Description

Verfahren zum Ätzen und Entwickeln von Färbungen Zusatz zum Patent 651 6o7 Gegenstand des Patents 6516o7 ist @eirne Vorrichtung, die zum Entwickeln der Färbung auf Waren dient, welche mit Küpenfarbstoffen bedruckt sind.Process for etching and developing colorations. Patent addendum 651 6o7 The subject of the patent 6516o7 is @eirne device which is used for developing is used for coloring goods which are printed with vat dyes.

Es wurde nun gefunden, daß sich diese Vorrichtung auch zum Ätzen von Färbungen auf Textilstoffen verwenden läßt. Beispielsweise kann man folgendermaßen verfahren: Man -färbt die Ware mit dem Farbstoff Nr. 6o8 der Farbstofftabellen von S c h -u 1 t z, 7. Auflage, bedruckt mit einer Ätzpaste, bestehend aus I 5o g Natriumsulfoxylat 25o g Wasser 6oo g Stärke-Tragant-Verdickung Iooog - und führt die getrocknete Ware durch die im Patent 651 607 beschriebene Vorrichtung, wobei eine Wärmestrahlung von etwa i 2o bis 170' C auf die Ware einwirkt.It has now been found that this device can also be used for etching dyeings on textile fabrics. For example, one can proceed as follows: The goods are dyed with dye no. 6o8 of the dye tables of S ch -u 1 tz, 7th edition, printed with an etching paste consisting of I 50 g sodium sulfoxylate 250 g of water 600 g starch-tragacanth thickening Iooog - and guides the dried goods through the device described in patent 651 607 , with thermal radiation of about 12 to 170 ° C. acting on the goods.

In gleicher Weise kann auch die Entwicklung von Anilinschwarz oder ähnlichen Entwicklungsfärbungen oder zum Entwickeln der Färbung aus Mischungen von substantiven Azokomponenten mit beständigen Diazoverbindungen, die durch Säure in kupplungsfähige Diazoverbindungen umgewandelt werden, ausgeführt werden. Bei der Hierstellung der zuletzt genannten Färbungen wird die zur Entwicklung erforderliche Essigsäure oder Ameisensäure entweder durch eine Spritzdüse in die Entwicklungsvorrichtung eingeblasen oder in das Wassergefäß der Vorrichtung, in dem die zusätzliche Feuchtigkeit durch Kochen erzeugt wird, eingebracht.In the same way the development of aniline black or similar development colors or to develop the color from mixtures of substantive azo components with stable diazo compounds that are converted into couplable diazo compounds are converted, are carried out. In the Here the last-mentioned colorations are required for development Acetic acid or formic acid either through a spray nozzle into the developing device blown or into the water vessel of the device, in which the additional moisture is generated by cooking, introduced.

Beispielsweise verfährt man folgendermaßen: Auf weiße Ware wird nach dem aus dem Patent 562 623 bekannten Verfahren eine Druckpaste aufgedruckt, die als farbstoffbildende Bestandteile die Diazoaminoverbindung aus 5-Chlor-2-methyl-i-aininobenzol und i-Aminobenzol-2-carbonsäure-5-sulfionsäure sowie das Natriumsalz des i-(2', 3'-Oxynaphthoylamino)-2-äthoxyb:en7jols (vgl. Patentschrift 534 640) enthält. Man bedruckt dann in üblicher Weise mit einer Weißreserve folgender Zusammensetzung: 8o g Natronlauge 4o° B6 5009 neutrale Stärke-Tragant-Verdickung 25og Zinkoxyd i : i . 8o g 1\?atriumthiosulfat und 9o g Wasser I ooo g Nach dem Drucken und Trocknen wird die Ware mit einem Anilinschwarzklotzbad behan- Belt, unmittelbar . darauf auf einer Trockenzylindermaschine getrocknet und meiner Vor-- richtung nach Patent 651 @o7 entwickelt.For example, the procedure is as follows: A printing paste is printed onto white goods using the method known from patent 562 623, which contains the diazoamino compound of 5-chloro-2-methyl-i-aininobenzene and i-aminobenzene-2-carboxylic acid-5 as the dye-forming constituent sulfionic acid and the sodium salt of i- (2 ', 3'-oxynaphthoylamino) -2-ethoxyb: en7jols (cf. patent 534 640). Printing is then carried out in the usual way with a white reserve of the following composition: 8o g caustic soda 40 ° B6 5009 neutral starch-tragacanth thickening 25og zinc oxide i: i. 8o g 1 \ atrium thiosulphate and 90 g of water I ooo g After printing and drying, the goods are treated with an aniline black block bath. Belt, immediately. then dried on a drying cylinder machine and developed in my device according to patent 651 @ o7.
