Description

Verfahren zum Färben von Celluloseestern und -äthern Es wurde gefunden, daß man Celluloseester und -äther für sich oder im Gemisch mit anderen Fasern pflanzlichen oder tierischen Ursprungs oder mit Fasern aus umgefällter Cellulose aus neutralem Salzbade in vorteilhafter Weise färben kann, wenn man: als Farbstoffe wasserlösliche Salze von i-Aminoq. - phaaiylaminoanthrachinon - 2 - carbonsäuren unter dem üblichen Zusatz neutraler Salze, wie Natriumsulfat, verwendet.Process for dyeing cellulose esters and ethers It has been found that one cellulose esters and ethers alone or in a mixture with other vegetable fibers or of animal origin or with fibers from reprecipitated cellulose from neutral Salt baths can be colored in an advantageous manner if: the dyes are water-soluble Salts of i-Aminoq. - phaaiylaminoanthraquinone - 2 - carboxylic acids below the usual Addition of neutral salts, such as sodium sulfate, used.

Es können z. B. Natrium- oder Ammoniumsalze der genannten Farbstoffe oder ihre Salze mit organischen Basen verwendet werden.It can e.g. B. sodium or ammonium salts of the dyes mentioned or their salts with organic bases can be used.

Man hat zwar schon vorgeschlagen, zum Färben von Acetatkunstseide Anthrachinonabkömmlinge mit Sulfonsäuregruppen oder nicht kerngebundenen Carboxylgruppen zu verwenden. Erstere besitzen jedoch nur ungenügende Naßechtheiten und zeigen beim. Färben von Mischgeweben die unangenehme Erscheinung des Wanderns. Die Farbstoffe mit nicht kerngebundener Carboxylgruppe haben häufig :ein ungenügendes Aufziehvermögan und sind mitunter auch unbeständig- Die bei dem vorliegenden Verfahren zu verwendenden Farbstoffe haben dagegen durchweg gutes Naßechtheiten und :ein sehr gutes Aufziehvermögen. Dank ihrer Wasserlöslichkeit können. sie zur Herstellung starker FärbIebäder benutzt werden und gestatten :ein gleichmäßiges Durchfärben Glicht geschlagener Acetatkuns:tseidengewehe. Man hat schließlich auch schon daran gedacht, u. a. i-Amino-2-brom-4.-phemylamimoanthrachin.on-6-.carbonsäure zum Färben von Acetatkunstseide heranztuiehen, doch erhält .man dabei färberisch unbefriedigende, schwache Töne, die dem Vorschlag keinen Eingang in die Technik verschafft haben.. Beispiel Man behandelt i o Teile Acetatkuns.tseide i Stunde lang bei :etwa 7o'@. in einem Bad, das in 3oo Teilen Wasser p, i Teil .des Ammoniumsalzes der r-Amino-q. @ph:enylaminoanthrachinon-2-carbo:nsäure (hergestellt durch Bromieren von i-Amin:oanthrachinon-2-carbonsäure und Umsetzen der so erhaltenen i - Amino-q.-hromanthrachinon - 2-carbonsäure mit Anilin) und 5 Teile Natriumsulfat .ent- hält. Man erhält so eine echte, grünstichig- blaue Färbung. In entsprechender Weise liefern Salze der i -Amino - q. - (p - aminophenyl) -aminoanthra- chinon-z-@carbonsäure (hergestellt durch Um- setzen von i-Amin:o-q.-b@romanthrachinon-z-car- bonsäure mit i, ¢-Diaminobenzol) grüne Fär- bungen. It has already been proposed to use anthraquinone derivatives with sulfonic acid groups or non-core-bonded carboxyl groups for dyeing acetate rayon. However, the former have insufficient wet fastness properties and show at. Dyeing mixed fabrics the unpleasant appearance of hiking. The dyes with a carboxyl group not bonded to the nucleus often have: an insufficient absorption capacity and are sometimes also unstable- The dyes to be used in the present process, on the other hand, consistently have good wet fastness properties and: a very good absorption capacity. Thanks to their solubility in water you can. They are used for the production of strong dye baths and allow: a uniform dyeing of the light of beaten acetate art: silk threads. Finally, one has already thought of using i-amino-2-bromo-4-phemylamimoanthraquinone-6-carboxylic acid for dyeing acetate rayon, but weak tones which are unsatisfactory in terms of dyeing are not accepted into technology .. Example One treats 10 parts of acetate silk for 1 hour at: about 7o '@. in a bath which, in 300 parts of water, p, i part of the ammonium salt of the r-amino-q. @ph: enylaminoanthraquinone-2-carbonic acid (produced by brominating i-amine: oanthraquinone-2-carboxylic acid and reacting the i-amino-q.-hromanthraquinone-2-carboxylic acid obtained in this way with aniline) and 5 parts of sodium sulfate. holds. You get a real, green-tinged blue coloring. In a corresponding manner, salts provide the i -Amino - q. - (p - aminophenyl) -aminoanthra- quinone-z- @ carboxylic acid (produced by setting of i-amine: oq.-b@romanthrachinon-z-car- acid with i, ¢ -diaminobenzene) green coloring exercises.
