Es ist bekannt, Fasermatten bis zu einem spezifischen Gewicht von 0,01 durch Behandeln von Acetatfasern mit Weichmachern und anschließendes Krempeln und Trocknen in einem Wärmekanal unter Ausnutzung des Klebrigwerdens der Acetatfasern ohne zusätzliche Bindemittel herzustellen.It is known to produce fiber mats up to a specific gravity of 0.01 by treating Acetate fibers with plasticizers and then carding and drying in a heating tunnel Take advantage of the tackiness of the acetate fibers without additional binders.
Wegen des niederen spezifischen Gewichtes sind solche Fasermatten leicht brennbar und daher als Luftfilter wenig geeignet.Because of the low specific weight, such fiber mats are easily combustible and therefore as Air filter not very suitable.
Es ist ferner bekannt, chlorhaltige Weichmacher, z. B. Trichloräthylphosphat, zu verwenden. Man erhält so zwar schwer bzw. nicht brennbare Fasermatten, jedoch ist die Herstellung mit großen technischen Schwierigkeiten verbunden, da diese Weichmacher bereits in der Kälte zu einer Faseranlösung führen und so ein kontinuierliches Krempeln unmöglich machen. Außerdem muß der größte Teil des Weichmachers in den Fasern erhalten bleiben, was wiederum zu einer starken Erniedrigung des Schmelzpunktes der Fasern führt, so daß solche Matten zwar nicht bzw. schwer brennen, jedoch in Kontakt mit Feuer schmelzen und dadurch Verbrennungen hervorrufen können.It is also known to use chlorine-containing plasticizers, e.g. B. trichloroethyl phosphate to use. You get so although difficult or non-flammable fiber mats, however, the production with large technical Difficulties are associated, as these plasticizers already dissolve fibers in the cold and thus make continuous carding impossible. Besides, most of it must of the plasticizer are retained in the fibers, which in turn leads to a strong reduction in the Melting point of the fibers leads, so that such mats do not burn or burn hard, but in Contact with fire can melt and cause burns.
Man kann nichtbrennbare Fasermatten auch durch Verwendung von nichtbrennbaren plastifizierbaren Fasern, z. B. aus Polyvinylchlorid usw., herstellen. Bei der Überführung der Fasern in klebrigen Zustand tritt wegen der hohen Temperatur gleichzeitig ein Schrumpfen der Fasern ein, so daß es nicht möglich ist, formgetreue Produkte zu erhalten.Non-combustible fiber mats can also be made by using non-combustible plasticizable ones Fibers, e.g. B. made of polyvinyl chloride, etc., produce. When the fibers become sticky At the same time, the fibers shrink because of the high temperature, so that it is not possible is to get dimensionally accurate products.
Eine Beimischung solcher nichtbrennbaren Fasern zu Acetatfasern bis zur Erhaltung der Formtreue ist jedoch nur in einer Menge möglich, die zu gering ist, um eine nichtbrennbare Fasermatte zu erhalten.An admixture of such non-flammable fibers with acetate fibers is necessary until the shape is retained but only possible in an amount that is too small to obtain a non-combustible fiber mat.
Nun ist gefunden worden, daß man nichtbrennbare formtreue Fasermatten erhält, wenn man ein Fasergemisch ausIt has now been found that one obtains non-combustible dimensionally stable fiber mats when one Fiber mixture

ao barten Teilen der Faser eintritt. Man kann den Weichmacher auch vollständig wegdampfen, ohne dadurch die Nichtbrennbarkeit zu beeinträchtigen. In diesem Falle findet auch keine Schmelzpunkterniedrigung der Fasern statt, die bei der Berührung mit offener Flamme zu dem lästigen Abtropfen führt.ao exposed parts of the fiber enters. You can also completely evaporate the plasticizer without thereby impairing the non-combustibility. In this case there is also no lowering of the melting point the fibers instead, which leads to the annoying dripping when touching an open flame.
Zur Erniedrigung der Viskosität des Sb2O3-haltigen Weichmachers kann ein Lösungsmittel zugesetzt werden.A solvent can be added to lower the viscosity of the Sb 2 O 3 -containing plasticizer.
Ein Faservlies, bestehend aus 80 % Diacetatfasern, 3 den, und 20% Polyvinylchloridfasern, 3 den, wird mit 70 Teilen Benzolsulfosäure-butyl-amid und 30 Teilen Antimontrioxyd so imprägniert, daß auf das Fasergemisch 10 % dieser Mischung aufgebracht werden.A fiber fleece, consisting of 80% diacetate fibers, 3 den, and 20% polyvinyl chloride fibers, 3 den, is with 70 parts of benzenesulfonic acid butyl amide and 30 parts of antimony trioxide so impregnated that 10% of this mixture is applied to the fiber mixture will.
Die so imprägnierten Fasern sind lagerstabil. Sie werden zu einem Vlies von 300 g/m2 gekrempelt und in einem Wärmekanal bei 120° C verfestigt. Es wird eine nichtbrennbare Matte mit einem spezifischen Gewicht von 0,015 erhalten.The fibers impregnated in this way are stable on storage. They are carded to a fleece of 300 g / m 2 and solidified in a heat tunnel at 120 ° C. A non-combustible mat with a specific weight of 0.015 is obtained.
Ein Faservlies, bestehend aus 75 Teilen Diacetatfasern, 28 den, und 25 Teilen einer Mischpolymerisatfaser, 5 den, bestehend aus 60% Vinylchlorid und 40% Acrylnitril, werden mit dem im Beispiel 1 genannten Weichmacher und Antimontrioxyd imprägniert, zu einem Vlies von 200 g/m2 verlegt und anschließend wie im Beispiel 1 verfestigt. Es wird eine sehr lockere, sehr poröse Fasermatte mit einem spezifischen Gewicht von 0,012 erhalten.A fiber fleece, consisting of 75 parts of diacetate fibers, 28 den, and 25 parts of a mixed polymer fiber, 5 den, consisting of 60% vinyl chloride and 40% acrylonitrile, are impregnated with the plasticizer and antimony trioxide mentioned in Example 1, to form a fleece of 200 g / m 2 laid and then solidified as in Example 1. A very loose, very porous fiber mat with a specific weight of 0.012 is obtained.
