A method for producing an absorbent structure in an absorbent article, such as a wound dressing and like article, which is produced by using absorption material in reel form directly in the product, without first defibering the absorbent material, and thereafter forming a mat. The material has good wicking and swelling properties which are well adapted to the function of the product, a high degree of surface dryness is obtained among other things. In addition to cellulose fibres, the absorbent structure may also include superabsorbent material and/or binding fibres among other things. The pulp mat is very thin, therewith obviating the need to further compress the product. With regard to certain product applications, the material is softened mechanically prior to its use as absorption material.
Procédé de production d'une structure absorbante dans un article absorbant, tel qu'un pansement ou un article similaire, que l'on produit en utilisant un matériau d'absorption se présentant en bobine directement dans le produit, sans défibrage dudit matériau absorbant, et en formant ensuite un matelas. Ledit matériau possède de bonnes propriétés d'imbibition et de gonflement qui sont bien adaptées à la fonction du produit. Entre autres, ledit produit présente un degré élevé de siccité de surface. En plus des fibres de cellulose, la structure absorbante peut également inclure un matériau superabsorbant et/ou des fibres de liaison. Le matelas de pulpe est très mince, ce qui élimine le besoin de comprimer le produit. Pour certaines applications du produit, le matériau est assoupli mécaniquement avant d'être utilisé comme matériau d'absorption.
