Abstract

L'invention concerne une couche-culotte en papier comprenant un nouveau type de couche d'absorption, ainsi qu'un procédé de traitement de cette couche-culotte. Cette couche-culotte en papier comprend une couche de surface (1), une couche d'absorption et une couche inférieure (5), ainsi que des éléments adhésifs de fixation à la taille. 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. Les fils de couture peuvent traverser la couche de surface (1) et relier séparément la couche de surface (1) et la couche inférieure (5) de manière à former un corps d'une seule pièce. 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 (7) peuvent traverser la couche de pâte défibrée (3) et relier séparément la couche de dispersion (2) et la couche de papier absorbant (4). La couche de pâte défibrée (3) peut présenter une pluralité de points de coagulation des fibres. Cette couche-culotte en papier est de structure simple, économique, pratique, fiable, hygiénique et confortable. La couche d'absorption se déforme et rompt difficilement. Le procédé de traitement selon l'invention comprend un procédé de production simple et présente une haute efficacité de production.
