Description

Bekannt ist, daß Färbungen von Direktfarbstoffen auf Baumwolle und -riegenerieirter Cellulose im allgemeinen nur mäßige Naßechtheiten aufweisen. Es wurde nun gefunden, daß sich die Echtheiten derartiger Färbungen durch Nachbehandlung mit wäßrigen Lösungen der aus Amino- oder Iminogruppen enthaltenden. Kohlenstoffverbindungen, Formaldehyd und Ammoniumsalzen nach PatentIt is known that dyeings of direct dyes on cotton and wool Cellulose generally have only moderate wet fastness properties. It has now been found that the fastness properties of such dyeings are improved by aftertreatment with aqueous solutions those consisting of amino or imino groups. Carbon compounds, formaldehyde and ammonium salts according to patent

ίο 671704 in neutraler oder schwach, saurer Lösung hergestellten Kondensationsverbindungen verbessern lassen/. Auch Kondansationsverbiradungen aus ringförmigen Stickstoffbasan, die wie Iminoverbindungen reagieren, Formaldehyd und Ammoniumsalzen können verwendet werden.ίο 671704 in neutral or weak, acidic Solution produced condensation compounds let improve /. Also condensation connections from ring-shaped nitrogen basans, which react like imino compounds, Formaldehyde and ammonium salts can be used.

Gegenüber bekannten Nachbehandlungsmitteln für Substantive Färbungen weisen die eiündungsgemäß verwendeten Nachbehandlungismittel teilweise eine verbesserte Wirkung, insbesondere hinsichtlich Wasch-und Schweiß-■echtheitsveirbesserung auf. Die erfindüngsgemäß verwendeten Nachbehandlungsmittel haben ferner den Vorzug, den Farbton der damit behandelten Färbungen nicht oder kaum zu verändern. Gegenüber den in der französischen Patentschrift 779 583 als Nachbehandliungsmittel vorgeschlagenen, peralkylierten Polyalkylenpolyaminen zeichnen sich die erfindungsgemäß zu verwendenden Mittel zum Teil noch dadurch, aus, daß sie im trockenen Zustand hellfarbige Pulver dar-Compared to known aftertreatment agents for nouns colorations, the Post-treatment agents used as intended partly an improved effect, in particular with regard to washing and perspiration improvement on. The aftertreatment agents used according to the invention also have the advantage of not changing the hue of the dyeings treated therewith, or hardly at all to change. Compared to that in French patent specification 779 583 as an aftertreatment agent proposed, peralkylated polyalkylenepolyamines are distinguished by the According to the invention to be used agents partly still characterized in that they are in dry state light-colored powder

stellen und daher besser zu handhaben sind als die braunen, salbenartigen Stoffe das französischen Patents.and are therefore easier to handle than the brown, ointment-like substances of the French Patents.

Beispiel ιExample ι

Eine nach dem üblichen Verfahren hergestellte Färbung· von 6% Direkttief schwarz EW extra (vgl. Schultz, Farbstofftabellen, 7. Auflage, Nr. 671) auf Baumwolle wird mit 10 ecm im Liter einer nach Patent 671 704, Beispiel 5, hergestellten Lösung aus Anilin, Formaldehydund Ammoniumchlorid Va Stunde bei Zimmertemperatur nachbehandelt, gespült und getrocknet. Die erhaltene Färbung ist in ihrer Wasserechtheit wesentlich verbessert.A coloration produced by the usual method of 6% direct deep black EW extra (cf. Schultz, Dye Tables, 7th Edition, No. 671) on cotton is included with 10 ecm per liter according to patent 671 704, Example 5, solution prepared from aniline, formaldehyde and ammonium chloride Va hour aftertreated at room temperature, rinsed and dried. The color obtained is in their water fastness significantly improved.

Benutzt man zur Nachbehandlung das Kondensationsprodukt aus Dicyandiamid, Formaldehyd und Ammoniume'hlorid (Beispiel 2 des Patents 671 704), so wird nicht nur die Wassereehtheit, sondern auch die Waschechtheit verbessert.The condensation product of dicyandiamide and formaldehyde is used for aftertreatment and Ammoniume'hlorid (Example 2 of the patent 671 704), so not only Water resistance, but also improves the wash fastness.

Beispiel 2Example 2

Baumwolle wird wie üblich mit 2% Benzopurpurin (vgl. Schultz, Farbstofftabellen, 7. Auflage, Nr. 448) gefärbt, gespült und dann mit der wäßrigen Lösung des Kondensationserzeiugnisses aus 2-Methylchinolin, Formaldehyd und Ammoniumchlorid, entsprechend Patent 671 704 hergestellt, nachbehandelt. Die Wasserechtheit ist gegenüber der unbehandelten Färbung bedeutend verbessert. As usual, cotton is made with 2% benzopurpurine (see Schultz, dye tables, 7th edition, No. 448) colored, rinsed and then with the aqueous solution of the condensation product from 2-methylquinoline, formaldehyde and ammonium chloride, accordingly U.S. Patent 671,704, post-treated. The water fastness is opposite the untreated color significantly improved.

An Stelle des obigen Kondensationserzeugnisses aus 2-Methylchinolin kann auch ein solches aus 8-Am'ino-2-methylchinolin oder sein Kupferkomplex verwendet werden.Instead of the condensation product above from 2-methylquinoline can also be one from 8-amino-2-methylquinoline or its copper complex can be used.

Beispiel 3Example 3

Eine 2°/oige Färbung von. Benzolichtrot 8BL (vgl. Schultz, Farbstofftabellen 7. Auflage·, Nr. 566) wird mit der wäßrigen Lösung des Kondensationserzeugnisses aus Dodecylamin, Formaldehyd und Ammoniumsalzen (Beispiel 4 des Patents 671 704), nachbehandelt. Man erhält eine Färbung mit verbesserter Wasserechthek.A 2% coloration of. Benzolichtrot 8BL (see Schultz, color tables 7th edition, No. 566) is mixed with the aqueous solution of the condensation product of dodecylamine, Formaldehyde and ammonium salts (example 4 of patent 671 704), after-treated. A coloration with improved water retention is obtained.

An Stelle des obigen Kondensationserzeugnisses können auch die ebenso hergestellten Kondensationserzeugnisse aus Stearylamin, Dimethylanilin oder polymeren Äthylendiaminen verwendet werden. Bei Verwendung des Erzeugnisses aus Stearylamin wird auch der Griff der Ware verbessert.Instead of the condensation product above can also produce condensation products made from stearylamine, dimethylaniline or polymeric ethylene diamines be used. When using the product made of stearylamine, the feel of the goods is also improved.
