Verfahren zur Erzeugung und Befestigung von Indigo auf der Faser.
In den deutschen Patentschriften Nr. 108722 und Nr. 109800 ist ein Verfahren zum Fixieren von Indigo auf der Pflanzenfaser beschrieben, nach welchem es gelingt, auf derselben vermittelst einer aus Indigosalz lkali und einem Verdickungsmittel, z. B. Dextrin

ductionsmittels zu befestigen. Das Verfahren besteht darin, dass man die mit der Druckfarbe bedruckten und getrockneten Gewebe in einem offenen Dämpfkasten-also ohne Druck-unter Ansschluss der Luft und Vermeidung eines Feuchtwerdens der Gewebe dampft.

und der Faser zu löslichem Indigoweiss reduciert ; dieses dringt in die Faser ein und wird dann nach dem Dämpfen beim Waschen und Säuern wieder zu unlöslichem Indigo oxydiert.
Es wurde nun beim weiteren Verfolgen dieses Verfahrens gefunden, dass auf das Ergebnis desselben auch die Temperatur während des Dämpfens einen Einfluss ausübt. Es hat sich nämlich ergeben, dass zur vollen Entfaltung der Indigodrucke, welche mit Indigodruckfarben von verschiedenem Gehalt an Indigo hergestellt sind, auch eine verschiedene Dämpftemperatur erforderlich ist, derart, dass mit wachsender Concentration der Druckfarbe an Indigo auch vorteilhaft bei höherer Temperatur gedämpft wird. Während man

kaum in Betracht.
Zur Ausführung des Verfahrens eignet sich ein Dämpfkasten, welcher nach den in der deutschen Patentschrift Nr. 109800 angegebenen Grundsätzen gebaut ist und gestattet, die Temperatur im Innern zu messen. Vor der Benutzung wird er auf die gewünschte Temperatur geheizt. Die Ausführung des Verfahrens erleidet sonst gar keine weitere Ver- änderung.

Method of producing and attaching indigo to fiber.
In the German patents No. 108722 and No. 109800, a method for fixing indigo on the plant fiber is described, according to which it is possible to use an alkali made of indigo salt and a thickening agent, e.g. B. Dextrin
EMI1.1
to fasten by means of duction. The method consists in steaming the fabric printed with the printing ink and dried in an open steaming box - that is, without pressure - with air being connected and the fabric avoiding becoming wet.

and the fiber is reduced to soluble indigo white; this penetrates the fiber and is then oxidized again to insoluble indigo after steaming during washing and acidification.
It has now been found, when following this process further, that the temperature during steaming also has an influence on the result thereof. It has been found that for the full development of the indigo prints, which are produced with indigo printing inks with different indigo content, a different steaming temperature is required, so that with increasing concentration of the printing ink on indigo, steaming is also advantageously carried out at a higher temperature. While one

wants to achieve a more nuanced shade. The lowest limit for prints that are not too light was a temperature of 1040 C.

hardly considered.
A steam box which is built according to the principles specified in German patent specification No. 109800 and allows the temperature inside to be measured is suitable for carrying out the method. It is heated to the desired temperature before use. Otherwise, the execution of the method does not suffer any further changes.
