Abstract

L'invention concerne un matelas à langer pourvu d'une couche d'absorption comprenant une couche de surface (1), une couche d'absorption et une couche inférieure (5). La couche d'absorption est située entre la couche de surface (1) et la couche inférieure (5). La couche d'absorption comprend des fils de couture (7) multiples qui s'imbriquent dans celle-ci de manière à diviser la couche d'absorption en structures de voile multiples et à fixer ces structures. La couche d'absorption peut comprendre une couche de pâte défibrée (3), une couche de dispersion (2) au-dessus de celle-ci et une couche de papier absorbant (4) au-dessous de celle-ci, les fils de couture traversant la couche de pâte défibrée (3) uniquement. La couche d'absorption peut également être divisée au moyen d'une pluralité de points de coagulation des fibres placés dans la couche de pâte défibrée (3). L'invention concerne également un procédé de traitement de ce matelas à langer. La couche d'absorption est divisée en structures de voile multiples et fixée, de sorte que l'absorbant à l'intérieur de la couche d'absorption se déforme et rompt difficilement. Le procédé de traitement du matelas à langer selon l'invention est simple et présente une haute efficacité de production.
