Description

Verfahren zur Verbesserung der Echtheitseigenschaften von Färbungen und Drucken mit Schwefelfarbstoffen Es ist bekannt, Schwefelfärbungen in ihren Echtheiten durch eine Nachbehandlung mit Metallsalzen oder auch mit kationaktiven Hilfsmitteln zu verbessern. Die erzielte Verbesserung bewegt sich aber meist nur in sehr bescheidenem Rahmen, was vermutlich damit zusammenhängt, daß die reaktionsfähigen Gruppen durch die vor der Behandlung eingetretene Oxydation blockiert werden bzw. daß keine stabilen Umsetzungsprodukte entstehen. Bei der bekannten Umsetzung mit monofunktionellen Alkylierungsmitteln erhält man bei manchen Färbungen wohl bessere Resultate, die erzielbare Echtheit ist aber immer noch beschränkt.Process for improving the fastness properties of dyeings and printing with sulfur dyes. It is known that the fastness properties of sulfur dyeings are known by post-treatment with metal salts or with cation-active auxiliaries to improve. However, the improvement achieved is usually only very modest Framework, which is probably related to the fact that the reactive groups through the oxidation that occurred before the treatment is blocked or that none are stable Implementation products arise. In the known implementation with monofunctional Alkylating agents give better results with some dyeings achievable authenticity is still limited.

Im Gegensatz dazu ist das vorliegende Verfahren geeignet, die Echtheitseigenschaften, so z. B. die Sodakochechtheit und die Beständigkeit gegen reduzierend wirkende Bäder, grundlegend zu verbessern, so daß die. nach dem Verfahren behandelten Färbungen und Drucke praktisch sodakochecht und völlig beständig gegen Red uktionsm@itteleinwirkung sind. Das Verfahren basiert darauf, daß die Färbungen und Drucke, solange sie noch im reduzierten Zustand vorliegen, also noch nicht oxydiert sind, mit bifunktionellen, als vernetzend wirkenden Produkten umgesetzt werden. Man arbeitet in der Weise, daß man die Färbungen aus dem schwefelnatriumhaltigen Färbebad herausnimmt und, ohne zu oxydieren, in die wäßrige Dispersion oder in die wäßrige Lösung des betreffenden Produkts eingeht und anschließend spült und trocknet. Bei der Behandlung findet eine Reaktion, zwischen den in reduziertem Zustand vorliegenden Farbstoffen und den bifunktionellen Produkten unter Bildung von Bisthi@oätbern statt, die zu sehr echten Färbungen und Drucken führt.In contrast, the present method is suitable for the fastness properties, so z. B. the fastness to soda and the resistance to reducing baths, fundamentally improve so that the. dyeings treated by the process and prints practically soda-cookable and completely resistant to the effects of reducing agents are. The process is based on the dyeing and printing while they are still present in the reduced state, i.e. not yet oxidized, with bifunctional, implemented as networking products. One works in the way that the dyeings are removed from the dyebath containing sodium sulphide and, without oxidizing, in the aqueous dispersion or in the aqueous solution of the relevant Product enters and then rinses and dries. When treating takes place a reaction between those present in a reduced state Dyes and the bifunctional products with the formation of bisthi @ oätbern instead, which lead to very real dyeings and prints.

Als erfindungsgemäße Behandlungsmittel kommen bifunktionelle Produkte, wie Äthylendichlorid, Athylendibromid usw., in Betracht. An Stelle wasserunlöslicher Produkte werden zweckmäßig wasserlösliche, in der Hitze die Halogenide abgebende quaternäre Ammonium- oder Pyridiniumverbindungen, wie z. B. das Di-pyridiniumsalz des g, io-Bis [chlormethyl] -anthracens oder N, N'-i, 4.-Buten-(2)-bis- [dimethylphenylammoniumchlorid], angewandt.The treatment agents according to the invention are bifunctional products, such as ethylene dichloride, ethylene dibromide, etc., into consideration. Instead of water-insoluble Products are expediently water-soluble and release the halides in the heat quaternary ammonium or pyridinium compounds, such as. B. the di-pyridinium salt des g, io-bis [chloromethyl] anthracene or N, N'-i, 4.-butene- (2) -bis- [dimethylphenylammonium chloride], applied.

Als Verfahrensbeispiele seien die folgenden genannt: i. Man geht mit der noch nicht oxydierten Schwefelfärbung in ein Bad ein, welches eine wäßrige Emulsion von Äthylendibromi!d enthält. Als Emulgiermittel findet z. B. ein Polyglykoläther Verwendung. Die anzuwendende Menge an Athylendibromid richtet sich nach dem Prozentsatz des angewandten Farbstoffs. Zweckmäßig wird ein gewisser Überschuß über die Farbstoffmenge angewandt. In diesem Bad wird je nach Farbstofftyp bei mäßiger Temperatur bzw. bei Temperaturen bis zu 8ö° während io Minuten behandelt, anschließend gespült und geseift.Process examples include the following: i. One goes with the not yet oxidized sulfur color in a bath, which is an aqueous emulsion contains of ethylenedibromi! d. As an emulsifier, z. B. a polyglycol ether Use. The amount of ethylene dibromide to be used depends on the percentage of the dye used. A certain excess over the amount of dye is expedient applied. In this bath, depending on the type of dye, is at a moderate temperature or at Treated temperatures of up to 80 ° for 10 minutes, then rinsed and soaped.

2. Die Färbung wird in reduziertem Zustand in einem Bad behandelt, welches eine wäßrige Lösung einer quaternären Ammoniumverbindung, z. B. das Di-pyridiniumsalz des g, io-Bis[brommethyl]-anthracens oder N, N'-i, q.-Buten-(2)-bis-dimethylphenylammoniumchlorid], enthält. Die Behandlung geschieht während io Minuten bei 7o bis go°. Anschließend wird gespült und geseift.2. The dye is treated in a reduced state in a bath, which is an aqueous solution of a quaternary ammonium compound, e.g. B. the di-pyridinium salt des g, io-bis [bromomethyl] anthracene or N, N'-i, q.-butene- (2) -bis-dimethylphenylammonium chloride], contains. The treatment is carried out for 10 minutes at 70 to 20 °. Afterward is rinsed and soaped.
