (1) exhibits bond-free areas (6) between the bonding sites (4) within each bonding group (5) which have a higher density than bond-free areas (9) of the material laminate which are situated between the bonding groups (5). The laminate may be used as an outer layer on absorbent products such as nappies, panty nappies, incontinence shields, sanitary towels or bandages.

Abstract: Fibrous material layer intended to be incorporated in an absorbent article. The layer ( 5 ) comprises at least two webs of tow fibers arranged on top of each other, which are bonded to each other into a laminate by means of a bonding pattern, and where one is corrugated and the other web is substantially smooth, wherein the corrugated web exhibits a more open structure in comparison to the smooth web. A method of manufacturing the layer ( 5 ) in question, in which method at least two separate webs ( 15 a, b) of opened and into a layer spread-out tow are fed into a bonding station ( 20 ), which webs exhibit different web tensions and/or web speeds, and that the webs ( 15 a, b) with maintained relative difference in web tension and/or web speed are bonded together in said bonding pattern ( 10 ) into a laminate.

Abstract: A backsheet for an absorbent article includes an inner liquid-impermeable film layer (1′) and an outer layer (3′) of nonwoven. The inner liquid-impermeable film layer includes at least one printed area (2). The outer layer of nonwoven (3′) is provided with printing (4) in all areas except in an area or areas (5) covering the at least one printed area (2) of the inner liquid-impermeable film layer. The basis weight of the outer nonwoven layer is less than 20 g/m2.
