Description

Verfahren zur Herstellung von echten Drucken auf der pflanzlichen Faser In dem Patent 2 8 4 8 5 6 ist gezeigt worden, daß man Chromverbindungen von chromierbaren Azofarbstoffen zur Herstellung von ech.-ten Drucken verwenden kann, indem man sie auf die Faser aufdruckt und däxnpft. Manche chromierten Azofarbstoffe lassen sich indessen nur schwierig oder gar nicht auf der -pflanzlichen Faser fixieren.Process for the production of real prints on the vegetable fiber In the patent 2 8 4 8 5 6 it has been shown that one can use chromium compounds of chromable azo dyes for the production of real prints by printing them on the fiber and dipping them. However, some chromated azo dyes are difficult or impossible to fix on the vegetable fiber.

Es wurde nun gefunden, daß man ganz allgemein mit Chromverbindungen von chromierbare Gruppen enthaltenden Azo- oder Oxyazofarbstoffen auch auf der pflanzlichen Faser Drucke von vorzüglicher Echtheit erzielen kann, wenn man sie in Form stark saurer Druckpasten, die freie organische Säuren und daneben Baumwollbeizen enthalten, anwendet. Diese so erhältlichen Drucke sind meist schon nach fünf Minuten langem Dämpfen im Matherplatt sehr gut fixiert.It has now been found that chromium compounds can be used very generally of azo or oxyazo dyes containing chromable groups also on the vegetable Fiber prints of excellent authenticity can be achieved if they are strong in shape acidic printing pastes that contain free organic acids and also cotton stains, applies. These prints that can be obtained in this way are usually already after five minutes Steaming in the Matherplatt very well fixed.

Beispiel i Eine aus 3o Teilen der Chromverbindung des Azofarbstoffes aus 5-Nitro-2-ainiuophenol und 2-Naphthylamüi-5-sulfonsäure, 5o Teilen Thiodiglykol, ioo Teilen 3o9rozentiger Essigsäure, 8o Teilen essigsaurem Chrom, 640 Teilen . Essigsäure-Stiärke-Tragant-Verdickung und ioo Teilen Wasser hergestellte Paste wird auf Baumwolle aufgedruckt. Dann wird fünf Minuten im Matherplatt oder auch eine Stunde im Kessel gedäm#pft, gespült und geseift. Man erhält so ein lebhaftes lichtechtes Blaugrün.EXAMPLE i One of 30 parts of the chromium compound of the azo dye from 5-nitro-2-amino phenol and 2-naphthylamine-5-sulfonic acid, 50 parts of thiodiglycol, 100 parts of 309% acetic acid, 80 parts of chromium acetic acid, 640 parts . Acetic acid-starch-tragacanth-thickening and 100 parts of water made paste is printed on cotton. Then five minutes in the Matherplatt or one hour in the kettle steamed, rinsed and soaped. A vivid, lightfast blue-green is obtained in this way.

B-6iSpilel 2 Eine gemäß Beispieli aus der Chromverbindung des Azofarbstoffes aus i-Aminonaphth01-4-sulfOnsäure und i-Naphthol-8-sulfonsäure hergestellte Paste, die auf 3o Teile Farbstoffchromverbind:ung 25 Teile ess#gsaures Chrom enthält, liefert nach der Arbeitsweise des Beispiels i auf Baumwolle ein lebhaftes Blau.B-6iSpilel 2 A paste prepared according to Example 1 from the chromium compound of the azo dye from i-aminonaphth01-4-sulfonic acid and i-naphthol-8-sulfonic acid, which contains 25 parts of acidic chromium per 30 parts of dye chromium compound, provides after the procedure example i on cotton is a vivid blue.
