Description

Verfahren zum Färben von künstlicher Seide aus Acidylcellulosen, Celluloseäthern und ihren Umwandlungsprodukten Es wurde die überraschende Beobachtung gemacht, daß Farbstoffe aus Diazoverbindungen von Aminomonosulfosäuren und Aminomonocarbonsäuren und ihren Substitutionsprodukten, gekuppelt mit a, y-Diketohydrinden und seinen Derivaten, starke Verwandtschaft zu Acetatseide oder Seide ausCelluloseäthern besitzen. Man erhält mit ihrer Hilfe sehr reine und echte Färbungen. Die Farbstoffe sind besonders deswegen wertvoll, weil sie in Mischung mit anderen Farbstoffen für Acetatseide oder Seide aus Celluloseäthern nicht die Erscheinung der Phototropie zeigen. Beispiel 30g des Ammoniumsalzes des Farbstoffs Anilin-¢-sulfosäure-azo-a, y-diketohydrinden werden in einem Liter Wasser heiß gelöst. Man färbt im Flottenverhältnis r :3o bis r :.4o mit oder ohne Zusatz von Salzen, schwachen Säuren oder schwachen Alkalien bei 7o° während '/,Stunden. Der schöne reingelbe Farbstoff zeigt auf Acetatseide sehr gute Echtheitseigenschaften.Process for dyeing artificial silk from acidyl celluloses, cellulose ethers and their conversion products The surprising observation was made that dyes made from diazo compounds of aminomonosulfonic acids and aminomonocarboxylic acids and their substitution products, coupled with α, γ-diketohydrinden and its derivatives, are closely related to acetate silk or silk own. With their help you get very pure and real colorations. The dyes are particularly valuable because they do not show the appearance of phototropy when mixed with other dyes for acetate silk or silk made from cellulose ethers. Example 30 g of the ammonium salt of the dye aniline -sulfonic acid-azo-α, γ-diketohydrind are dissolved in one liter of hot water. The dyeing is carried out in a liquor ratio of r: 30 to r: 40 with or without the addition of salts, weak acids or weak alkalis at 70 ° for 1/2 hours. The beautiful, pure yellow dye shows very good fastness properties on acetate silk.
