Abstract

Procédé de fabrication de structures absorbantes, consistant à associer des particules d'un produit absorbant les liquides à un support, et à déposer un liant sur le composite obtenu. Le dépôt de liant est effectué soit par pulvérisation, soit par transfert. Le support peut être un film thermoplastique, un matériau fibreux, du genre matelas de fibres cellulosiques ou de feuilles de tissus-ouate. Application à la fabrication d'articles d'hygiène, de produits d'essuyage ou de produits utilisables en agriculture.
