Description
Verfahren zur Erzeugung wasserechter Färbungen auf der Faser. Die Echtheit der mit Hilfe von substantiven Farbstoffen mit beizenziehenden Gruppen erhältlichen Färbungen kann bekanntlich durch Nachbehandlung mit chromsauren Salzen, Fluorchrom oder auch essigsaurem Chrom verbessert werden. Angaben darüber finden sich in Knecht, R a w s o n , Löwenthal, Handbuch der Färberei, z. Auflage, Seite 869, ferner in B u n t r o c k , Handbuch des Zeugdrucks 1902, Seite i 18 bis 119, und in den Ratgebern und sonstigen Veröffentlichungen der verschiedenen Farbenfabriken.Process for producing waterfast dyeings on fibers. the Authenticity of the with the help of substantive dyes with associated groups available colors can be known by post-treatment with chromic acid salts, Fluorochrome or acetic acid chrome can be improved. Find information about it himself in Knecht, R a w s o n, Löwenthal, Handbuch der Därberei, z. Edition, page 869, also in B u n t r o c k, Handbuch des Zeugdrucks 1902, pages 18 to 119, and in the guides and other publications of the various paint factories.
In diesen Fällen muß zunächst der substantive Farbstoff heiß in der üblichen Weise aufgefärbt werden, worauf dann ebenfalls in der Wärme die Nachbehandlung mit dem Chromsalz vorgenommen wird.In these cases, the substantive dye must first be hot in the are colored in the usual way, whereupon the post-treatment is also carried out in the heat is made with the chromium salt.
Es wurde nun gefunden, daß man solche Färbungen in äußerst einfacher Weise auch so erzeugen kann, daß man die Faser zunächst bei gewöhnlicher Temperatur mit der wäßrigen Lösung des betreffenden Farbstoffs tränkt, trocknet und dann ebenfalls bei gewöhnlicher Temperatur mit einer Lösung von Chromchlorid nachbehandelt und dann noch kurze Zeit mit heißem Wasser behandelt. Für diesen Zweck sind auch Farbstoffe verwendbar, die wenig oder gar keinen substantiven Charakter besitzen. Die Färbungen sind echt gegen kochendes Wasser. Es war nicht vorauszusehen, daß das Chromchlorid diese besondere Wirkung zeigen würde, denn die bisher zur Erzeugung von Chromlacken benutzten Verbindungen, wie Bic'hromat, Fluorchrom oder essigsaures Chrom, gaben, bei gewöhnlicher Temperatur angewandt, überhaupt keine haftenden oder nur sehr magere Färbungen. Der Wegfall des Dampfverbrauchs beim Färbern und die bedeutend vereinfachte Färbeweise bedeutet gegenüber den bekannten Verfahren einen wesentlichen technischen Fortschritt.It has now been found that such dyeings are extremely easy Way can also be produced in such a way that the fiber is initially at ordinary temperature soaked with the aqueous solution of the dye in question, dried and then likewise post-treated at ordinary temperature with a solution of chromium chloride and then treated with hot water for a short time. Dyes are also used for this purpose which have little or no substantive character. The colorations are real against boiling water. It was not foreseeable that the chromium chloride this would show this special effect, because the previous generation of chrome paints used compounds, such as bic'hromat, fluorochrome or acetic chromium, gave, applied at ordinary temperature, no adhesive at all or only very meager Colorations. The elimination of steam consumption during dyeing and the significantly simplified Color proof means an essential technical one compared to the known processes Progress.
Das beschriebene neue Verfahren eignet sich ganz besonders zur Herstellung von Ja= vabatiks.The new method described is particularly suitable for production from yes = vabatiks.
Beispiel. Gelboranze aus Hessischgelb.Example. Yellow orange from Hessian yellow.
i. Farblösung: iog Hessischgelb im Liter, z. Chromchloridlösung: 3° Be.i. Color solution: iog Hessian yellow per liter, e.g. Chromium chloride solution: 3 ° Be.
Man läßt den Stoff etwa 5 Minuten bei gewöhnlicher Temperatur in der Farbstofflösung liegen, quetscht ab und trocknet. Dann legt man die so erhaltene Anfärbung etwa 5 Minuten in der Chromchloridlösung von 3° B6, quetscht ab und behandelt kurz mit heißem Wasser.The fabric is left in the for about 5 minutes at normal temperature Dye solution lie, squeezes and dries. Then you put the so obtained Staining for about 5 minutes in the chromium chloride solution at 3 ° B6, squeezes off and treated briefly with hot water.
Man erhält ein volles, feuriges Orangegelb, das vollständig echt gegen kochendes Wasser ist.You get a full, fiery orange-yellow that is completely genuine against is boiling water.
Die Stärke der benutzen Farbstofflösung, die für weitere Färbungen weiterbenutzt werden kann, hängt natürlich von der Tiefe der gewünschten Färbung ab. Das Verfahren ist ganz analog bei Verwendung anderer Beizenfarbstoffe, wie z. B. Baumwollgelb Al), Plutoorange G-), Diaminbraun MS), Walkorange 4), AzoalizarinbordeauxW5), Gallophenin usw. ( G. S c h u 1 t z, Farbstofftabellen, Auflage, 1914. 1) Nr. i99, 2) Nr. 392, Nr. 344, 4) Nr. 250, 5) Nr. 291.)The strength of the dye solution used, which can continue to be used for further dyeing, naturally depends on the depth of the desired dyeing. The process is very similar when using other mordant dyes, such as. B. cotton yellow Al), Pluto orange G-), diamine brown MS), whale orange 4), azoalizarin bordeauxW5), gallophenin etc. (G. S chu 1 tz, color tables, edition, 1914. 1) No. 199, 2 ) No. 392 , No. 344, 4) No. 250, 5) No. 291.)
