Description

Verfahren zum Färben von künstlicher Seide aus Acidylcellulosen, Celluloseäthern oder ihren Umwandlungsprodukten. Weitaus die größte Zahl der Monoazofarbstoffe hat keine Verwandtschaft zur Acotatseidenfaser.Process for dyeing artificial silk from acidyl celluloses, cellulose ethers or their conversion products. Has by far the largest number of monoazo dyes no relationship to acotate silk fiber.

Es wurde nun gefunden, daß überraschenderweise Farbstoffe aus Diazoverbindungen von Aminen oder ihren Substitutionsprodukten gekuppelt mit Alkylarall,-ylanilinsulfosäurer oder ihren Substitutionsprodukten starke Verwandtschaft zur Acetatseide oder Seiden aus Celluloseäthern haben. Man erhält mit ihrer Hilfe schöne gelbe bis rotviolette Färbungen mit ausgezeichneten Echtheitseigenschaften.It has now been found that, surprisingly, dyes made from diazo compounds of amines or their substitution products coupled with alkylarall, -ylaniline sulfonic acid or their substitute products are strongly related to acetate silk or silk from cellulose ethers. With their help, beautiful yellow to red-violet ones are obtained Dyeings with excellent fastness properties.

Beispiel i.Example i.

2 g des Farbstoffs aus 6-Nitro-2-toluidin und N-metliyl-N-benzylanilinsulfosaurem Natrium werden in 11 Wasser heiß gelöst. Man färbt im Flottenverhältnis i :2o bis i : 4o mit oder ohne Zusatz von Salzen bei etwa 70° während dreiviertel Stunden. Der schöne klargelbe Farbstoff zeigt auf Acetatseide sehr gute Echtheitseigenschaften. Beispiel 2.2 g of the dye of 6-nitro-2-toluidine and N-metliyl-N-benzylanilinsulfosaurem sodium are dissolved hot in 1 1 water. The dyeing is carried out in a liquor ratio of i: 2o to i: 4o, with or without the addition of salts, at about 70 ° for three quarters of an hour. The beautiful, clear yellow dye shows very good fastness properties on acetate silk. Example 2.

Der Farbstoff aus a-Naphthylamin und äthylbenzylanilinsulfosaurem Natrium wird in gleicher Weise wie i gefärbt. Erzieht auf die Acetatseide in orangeroten Tönen auf.The dye from a-naphthylamine and äthylbenzylanilinsulfosaurem Sodium is colored in the same way as i. Educates on the acetate silk in orange-red Tones on.

Beispiel 3.Example 3.

Der Farbstoff aus 2 # 4-Dinitr-oanilin und methylbenzylanilinsulfosaurem Natrium wird wie i und 2 gefärbt. Er zieht in stark blaustichig roter Nuance auf die Acetatseidenfaser und zeigt sehr gute Echtheitseigenschaften.The dye from 2 # 4-Dinitr-oanilin and methylbenzylanilinsulfosaurem Sodium is colored like i and 2. It pulls on in a strong bluish red shade the acetate silk fiber and shows very good fastness properties.
