Description
Verfahren zur Verbesserung der Echtheitseigenschaften von Färbungen und Drucken mit Schwefelfarbstoffen Es ist aus der deutschen Patentschrift 907 643 bekannt, die Echtheitseigenschaften von mit Schwefelfarbstoffen erzeugten Färbungen und Drucken in der Weise zu verbessern, daß man die Färbungen und Drucke vor der Oxydation mit spaltbaren Oniumverbindungen behandelt, so daß der Farbstoff in chemischer Reaktion so umgewandelt wird, daß er eine bedeutende Verbesserung seiner Naßechtheitseigenschaften erfährt. Meist wird jedoch durch eine solche Nachbehandlung in gewissem Umfang die Lichtechtheit mehr oder weniger verschlechtert. Außerdem ist die Behandlung mit einer gewissen Änderung des Farbtons verbunden.Process for improving the fastness properties of dyeings and printing with sulfur dyes. It is from German patent specification 907 643 known, the fastness properties of dyeings produced with sulfur dyes and to improve printing in such a way that the dyeings and prints before the Oxidation treated with cleavable onium compounds, so that the dye in chemical Reaction is so converted that it has a significant improvement in its wet fastness properties learns. In most cases, however, this type of follow-up treatment will, to a certain extent, reduce the Lightfastness more or less deteriorated. Also, the treatment is with associated with a certain change in shade.
Überraschenderweise hat sich gezeigt, daß, wenn man die Nachbehandlung mit solchen quartären Oniumverbindungen durchführt, welche als tertiäre Base ein bicyclisches aliphatisches Amin vom Typus des 1,4-Diazabicyclo-2,2,2-octan (Triäthylendiamin) enthalten, dann derartige Nachteile nicht eintreten. Die Naßechtheitseigenschaften, wie Waschechtheit, Oxydations- und Reduktionsechtheit, werden bedeutend verbessert, während die Lichtechtheit sowie der Farbton praktisch unbeeinfiußt bleiben.Surprisingly, it has been shown that if you do the aftercare performs with such quaternary onium compounds, which as a tertiary base bicyclic aliphatic amine of the 1,4-diazabicyclo-2,2,2-octane (triethylenediamine) type contain, then such disadvantages do not occur. The wet fastness properties, such as fastness to washing, fastness to oxidation and reduction, are significantly improved, while the light fastness and the color tone remain practically unaffected.
Beispiel 10 g einer mit einem Schwefelfarbstoff gefärbten Baumwolle werden nach dem Herausnehmen aus dem Färbebad abgequetscht und vor der Oxydation in einem mit Soda auf pH 10 eingestellten wässerigen Bad behandelt, welches etwa 0,5 g der Oniumverbindung aus 1,4-Dichlorbutin-2 und Triäthylendiamin enthält. Die Behandlung wird während 15 Minuten bei 90° C und bei einem Flottenverhältnis von 1 : 25 vorgenommen. Abschließend wird gespült und wie üblich fertigbehandelt.Example 10 g of a cotton dyed with a sulfur dye are squeezed off after being removed from the dye bath and before oxidation treated in an aqueous bath adjusted to pH 10 with soda, which is about Contains 0.5 g of the onium compound from 1,4-dichlorobutyn-2 and triethylenediamine. the Treatment is for 15 minutes at 90 ° C and a liquor ratio of 1:25 made. Finally, it is rinsed and finished as usual.
