Description
Verfahren zur Herstellung von Lederfaserwerkstoffen Es ist bereits vorgeschlagen, Lederfaserwerkstoffe ,aus Leder-, Textil- oder Papierabfällen und Emulsionen von Bindemitteln, wie z. iBV. Polyvinyl-oder Polyacrylharzen, unter Verwendung von Aluminiumsulfat oder Chromsulfat als Fällüngsmittel herzustellen.Process for the production of leather fiber materials It is already proposed leather fiber materials, from leather, textile or paper waste and Emulsions of binders, such as. iBV. Polyvinyl or polyacrylic resins, using to produce aluminum sulfate or chromium sulfate as a precipitant.
Es wurde nun gefunden, daB man an iStelle von Aluminium- oder Chromsulfat mit Vorteil die Salze des Aluminiums oder des Chroms mit aliphatischen Säuren verwenden kann.It has now been found that instead of aluminum or chromium sulfate one can use it Use with advantage the salts of aluminum or chromium with aliphatic acids can.
Als aliphatische Säuren kommen vor allem flüchtige aliphatische Säuren, insbesondere Ameisensäure oder Essigsäure, in Betracht.The main aliphatic acids are volatile aliphatic acids, especially formic acid or acetic acid.
Die Herstellung von Lederfaserwerkstoffen gemäß der vorliegenden Erfindung kann dabei in etwa folgender Weise -durchgeführt werden: Lederabfälle werden in bekannter Weise zu Lederfasern zerkleinert und in einen Holländer oder in einen Mischbottich mit so viel Wasser eingetragen, daB der Gehalt an trockener Lederfaser etwa 3 % beträgt. Nachdem der Lederfaserbrei durch Zusatz von Alkalilauge schwach alkalisch gestellt ist, um eine vorzeitige Ausfällung der zur Verwendung gelangenden Bindemittel zu verhüten, werden die Bindemittel in einer Menge von ao bis 5o%, berechnet auf den Gehalt an trockener Lederfaser, zugesetzt; als Bindemittel eignen sich Emulsionen von Polyvinyl- und Polyacrylharzen. Der Faserbrei wird nun i Stunde lang intensiv bewegt, um eine innige Verbindung der Lederfasern mit dem Bindemittel herzustellen. Hierauf wird Aluminiumtriformiat in Form einer 5 bis ioo/oigen Lösung dem ständig weiterbewegten Faserbrei allmählich zugegeben, und zwar so lange, bis das vorhandene Bindemittel restlos ausgefällt ist. Dies erkennt man daran, daß eine Probe der Flotte klar durch ein Filter läuft.The manufacture of leather fiber materials according to the present invention can be carried out in the following way: Leather waste is in As is known, comminuted to leather fibers and placed in a Dutchman or in a Mixing tub with so much water added that the content of dry leather fiber is about 3%. After the leather pulp becomes weak by adding alkali is made alkaline to prevent premature precipitation of the used To prevent binders, the binders are calculated in an amount of ao to 5o% on the content of dry leather fiber, added; emulsions are suitable as binders of polyvinyl and polyacrylic resins. The pulp will now be intense for an hour moved to create an intimate connection between the leather fibers and the binder. Aluminum triformate is then used in the form of a 5 to 100% solution to the continuously moving pulp gradually added until the existing binder has completely precipitated. This can be recognized by the fact that a Sample of the liquor runs clear through a filter.
Anschließend wird der Faserbrei auf einer Papiermaschine oder in iSiebkästen entwässert. Die gebildeten feuchten Platten werden je nach dem gewünschten Endprodukt mehr oder weniger stark gepreßt und bei etwa 5o° getrocknet. Nach der Trocknung kann gewünschtenfalls eine Zurichtung erfolgen, z. B. durch Aufprägen eines Narbenmusters, durch Besprühen mit Deckfarbe oder durch Bügeln bzw. Kalandern.The pulp is then processed on a paper machine or in sieve boxes drains. The formed wet plates are depending on the desired end product pressed more or less strongly and dried at about 50 °. After drying if desired, a dressing can be carried out, e.g. B. by embossing a grain pattern, by spraying with top paint or by ironing or calendering.
Falls weiche Lederwerkstoffe hergestellt werden sollen, sind je nach dem gewünschten Weichheitsgrad 5 bis zoo/o an Weichmachern, berechnet auf die angewandte Menge an Bindemitteln, dem Bindemittel vor denn Einbringen in den Lederfaserbrei zuzusetzen; als recht zweckmäßig haben sich dabei Gemische von verschiedenen Weichmachern, wie z. B. solche aus Polyglykoläthern und Trikresylphosphat, erwiesen.If soft leather materials are to be produced, depending on the desired degree of softness 5 to zoo / o of plasticizers, calculated on the applied Amount of binders, the binder before being introduced into the leather pulp to add; Mixtures of different plasticizers, such as B. those made from polyglycol ethers and tricresyl phosphate have been proven.
Die erfindungsgemäß erhaltenen Lederfaserstoffe zeichnen sich dadurch aus, daß die Reißfestigkeit auch bei längerer Lagerung keine wesentliche Abnahme erfährt und daß beim 1NTähen der Lederfaserstoffe keine Carbonisierung der Nähfäden eintritt, wie dies beider Verwendung vonAluminium-oder Chromsulfat häufig zu beobachten ist.The leather fibers obtained according to the invention are distinguished by this from the fact that the tear strength does not decrease significantly even after prolonged storage and that when the leather fibers are sewn, the sewing threads are not carbonized occurs, as is often observed with the use of aluminum or chromium sulphate is.
