Description
<Desc/Clms Page number 1>
Verfahren zum Fixieren des durch Kondensation von 1-Aminoanthrachinon mit 2-Chloranthrachinon erhältlichen Dianthrachinonylamins auf der vegetabilischen Faser.
In der deutschen Patentschrift Nr. 184905 wurde gezeigt, dass Anthrachinonylamine, welche 3 Anthrachinonkerne enthalten, Baumwolle in der Küpe anzufärben vermögen. Von Dianthrachinonylaminen sind küpenfärbende Eigenschaften bisher nicht bekannt geworden ; eine grosse Anzahl derselben, z. B. das a-a-Dianthrachinonylamin weisen vielmehr absolut keine küpenfärbenden Eigenschaften auf.
Es wurde nun die überraschende Beobachtung gemacht, dass das nach der deutschen Patentschrift Nr. 174699 erhältliche Dianthrachinonylamin im Gegensatz zu anderen Dianthrachinonimiden sich in hervorragender Weise als Küpenfarbstoff verwenden lässt.
Auf ungebeizter vegetabilischer Faser erzielt man mit ihm orangefarbene Nüancen von

lösung, fügt darauf die Farbstofflösung durch ein Sieb zu und versetzt noch mit einer Lösung von 40 bis 60 kg Glaubersalz. Man rührt nunmehr gut um und lässt einige Minuten stehen. Hierauf führt man 100 kg gut angefeuchtete Baumwolle ein und behandelt 3/. 1 bis 1 Stunde im kalten Färbebade. Nach dem Färben wird die Baumwolle herausgenommen, abgewunden, gewaschen und in schwefelsäurehaltigem Wasser (1 bis 2 cm- Schwefelsäure HG B im Liter) abgesäuert, gewaschen und geseift. Man erhält so sehr echte orange Töne von grosser Klarheit, wie sie bisher mit keinem direkten Farbstoff erreicht worden sind.
Das Drucken verläuft in analoger Weise.

Process for fixing the dianthraquinonylamine obtainable by condensation of 1-aminoanthraquinone with 2-chloroanthraquinone on the vegetable fiber.
In the German patent specification No. 184905 it was shown that anthraquinonylamines, which contain 3 anthraquinone nuclei, are able to stain cotton in the vat. Vat-coloring properties of dianthraquinonylamines have not yet become known; a large number of them, e.g. B. the a-a-dianthraquinonylamine rather have absolutely no vat-coloring properties.
The surprising observation has now been made that the dianthraquinonylamine obtainable according to German patent specification No. 174699, in contrast to other dianthraquinonimides, can be used in an excellent way as a vat dye.
Orange nuances of can be achieved with it on unpickled vegetable fibers

solution, then adds the dye solution through a sieve and a solution of 40 to 60 kg of Glauber's salt is added. Now stir well and let stand for a few minutes. 100 kg of well-moistened cotton are then introduced and treated 3 /. 1 to 1 hour in the cold dye bath. After dyeing, the cotton is removed, unwound, washed and acidified, washed and soaped in water containing sulfuric acid (1 to 2 cm sulfuric acid HG B per liter). You get so very true orange tones of great clarity, as they have not been achieved with any direct dye.
Printing is done in the same way.
