Description

Verfahren zum Färben von künstlicher Seide aus Celluloseestern bzw. -äthern und ihren Umwandlungsprodukten. Es wurde gefunden, daß zu den Farbstoffen mit großer Affinität zur Acetatseidenfaser und ähnlichen Kunststoffen auch die i-Aniinoanthrachinon-2-sulfosäure und ihre Substitutionsprodukte gehören. Man erhält mit diesen Farbstoffen tiefe, klare Färbungen mit ausgezeichneten Echtheitseigenschaften. Beispiel i.Process for dyeing artificial silk from cellulose esters or ethers and their conversion products. It was found that to the dyes i-Aniinoanthraquinone-2-sulfonic acid also has a great affinity for acetate silk fibers and similar plastics and their substitution products belong. With these dyes one obtains deep, clear dyeings with excellent fastness properties. Example i.

o,6 Gewichtsteile r - Aminoanthracliinon-2-sulfOS:itire werden in einem Liter Wasser heiß gelöst. plan färbt im Flottenverhiltnis r : 2o mit oder ohne Zusatz von Salzen bei 7o° während I,, Stunde. Der Farbstoff zieht auf Acetatseide in klaren, orangen Tönen.0.6 parts by weight r - Aminoanthracliinon-2-sulfOS: itire are in one liter of hot water. plan colors in the liquor ratio r: 2o with or without addition of salts at 70 ° for 1 1/2 hours. The dye draws on acetate silk in clear, orange tones.

Beispiel e.Example e.

o,6 Gewichtsteile r-Arnino-4.-bromanthrachinon-2-stilfosätiFe werden in einem Liter Wasser heiß gelöst. Die weitere Aufarbeitung erfolgt, wie dies im Beispiel i angegeben ist. Man erhält auf Acetatseide ein klares Gelbrot. Beispiel 3. 0.6 parts by weight of r-arnino-4.-bromoanthraquinone-2-stilfosätiFe are dissolved in one liter of hot water. The further work-up takes place as indicated in example i. A clear yellow-red is obtained on acetate silk. Example 3.

o,6 Gewichtsteile r-Amino-4.-thiotolylanthracliinon-2-sulfosäure werden gemäß den Angaben von Beispiel r und 2 gefärbt. Man erhält so auf Acetätseide schöne und klare rotviolette Töne.0.6 parts by weight of r-amino-4.-thiotolylanthracliinon-2-sulfonic acid colored according to the instructions of example r and 2. In this way you get beautiful ones on acetate silk and clear red-violet tones.

Beispiel q..Example q ..

o,6 Gewichtsteile i-Amino-5-p-toluidoatithrachinon-2-sulfosäure werden, wie vorstehend geschildert, auf Acetatseide gefärbt. Die Faser wird hierbei bordeaux angefärbt.0.6 parts by weight of i-amino-5-p-toluidoatithraquinone-2-sulfonic acid, dyed as described above on acetate silk. The fiber becomes burgundy stained.
