Description

Verfahren zur Herstellung von Adinschwarz auf Textilstoffen ' Es ist bekannt, daß man Anilinschwarzbädern, die neben Anilinsalz ein Oxydationsmittel, eine katalytisch wirkende Metallverbindung und eine katalytisch wirkende organische Verbindung enthalten, als Faserschutzmittel große Mengen von Salzen schwacher oder leicht oxydierbarer Säuren zusetzen kann, ohne die Schwarzbildung zu hemmen. Das Verfahren hat jedoch den Nachteil, daß die Reservierung so behandelter Stoffe Schwierigkeiten macht und ein einwandfreier Schwarzton nicht zu erhalten ist.Process for the production of adin black on textile fabrics' It is known that aniline black baths which, in addition to aniline salt, contain an oxidizing agent, a catalytically active metal compound and a catalytically active organic one Compound contain, as a fiber protection agent, large amounts of salts or weak can add easily oxidizable acids without inhibiting black formation. That However, the method has the disadvantage that the reservation of substances treated in this way is difficult and a perfect black tone cannot be obtained.

Es sind auch Verfahren bekannt, bei denen an Stelle von Salzen schwacher Säuren oder neben ihnen andere Faserschutzmittel, z. B. Eiweißabbaustoffe; zur Verwendung kommen. Die zur Verwendung kommenden Mengen dieser Schutzmittel sind jedoch so gering, daß nur eine mäßige Faserschutzwirkung eintritt.There are also known processes in which, instead of salts, weaker Acids or other fiber protection agents in addition to them, e.g. B. Protein breakdowns; for use come. However, the quantities of these protective agents used are so small that that only a moderate fiber protection effect occurs.

Im Gegensatz zu diesen bekannten Verfahren ermöglicht das vorliegende Verfahren die Herstellung unvergrünlicher Anilinschwarzfärbungen und -drucke unter weitgehender Schonung der Faser, ohne daß die Reservierung der Färbungen beeinträchtigt wird. Diese Vorteile werden dadurch erreicht, daß als Faserschutzmittel reduzierend wirkende Zucker zur Anwendung kommen, und zwar in einer Menge von mindestens 250/0, berechnet auf die anzuwendenden Anilinsalzmengen. Die durch den Zucker eintretende Hemmung der Anilinschwarzbildung wird durch die gleichzeitige Anwendung von katalytisch wirkenden organischen Verbindungen neben den bereits in jeder Anilinschwarzflotte oder Druckpaste vorhandenen katalytisch wirkenden Metallverbindungen verhindert. Beispiel z Es wird eine Anilinschwarzflotte hergestellt, welche im Liter 78 g Anilinhydrochlorid, 58,5 g Kaliumferrocyanid, 32,5 g Natriumchlorat, 3,25 bis =3 g r, 4-Diaminobenzol und 19,5 bis 26 g Traubenzucker enthält..In contrast to these known methods, the present one enables Process the production of non-greenish aniline black colorations and prints extensive protection of the fiber without affecting the reservation of the colorations will. These advantages are achieved by using a reducing agent as a fiber protection agent active sugars are used, in an amount of at least 250/0, calculated on the amount of aniline salt to be used. The one entering through the sugar Inhibition of aniline blackening is achieved through the simultaneous application of catalytic active organic compounds in addition to those already in every aniline black liquor or printing paste prevents existing catalytically active metal compounds. Example z An aniline black liquor is produced which contains 78 g of aniline hydrochloride per liter, 58.5 g potassium ferrocyanide, 32.5 g sodium chlorate, 3.25 to = 3 g r, 4-diaminobenzene and contains 19.5 to 26 g of grape sugar ..

Die mit dieser Flotte getränkten Stoffe werden abgequetscht, getrocknet, 3 bis 6 Minuten gedämpft und gewaschen, wobei die übliche Nachoxydation durch heiße Chromatlösung erfolgen kann. ' Beispiel 2 Die Ware wird in einer Flotte, welche 78 g Anilinhydrochlorid, 13 g Eisensulfat, 32,5 g Natriumchlorat, 3,25 bis 13 g i, 4-Diaminobenzol, =9,5 bis 26 g Traubenzucker im Liter enthält, behandelt, abgequetscht, dann bei 5o bis 6o' C 1/2 bis z Stunde verhängt und schließlich mit Bichromat und Schwefelsäure nachbehandelt. Man erhält in beiden Fällen tiefe, unvergrünliche Anilinschwarzfärbungen.The substances soaked with this liquor are squeezed off, dried, Steamed and washed for 3 to 6 minutes, with the usual post-oxidation by hot Chromate solution can be done. 'Example 2 The goods are in a fleet, which 78 g aniline hydrochloride, 13 g iron sulfate, 32.5 g sodium chlorate, 3.25 to 13 g i, 4-diaminobenzene, = 9.5 to 26 g of grape sugar per liter, treated, squeezed off, then imposed at 5o to 6o 'C 1/2 to z hour and finally with bichromate and Sulfuric acid aftertreated. In both cases, deep, non-greenish aniline black colorations are obtained.

Sehr zweckmäßig ist die Vereinigung der organischen Katalysatoren und Zucker zu Präparaten. Diese Präparate werden den Anilinschwarzflotten oder -druckpasten in den durch die Menge des zur Anwendung kommenden Anilinsalzes bestimmten Mengenverhältnissen zugesetzt.The combination of the organic catalysts is very useful and sugar to preparations. These preparations are the aniline black liquors or printing pastes in the proportions determined by the amount of aniline salt used added.
