Description
Verfahren zur Verbesserung der Echtheitseigenschaften von Färbungen und Drucken mit Schwefelfarbstoffen Es ist bekannt (deutsche Patentschrift 907 643), die Echtheitseigenschaften von Färbungen und Drucken in der Weise zu verbessern, daß man die Färbungen bzw. Drucke vor der Oxydation mit bi- oder polyfunktionellen Halogeniden nachbehandelt.Process for improving the fastness properties of dyeings and printing with sulfur dyes It is known (German Patent 907 643), to improve the fastness properties of dyeings and prints in such a way that that the dyeings or prints before the oxidation with bi- or polyfunctional Post-treated halides.
Da die betreffenden Halogenide nicht wasserlöslich sind, wurde vorgeschlagen, diese in wasseremulgiertem Zustand anzuwenden. Unter diesen Umständen findet aber nur eine langsame und unvollständige Reaktion mit den Schwefelfarbstoffen statt.Since the halides in question are insoluble in water, it was suggested that to use them in a water-emulsified state. Under these circumstances, however, takes place only a slow and incomplete reaction with the sulfur dyes takes place.
Überraschenderweise hat sich gezeigt, daß man die Umsetzung mit den Halogeniden oder auch mit Halogenhydrinen auch in wäßriger Lösung durchführen kann, wenn man unter Zusatz von solchen Lösungsmitteln arbeitet, die sich mit Wasser mischen und die auch in der wäßrigen Mischung ein starkes Lösevermögen für die Dihalogenide besitzen. In Betracht kommen als Lösungsmittel z. B. N-Dialkylcarbonsäureamide, wie Dimethylformamid oder auch Dimethylsulfoxyd oder Methyläthylketon. Als Halogenide kommen z. B. Dichlorbutin und Dichlorbuten, als Halogenhydrine Epichlorhydrin und 1,3-Dichlorpropanolin Frage.Surprisingly, it has been shown that the implementation with the Can carry out halides or with halohydrins also in aqueous solution, if you work with the addition of solvents that mix with water and which also have a strong dissolving power for the dihalides in the aqueous mixture own. Suitable solvents are, for. B. N-dialkylcarboxamides, such as dimethylformamide or dimethyl sulfoxide or methyl ethyl ketone. As halides come z. B. dichlorobutine and dichlorobutene, as halohydrins and epichlorohydrin 1,3-dichloropropanolin question.
Beispiel 10 g einer mit einem Schwefelfarbstoff gefärbten Baumwolle werden nach dem Herausnehmen aus dem Färbebad abgequetscht und vor der Oxydation 15 Minuten bei 90°C in einem wäßrigen Bad (Flottenverhältnis 1: 20), welches etwa 10 °/o Dimethylformamid und etwa 0,3 g 1,4-Dichlorbutin-(2) enthält, behandelt. Das in Dimethylformamid gelöste 1,4-Dichlorbutin-(2) wird kurz vor der Nachbehandlung in das heiße Be-, handlungsbad gegeben.Example 10 g of a cotton dyed with a sulfur dye are squeezed off after being removed from the dye bath and before oxidation 15 minutes at 90 ° C in an aqueous bath (liquor ratio 1:20), which is about 10% of dimethylformamide and about 0.3 g of 1,4-dichlorobutyn- (2) contains, treated. The 1,4-dichlorobutyn- (2) dissolved in dimethylformamide is shortly before the aftertreatment put in the hot treatment bath.
