Description

Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zur Herstellung lichtechter Färbungen auf Kunstseide aus regenerierter Cellulose, die unter Verwendung von Titandioxyd spinnmattiert worden ist, mit Substantiven Farbstoffen nach Patent6i8329· Nach dem in diesem Patent beschriebenen Verfahren wird spinnmattierte Kunstseide aus regenerierter Cellulose zum Färben verwendet, die nach dem Mattieren oder vor dem Färben mit wasserlöslichen Chromverbindungen behandelt worden ist.The invention relates to a further embodiment of the method for producing lightfast Dyes on rayon made from regenerated cellulose, which has been spin-matted using titanium dioxide, with Nouns dyes according to patent6i8329 The process described in this patent is used to produce spun-matt rayon Made from regenerated cellulose used for dyeing after matting or before dyeing has been treated with water-soluble chromium compounds.

Es wurde nun gefunden, daß dieses Verfahren in der Weise abgeändert werden kann, daß die spinnmattierte Kunstseide ohne Vorbehandlung gefärbt und nach dem Färben einer Behandlung mit wasserlöslichen chromhaltigen Verbindungen unterworfen wird. Auch in diesem Falle werden Färbungen erhalten, die im trockenen und im feuchten Zustande lichtecht sind.It has now been found that this procedure can be modified in such a way that that the spun-matted rayon is dyed without pretreatment and after dyeing is subjected to a treatment with water-soluble chromium-containing compounds. In this case, too, dyeings are obtained which are dry and wet are lightfast.

Die Erfindung ist auf die folgenden Ausführungsbeispiele nicht beschränkt. Die Teile sind Gewichtsteile.The invention is not restricted to the following exemplary embodiments. the Parts are parts by weight.

Beispiel ιExample ι

Kunstseide aus regenerierter Cellulose, die durch Zusatz von Titandioxyd zur Spinnmasse mattiert und mit Chlorazol Orange PO (Schultz, Farbstofftabellen, 7. Auflage, Nr. 747) gefärbt worden ist, wird Y2 Stunde lang bei 85 ° C in einer Lösung nachbehandelt, die 21Z2 Teile Kaliumbichromat und 2Y2TeUe Ameisensäure auf 10 000 Teile Wasser enthält. Rayon made from regenerated cellulose, which has been matted by adding titanium dioxide to the spinning mass and dyed with Chlorazole Orange PO (Schultz, Dye Tables, 7th Edition, No. 747), Y is post-treated for 2 hours at 85 ° C in a solution which 2 1 Z contains 2 parts of potassium dichromate and 2Y 2 parts of formic acid per 10,000 parts of water.

Beispiel 2Example 2

Die in der im Beispiel 1 beschriebenen Weise gefärbte Kunstseide wird 1J2 Stunde lang bei 85 ° C in einer Lösung umgezogen, die 21Z2 Teile Chromfluorid auf 10 000 Teile Wasser enthält.The artificial silk dyed in the manner described in Example 1 is drawn for 1 J 2 hours at 85 ° C. in a solution which contains 2 1 Z 2 parts of chromium fluoride per 10,000 parts of water.
