Description

Verfahren zum Färben von Cellulosefasern oder von Mischungen von Cellulosefasern mit tierischen Fasern Es wurde gefunden, daß man Färbungen von sehr guten Echtheitseigenschaften auf Cellulosefasern oder Mischungen von Cellulosefasern mit tierischen Fasern, z. B. von Zellwolle aus Viscose oder Kupferoxyd ammoniakcellulose mit Wolle, herstellen kann, wenn man keine zur Metallkomplex bildung befähigte Gruppen enthaltende, wasserlösliche Azofarbstoffe, die die 2-Amino-5-oxynaphthalin-7-sulfonsäure oder deren Derivate und Substitutionsverbindungen als Azokomponente und mindestens einmal die Gruppe -N = N-R-NH², worin R einen aromatischen Rest bedeutet, enthalten, auf die Faser bringt und die Färbungen mit Mischungen aus Cobaltsalzen und Oxydationsmitteln behandelt. Es ist vorteilhaft, die Nachbehandlung der Färbungen in schwachsaurer Lösung und bei erhöhter Temperatur vorzunehmen. Als Oxydationsmittel sind insbesondere Chromate, Bichromate, Wasserstoffsuperoxyd, Persulfate oder Perborate geeignet.Process for dyeing cellulose fibers or mixtures of cellulose fibers with animal fibers It has been found that dyeings with very good fastness properties can be obtained on cellulose fibers or mixtures of cellulose fibers with animal fibers, e.g. B. from viscose rayon or copper oxide ammonia cellulose with wool can, if one does not contain any groups capable of forming a metal complex, water-soluble Azo dyes containing 2-amino-5-oxynaphthalene-7-sulfonic acid or its derivatives and substitution compounds as the azo component and at least once the group -N = N-R-NH², where R is an aromatic radical, on the fiber brings and treated the dyeings with mixtures of cobalt salts and oxidizing agents. It is advantageous to post-treat the dyeings in a weakly acidic solution and to be carried out at elevated temperature. Particularly suitable oxidizing agents are chromates, Bichromates, hydrogen peroxide, persulfates or perborates are suitable.

Vor dem bekannten Verfahren zum Färben von Cellulosefasern mit Metallverbindungen von. o, o' Dioxyazofarbstoffen, die 2 Amino-5-oxynaphthalin-7-sulfonsätire alkalisch kuppelt enthalten, und Behandeln mit Oxydationsmitteln zeichnet sich das vorliegende Verfahren durch eine größere Sicherheit des Färbevorganges aus. Die erzielten Färbungen sind wesentlich kräftiger als die nach dem bekannten Verfahren erhaltenen Färbungen und übertreffen diese in der Wasch- und Schweißechtheit.Before the known method of dyeing cellulose fibers with metal compounds from. o, o 'Dioxyazo dyes, the 2 amino-5-oxynaphthalene-7-sulfonsätire alkaline Couples containing, and treating with oxidizing agents distinguishes the present Procedure through greater security of the dyeing process. The colorations achieved are much stronger than the colorations obtained by the known process and surpass them in terms of their fastness to washing and perspiration.

Beispiele r. Ein Gemisch aus 5o Teilen Wolle und 5o Teilen Zellwolle aus Viscose wird in einer Lösung gefärbt, welche 5 °/o des Natrium - , Salzes des reduzierten Azofarbstoffes I-Amino 3, 5-dinitrobenzol sauer 2-Amino-5-oxynaphthalin-7-sulfonsäure, 8 % Ammoniumsulfat und 6o% Natriumsulfat enthält. Die Prozentzahlen sind auf das Gewicht des Färbegutes bezogen. Man färbt I Stunde bei 75° C und läßt eine weitere Stunde bei 65' C abkühlen Dann wird gespült und 3/4 Stunde bei 9o° C in einem Bade behandelt, welches 2 % Cobaltchlorür, 6%, Wasserstoffsuperoxydlösung 30%ig und 2 % Essigsäure 5o%ig enthält, gespült und getrocknet. Man erhält ein Dunklelbraun von sehr guten Echtheitseigenschaften.Examples r. A mixture of 50 parts of wool and 50 parts of viscose rayon is dyed in a solution which contains 5% of the sodium, salt of the reduced azo dye I-amino 3, 5-dinitrobenzene acidic 2-amino-5-oxynaphthalene-7-sulfonic acid, 8% ammonium sulfate and 6o% sodium sulfate. The percentages are based on the weight of the material to be dyed. It is dyed for 1 hour at 75 ° C and allowed to cool for a further hour at 65 ° C. Then it is rinsed and treated for 3/4 hour at 90 ° C in a bath containing 2% cobalt chloride, 6%, hydrogen peroxide solution 30% and 2% Contains acetic acid 5o%, rinsed and dried. A dark brown with very good fastness properties is obtained.

Der Stoff wird getrocknet und mit einer Lösung geklotzt, die Iog Cobaltchlorür. 5 ccm Wasserstoffsuperoxydlöstung 30%ig oder 2og Natriumpersulfat oder 2o g Natriumperborat oder 20 g Kaliumbichromat und Io ccm Essigsäure 5o%ig in I ooo ccm kochend heißen Wassers enthält. Dann wird gespült, kurz geseift und getrocknet. Man erhält ein Braun von guten Echt heitseigenschaften.z. Cotton fabric is padded with a solution containing 30g of the sodium salt de reduced azo dye I amino-2-chloro-4-nitrobenzene acid 2-amino-5-oxynaphthalene-4-nitrobenzene acid 2-amino-5-oxynaphthalene 7-sulfonic acid and contains 3 g of sodium hydroxide in 1,000 cubic centimeters of water. The fabric is dried and padded with a solution, the Iog cobalt chloride. Contains 5 cc hydrogen peroxide solution 30% or 2og sodium persulphate or 20 g sodium perborate or 20 g potassium dichromate and 10 cc acetic acid in 100 cc boiling water. Then it is rinsed, soaped briefly and dried. A brown with good authenticity properties is obtained.
