NIELS GEORG SÖRENSEN in STOCKHOLM. Verfahren zum Schwarzfärben von Leder unter Anwendung von Vanadin-Verbindungen.NIELS GEORG SÖRENSEN in STOCKHOLM. Process for dyeing leather black using vanadium compounds.
Patentirt im Deutschen Reiche vom 13. October r88o ab.Patented in the German Empire from October 13th, 1880.
Durch dieses Verfahren wird das Schwarzfärben des Leders leichter, reinlicher, gründlicher und dauerhafter ausgeführt, als solches bei den jetzt gebräuchlichen Verfahren der Fall ist.This process makes the blackening of the leather easier, cleaner and more thorough and carried out more permanently than such in the now common methods of the Case is.
Das Leder, bei welchem dieses neue Verfahren angewendet werden kann, ist solches, welches durch Rothgerberei erhalten wurde, oder in anderen Worten, welches mittelst Gerbsäure oder Gallussäure präparirt ist und diese Säuren oder deren Derivate oder Verbindungen enthält, welche bei Behandlung mit Vanadin-Verbindungen sich schwarz färben; dieDerivate oder Verbindungen besagter Säuren, auf welche die Vanadin-Verbindungen den gewünschten Effect haben, sowie die Art der Vanadin-Verbindungen, welche sich zu diesem Zweck eignen, sind den Chemikern bekannt.The leather to which this new process can be applied is one which was obtained by red tannery, or in other words, which by tannic acid or gallic acid is prepared and contains these acids or their derivatives or compounds, which turn black on treatment with vanadium compounds; the derivatives or compounds Said acids on which the vanadium compounds have the desired effect have, as well as the type of vanadium compounds which are suitable for this purpose, are the Known to chemists.
Das Schwarzfärben des Leders kann zu irgend welcher Zeit, nachdem solches, wie oben erwähnt, gegerbt ist, stattfinden; die Wirkung der Vanadin-Verbindung, welche in gelöstem Zustande gebraucht wird, auf die Oberfläche und den inneren Körper des damit behandelten Leders ist ein Schwarzfärben derselben; das Wort »schwarz« wird hier nur in seiner gewöhnlich angenommenen Bedeutung und nicht in ganz absolutem Sinn gebraucht.The leather can be dyed black at any time after the above mentioned is tanned, take place; the action of the vanadium compound, which in the dissolved state is used, on the surface and the inner body of the leather treated therewith is a black dyeing thereof; the The word "black" is used here only in its usually assumed meaning and not used in the absolute absolute sense.
Um der Qualität des behandelten Leders in keiner Weise Eintrag zu thun, ist es vortheilhaft, eine neutrale Vanadin-Lösung zu gebrauchen, und habe ich eine solche in der einprocentigen neutralen Lösung von vanadinsaurem Ammoniak als sehr zweckentsprechend gefunden.In order not to impair the quality of the treated leather in any way, it is advantageous to to use a neutral vanadium solution, and I have one in the one percent neutral solution of ammonia vanadium was found to be very appropriate.
Zur Erlangung einer vollen schwarzen Farbe ist der Gebrauch mäfsiger Wärme bei dem Färben am entsprechendsten.In order to obtain a full black color, the use of moderate heat is essential Color most appropriately.
Ein grofser Vortheil der. neuen Methode besteht in der Behandlung fertiger Lederwaaren, wie z. B. Schuhe und Stiefel, da das Risiko, die nicht zu färbenden Theile derselben zu beschädigen, vermieden ist, und bei Sattlerwaaren z. B. das Leder sich schwarz färbt, während die Nähte ihre natürliche Farbe behalten; das Schwarzfärben findet dabei statt, ohne dafs der Arbeiter seine Hände beschmutzt. Ein weiterer Vortheil der neuen Methode ist, dafs die Färbung das Leder tiefer durchdringt und haltbarer ist, als bei der jetzt angewendeten Färbemanier.A great advantage of. new method consists in the treatment of finished leather goods, such as B. Shoes and boots, since the risk of damaging the parts not to be dyed is avoided, and for saddlery z. B. the leather turns black while the seams retain their natural color; the blackening takes place without the Worker soiled his hands. Another advantage of the new method is that staining the leather penetrates more deeply and is more durable than with the dyeing method now used.
