Description
Verfahren zur Herstellung gefärbter künstlicher Gebilde Es ist bekannt, daß man gefärbte künstliche Gebilde, wie Fäden, Fasern, Bänder oder Folien, herstellen kann, wenn man den zu verformenden Massen geeignete Farbstoffe, auch Azofarbstoffe, zusetzt. Derartige zu verformende Massen sind z. B. Cellulose als Viskoselösung oder als Lösung in Kupferoxyd-Ammoniak, Celluloseester, Polyamide, Polyurethane, Polyacrylnitril. Nach den zu färbenden Massen richtet es sich, ob die Farbstoffe in suspendierter oder gelöster Form bzw. ohne besonderen Zusatz den Spinnmassen zugegeben werden. Process for the production of colored artificial structures It is known that colored artificial structures such as threads, fibers, ribbons or foils are produced can, if the masses to be shaped suitable dyes, including azo dyes, clogs. Such masses to be deformed are z. B. cellulose as a viscose solution or as a solution in copper oxide-ammonia, cellulose esters, polyamides, polyurethanes, Polyacrylonitrile. It depends on the masses to be colored whether the dyes in suspended or dissolved form or without any special addition to the spinning masses be admitted.
Es wurde nun gefunden, daß sich zur Herstellung von gefärbten künstlichen Gebilden Azofarbstoffe besonders eignen, die der folgenden allgemeinen Formel entsprechen: worin R einen von Sulfonsäure- und Carbonsäuregruppen freien aromatischen Rest bedeutet und n für 1 oder2 steht.It has now been found that azo dyes which correspond to the following general formula are particularly suitable for the production of colored artificial structures: where R is an aromatic radical free of sulfonic acid and carboxylic acid groups and n is 1 or 2.
Die mit diesen Farbstoffen in der Masse gefärbten künstlichen Gebilde zeichnen sich durch eine besonders klare und leuchtende Nuance aus. The artificial structures colored in the mass with these dyes are characterized by a particularly clear and luminous shade.
Beispiel 1 In 1,3 kg Viskose mit 7,70/o Cellulose werden 15 g Farbpaste eingerührt. Diese besteht aus 3001o des Disazofarbstoffs Dianisidin , Naphthohydrochinonmethylensulfonäther (4'-Oxy-naphtho-[2', 1': 4, 5]-oxathiol-S-dioxyd), 30 ovo Kondensationsprodukt aus Oxydiphenyl, Benzylchlorid und Äthylenoxyd gemäß Patentschrift 824 949, 40 °/0 Wasser und wird in einem geeigneten Knetapparat hergestellt. Nach dem Verspinnen erhält man eine leuchtend blaugefärbte Zellwolle. Die Färbung besitzt sehr gute Echtheiten. EXAMPLE 1 15 g of color paste are added to 1.3 kg of viscose with 7.70 / o cellulose stirred in. This consists of 3001o of the disazo dye dianisidine, naphthohydroquinone methylene sulfone ether (4'-Oxy-naphtho- [2 ', 1': 4, 5] -oxathiol-S-dioxide), 30 ovo condensation product from Oxydiphenyl, benzyl chloride and ethylene oxide according to patent specification 824 949, 40% water and is made in a suitable kneading machine. Receives after spinning a bright blue colored rayon. The dyeing has very good fastness properties.
Beispiel 2 Der Azofarbstoff aus l-Amino-2-methoxy-4-benzoylamino-5-methylbenzol und Naphthohydrochinonmethylensulfonäther wird unter Zusatz des Kondensationsproduktes aus Naphthalinsulfonsäure und Formaldehyd und Wasser in einer Kugelmühle dispergiert. Man setzt die so hergestellte Dispersion einer Lösung von Cellulose in Kupferoxyd-Ammoniak zu, so daß die Cellulose nach der Ausspinnung 20/, Farbstoff enthält. Die Färbung ist ein klares Violett mit sehr guten Echtheitseigenschaften. Example 2 The azo dye from 1-amino-2-methoxy-4-benzoylamino-5-methylbenzene and naphthohydroquinone methylene sulfonic ether is added with the addition of the condensation product from naphthalenesulfonic acid and formaldehyde and water dispersed in a ball mill. The dispersion thus prepared is a solution of cellulose in copper oxide-ammonia to, so that the cellulose contains 20 /, dye after spinning. The coloring is a clear purple with very good fastness properties.
Beispiel 3 In eine Lösung, die 500 g Polyacrylnitril enthält, wird eine Farbpaste aus 30 Gewichtsteilen Kondensationsprodukt wie im Beispiel 1, 40 Gewichtsteilen Dimethylformamid und 30 Gewichtsteilen des Disazofarbstoffs Dianisidin , Naphthohydrochinonmethylensulfonäther eingerührt. Nach dem Verspinnen erhält man eine Polyacrylnitrilfaser von sehr klarer, blauer Nuance. Example 3 In a solution containing 500 g of polyacrylonitrile is a color paste of 30 parts by weight of condensation product as in Example 1, 40 Parts by weight of dimethylformamide and 30 parts by weight of the disazo dye dianisidine , Stirred in naphthohydroquinone methylene sulfone ether. After spinning you get a polyacrylonitrile fiber with a very clear, blue shade.
