Description

Verfahren zum Färben von Gebilden aus Superpolyamiden oder -urethanen Zusatz zum Patent 886 293 Gegenstand des Patents 886 293 ist ein Verfahren zum Färben von Gebilden aus Superpolyamiden oder -urethanen, das darin besteht, daß man die Gebilde mit neutralen wäßrigen Lösungen oder Suspensionen von Chromkomplexverbindungen von Azofarbstoffen, die mindestens eine Sulfonamidgruppe enthalten, aber von Sulfonsäuregruppen frei sind, behandelt.Process for dyeing structures made from superpolyamides or super-urethanes Addendum to Patent 886 293 The subject of patent 886 293 is a process for dyeing of structures made of super polyamides or urethanes, which consists in the fact that the Forms with neutral aqueous solutions or suspensions of chromium complex compounds of azo dyes that contain at least one sulfonamide group, but of sulfonic acid groups are free, treated.

Es wurde nun gefunden, daß man Gebilde aus Superpolyamiden oder -urethanen ebenfalls sehr gleichmäßig färben kann, wenn man sie mit neutralen wäßrigen Lösungen oder Suspensionen von sulfongruppenfreien Chromkomplexverbindungen von Azomethinfarbstoffen, die mindestens eine Sulfonamidgruppe enthalten, behandelt. Man erhält so ebenfalls Färbungen von besserer Wasser- und Waschechtheit als mit den entsprechenden Sulfonsäuregruppen enthaltenden Farbstoffen aus saurem Bad.It has now been found that structures made from superpolyamides or super-urethanes can be used can also be colored very evenly if you use neutral aqueous solutions or suspensions of sulfone group-free chromium complex compounds of azomethine dyes, which contain at least one sulfonamide group, treated. One also obtains in this way Dyeings of better water and wash fastness than with the corresponding sulfonic acid groups containing dyes from acid baths.

Die Färbeweisen der zu färbenden Gebilde sind die gleichen wie die des Hauptpatents.The dyeing methods of the structures to be colored are the same as that of the main patent.

Die in folgendem Beispiel genannten Teile sind Gewichtsteile.The parts mentioned in the following example are parts by weight.

Beispiel " io g der komplexen Chromverbindung des Azomethinfarbstoffes aus i-Amino-2-oxy-benzol-5-sulfonsäureamid und 2-Oxybenzaldehyd werden in 5o 1 Wasser gelöst und ioo g Natriumsulfat hinzugefügt. In diesem Bad werden iooo g Superpolyamidfasern i Stunde lang bei Kochtemperatur gefärbt. Unter vollständiger Erschöpfung des Bades erhält man gleichmäßige, klare Gelbfärbungen von sehr guter Waschechtheit. Auf Superpolyurethanfasern werden ähnliche Färbungen erzielt.Example of the complex chromium compound of the azomethine dye i-Amino-2-oxy-benzene-5-sulfonic acid amide and 2-oxybenzaldehyde are dissolved in 5o 1 of water dissolved and added 100 g of sodium sulfate. Iooo g of super polyamide fibers are used in this bath Colored for i hour at boiling temperature. With complete exhaustion of the bath uniform, clear yellow colorations of very good wash fastness are obtained. on Super polyurethane fibers produce similar colorations.
