Description

Verfahren zum Färben von gemischten Geweben aus Wolle und Seide Die Zahl der sauren Azofarbstoffe, welche `'Volle und Seide aus einem Bade in gleicher Stärke anfärben, ist bekanntlich gering. Im Patent .113 283 ist gezeigt worden, daß solche Pyrazolonazofarbstoffe, die eine oder mehrere Carbonsäureestergruppen enthalten, sich durch eine erhöhte Affinität zur Seide auszeichnen. Es wurde nun weiter gefunden, daß auch solche Pyrazolonazofarbstoffe, die eine oder mehrere Alkyloxy-, Aryloxy- bzw. Aralkyloxygruppen enthalten, sich in hervorragender Weise zur Herstellung von Unifärbungen auf Wollseidenartikeln eignen.Method of dyeing mixed fabrics of wool and silk Die Number of acidic azo dyes which 'fullness and silk from one bath are equal Coloring starch is known to be low. In the '113,283 patent it has been shown that such pyrazolone azo dyes which contain one or more carboxylic acid ester groups contain, are characterized by an increased affinity for silk. It was now further found that those pyrazolone azo dyes which contain one or more alkyloxy, Aryloxy or aralkyloxy groups are excellent for production of solid colors on woolen silk items.

Beispiele i. i kg Wollseidenstoff wird in einem Färbebade, welches 2o g des Farbstoffes o-Ampnaol- i -(q.'-Sulfophenyl-) 3-methyl-5-pyrazolon enthält, in der für das Färben von Wollseidenstoff. üblichen Weise unter Zusatz von io °%o Glaubersalz und q. % Schwefelsäure gefärbt. Die so erhaltene Färbung zeichnet sich neben sonst guten Echtheitseigenschaften dadurch aus, daß Wolle und Seide in gleicher Tiefe und gleichem Farbton angefärbt sind. 2. Ersetzt man den in Beispiel i angegebenen Farbstoff durch die gleiche Menge des Farbstoffes: o-Aminodiphenvläther- i - (@.'- Sulfophenyl-) 3-methyl-5,-pyrazolon, so erhält man den gleichen Effekt, wie unter i ausgeführt.Examples i. i kg of woolen silk fabric is in a dye bath which contains 2o g of the dye o-Ampnaol- i - (q .'-sulfophenyl-) 3-methyl-5-pyrazolone in the for dyeing woolen silk fabric. usual way with the addition of io% o Glauber's salt and q. % Sulfuric acid colored. The dyeing obtained in this way is not only characterized by otherwise good fastness properties, but also by the fact that wool and silk are dyed to the same depth and shade. 2. If the dye given in Example i is replaced by the same amount of the dye: o-Aminodiphenvläther- i - (@ .'-sulfophenyl-) 3-methyl-5, -pyrazolone, the same effect is obtained as under i executed.

Die in den Beispielen angeführten Kombinationen können mannigfach sowohl in der Diazotierungs- wie auch in der Kuppelungskomponente variiert werden. Indessen wählt man zweckmäßig den Aufbau der Farbstoffe so, daß im Färbstoffmolekül nicht mehr saure Gruppen vorhanden sind, als zum Löslichmachen erforderlich.The combinations given in the examples can be manifold can be varied both in the diazotization as well as in the coupling component. However, it is expedient to choose the structure of the dyes so that in the dye molecule there are no more acidic groups present than necessary for solubilization.

Neben den Farbstoffen aus Beispiel r und 2 können z. B. folgende mit Vorteil angewandt werden: 3 -Amino - i - methyl-.l-phenolbenzylätheri-(q.'-Sulfophenyl-) 3-methyl-5-pyrazolon, o-Anxlinsulfosäjure- i -(q.'- Methoxyphenyl-) 3-methv 1-5-py razolon, p-Aminodiphenyläther-o-sulfosäure-i-plienyl-3-methyl-5-p3-razolon usw.In addition to the dyes from example r and 2, z. B. the following with Advantage used: 3-amino - i - methyl-.l-phenolbenzyletheri- (q .'- sulfophenyl-) 3-methyl-5-pyrazolone, o-Anxlinsulfosäjure- i - (q .'-methoxyphenyl-) 3-methv 1-5-py razolon, p-aminodiphenyl ether-o-sulfonic acid-i-plienyl-3-methyl-5-p3-razolon etc.

Die Herstellung-der Farbstoffe erfolgt in bekannter Weise, indem man auf die aus den entsprechenden Hy drazinen und Acetessigester erhältlichen Pyrazolone die Diazoverbindungen einwirken läßt. Enthalten sowohl dieDdazotierungs-als auch die Kuppelungskomponente eine Alkyloxy-, Aryloxy- bz«-. Aralkyloxygruppe, oder ist in einer Komponente eine .Äthergruppe und in der andern eine Carbonsäureestergruppe vorhanden, so wird die Affinität der Farbstoffe zur Seide noch gesteigert. Neben den angeführten Monoazofarbstoffen lassen sich auch in geeigneter Weise aufgebaute Disazofarbstoffe verwenden.The dyes are produced in a known manner by on the pyrazolones obtainable from the corresponding hy drazinen and acetoacetic esters allows the diazo compounds to act. Contain both the dazotation and the coupling component is also an alkyloxy-, aryloxy- bz «-. Aralkyloxy group, or is an .ether group in one component and a carboxylic acid ester group in the other present, the affinity of the dyes for silk is increased. Next to the listed monoazo dyes can also be built up in a suitable manner Use disazo dyes.
