Abstract

Dans une partie absorbante d'un produit absorbant, des matériaux super-absorbants localisés entre deux feuilles dans une zone absorbante gonflée par absorption de l'humidité d'excréments et des espaces s'étendant dans une direction longitudinale à partir d'une ouverture ménagée au niveau d'une partie de la couche absorbante supérieure orientée vers la région d'entrejambe d'un porteur sont formés entre une zone non absorbante où les matériaux super-absorbants n'existent pas et la couche absorbante supérieure et entre la zone non absorbante et une couche absorbante inférieure. Dans les espaces de produit absorbant, l'humidité des excréments lors d'une deuxième excrétion et d'excrétions suivantes peut se diffuser rapidement sur une vaste zone selon la direction longitudinale de la partie absorbante, et l'humidité des excréments peut être absorbée dans une vaste zone de la partie absorbante. Il en résulte qu'il est possible de maintenir une grande capacité d'absorption lors d'excrétions multiples dans le produit absorbant.
