Abstract

La présente invention concerne un papier absorbant ayant une souplesse et une douceur supérieures ou égales à celles des papiers absorbants humidifiés conventionnels, tout en étant moins collant lors de l'utilisation. L'invention a également pour objet un papier absorbant qui ne peut pas être facilement déchiré après que le papier a absorbé de l'eau. Un papier absorbant à deux feuilles présente des surfaces sur lesquelles est appliquée une solution chimique de sorte que la quantité de produits chimiques contenus dans les deux surfaces vaut de 1,4 à 4,5 g/m2 et de sorte que la quantité de produits chimiques contenus dans l'une des deux feuilles qui constituent le papier à deux feuilles vaut de 0,67 à 1,5 fois la quantité de produits chimiques contenus dans l'autre feuille. La teneur en constituants huileux dans les produits chimiques est inférieure à 7,0 pourcents en masse, et la teneur en silicones est inférieure à 0,1 pourcent en masse.
