Description
DEUTSCHESGERMAN
Es wurde gefunden, daß, wenn man synthetische Fasermaterialien, die im wesentlichen aus Polyestern bestehen, mit l,4-Diamino-2-nitro-anthrachinon färbt, Färbungen guter Lichtechtheit erhalten werden. Dieses ist überraschend, weil l,4-Diamino-2-nitro-anthrachinon in Gegensatz zu Farbstoffen ähnlicher Konstitution, wie 1,4-Diamino-2-methoxy-, l,4-Diamino-5-nitro- und 1,4-Diamino-2,3-dichlor-anthrachinon, als Farbstoff für Celluloseacetat wegen seiner schlechten Lichtechtheit nicht in Frage kommt. It has been found that when using synthetic fiber materials consisting essentially of polyesters, dyes with 1,4-diamino-2-nitro-anthraquinone, dyeings of good lightfastness are obtained. This is surprising because 1,4-diamino-2-nitro-anthraquinone in contrast to dyes of a similar constitution, such as 1,4-diamino-2-methoxy-, 1,4-diamino-5-nitro- and 1,4-diamino-2,3-dichloro-anthraquinone, as a dye for cellulose acetate is out of the question because of its poor lightfastness.
Die Durchführung der Ausfärbung kann nach den Methoden erfolgen, die üblicherweise für das Färben von Polyesterfasermaterialien verwendet werden. Man kann die Ausfärbung also z. B. bei Kochtemperatur vornehmen, vorzugsweise in Gegenwart der üblicherweise verwendeten »Carrier«, wie Benzoesäure, Salicylsäure, Kresotinsäuremethylester, o- bzw. p-Oxydiphenyl oder Trichlorbenzol, oder aber man kann die Ausfärbungen auch bei erhöhter Temperatur unter Druck durchführen.The coloration can be carried out by the methods customarily used for dyeing of polyester fiber materials can be used. You can change the color z. B. at cooking temperature, preferably in the presence of the commonly used "carriers" such as benzoic acid, salicylic acid, Cresotinic acid methyl ester, o- or p-oxydiphenyl or Trichlorobenzene, or the coloration can also be carried out at elevated temperature under pressure.
Die Herstellung des l,4-Diamino-2-nitro-anthrachinon kann nach bekannten Verfahren erfolgen, wie sie z. B. in den deutschen Patentschriften 254 185 und 267 445 beschrieben werden. Die Farbstoffe werden vorteilhafterweise in einem feinen Verteilungszustand verwendet. Dieser feine Verteilungszustand kann nach einer der üblichen Methoden erreicht werden, z. B. durch Verpasten aus Schwefelsäure und durch Vermählen mit Dispergiermitteln. The preparation of the 1,4-diamino-2-nitro-anthraquinone can be carried out by known processes, such as those described, for. B. in German patents 254 185 and 267 445 are described. The dyes are advantageous used in a fine distribution state. This fine distribution state can be according to one of the common methods can be achieved, e.g. B. by pasting from sulfuric acid and by grinding with dispersants.
1 kg Polyesterfasern, z. B. Polyäthylenglycolterephthalat, wird in einer Flotte von 20 bis 401 Wasser mit einer Suspension von 10 g l^-Diamino^-nitro-anthrachinon, das man vorteilhafterweise, z. B. durch Verpasten Färben von Polyesterfasermaterialien1 kg of polyester fibers, e.g. B. polyethylene glycol terephthalate is in a liquor of 20 to 401 of water a suspension of 10 g l ^ -diamino ^ -nitro-anthraquinone, that one advantageously, z. B. by paste dyeing of polyester fiber materials

aus Schwefelsäure und durch Vermählen mit Dispergiermitteln, vorher in feine Verteilung gebracht hat, 2 Stunden bei 125° C unter Druck gefärbt. Man erhält eine kräftige blaugrüne Färbung von sehr guten Echtheiten. Färbt man bei 95 bis 100° C und setzt dem Färbebad einen »Carrier« zu, z. B. 500 g Benzoesäure, 100 g o- bzw. p-Oxydiphenyl, 100 g Trichlorbenzol oder 100 g Kresotinsäuremethylester, gegebenenfalls in emulgierter Form, so erhält man eine ähnliche Färbung.from sulfuric acid and by grinding with dispersants, has previously brought into fine distribution, dyed under pressure at 125 ° C for 2 hours. You get a strong one blue-green coloring of very good fastness properties. The dyeing is carried out at 95 to 100 ° C and the dyebath is used »Carrier« to, z. B. 500 g benzoic acid, 100 g o- or p-oxydiphenyl, 100 g of trichlorobenzene or 100 g of methyl cresotinate, optionally in emulsified form, see above a similar color is obtained.
