Description

Verfahren zum Färben von Celluloseestern Es wurde gefunden, daß man. in einfacher Weise feste Celluloseester, insbesondere Acetatseide, färben kann, wenn man diese mit nicht acidylierten Aminoanthrachinonen oder ihren Substitutionspro:dukten, die einen schwach basischen Charakter besitzen und natürliche Fasern nicht färben, in wäßrigen Medien behandelt.Process for dyeing cellulose esters It has been found that one. can easily dye solid cellulose esters, especially acetate silk, if these are used with non-acidylated aminoanthraquinones or their substitution products, which have a weakly basic character and do not dye natural fibers, treated in aqueous media.

Man hat bereits vorgeschlagen, Celluloseester unter Anwendung von Farbstoffen der Anthrachinonreihe zu färben. Es ist überraschend, daß man mit Aminoanthrachinonen, die keine Farbstoffe sind, gemäß der vorliegenden Erfindung auf festen Celluloseestern sehr 'leuchtende, satte Färbungen erzielen kann.It has already been proposed to use cellulose esters To dye dyes of the anthraquinone series. It is surprising that with aminoanthraquinones, which are not dyes, according to the present invention on solid cellulose esters very 'bright, rich colors.

Beispiel i i Äthylaminoanthrachinon wird in Ameisensäure oder Äthylenchlorhydrin oder einem anderen geeigneten Lösungsmittel gelöst, worauf diese Lösung in Wasser, dem Türkischrotöl zugesetzt ist, gegossen wird. Aus dem so erzeugten rotgefärbten Bad wird Acetatseä.de in lebhaften, blaustichigroten Tönen gefärbt. Beispiel z i # q.-Diaminoanthrachinon wird in Ameisensäure gelöst und mit dem gleichen Volumen einer i oprozentigen Lösung von Gummiarabikum in Wasser verdünnt, worauf die 5o- bis ioofache Menge Wasser von 6o bis 70° zugegeben wird. Aus diesem Bade wird Acetatseide in schönen blauvioletten Tönen gefärbt. Eine Mischung von 1.6- und 1#7-Diarnüioanthrachinon, in der gleichen Weise oder nach Vorschrift von. Beispiel i gefärbt, gibt ein lebhaftes Rot, 5-Nitroi # q.-diaminoanthrachinon ein Violett, 1. a . q.-Triamüioanthrachinon ein Rotviolett, 1 # 4.. 5 # 8-Tetraaminoanthrachinon ein Blau.Example i i Ethylaminoanthraquinone is in formic acid or ethylene chlorohydrin or another suitable solvent, whereupon this solution in water, to which Turkish red oil is added, is poured. From the red-colored one produced in this way Acetatseä.de bathroom is colored in lively, bluish-tinged red tones. Example z i # q.-Diaminoanthraquinone is dissolved in formic acid and with the same volume diluted with a 10 percent solution of gum arabic in water, whereupon the 50 until 100 times the amount of water from 6o to 70 ° is added. This bath becomes acetate silk colored in beautiful blue-violet tones. A mixture of 1.6 and 1 # 7 diarnuioanthraquinone, in the same way or as directed by. Example i colored gives a lively one Red, 5-nitroi # q.-diaminoanthraquinone a violet, 1. a. q.-Triamuioanthraquinone a red-violet, 1 # 4 .. 5 # 8-tetraaminoanthraquinone a blue.

Beispiel 3 Antrachinon-i-hydrazin wird in Äthylenchlorhydrin oder einem sonstigen geeigneten Lösungsmittel :gelöst und darauf die Lösung in die 5o- bis ioofache Menge Wasser, das eine geringe Menge Türkischrotöl oder ein anderes Schutzkolloid enthält, eingegossen. Acetatseide wird aus dieser Flotte in schönen blaustichigroten Tönen angefärbt. Durch Nachbehandeln mit Formaldehyd wird die Echtheit unter Aufhellung der Farbe wesentlich verbessert.Example 3 Anthraquinone-i-hydrazine is in ethylene chlorohydrin or another suitable solvent: dissolved and then pour the solution into the 5o- up to ten times the amount of water, a small amount of turkey red oil or another Contains protective colloid, poured. Acetate silk is made from this liquor in beautiful dyed bluish-tinged red tones. After treatment with formaldehyde, the authenticity significantly improved with lightening of the color.
