  Verfahren zur Herstellung echter blauer Färbungen auf Wolle. 



   Durch die Stammpatentscbrift ist ein Verfahren zur Herstellung echter blauer Färbungen auf Wolle geschützt, welches darin besteht, dass man den Farbstoff : 4-Chlor- -2-aminophenol-6-sulfosäureazo-ss-naphtolinGegenwartvonChrombeizenausfärbt. 



   Es wurde nun gefunden, dass der Farbstoff, welcher an Stelle der   4-Chlor-2-amino-     phenot-6-sulfosäun)   die 4-Methyl-2-aminophenol-6-sulfosäure enthält, ebenfalls die wertvolle Eigenschaft zeigt, sich gleichzeitig mit   Chromheize   aus einem Bade echt auf Wolle zu fixieren. Man erhält so schöne, tiefe, blaue Nuancen, die etwas röter sind als die nach dem Verfahren der Stammpaten tschrift erhältlichen. 



   Beispiel. 



   Auf 100 kg Ware (Stück, Strang oder lose Wolle) gibt man 4 kg (4% des Farbstoffs : 4-Methyl-2-aminophenol-6-sulfosäure + ss-Naphtol) der Flotte zu, kocht auf und setzt 
 EMI1.1 
 zu. Hierauf wird noch 1   bis 1# Stunden gekocht. Man erhält   so eine tiefe, dunkelblaue Färbung von hervorragender Echtheit, die den auf zwei Bädern erzielten in keiner Weise   nachsteht.

  Process for producing true blue dyeings on wool.



   A process for the production of true blue dyeings on wool is protected by the parent patent letter, which consists in dyeing the dye: 4-chloro--2-aminophenol-6-sulfonic acid azo-ß-naphtoline in the presence of chrome stains.



   It has now been found that the dye which contains 4-methyl-2-aminophenol-6-sulfonic acid instead of 4-chloro-2-aminophenol-6-sulfonic acid, also shows the valuable property of being displayed at the same time Really fix chrome heater from a bath on wool. The result is beautiful, deep, blue nuances that are a little redder than those obtainable using the method of the parent patent.



   Example.



   4 kg (4% of the dye: 4-methyl-2-aminophenol-6-sulfonic acid + ß-naphtol) are added to the liquor for every 100 kg of goods (piece, strand or loose wool), the mixture is boiled and set

 to. This is followed by 1 to 1 hours of cooking. The result is a deep, dark blue coloration of excellent fastness that is in no way inferior to that achieved in two baths.
