Abstract

Described are methods of manufacturing a cellulose-acetate bundle, the filaments making up the bundle being produced by extruding a solution containing, in addition to cellulose-(2,5)-acetate and solvent, non-toxic compounds which are only slightly soluble in the solution and whose molecular diameter is at least 30 % less than the diameter of the filaments. Water-soluble or bacteriologically degradable organic compounds, in particular starch, starch derivatives or dextrins, are used as the additives.

Description

Zigarettenfilter Cigarette filter
Moderne Zigarettenfilter werden fast ausschließlich aus Zellulose-(2,5)-azetat erzeugt. Gegenüber den früher verwendeten Papier- und Wattefiltern bietet dieses Material den Vorteil, daß das zur Filterherstellung dienende Kabel in einer Vielfalt von Spezifikationen, insbesondere hinsichtlich des Faserquerschnitts, herge¬ stellt werden kann und leicht zu Filtern zu verarbeiten ist, die ihrerseits bei schneilaufenden Zigarettener¬ zeugungsmaschinen verwendet werden können. Die aus Zelluloseazetat hergestellten Filter sehen auch in berauchtem Zustand gut aus. Die dem Kabel (nicht schon den Fasern) bei der Erzeugung der Filterstäbchen zuge- gebenen "Härter" Triazetin (Glyzerintriazetat) bzw. Triäthylenglykoldiazetat verleihen dem Filter hohe Selektivität gegenüber einigen gesundheitlich bedenk¬ lichen Inhaltsstoffen des Tabakrauchs, wie Phenolen und N-Nitrosaminen.Modern cigarette filters are almost exclusively made from cellulose (2.5) acetate. Compared to the paper and cotton filters used previously, this material offers the advantage that the cable used for filter production can be manufactured in a variety of specifications, in particular with regard to the fiber cross section, and is easy to process into filters, which in turn are used for snowing cigarette makers generating machines can be used. The filters made from cellulose acetate also look good when smoked. The "hardener" triazetin (glycerol triacetate) or triethylene glycol diacetate added to the cable (not already the fibers) when producing the filter rods give the filter a high selectivity towards some health-threatening ingredients of tobacco smoke, such as phenols and N-nitrosamines.
Der Nachteil dieses Materials gegenüber chemisch nicht modifizierter Zellulose ist durch seine langsame Abbau- barkeit durch Mikroorganismen gegeben. Nach neueren Forschungsarbeiten wird reines Zellulose-(2,5)-azetat in der Form von Filterstäbchen bei einer Kompostierung unter optimalen Bedingungen in rund 6 bis 9 Monaten durch Mikroorganismen abgebaut, im wässrigen Medium von Kläranlagen ist mit 12 bis 15 Monaten zu rechnen. Erschwert wird dieser Abbau durch die Kompaktheit der Filter, durch die Beigabe der oben erwähnten "Härter" sowie durch ihr adsorbiertes Tabak-Rauchkondensat.The disadvantage of this material compared to chemically unmodified cellulose is its slow degradability by microorganisms. According to recent research, pure cellulose (2.5) acetate in the form of filter sticks is degraded by microorganisms in around 6 to 9 months during composting under optimal conditions; in the aqueous medium of sewage treatment plants, 12 to 15 months can be expected. This degradation is made more difficult by the compactness of the filters, by the addition of the "hardeners" mentioned above and by their adsorbed tobacco smoke condensate.
Man kann davon ausgehen, daß, bedingt durch diese rela¬ tiv langen Abbauzeiten bei der Kompostierung und in Kläranlagen, das Problem "Umweltbelastung durch Ziga¬ rettenfilter" derzeit nicht gelöst ist. Unter möglichst vollständiger Beibehaltung der Vorteile derzeit üblicher Zelluloseazetatfilter sollen diese derart modifiziert werden, daß der mikrobielle Abbau gegenüber dem in der jünsten einschlägigen Literatur angegebenen Zeitbedarf deutlich beschleunigt wird.It can be assumed that, due to these relatively long breakdown times in composting and in sewage treatment plants, the problem of "environmental pollution caused by cigarette filters" has not yet been solved. While maintaining the advantages of currently available cellulose acetate filters as completely as possible, they should be modified in such a way that the microbial degradation is significantly accelerated compared to the time required in the most recent relevant literature.
Die gestellte Aufgabe wird gelöst, wenn Zigaretten¬ filter unter Verwendung von Kabeln hergestellt werden, welche nach den Verfahren gemäß Patentanspruch 1 oder 2 hergestellt worden sind.The object is achieved when cigarette filters are manufactured using cables which have been produced by the method according to claim 1 or 2.
Als erfindungsgemäß einsetzbare wasserlösliche Materia¬ lien kommen Di- und Trisaccharide, Alkali- und Erdalka- lisalze organischer und einiger Mineralsäuren (z.B. Magnesiumchlorid, Magnesiumsulfat, Natriumchlorid, Natriumsulfat, etc.) in Frage.Di- and trisaccharides, alkali and alkaline earth salts of organic and some mineral acids (e.g. magnesium chloride, magnesium sulfate, sodium chloride, sodium sulfate, etc.) are suitable as water-soluble materials which can be used according to the invention.
Unter dem Einfluß von Feuchtigkeit wird das wasser- lösliche Material aus den Zigarettenfiltern heraus¬ gelöst und somit die Struktur der Einzelfasern zer¬ stört. Die sich dabei ergebende große Oberfläche der zurückbleibenden Faserbruchstücke ermöglicht einen schnelleren mikrobiellen Abbau es Zellulose-(2,5)- azetats.Under the influence of moisture, the water-soluble material is removed from the cigarette filters and the structure of the individual fibers is destroyed. The resulting large surface area of the remaining fiber fragments enables a faster microbial breakdown of cellulose (2.5) acetates.
Werden andererseits in der Spinnlösung Stärke, chemi¬ sche oder biologisch partiell abgebaute Stärke, Stärke¬ derivate, stärkehaltige Produkte wie Getreidemehl, Dextrine, suspendiert, so werden diese Zusatzstoffe durch Mikroorganismen des Bodens in Kläranlagen usw. abgebaut. Auch hier wird also die Struktur der Einzel¬ fasern der berauchten Zigarettenfilter zerstört und der weitere mikrobiologische Abbau des zurückbleibenden Zellulose-(2,5)-azetats erleichtert und beschleunigt. If, on the other hand, starch, chemical or biologically partially degraded starch, starch derivatives, starch-containing products such as cereal flour, dextrins are suspended in the spinning solution, these additives are broken down by soil microorganisms in sewage treatment plants, etc. Here too, the structure of the individual fibers of the smoked cigarette filters is destroyed and the further microbiological degradation of the remaining cellulose (2,5) acetate is facilitated and accelerated.
