    Abstract: The present invention relates to a liquid-permeable casing sheet (1) for absorbent sanitary articles, such as sanitary napkins, incontinence guards and diapers. According to the invention, the casing sheet (1) includes a first layer (2) which is corrugated across at least a central part of its surface so as to provide a row of mutually parallel waves having wave crests (3) and wave troughs (4), wherein the wave crests form an article contact surface with the wearer's body when the article is in use. The casing sheet also includes rows of through-penetrating openings (6) which extend perpendicularly to the corrugations or waves and each of which opening passes through a wave crest (3). The invention also relates to a method for producing such a casing sheet. FIG. 1 for publication.

    Abstract: Absorbent article, such as a diaper, pant diaper, incontinence guard, sanitary napkin, wound dressing and the like, comprising a layer of continuous fibres, so-called tow, which have been bonded together in points, lines or spots in a bonding pattern (10), but otherwise are substantially unbonded to each other, wherein the bonding pattern (10) is different in different portions of said layer (5). The layer can either be utilized as a liquid acquisition layer (5) in the article underneath a topsheet (2), as a topsheet (12), or as a combined topsheet and liquid acquisition layer (22).

    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.
