Verfahren zur Herstellung von echten braunen und schwarzen Tönen auf Wolle.
Es wurde gefunden, dass die Farbstoffe, zu denen man durch Kombination der Diazo- verbindungen aus Nitro-2-aminophenolen, ihren Homologen oder Halogenderivaten, mit -Naphtol gelangt, sich dadurch auszeichnen, dass sie Wolle in einem Bade unh r Zusatz von Chrombeizen in sehr echten braunen bis schwarzen Nuancen anfärben. Es muss als überraschend bezeichnet werden, dass die nach vorliegendem Verfahren erhältichen Färbungen, trotzdem sich die Farbstoffe in saurem Bade kaum lösen, vollständig reibecht sind.
Vor den Farbstoffen aus diazotierten Nitroaminophenolen und Dioxychinolin, Aminonaphtolen, m-Oxydimethylanilin und p-Chlorphenol unterscheiden sich die nach vorliegendem Verfahren benutzten Farbstoffe sowohl durch ihre wertvolleren Nuancen als auch durch eine bessere Potting-bzw. Waschechtheit.
Beispiel.
EMI1.1
stoffs : 6-Chloro-4-nitro-2-aminophenol + #225-Naphtol, oder der entsprechenden Menge des in Pastenform gebrachten Farbstoffs, der Flotte zu, kocht auf und setzt 2 kg Chromkali nach, geht mit dem Material bei zirka G () bis 800 C ein, treibt langsam zum Kochen, kocht annähernd drei Viertelstunden und setzt dann allmählich 2 his 3 t Essigsäure nach. Hierauf wird noch 1 bis 11/2 Stunden gekocht. Man erhält so eine tiefe dunkelbraune Färbung von vorzüglicher Licht,- Walk- und Reibechtheit.
Verwendet man statt obigen Farbstoffs den entsprechenden ans 4-Nitro 2-amino- phenol oder Nitroamino-o-kresol, so wird ein etwas röteres Braun erhalten. Bei Benutzung
EMI1.2
Nitroamino-p-kresolen werden schwarze Töne erhalten.

Process for the production of real brown and black tones on wool.
It has been found that the dyes, which are obtained by combining the diazo compounds from nitro-2-aminophenols, their homologues or halogen derivatives, with -naphtol, are distinguished by the fact that they are added to wool in a bath without the addition of chrome stains color very real brown to black nuances. It must be described as surprising that the dyeings obtained by the present process are completely rubfast, despite the fact that the dyes hardly dissolve in an acid bath.
The dyes used in the present process differ from the dyes from diazotized nitroaminophenols and dioxyquinoline, aminonaphthols, m-oxydimethylaniline and p-chlorophenol both in their more valuable nuances and in better potting or potting. Washfastness.
Example.
EMI1.1
Substance: 6-chloro-4-nitro-2-aminophenol + # 225-naphtol, or the corresponding amount of the dye made in paste form, add to the liquor, boil and add 2 kg of potassium chromium, goes with the material at about G ( ) to 800 C, slowly boil, boil for approximately three quarters of an hour and then gradually add 2 to 3 tons of acetic acid. It is then cooked for 1 to 11/2 hours. This gives a deep, dark brown coloration of excellent light, boiled and rub fastness.
If the corresponding 4-nitro-2-aminophenol or nitroamino-o-cresol is used instead of the above dye, a somewhat redder brown is obtained. When in use
EMI1.2
Nitroamino-p-cresols are obtained in black tones.
