Description

Verfahren zum Färben von Acetatseide Wie gefunden wurde, färben Azofarbstoffe, welche eine Dioxydialkylaminogruppe enthalten, Acetatseide ausgezeichnet an. Die Färbungen zeichnen sich durch Klarheit, Wasch-, Wasser-und Lichtechtheit aus. Die Farbstoffe zeigen außerdem ein gewisses Egalisierungsvermögen, das bei den bekannten Suspensionsfarbstoffen für Acetatseide nicht beobachtetworden ist. Man gewinnt z. B. solche Farbstoffe, indem man beliebigeDiazoverbindungen, besonders derBenzol-oder Naphthalinreihe, mit den N-Dioxydialkylderivaten aromatischer Amine kuppelt.Method of dyeing acetate silk As has been found, azo dyes dye which contain a dioxydialkylamino group, acetate silk is excellent. the Dyeings are distinguished by their clarity, washfastness, waterfastness and lightfastness. the Dyes also show a certain leveling power, which is the case with the known ones Suspension dyes for acetate silk has not been observed. One wins z. B. such dyes by adding any diazo compounds, especially benzene or Naphthalene series, coupled with the N-dioxydialkyl derivatives of aromatic amines.

Beispiel ioo Teile Acetatseide färbt man während 3o bis 45 Minuten bei 6o bis 7o° unter Zusatz von Seife in einer Suspension von 2,5 Teilen 4-Nitranilin-azo-dioxydiäthylanilin in Wasser und spült dann kurz. Man erhält ein klares gelbliches Rot.Example 100 parts of acetate silk are dyed for 30 to 45 minutes at 6o to 7o ° with the addition of soap in a suspension of 2.5 parts of 4-nitroaniline-azo-dioxydiethylaniline in water and then rinse briefly. A clear yellowish red is obtained.

In gleicher Weise liefert 3 ; 4, 5-Trichloranilinazo-dioxydiäthylanüin ein klares Orange, 4-Nitranilin-azo-dioxydiäthyl- 3 -ammo- i -methylbenzol.einsattesgelblichesRot, 2, 4-Dinitranilinazo-dioxydiäthyl- 3 -amino- i -methylbenzol ein tiefes blaustichiges Bordeaux.In the same way, 3; 4,5-Trichloroanilinazo-dioxydiäthylanüin a clear orange, 4-nitroaniline-azo-dioxydiethyl- 3 -ammo- i -methylbenzene, a deep yellowish red, 2,4-Dinitranilinazo-dioxydiethyl-3-amino-i-methylbenzene has a deep bluish cast Bordeaux.
