Abstract

La présente invention concerne une couche jetable (1) qui comprend des rabats abdominaux (FA) au niveau de la taille et des rabats arrière (FB) au niveau de la taille disposés à l'extérieur des extrémités avant et arrière (23A, 23B) dans la direction longitudinale (X) d'un absorbant (23) et s'étendant dans la direction transversale (Y). Les rabats arrière (FB) au niveau de la taille comprennent une feuille hydrophobe (4) du côté de la peau et une feuille hydrophile (5) qui n'est pas du côté de la peau. La feuille (4) du côté de la peau comporte des évidements (41) qui forment des creux vers la feuille (5) qui n'est pas du côté de la peau et des zones thermofixées (42) sur les sommets à l'intérieur des évidements (41). Les zones thermofixées (42) comprennent des parties dans lesquelles les fibres constituant la feuille (4) du côté de la peau ont été fondues et les fibres constituantes sont thermofixées l'une à l'autre sans espaces. La masse surfacique de la feuille (4) du côté de la peau est inférieure ou égale à 30 g/m2. L'épaisseur des zones thermofixées (42) représente une valeur inférieure ou égale à 1/3 de l'épaisseur des parties de la feuille (4) du côté de la peau, sans compter les évidements (41).
