Description

Verfahren zur Erzeugung von echten Färbungen und Drucken mit Küpenfarbstoffen Zusatz zuin Patent 418487 Das Hauptpatent 418 487 betrifft ein Verfahren zur Erzeugung von Färbungen und Drucken vermittels Estern von Leukoküpenfarbstoffen, welches darin besteht, daß man diese Verbindungen auf die Faser bringt und die Färbung durch Einwirkung von sauren Oxydationsmitteln oder durch Lichtwirkung entwickelt.Process for the production of real dyeings and prints with vat dyes Addition to patent 418487 The main patent 418 487 relates to a process for the production of dyeings and prints by means of esters of leuco vat dyes, which consists in bringing these compounds onto the fiber and dyeing by the action of acidic oxidizing agents or by the action of light.

In den Zusatzpatenten 433 146 und 441 371 ist weiter gezeigt worden, daß man derartige Färbungen und Drucke auch in der Weise erzeugen kann, daß man die mit den Estersalzen und einem Oxydationsmittel, gegebenenfalls in Gegenwart eines Oxydationskatalvsators, geklotzte oder bedruckte Faser dämpit. Dem Klotzbade bzw. der Druckpaste wird praktisch zweckmäßig ein Ammonsalz zugefügt.In the additional patents 433 146 and 441 371 it was further shown that such dyeings and prints can also be produced in such a way that one those with the ester salts and an oxidizing agent, optionally in the presence an oxidation catalyst, padded or printed fiber attenuates. The log bath or an ammonium salt is expediently added to the printing paste.

In dem Patent 479 678 ist ferner gezeigt worden, daß man derartige Färbungen und Drucke vorteilhaft auch in der Weise erzeugen kann, daß man mit dem Estersalz und dem Oxvdationsmittel einen in der Wärme Säure geb#enden Stoff verwendet, der in Druck-e, pasten und Klotzbädern keine Ausscheidungen bewirkt, wie z. B. Chloräthylalkohol, Diäthyltartrat, Glycerinphosphorsa*ureester u. dgl.In the patent 479 678 has been further shown that such dyeings and prints can advantageously produce in the manner that is used with the Estersalz and the Oxvdationsmittel a give in the heat acid # substance, in the prints, pastes and pad baths does not cause excretions, such as. B. chloroethyl alcohol, diethyl tartrate, glycerol phosphoric acid ester and the like.

Es ist nun weiter gefunden worden, daß man bei diesen Verfahren gleichmäßigere und intensivere Färbungen und Drucke erzielt, wenn inan in den genannten Verfahren Glycol, Monoäthylglycol oder ähnliche Stoffe mitverwendet.It has now been further found that these processes are more uniform and more intense dyeings and prints achieved when inan in the processes mentioned Glycol, monoethyl glycol or similar substances are also used.

Das Verfahren wird durch folgende Beispiele erläutert. i. Druckfarbe Estersalz von 4:4'-Dimethyl- 6: 6'-dichlorthioindigo ..... 38 Solutionssalz B (benzvlstilfanil- saures Natriuni) .......... 50 ,Nlonoäthylglycol ............ so Wasser .................... 172 Tragantli .................. 550 Natriumchloratlösung I -. 3 ... 6o Rhodanammoniumlösung i : i. 6o Ammonitinivanarlatlösung i `1, 20 1000. Drucken, trocknen, 5 bis io Minuten dämpfen, waschen, kochend seifen, waschen und trocknen. -3. Druckfarbe Estersalz von 6:61-Diätlioxy- thioindigo ............... 6o Monoäthylglycol ............ 50 Wasser .................... 225 Traganth .................. 650 Natriumnitrit .............. 15 1000. Drucken, trocknen, i bis 3 Minuten im Schwefelsätirebade (:2o cem Schwefelsäure 66' B6 in 1 1 Wasser) bei 6o' C entwickeln, waschen, kochend seifen, wasclien und trocknen.The following examples illustrate the process. i. Printing ink Ester salt of 4: 4'-dimethyl 6: 6'-dichlorothioindigo ..... 38 Solutions salt B (benzvlstilfanil- Sour Natriuni) .......... 50 , Nlonoethyl glycol ............ so Water .................... 172 Tragacanth .................. 550 Sodium Chlorate Solution I -. 3 ... 6o Rhodanammonium solution i : i. 6o Ammonitinivanarlate solution i `1, 20 1000. Print, dry, steam for 5 to 10 minutes, wash, soap at the boil, wash and dry. -3. Printing ink Ester salt of 6:61 diet dioxy thioindigo ............... 6o Monoethyl glycol ............ 50 Water .................... 225 Tragacanth .................. 650 Sodium nitrite .............. 15 1000. Print, dry, develop for 1 to 3 minutes in a sulfuric acid bath (: 2o cem sulfuric acid 66 ' B6 in 1 1 water) at 6o' C , wash, soap at the boil, wash and dry.

Die Vorteile des neuen Verfahrens sind, zum größten Teil manipulationstechnischer Art, wie bessere Löslichkeit der Estersalze in der Druckpaste, bessere Haltbarkeit der letzteren und zuverlässigeres Arbeiten. Die erhaltenen Drucke sind gleichmäßiger und intensiver als solche, die ohne Monoäthylglycol erhalten werden.The advantages of the new process are, for the most part, more manipulative Kind of like better solubility of the ester salts in the printing paste, better shelf life the latter and more reliable working. The prints obtained are more uniform and more intense than those obtained without monoethyl glycol.

An Stelle von Monoätllylglycol kann auch mit ähnlichem Resultat Glycol oder ein anderer ähnlicher Stoff verwendet werden.Instead of monoethyl glycol, glycol can also be used with a similar result or another similar substance can be used.
