werden in heißem Wasser unter Zusatz, von 10 ecm Natronlauge 40 ° Be. gelöst und nach Hinzufügen von 20 ecm Türkischrotöl mit Wasser auf 1 1 eingestellt. Mit dieser Lösung klotzt man den gebleichten Baumwollstoff bei gewöhnlicher Temperatur und entwickelt entweder in noch feuchtem Zustand oder. besser nach dem Trocknen mit einer Lösung aus diazotiertem p-Nitranilin. Sodann spülen, leicht seifen und trocknen.are in hot water with the addition of 10 ecm caustic soda 40 ° Be. dissolved and after adding 20 ecm of Turkish red oil with Water set to 1 1. This solution is used to pad the bleached cotton fabric Ordinary temperature and developed either when still moist or. better after drying with a solution diazotized p-nitroaniline. Then rinse, soap lightly and dry.
Ρλτκν τ-An spruch:
Verfahren zur Erzeugung schwarzer Färbungen auf der Faser, dadurch gekennzeichnet,
daß man die durch Kuppeln eines p-Diamins mit einer zweimal kombinationsfähigen
ι · 8-Aminonaphtolsulfosäure in saurer
Lösung einerseits und 1 · 8-Naphtylendiamin
oder dessen Acetonverbindung andererseits erhältlichen Azofarbstoffe auf
der Faser mit Diazoverbindungen vereinigt.Ρλτκν τ claim:
Process for producing black dyeings on the fiber, characterized in that the azo dyes obtainable on the fiber by coupling a p-diamine with a twice combinable ι · 8-aminonaphthol sulfonic acid in acidic solution on the one hand and 1 · 8-naphthylenediamine or its acetone compound on the other hand Diazo compounds combined.
