Abstract

L'invention concerne un article absorbant comprenant au moins une bande double face fibreuse revêtue présentant une couche de stockage sur un côté et une couche d'acquisition sur l'autre côté et/ou une combinaison d'au moins deux bandes double face adhésives revêtues, pour autant qu'une bande comprenne une couche de stockage sur les deux côtés et que l'autre bande comprenne une couche d'acquisition sur les deux côtés, ces couches étant obtenues par : (a) formation d'un mélange renfermant un ou plusieurs monomères formant des polymères superabsorbants, des particules polymères superabsorbantes, de l'eau et un ou plusieurs amorceurs, ledit mélange présentant une viscosité d'au moins 20mPAS (mesurée à 20 °C dans un viscosimètre de Brookfiled ; tige 02, 20 t/m) ; (b) par application dudit mélange sur une bande fibreuse et (c) par exécution de la polymérisation des monomères formant des polymères superabsorbants. L'invention concerne également un article hygiénique jetable renfermant ledit article absorbant.
