Abstract
Procédé de préparation d'une feuille filtrante fibreuse en ester cellulosique non tissée. Il consite à introduire, au moyen d'une aiguille capillaire, de l'acétate de cellulose dissous dans l'acétone dans la gorge d'un venturi qui est alimenté en liquide de coagulation, généralement de l'eau chaude ou froide, de manière à produire des corps fibrillaires qui, associés à des fibres discontinues d'ester cellulosique, permettent d'obtenir des feuilles présentant de bonnes caractéristiques de filtration. Application : filtres pour fumée de tabac.A method of preparing a nonwoven cellulose ester fibrous filter sheet. It consists of introducing, by means of a capillary needle, cellulose acetate dissolved in acetone into the throat of a venturi which is supplied with coagulation liquid, generally hot or cold water, so in producing fibrillar bodies which, combined with staple fibers of cellulose ester, make it possible to obtain sheets having good filtration characteristics. Application: filters for tobacco smoke.
