Description

Verfahren zur Herstellung von plastischen Massen aus Abfall-Filtertüchern der Acetylcellulosekunstseidenfabriken Für Abfall-Filtertücher der Acetylcellulosekunstseidenfabriken war eine entsprechende Verwertung unmöglich; sie wurden bisher verbrannt. So gingen hochwertige Stoffe der Wirtschaft verloren, denn diese Abfälle enthalten noch ungefähr q.30/0 Celluloseacetat. Verfahrensgemäß werden die bei der Acetatkunstseidenherstellung anfallenden Abfall-Filtertücher zu Flocken gemahlen, die neben Celluloseacetat noch hochwertige Baumwolle aufweisen, aus welcher solche Filtertücher hergestellt sind.Process for the production of plastic masses from waste filter cloths of the acetyl cellulose artificial silk factories For waste filter cloths of the acetyl cellulose artificial silk factories a corresponding recovery was impossible; so far they have been burned. So went high-quality substances lost to the economy, because this waste still contains approximately q.30 / 0 cellulose acetate. According to the method used in the manufacture of acetate rayon Accruing waste filter cloths ground into flakes, which in addition to cellulose acetate still have high quality cotton from which such filter cloths are made.

Dieses gemahlene Produkt -kommt in eine Knetmaschine unter Zugabe von niedrigsiedenden, zum Auflösen des Celluloseacetats geeigneten Lösungsmitteln sowie dem Verwendungszweck angepaßten Weichmaohungsmitteln. Die Masse wird in der Maschine etwa 1/z Stunde verknetet. Die in den gemahlenen, flockigen Filtertuchabfällen enthaltene Acetylcellulose wird durch die Lösungsmittel gelöst und mittels des Knetprozesses mit den Baumwollfasern zu einer homogenen Masse umgewandelt. Die dabei entstehende plastische Masse stellt ein äußerst zähes, widerstandsfähiges Produkt dar. Die Masse kann in Büchsen, Tuben od. dgl. verkauft werden. Der Verwendungszweck ist ein vielseitiger, z. B. für jede Art von Besohlung von Schuhwerk. Die Auswalzung auf Gewebeuntergrund jeglicher Art sowie Filz u. dgl. ergibt einen Fußboden- und Treppenbelag. In Plattenform ist deren Verwendung ebenfalls vielseitig, z. B. für Besohlzwecke, Aktentaschen, Koffer, Riemen und vieles andere. Die Masse selbst und sämtliche daraus hergestellten Artikel sind rooo/o öl- und benzinfest, wasserfest, säurebeständig und hochisolierend gegen elektrische Ströme.This ground product is added to a kneading machine of low-boiling solvents suitable for dissolving the cellulose acetate as well as softeners adapted to the intended use. The crowd is in the Machine kneaded for about 1/2 hour. The ones in the ground, flaky filter cloth waste The acetyl cellulose contained in it is dissolved by the solvents and by means of the kneading process converted into a homogeneous mass with the cotton fibers. The resulting plastic mass is an extremely tough, resistant product. The mass can be sold in cans, tubes or the like. The purpose is versatile, z. B. for every type of soling of footwear. The rolling out on the fabric substrate of any kind, as well as felt and the like, result in a floor and stair covering. In plate form their use is also versatile, e.g. B. for soling purposes, briefcases, Suitcases, straps and much more. The crowd itself and everyone Articles made from it are rooo / o oil and petrol resistant, waterproof and acid resistant and highly insulating against electrical currents.
