Abstract

L'invention concerne un procédé de préparation d'une feuille filtrante fibreuse en ester cellulosique non tissée. Ce procédé consiste à préparer une feuille dans laquelle 5 à 35 % de l'ester cellulosique se présente sous la forme de corps fibrillaires ayant une structure aérée. On y parvient en mélangeant et en essorant une pâte aqueuse de fibres discontinues et de corps fibrillaires dans les proportions indiquées. Ces feuilles sont utilisées comme filtres, notamment pour la fumée de tabac.Disclosed is a process for preparing a nonwoven cellulose ester fibrous filter sheet. This process involves preparing a sheet in which 5 to 35% of the cellulose ester is in the form of fibrillar bodies having an aerated structure. This is achieved by mixing and squeezing an aqueous pulp of staple fibers and fibrillar bodies in the proportions indicated. These leaves are used as filters, especially for tobacco smoke.
