Färbebeispiele:Coloring examples:

  • 1. Eine Stückware, die in Kette und Schuß aus einem Polyester-Stapelfasergarn besteht, wird auf einer Jet-Färbeanlage im Flottenverhältnis von 1 : 15 in ein auf 50 - 60°C erwärmtes Färbebad eingebracht, das je Liter 0,2 g Farbstoff der Formel
    Figure imgb0002
     und 1,5 g Egalisiermitteleinstellung 2 enthält. Der pH-Wert des Bades wird mit 2 g/l Natriumdihydrogenphosphat und Essigsäure auf pH 4,5 - 5 eingestellt. Die so beschickte Färbeflotte wird in 90 Minuten auf 130°C erhitzt und 30 Minuten bei dieser Temperatur gehalten. Nach Abkühlen und Spülen erhält man eine gleichmäßig gefärbte, dunkle Rotfärbung. Hervorzuheben ist, daß während des Färbens, Abkühlens und Spülens trotz intensiver Flottenbewegung keinerlei Schaum in der Jet-Färbeanlage festzustellen war.
    Ein ähnlich gutes Ergebnis erzielt man, wenn man anstelle der Egalisiermitteleinstellung 2 die Egalisiermitteleinstellungen 1, 3 - 8 einsetzt.    1. A piece goods, which consists of a polyester staple fiber yarn in warp and weft, is introduced on a jet dyeing machine in a liquor ratio of 1:15 into a dye bath heated to 50-60 ° C., which contains 0.2 g of dye per liter formula
    Figure imgb0002
     and contains 1.5 g leveling agent setting 2. The pH of the bath is adjusted to pH 4.5-5 with 2 g / l sodium dihydrogen phosphate and acetic acid. The dye liquor charged in this way is heated to 130 ° C. in 90 minutes and held at this temperature for 30 minutes. After cooling and rinsing, an evenly colored, dark red color is obtained. It should be emphasized that during the dyeing, cooling and rinsing, despite intensive liquor movement, no foam was found in the jet dyeing system.
    A similarly good result is achieved if you use leveling agent settings 1, 3 - 8 instead of leveling agent setting 2.
  • 2. Kreuzspulen aus einem texturierten Polyester-Filamentgarn werden im Flottenverhältnis von 1 : 10 in ein auf 60 - 70°C erwärmtes Färbebad gebracht, das je Liter 0,25 g des Farbstoffs der Formel

     und 2 g der Egalisiermitteleinstellung 1 enthält. Der pH-Wert des Bades wird mit 1 g/l Natriumdihydrogenphosphat und Essigsäure auf pH 4,5 - 5 eingestellt. Die so beschickte Färbeflotte wird in 90 Minuten auf 130°C erhitzt und 30 Minuten bei dieser Temperatur gehalten. Nach Abkühlen und Spülen erhält man eine gleichmäßig gefärbte, dunkle Rotfärbung. Hervorzuheben ist, daß während des Färbens, Abkühlens und Spülens trotz intensiver Flottenbewegung keinerlei Schaum in der Jet-Färbeanlage festzustellen war.
    Ein ähnlich gutes Ergebnis erzielt man, wenn man anstelle der Egalisiermitteleinstellung 1 die Egalisiermitteleinstellungen 2 - 8 einsetzt.    2. Cross-wound bobbins made of a textured polyester filament yarn are placed in a liquor ratio of 1:10 in a dye bath heated to 60-70 ° C., which contains 0.25 g of the dye of the formula per liter
    Figure imgb0003
     and 2 g of leveling agent setting 1 contains. The pH of the bath is adjusted to pH 4.5-5 with 1 g / l sodium dihydrogen phosphate and acetic acid.

It should be emphasized that during the dyeing, cooling and rinsing, despite intensive liquor movement, no foam was found in the jet dyeing system.
    A similarly good result can be achieved by using leveling agent settings 2 - 8 instead of leveling agent setting 1.
