des Indigos.of the indigo.
Patentiert im Deutschen Reiche vom 14. Mai 1912 ab. Längste Dauer: 20. Dezember 1926.Patented in the German Empire on May 14, 1912. Longest duration: December 20, 1926.
Magnesiumleukoverbindungen des Indigos sind bereits vor langer Zeit durch doppelte Umsetzung des Indigweißalkalis mit Magnesiumsalzen dargestellt worden (vgl. »Der IndigOK von Georgievics 1892, S. 147). Nähere Untersuchungen haben ergeben, daß, analog der im Patentanspruch des Patents 270520 geschützten Methode — Reduktion der Küpenfarbstoffe mittels Hydrosulfit unter direktem Zusatz von Magnesiumhydroxyd —■-, Indigo sich in eine zum direkten Färben außerordentlich geeignete Leukoform überführen läßt, wenn man den Farbstoff mit Magnesiumhydroxyd auf Zusatz von Natriumhydrosulfit anrührt. Dieses technisch sehr wichtige Ergebnis ist durchaus überraschend. Erstens war es nicht vorauszusehen, daß sich auf diese Weise (also nicht durch die bereits bekannte doppelte Umsetzung) überhaupt eine Magnesiumleukoverbindung des Indigos bildet, zweitens lag die Befürchtung nahe, daß beim längeren Lagern der Leukoverbindung in Gegenwart von überschüssigem Natriumhydrosulfit eine beim Färben schädliche Überreduktion oder gar größere Indigoverluste entstehen könnten.Magnesium leuco compounds of indigo have been produced a long time ago by the double conversion of indigo white alkali with magnesium salts (cf. »Der IndigOK by Georgievics 1892, p. 147). More detailed studies have shown that, analogous to the method protected in the patent claim of the patent 270520 - reduction of the vat dyes by means of hydrosulfite with direct addition of magnesium hydroxide - ■ -, indigo can be converted into a leuco form which is extremely suitable for direct dyeing if the dye is mixed with magnesium hydroxide stirred on the addition of sodium hydrosulfite. This technically very important result is quite surprising. Firstly, it could not be foreseen that in this way (i.e. not through the already known double conversion) a magnesium leuco compound of indigo would be formed at all; secondly, there was the fear that if the leuco compound was stored for a longer period in the presence of excess sodium hydrosulfite, an over-reduction would be harmful to dyeing or even greater indigo losses could arise.
Die Darstellung der zum Färben direkt geeigneten Produkte geschieht entweder trocken oder in Pastenform.The products that are directly suitable for dyeing are presented either dry or in paste form.
Beispiel ι.Example ι.
ίο kg Indigo trocken, ίο kg lufttrockenes, lockeres Magnesiumhydroxyd und io kg Natriumhydrosulfit werden längere Zeit in der Kugelmühle zusammen verrieben.ίο kg dry indigo, ίο kg air dry, loose magnesium hydroxide and 10 kg of sodium hydrosulphite are used for a long time Ball mill rubbed together.
10 kg Indigo, 85 kg ioprozentige Magnesiumhydroxydpaste und 15 kg Natriumhydrosulfit werden in der Kugelmühle verrieben, dann wird die ioprozentige grünliche Paste abgefüllt. 10 kg indigo, 85 kg io percent magnesium hydroxide paste and 15 kg of sodium hydrosulfite are ground in the ball mill, then the 10% greenish paste is bottled.
Die Mengenverhältnisse von Magnesiumhydroxyd, Hydrosulfit und Wasser können in weiten Grenzen abgeändert werden.The proportions of magnesium hydroxide, hydrosulfite and water can be in wide limits.
Das Färben mit diesen Leukoverbindungen gestaltet sich nun sehr einfach. Im allgemeinen erzielt man aus langen Flotten schwächere, aus kurzen Flotten stärkere Färbungen. Außer der Länge der Flotten ist auch die Temperatur beim Färben von Einfluß. Baumwolle zieht besser aus kalten, Wolle aus warmen Bädern. Seide zieht am besten lauwarm. Man hat es infolgedessen an der Hand, bei gemischten Textilfasern beliebige Effekte zu erzielen, indem entweder alle Fasern gleichmäßig (lauwarm) oder nur eine Faser vorzugsweise angefärbt werdenStaining with these leuco compounds is now very easy. In general weaker dyeings are obtained from long liquors and stronger dyeings from short liquors. In addition to the length of the liquor, the temperature also has an influence on dyeing. Cotton pulls better out of cold, Wool from warm baths. Silk is best lukewarm. You have it as a result on hand to achieve any desired effects with mixed textile fibers by either all fibers are dyed evenly (lukewarm) or only one fiber is preferably dyed
kann. Da die Überreduktion von Indigo nicht eintritt, sind Verluste an Farbstoff ausgeschlossen und das Verstärken der Küpen bietet keine Schwierigkeiten. Ein weiterer Vorzug der Magnesiumküpen von Indigo ist, daß man die Tiefe der Nuance bei sehr gutem Egalisieren und ausgezeichneter Echtheit in einem bis jetzt ungeahnten Maße steigern kann. Auf Wolle lassen sich auf diese ίο Weise z. B. in einem einzigen Zuge fast schwarze Färbungen erzielen. Trotz der Tiefe sind die auf diese Weise hergestellten Indigofärbungen ausgezeichnet reib- und waschecht. Für die tierische Faser ist der Umstand, daß die Magnesiumküpe schwachsauer reagiert, ebenfalls von allergrößter Bedeutung.can. Since the overreduction of indigo does not occur, losses of dye are excluded and strengthening the vats presents no difficulty. Another advantage of Indigo's magnesium vats is that you get the depth of the nuance with very good leveling and excellent authenticity can increase to an unprecedented degree. On wool can be used on this ίο way z. B. in a single train almost achieve black colors. Despite the depth, the dyes made in this way are indigo excellent rub and wash fastness. For animal fiber, the fact that the magnesium vat reacts weakly acidic, also of the utmost importance.
