Description
Verfahren zum Färben von Celluloseestern. Es wurde gefunden, daß die Glycine, x#,-elche durch Einwirkung von Halolgenessigsauren auf unsulfierte aromatische Basen oder basische Farbstoffe mit freier Aminogruppe entstehen, und besonders deren in Wasser leicht löslichen Salze auf Acetylcellulose teils ungefärbt, teils gefärbt direkt kräftig aufziehen. Die so auf die Faser gebrachten Produkte lassen sich überraschenderweise auch diazotieren und mit Aminen, Phenolen und Aminophenolen entwickeln.Process for dyeing cellulose esters. It has been found that the glycines, x #, - elche are formed by the action of haloacetic acids on unsulfated aromatic bases or basic dyes with free amino groups, and especially their easily water-soluble salts are directly absorbed onto acetyl cellulose, partly uncolored and partly colored. The products applied to the fiber in this way can, surprisingly, also be diazotized and developed with amines, phenols and aminophenols.
Der Vorteil der Anwendung der Glycine gegenüber den Aminen liegt vor allem in der leichten Löslichkeit der ersteren, die die Anwendbarkeit dieser Produkte für das Färben von Acetatseide gegenüber den teilweise schwer löslichen Aminen stark vereinfacht.The advantage of using the glycines over the amines is present mainly in the easy solubility of the former, which makes the applicability of these products strong for dyeing acetate silk compared to the sometimes sparingly soluble amines simplified.
Beispiele. i. i kg Acetatseide wird in einem Färbebade von 2o bis :25 1, in welchem 40 g des Glycins des a-Naphthylamins gelöst sind, mit oder ohne Zusatz von Salzen oder Säuren ohne oder mit Schutzkolloiden % bis i Stunde bei 6o bis 70' C umgezogen, darauf wird gespült, wie üblich in einem frischen Bade diazotiert und in einem weiteren Bade mit ß-Oxynapht-hoesäure bei 5o' C schwach essigsauer entwickelt. Nach dem Färben wird geseift und aviviert. Man erhält ein Violettschwarz von guter Echtheit. :2. 1 kg Acetatseide wird in einem Färbebade von 2-o bis 25 1, in welchem 30 g des Glycins aus Aminoazobenzol gelöst sind, mit oder ohne Zusatz von Salzen oder Säuren ohne oder mit Schutzkolloiden % bis i Stunde bei 6o bis 70' C gefärbt. Man erhält auf der Faser ein kräftiges Gelb.Examples. i. i kg acetate rayon is in a Färbebade of 2o by moved g 25 1, in which 40 of the glycine of the a-naphthylamine are dissolved, with or without addition of salts or acids without or with protective colloids% to i hour at 6o to 70 'C. Then it is rinsed, diazotized as usual in a fresh bath and developed in a further bath with ß-oxynaphthoic acid at 50 ° C. weakly acetic acid. After dyeing, it is soaped and finished. A violet-black of good fastness is obtained. : 2. 1 kg acetate silk is dissolved in a Färbebade of 2-o to 25 1, in which 30 g of glycine from aminoazobenzene, stained with or without addition of salts or acids without or with protective colloids% to i hour at 6o to 70 'C. A strong yellow is obtained on the fiber.
3. 1 kg Acetatseide wird in einem Färbebade von 2o bis 25 1, in welchem 2o g des Glycins aus i , 4-Diaminoanthrachinon gelöst sind, mit oder ohne Zusatz von Salzen oder Säuren ohne oder mit Schutzkolloiden % bis i Stunde bei 6o bis 70' C gefärbt. Man erhält auf der Faser ein kräftiges Violett von vorzüglicher Echtheit. Ersetzt man das Glycin des i - 4-Diarninoanthrachinons durch das Glycin des I - 4 - 5 - 8-Tetraaminoanthrachinons, so erhält man ein tiefes Blau, bei Verwendung des Glycins aus i -Amino-4-oxvanthrachinon ein kräftiges Rotviolett. 3. 1 kg acetate rayon is in a Färbebade from 2o to 25 1, in which 2o g of glycine from i, 4-diaminoanthraquinone are dissolved, with or without addition of salts or acids without or with protective colloids% to i hour at 6o to 70 'C colored. A strong violet of excellent fastness is obtained on the fiber. By replacing the glycine of the i - 4-Diarninoanthrachinons by the glycine of I - 4 - 5 - 8-Tetraaminoanthrachinons, so when using one obtains a deep blue, the glycine from i-amino-4-oxvanthrachinon a strong red-violet.
