A method of making sanitary products giving a high wearing comfort is disclosed. The method comprises steps of forming three superposed interconnected layers (14, 15, 16). The outer layers (14, 16) are made of hydrophobic fibers and the intermediate layer (15) is made of hydrophilic fibers. The top sheet of the sanitary product is constituted by the layer (16). In this outer layer flow lines are made by means of an embossing roller (21) having a pattern of raised ridges. The ridges are provided with a penetrant which then is applied to the front sheet (16) thereby neutralizing the hydrophobicity of the fibers and thereby providing a pattern of flow lines being hydrophilic and allowing a body liquid to flow through the front sheet (16).
L'invention concerne un procédé de fabrication d'articles d'hygiène procurant un degré de confort élevé. Ledit procédé consiste à former trois couches superposées (14,15,16) reliées entre elles. Les couches externes (14,16) sont constituées de fibres hydrophobes et la couche intermédiaire (15) de fibres hydrophiles. La couche (16) constitue la feuille supérieure de l'article d'hygiène. Des lignes d'écoulement sont formées dans cette couche externe au moyen d'un rouleau de gaufrage (21) présentant un motif de stries dotées d'un agent pénétrant qui est ensuite appliqué sur la feuille supérieure (16) afin de neutraliser les propriétés hydrophobes des fibres et produire un motif de lignes d'écoulement hydrophiles permettant au liquide biologique de traverser la feuille supérieure (16).
