Abstract

Procédé de fabrication d'une feuille hydrolysable qui peut être utilisée comme chiffon mouillé, et possède une résistance au mouillé et une dispersibilité dans l'eau accrues. Le procédé comprend les étapes suivantes: on constitue une feuille hydrolysable à partir d'un mélange d'une carboxyméthylcellulose gonflant légèrement dans l'eau ou insoluble dans l'eau, ayant un degré de substitution compris entre 0,30 et 0,60, et un pH d'au moins 5,0, et/ou de ses sels, avec des fibres dispersibles dans l'eau; puis on ajoute du chlore au mélange avant ou après l'étape de fabrication de la feuille.
