Description

ANLAGE IM zur Gebrauchsmusteranmeldung Gm 262 Filter für Tabakrauch Es ist bekannt, zur Entfernung von feinverteilten, festen oder flüssigen Beimengungen aus Tabakrauch faserige Stoffe in Form einer Wirrlage dieser Fasern zu verwenden.ANNEX IM to the utility model registration Gm 262 filter for tobacco smoke It is known to remove finely divided solid or liquid impurities to use fibrous materials from tobacco smoke in the form of a random layer of these fibers.

Gegenstand der Neuerung ist ein Filter zur Entfernung von feinverteilten, festen oder flüssigen Beimischungen aus Tabakrauch, der dadurch gekennzeichnet ist, dass der Filter ganz oder zum Teil aus wirren Fasern aus synthetischen, linearen Hochpolymeren besteht, wobei die Fasern vorwiegend einen Durchmesser zwischen 1 Mikron und 6 Mikron haben.The subject of the innovation is a filter for the removal of finely divided, solid or liquid admixtures from tobacco smoke, which is characterized by that the filter is wholly or partly made of tangled synthetic fibers, linear It consists of high polymers, the fibers predominantly having a diameter between 1 Microns and 6 microns.

Die bisher verwendeten Filter enthalten in der Hauptsache Fasern aus Naturfasern oder auch Fasern auf Kunststoffbasis, die jedoch ausnahmslos wesentlich dicker'sind als die Filter des neuerungsgemässen Filters. In. der nachstehenden Tabelle sind einige für. die Filterherstellung gebräuchlichen Fasern mit dem dazugehörigen Durchmesser angegeben : Faserart : von bis Wolle................ 17 ca. 100 Mikron Zellwolle............. 20 ca. 50 Mikron Celluloseacetat....... 20 ca. 50 Mikron Polyamide............. 18 30 Mikron Polyester............. 15 30 Mikron Der Grad der Filterwirkung hängt in erster Linie von der Grösse der inneren Oberfläche dieser Gebilde ab, die ihrerseits wieder bestimmt wird vom Durchmesser der in dem Filter enthaltenen Faser.The filters used so far mainly contain fibers made from natural fibers or also fibers based on plastic, which, however, without exception are much thicker than the filters of the filter according to the innovation. In. the table below are some for. the filter production of common fibers with the corresponding diameter is indicated: Type of fiber: from to Wool ................ 17 approx. 100 microns Viscose wool ............. 20 approx. 50 microns Cellulose acetate ....... 20 approx. 50 microns Polyamides ............. 18 30 microns Polyester ............. 15 30 microns The degree of filtering effect depends primarily on the The size of the inner surface of these structures, which in turn is determined by the diameter of the fibers contained in the filter.

Wie aus der Tabelle zu entnehmen ist, ist der Durchmesser der bisher für Filterzwecke verwendeten Fasern zwischen 15 Mikron und 100 Mikron. Demgegenüber enthält der neuerungsgemässe Filter Fasern von 1-6 Mikron, vorzugsweise sogar von 2-3 Mikron Durchmesser.As can be seen from the table, the diameter is the same as before fibers used for filtering purposes between 15 microns and 100 microns. In contrast The filter according to the invention contains fibers of 1-6 microns, preferably even of 2-3 microns in diameter.

Die : verwirkung derartiger Filter beträgt ein Vielfaches von derjenigen der bisher gebräuchlichen Filter. Die ideale Wirtlage der verwendeten Mikrofasern für die Herstellung der neuartigen Filter ist ein wesentliches zusätzliches Element für die Verbesserung der Filterwirkung.The effect of such filters is a multiple of that the filters commonly used up to now. The ideal host location for the microfibers used for the production of the novel filter is an essential additional element for improving the filter effect.

Die neuerungsgemässen Filter können in Pfeifen, Zigarren-oder Zigarettenspitzen oder auch in die Mundstücke von Zigaretten eingebaut werden (siehe Abb. 1, 2, 3), wobei eine Filterwirkung in einem bisher noch nicht erreichbaren Ausmass erhalten wird.The filters according to the innovation can be used in pipes, cigar or cigarette holders or can also be built into the mouthpieces of cigarettes (see Fig. 1, 2, 3), with a filter effect obtained in a previously unattainable extent will.

Für besondere Zwecke eignen sich Filter aus einer Mischung von verschiedenen Mikrofasern aus linearen Hochpolymeren. Die neuerungsgemässen Filter können ferner aus Mischungen von bisher verwendetem Fasermaterial z. B. Acetatfasern oder Papierfasern und ferner Fasern (Mikrofasern) aus linearen Hochpolymeren bestehen.Filters made from a mixture of different are suitable for special purposes Microfibers made from linear high polymers. The filters according to the innovation can also from mixtures of previously used fiber material z. B. acetate fibers or paper fibers and further fibers (microfibers) are made of linear high polymers.

Schliesslich hat es sich auch als vorteilhaft erwiesen, die zu reinigenden Gase, wie z. B. Tabakrauch zuerst durch einen Filter aus Mikrofasern und anschliessend durch einen Filter aus normalen bisher verwendeten Fasern oder umgekehrt zu leiten (vgl. Abb 4).Finally, it has also proven to be advantageous to clean the Gases such as B. Tobacco smoke first through a microfiber filter and then to pass through a filter made of normal previously used fibers or vice versa (see Fig. 4).
