Verfahren zur Herstellung waschechter violetter Färbungen auf Baumwolle. Patentiert im Deutschen Reiche vom 14. Juni 1912 ab.Process for producing washable violet dyeings on cotton. Patented in the German Empire on June 14, 1912.
Es wurde gefunden, daß man zu waschechten violetten Baumwollfärbungen dadurch gelangen kann, daß man die Farbstoffe, die durch Kuppeln der Tetrazoverbindungen der Azofarbstoffe aus einem Molekül Dianisidin und einem oder zwei Molekülen ι · 6- oder ι · 7-Naphtylaminsulfosäure und zwei Molekülen Resorcin erhältlich sind, auf der Faser mit Formaldehyd behandelt. Die so erhältlichen Färbungen sind alkaliechter als die in der gleichen Weise behandelten des Farbstoffs aus tetrazotiertem Dianisidin und zwei Molekülen Resorcin.It has been found that this results in washable violet cotton dyeings can get that the dyes that are obtained by coupling the tetrazo compounds Azo dyes from one molecule of dianisidine and one or two molecules ι · 6- or ι · 7-naphthylamine sulfonic acid and two molecules Resorcinol are available on the fiber treated with formaldehyde. The so available Dyes are more alkaline than those of the dye treated in the same way from tetrazotized dianisidine and two molecules of resorcinol.

gefärbt. Die Baumwolle wird nach dem Färben gespült und ausgewaschen; darauf geht man damit ein in ein Bad, welches in 1000 Teilen 2 Teile Formaldehydlösung von 40 Prozent enthält. Man zieht in diesem Bade eine halbe Stunde um, preßt ab und trocknet. Man erhält ein waschechtes Violett.colored. The cotton is rinsed and washed out after dyeing; one goes on that thus one in a bath, which in 1000 parts 2 parts formaldehyde solution of 40 percent contains. In this bath you change clothes for half an hour, press off and dry. You get a true violet.
