Description

Verfahren zum Färben von Gebilden aus Superpolyamiden oder -urethanen Gebilde aus Superpolyamiden, z. B. Fasern, Fäden; Garne, Gewerbe, Bändchen oder Bahnen, haben eine gute Affinität für die Farbstoffe, die man üblicherweise zum Färben von Wolle oder Seide verwendet, beispielsweise für saure Farbstoffe oder Beizenfarbstoffe. Man hat auch schon substantive, ühlicherweise zum Färben von Baumwolle oder umgefällter Cellulose verwendete Farbstoffe für den gleichen Zweck vorgeschlagen. Alle .diese Farbstoffe färben Gebilde aus Superpolyamiden in kräftigen und echten Tönen. Die Färbungen sind jedoch häufig nicht gleichmäßig.Process for dyeing structures made from superpolyamides or super-urethanes Structures made from super polyamides, e.g. B. fibers, threads; Yarn, commercial, ribbon or Orbits, have a good affinity for the dyes that are commonly used for Used for dyeing wool or silk, for example for acidic dyes or Mordant dyes. One already has substantive ones, usually for dyeing cotton or reprecipitated cellulose have proposed dyes used for the same purpose. All of these dyes color structures made of super polyamides in strong and genuine Tones. However, the colors are often not uniform.

Es wurde nun gefunden, daß man Gebilde aus Superpolyamiden oder -urethanen sehr gleichmäßig färben kann, wenn man sie mit wäßrigen neutralen Lösungen oder Suspensionen von sulfonsäuregruppenfreien Chromkomplexverbindungen von Azofarbstoffen, die mindestens eine Sulfonsäureamidgruppe enthalten, behandelt. Man erhält so Färbungen von besserer Wasser- und Waschechtheit als mit den bekannten entsprechenden, Sulfonsäuregruppen enthaltenden Farbstoffen aus saurem Bad.It has now been found that structures made from superpolyamides or super-urethanes can be used can be colored very evenly if you use neutral aqueous solutions or Suspensions of sulfonic acid group-free chromium complex compounds of azo dyes, which contain at least one sulfonic acid amide group, treated. This gives colorations of better water and wash fastness than with the known corresponding sulfonic acid groups containing dyes from acid baths.

Soweit die Löslichkeit ausreicht, können die sulfonsäureamidgruppenhaltigen Farbstoffe aus ihrer wäßrigen Lösung gefärbt werden. Im andern Fall verwendet man ihre feinverteilten Aufschlämmungen. Die Färbebäder können die üblichen Zusätze, wie Ammaniumchlorid oder Natriumsulfat, enthalten.As far as the solubility is sufficient, they can contain sulfonic acid amide groups Dyes can be colored from their aqueous solution. In the other case one uses their finely divided slurries. The dye baths can be the usual ones Additions, such as ammonium chloride or sodium sulfate.

Die sulfonsäureamidgruppenhaltigen Farbstoffe eignen sich zum Färben von Gebilden aus einheitlichen Superpolyamiden; die beispielsweise durch Kondensieren von (o, r)'-,Dicarbonsäuren mit (o, '-Diaminen, z. B. von tAdipinsäure mit Hexamethylendiamin, oder von o)-Aminocarbonsäuren, z. B. a-Aminocapronsäure, oder deren funktionellen Derivaten oder auch Mischungen dieser Stoffe miteinander hergestellt werden können. Gebilde aus Superpolyurethanen, die man durch Erhitzen von Diisocyanaten mit Glykolen erhalten kann, können ebenfalls damit gefärbt werden. Man kann aber auch Mischungen aus Superpolyamiden und -urethanen, sei es in Form von aus Mischkondensaten hergestellten Gebilden, sei es in Form von Gemischen fertiger Gebilde aus Superpolyamiden einerseits und Superpolyurethanen andererseits, nach der Erfindung färben. Ebenso eignet sich das Verfahren zum Färben von Mischungen der Gebilde aus Superpolyamiden oder -urethanen mit anderen organischen Faserstoffen, z. B. von Mischgeweben aus Superpolyamidfasern und Baumwolle oder Kunstseide aus regenerierter Cellulose. Beispiel i io g der komplexen Chromverbindung des Azofarbstoffes aus diazotiertem i-:Amino-2-oxybenzol-5-sulfonsäureamid und 2-Oxynaphthalin werden in So 1 heißem Wasser gelöst und ioo g Natriumsulfat hinzugefügt. In diesem Bad werden itooo@ g Superpplyamidfasern i Stunde lang bei Kochtemperatur gefärbt. Unter vollständiger Erschöpfung des Bades erhält man gleichmäßige Violettfärbungen von hervorragender Waschechtheit.The dyes containing sulfonic acid amide groups are suitable for dyeing of structures made of uniform superpolyamides; for example by condensing of (o, r) '-, dicarboxylic acids with (o,' -diamines, e.g. of tadipic acid with hexamethylenediamine, or of o) -amino carboxylic acids, e.g. B. a-aminocaproic acid, or their functional Derivatives or mixtures of these substances with one another can be produced. Structures of super-polyurethanes, which are obtained by heating diisocyanates with glycols can also be colored with it. But you can also mix it from super polyamides and urethanes, be it in the form of mixed condensates Formed, be it in the form of mixtures of finished structures made of superpolyamides on the one hand and super-polyurethanes on the other hand, color according to the invention. It is also suitable the process for dyeing mixtures of structures made from superpolyamides or super-urethanes with other organic fibers, e.g. B. of blended fabrics made of superpolyamide fibers and cotton or rayon made from regenerated cellulose. Example i io g of the complex Chromium compound of the azo dye from diazotized i-: Amino-2-oxybenzene-5-sulfonic acid amide and 2-oxynaphthalene are dissolved in so 1 hot water and 100 g of sodium sulfate added. In this bath itooo @ g superpplyamide fibers are added for one hour Colored cooking temperature. When the bath is completely exhausted, the result is uniform Violet dyeings of excellent wash fastness.

Mit der komplexen Chromverhindung des Azofarbstoffes aus diazotiertem i-Amino-2-oxybenzol-5-sulfonsäureamid und .i-Phenyl-3-methyl-5-pyrazolon erhält man orange Färbungen von ebenso guter Echtheit wie mit dem in Absatz i beschriebenen Farbstoff.With the complex chromium compound of the azo dye from diazotized i-Amino-2-oxybenzene-5-sulfonic acid amide and i-phenyl-3-methyl-5-pyrazolone are obtained one orange dyeings of just as good fastness as with that described in paragraph i Dye.

Beispiele 5 g der komplexen Chromverbindung des Azofarbstoffes aus diazotierter i-,Aminobenzol-2-carl)onsäüre und i-Phenyl-3-methyl-5-pyrazolon-3-sulfonsäureamid werden in der in Beispiel i beschriebenen Weise auf Superpolyamidfasern gefärbt. Man erhält gelbe Färbungen von hoher Wasser- und Waschechtheit.Examples 5 g of the complex chromium compound of the azo dye diazotized i-, aminobenzene-2-carl) onic acid and i-phenyl-3-methyl-5-pyrazolone-3-sulfonic acid amide are dyed in the manner described in Example i on superpolyamide fibers. Yellow dyeings of high water and wash fastness are obtained.

Färbungen mit gleichen Echtheiten erhält man mit der roten komplexen Chromverbindung des Azofarbstoffes aus diazotiertem i-Amino-2-oxynitrobenzol und i-Phenyl-3-methyl-5-pyrazolon-3'-sulfonsäureamid oder mit der orangen komplexen Chromverbindung des Azofartbstoffes aus diazotiertem i-Amino-2-oxy-5-nitrobenzol und i-Phenyl-3-methyl-5-pyrazolon-3'-sulfonsäureamid.Dyeings with the same fastness properties are obtained with the red complex Chromium compound of the azo dye from diazotized i-amino-2-oxynitrobenzene and i-Phenyl-3-methyl-5-pyrazolone-3'-sulfonic acid amide or with the orange complex Chromium compound of the azo dye from diazotized i-amino-2-oxy-5-nitrobenzene and i-phenyl-3-methyl-5-pyrazolone-3'-sulfonic acid amide.
