Abstract

L'invention concerne un succédané du tabac. La substance à fumer de l'invention est obtenue à partir de viscose de cellulose régénérée contenant TiO2 et du charbon actif. D'un bain de filage 1, on tire une mèche 2 de fibres ondulées. En 3, celle-ci est découpée en brins qui sont cardés en 5. Le ruban 6 ainsi formé passe dans un bain 8 d'agent modificateur de combustion et dans un séchoir à air 10, puis traverse un four de pyrolyse Il à profil de température. Le toron pyrolysé passe dans d'autres bains 12 et 16 et d'autres séchoirs 14 et 18 pour recevoir d'autres agents (producteur de fumée, stimulant nicotiné, aromatisant) pour être transformé en cigarettes à bout filtre 23 par machines classiques 20 et 22. La substance à fumer ne dégage aucun produit de combustion toxique et, par sa durete et sa chute de pression, se rapproche des cigarettes ordinaires.The invention relates to a tobacco substitute. The smoking substance of the invention is obtained from regenerated cellulose viscose containing TiO2 and activated carbon. From a spinning bath 1, a strand 2 of corrugated fibers is drawn. At 3, the latter is cut into strands which are carded at 5. The strip 6 thus formed passes through a bath 8 of combustion modifying agent and into an air dryer 10, then passes through a pyrolysis oven II with a profile of temperature. The pyrolyzed strand passes through other baths 12 and 16 and other dryers 14 and 18 to receive other agents (smoke producer, nicotine stimulant, flavoring) to be transformed into filter-tipped cigarettes 23 by conventional machines 20 and 22. The smoking material does not emit any toxic combustion products and, in its hardness and pressure drop, is similar to regular cigarettes.
