Description
Verfahren zur Verbesserung der Echtheitseigenschaften von Färbungen und Drucken mit Schwefelfarbstoffen Es ist bekannt (deutsche Patentschrift 907 643), 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 known (German Patent 907 643), the fastness properties of dyeings and prints produced with sulfur dyes to improve in such a way that the dyeings and prints before the oxidation with treated fissile onium compounds so that the dye is 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, wenn man die Nachbehandlung mit wasserlöslichen Addukten aus organischen Dihalogeniden und substituierten Hydrazinen durchführt, daß dann derartige Nachteile nicht eintreten. Die Naßechtheitseigenschaften, wie Waschechtheit, Oxydations- und Reduktionsechtheit werden bedeutend verbessert, während die Lichtechtheit sowie der Farbton praktisch unbeeinflußt bleiben.Surprisingly, it has been shown when you can follow up treatment with water-soluble adducts of organic dihalides and substituted hydrazines carries out that such disadvantages then 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.
Der Vorteil derartiger Addukte gegenüber den bisher bekannten ist vor allen Dingen auch der, daß sie sich sehr leicht herstellen lassen und nicht hygroskopisch sind, so daß die Addukte als lagerbeständige Trockenpräparate in den Handel gebracht werden können. Verfahrensbeispiel 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 2 Bad behandelt, welches etwa 0,5 g des wasserlöslichen Addukts aus 1,4-Dichlorbutin-2 und N, N-Dimethyl-hydrazin enthält.The advantage of such adducts over the previously known is above all, that they can and cannot be produced very easily are hygroscopic, so that the adducts as storage-stable dry preparations in the Trade can be brought. Process Example 10 g of one containing a sulfur dye Dyed cottons are squeezed off after being removed from the dyebath and treated before oxidation in an aqueous 2 bath adjusted to pH 10 with soda, which is about 0.5 g of the water-soluble adduct of 1,4-dichlorobutyne-2 and N, N-dimethylhydrazine contains.
