Description
Verfahren zum Färben von Mischungen aus tierischen Fasern und natürlichen oder künstlichen Cellulosefasern Es wurde gefunden, daß man wertvolle Färbungen von guten Echtheitseigenschaften auf Mischungen von tierischen Fasern mit natürlichen oder künstlichen Cellulosefasern erhalten kann, wenn man Disazofarbstöffe von der Zusammensetzung A-N = N-B-N = N-C, worin A den Resteines Aminooxynaphthalins, dessen Hydroxylgruppe nicht in Orthostellung zur Azogruppe steht, B den Rest eines in Parastellung zur Aminogruppe gekuppelten oxygruppenfreien Amins der Benzol- oder Naphthalinreihe, C den Rest der auf die Naphthalseite gekuppelten 2-(4-Oxy-3'-carboxyphenylamino)- 5 - oxvnaphtlhalin - 7 -sulfonsäure bedeutet, wobei die Farbstoffkomponenten so zu wählen sind, daß der fertige Farbstoff mindestens zwei löslich machende Gruppen enthält, auf die Faser aufbringt und die erhaltenen Färbungen mit Metallsalzen behandelt. Die erhaltenen violetten, blauen und schwarzblauen Färbungen zeichnen sich durch gute Echtheitseigenschaften, insbesondere durch gute Lichtechtheit und gute Naßechtheiten, aus, ferner dadurch, daß die verschiedenen Fasern im Farbton untereinander gut übereinstimmen. Sie sind in diesen Eigenschaften den in bekannter Weise auf gleichen Fasergemischen hergestellten Färbungen mit metallkomplexbildenden Azofarbstoffen überlegen.Process for dyeing mixtures of animal fibers and natural or artificial cellulose fibers It has been found that valuable dyeings can be obtained of good fastness properties on mixtures of animal fibers with natural ones or artificial cellulose fibers can be obtained by using disazo dyes from the Composition A-N = N-B-N = N-C, where A is the residue of an aminooxynaphthalene, its The hydroxyl group is not in the ortho position to the azo group, B the remainder of a in the para position oxy-group-free amines of the benzene or naphthalene series coupled to the amino group, C the remainder of the 2- (4-oxy-3'-carboxyphenylamino) - coupled to the naphthalene side 5 - oxvnaphtlhalin - 7 -sulfonic acid means, the dye components so should be chosen that the finished dye has at least two solubilizing groups contains, applies to the fiber and the dyeings obtained are treated with metal salts. The violet, blue and black-blue colorations obtained are distinguished good fastness properties, in particular due to good light fastness and good wet fastness, from, furthermore by the fact that the different fibers match well with one another in color. In terms of these properties, they are based on the same fiber mixtures in a known manner produced dyeings with metal complex-forming azo dyes are superior.
Für die Metallsalzbehandlungkommen Salze des Aluminiums, Kupfers, Kobalts, Nickels, Chroms, Mangans und Mischungen dieser Salze in Betracht.For the metal salt treatment, salts of aluminum, copper, Cobalts, nickel, chromium, manganese and mixtures of these salts.
Beispiel I I kg eines Mischgarnes aus I Teil Wolle und I Teil Zellwolle aus Viscose wird in einem Bade behandelt, das 2o g des Farbstoffes I-Amino-7-oxynaphthalin-3-sulfonsäure# I-Amino-2, 5-dimethoxybenzol # 2-. (3'-Oxy -4 -carboxyphenylamino)-5-oxynaphthalin -7-sulfonsäure und 5oo g Natriumsulfat in 3oooo ccm Wasser enthält.Example I I kg of a mixed yarn made of I part wool and I part viscose wool Viscose is treated in a bath containing 2o g of the dye I-amino-7-oxynaphthalene-3-sulfonic acid # I-amino-2,5-dimethoxybenzene # 2-. (3'-Oxy -4-carboxyphenylamino) -5-oxynaphthalene -7-sulfonic acid and contains 500 g of sodium sulfate in 30000 cc of water.
Man geht in das lauwarme Bad ein, treibt auf Siedetemperatur, fügt 6 g der Kondensationsverbindung aus Octoclecylalkohol und 2o Mol Äthylenoxyd, 3o g Ammonsulfat und Iog Eisessig hinzu, behandelt ¾ Stunden bei Siedetemperatur, ¾ Stunden bei absinkender Temperatur, spült und behandelt I Stunde bei 9o° C in einem Bade, das I7,5 g Kupfersulfat. 2o g Chromacetat und Io g Eisessig auf 3o ooo ccm enthält, spült und trocknet.You go into the lukewarm bath, drive to the boiling point, add 6 g of the condensation compound of octoclecyl alcohol and 2o mol of ethylene oxide, 3o g ammonium sulphate and Iog glacial acetic acid are added, treated for ¾ hours at boiling temperature, ¾ Hours at a falling temperature, rinses and treats for 1 hour at 90 ° C in one Bath, the 17.5 g of copper sulfate. 20 g chromium acetate and 10 g glacial acetic acid to 30,000 cc contains, rinses and dries.
Man erhält eilt Mittelblau von sehr guter Lichtechtheit und guter Wasch- und Schweißechtheit.Medium blue of very good and good lightfastness is obtained Wash and perspiration fastness.
Beispiel e I kg eines Mischgewebes aus gleichen Teilen Wolle und Zellwolle aus Viscose wird in einem Bade behandelt, das 2og des Farbstoffes I - Amino-8-oxynaphthalin-3, 6-disulfonsäure # I-Amnino-2-methoxy-5-methylbenzol # 2-(3'-Oxy-4'-carboxyphenylamino)-5-oxynaphthalin-7-sulfonsäure, 5oo g Natriumtnsulfat in 3oooo ccm Wasser enthält.Example e I kg of a mixed fabric made from equal parts of wool and rayon from viscose is treated in a bath containing 2og of the dye I - amino-8-oxynaphthalene-3, 6-disulfonic acid # I-Amnino-2-methoxy-5-methylbenzene # 2- (3'-Oxy-4'-carboxyphenylamino) -5-oxynaphthalene-7-sulfonic acid, Contains 5oo g of sodium sulfate in 3,000 ccm of water.
Man geht lauwarm ein, treibt auf Siedetemperatur, fügt 6 g der Kondensationsverbindung aus 2o Mol Äthylenoxyd und Octodecylallkohol, 3o g Ammonsulfat sowie Io g Eisessig hinzu, behandelt ¾ Stunden bei Siedetemperatur, s¾4 Stunden bei absteigender Temperatur, spült und behandelt I Stunde hei 9o° C mit I7,5 g Kupfersulfat. 2o g Chromacetat und Io g Eisessig in 30 000 ccm Wasser nach, spült und trocknet. Man erhält ein Mittelblau von sehr guten Echthetseigenschaften.It is lukewarm, driven to boiling temperature, 6 g of the condensation compound are added from 20 moles of ethylene oxide and octodecyl alcohol, 3o g of ammonium sulfate and 10 g of glacial acetic acid added, treated ¾ hours at boiling temperature, s¾4 hours at decreasing temperature, rinsed and treated for 1 hour at 90 ° C. with 17.5 g of copper sulfate. 20 g chromium acetate and 10 g of glacial acetic acid in 30,000 cc of water, rinses and dries. One receives a Medium blue with very good real properties.
