Abstract

La présente invention concerne un article de traitement de liquides corporels dont la torsion en utilisation peut être inhibée, et un procédé de production associé. Le protège-slip (1) comprend : des feuillets de surface interne et externe (2, 3) ; une entre-doublure absorbant les liquides (4) située entre les feuillets de surface interne et externe (2, 3) ; et un feuillet étanche (5) avec lequel le feuillet de surface externe (3) est recouvert. Un non-tissé fibré contenant une résine synthétique thermoplastique est utilisé comme feuillets de surface interne et externe (2, 3), et de la pâte défibrée est utilisée comme entre-doublure (4). Sur le feuillet de surface interne (2) est formée une pluralité de rainures comprimées (7) vers le feuillet de surface externe (3) de façon à ce que les rainures comprimées (7) forment un motif de grillage en se prolongeant jusqu'à se croiser les unes avec les autres dans le sens de la longueur (Y) et dans le sens de la largeur (X). Les rainures comprimées (7) comprennent une première partie formée à partir du feuillet de surface interne (2) vers l'entre-doublure (4) et des deuxièmes parties chacune dotée d'un fond et formée à partir de la partie inférieure de la première partie vers le feuillet de surface externe (3) de façon à ce l'intervalle entre les deux bords latéraux soit progressivement réduit. Au niveau des fonds des deuxièmes parties, au moins des parties des fibres formant le feuillet de surface interne (2) et les fibres formant le feuillet de surface externe (3) sont en contact les unes avec les autres et soudées.
