Abstract

L'invention concerne la production d'une structure fibrillaire d'ester cellulosique qui soit à la fois aérée et opaque pour qu'elle puisse être utilisée dans des filtres d'ester celluloPour y parvenir, on fait passer une enduction d'ester cellulosique dans un mélange d'un solvant et d'un non-solvant de cet ester qui sont miscibles entre eux à travers un venturi, dans lequel on introduit un liquide de coagulation et on recueille un precipité d'ester cellulosique ayant la structure souhaitée. Application d'une telle structure à la fabrication de filtres pour cigarettes.The invention relates to the production of a cellulosic ester fibrillar structure which is both aerated and opaque for use in cellulosic ester filters. To achieve this, a coating of cellulosic ester is passed through it. a mixture of a solvent and a non-solvent of this ester which are miscible with one another through a venturi, into which a coagulation liquid is introduced and a cellulose ester precipitate having the desired structure is collected. Application of such a structure to the manufacture of filters for cigarettes.
