Description

Verfahren zur Herstellung violetter Färbungen auf Celluloseestern und -äthern Ein wichtiges Verfahren zum Färben von Celluloseestern und -äthern und daraus hergestellten Textilien besteht darin, daß man derartiges Material mit Basen in echter Lösung oder kolloider Form behandelt, die aufgezogene Base dianotiert und mit Entwicklern kuppelt. Man erhält auf diese Weise Färbungen, die sich durch eine gute Wasch-, Wasser- und Überfärbeechtheit auszeichnen und zum Teil auch eine sehr gute Lichtechtheit besitzen. Es gelingt mit den zu diesem Zweck bisher verwendeten Basen eine ganze Reihe von Farbtönen, von Gelb über Rot bis Bordeaux sowie Blau und Schwarz, herzustellen, doch war es auf diesem Wege nicht möglich, zu einem lebhaften, echten Violett zu gelangen.Process for the production of purple colorations on cellulose esters and ethers An important process for coloring cellulose esters and ethers and Textiles made from it consists in that one such material with bases treated in real solution or colloidal form, the drawn-up base is dianotized and couples with developers. In this way, colorations are obtained that show through are characterized by good fastness to washing, water and over-dyeing, and in some cases also have very good lightfastness. It succeeds with those previously used for this purpose Bases a whole range of colors, from yellow to red to bordeaux and blue and black, but it was not possible in this way to produce a lively, to get real purple.

Es wurde nun gefunden, daß man schöne echte Violettfärbungen auf Celluloseestern und -äthern, besonders auf Acetatseide, erhält, wenn man dianotierte .4-Atnino-6-acylaminoresorcindialkyl- oder -diaryläther oder ihre Substitutionsprodukte auf der zu färbenden Substanz mit 2-3-Oxynaphthoesäure oder ihren Arylaminoderivaten kuppelt. Die Färbungen zeichnen sich durch vorzügliche Wasch-, Wasser-, Überfärbe- und Chlorechtheit aus und besitzen auch eine gute Lichtechtheit. Gerade die Überfärbeechtheit dieser Kombinationen ist besonders wertvoll, da die mit direkt ziehenden Farbstoffen auf Acetatseide erhältlichen Violettfärbungen diese Eigenschaft gar nicht oder nur in geringem Maße besitzen. Infolgedessen eignen sich die neuen Kombinationen besonders für Effektfäden auf Acetatseide in Mischgeweben, die heiß überfärbt werden müssen. Beispiele i. i kg Acetatseide wird in ein Färbebad von q.o Litern, in welchem 20 g q.-Amino-6-benzoylaminoresorcindimethyläther mit der zehnfachen Menge Türkischrotöl gelöst sind, eingebracht. Es wird langsam erwärmt und % Stunden bei 7o bis j5° umgezogen. Darauf wird gespült, wie üblich '/2 Stunde in einem frischen Bade dianotiert und in einem weiteren Bade mit 2-3-Oxynaphthoesäure t Stunde bei 5o° C schwach essigsauer entwickelt.It has now been found that beautiful, true violet colorations on cellulose esters and ethers, especially on acetate silk, are obtained if dianotated .4-Atnino-6-acylaminoresorcine dialkyl or diaryl ethers or their substitution products on the substance to be colored with 2-3- Oxynaphthoic acid or its arylamino derivatives. The dyeings are distinguished by excellent fastness to washing, water, over-dyeing and chlorine, and they also have good lightfastness. The fact that these combinations are fast to over-dyeing is particularly valuable, since the violet dyeings obtainable with direct dyes on acetate silk do not have this property at all or only to a small extent. As a result, the new combinations are particularly suitable for effect threads on acetate silk in blended fabrics that have to be hot-dyed. Examples i. 1 kg of acetate silk is placed in a dyebath of qo liters in which 20 g of q-amino-6-benzoylaminoresorcine dimethyl ether are dissolved with ten times the amount of Turkish red oil. It is warmed up slowly and moved for ½ hours at 70 to 5 °. It is then rinsed, dianotized for 1/2 hour in a fresh bath as usual, and developed in a further bath with 2-3-oxynaphthoic acid for t hour at 50 ° C. to be weakly acetic acid.

Die Base kann statt mit Türkischrotöl auch mit Salzsäure gelöst werden. In diesem Falle fügt man nach halbstündigem Färben dem Färbebade zum Abstumpfen der freien Säure Ammonium- oder Natriumacetat zu. Man erhält auf diese Weise ein kräftiges klares Blattvioleft"__,_ a. Statt der in- Beispiel r genannten Base nimmt mgn hier-_:=.o-6-acetylaminoresorcindiäthyläther und färbt wie oben. Man erhält ebenfalls eine schöne blauviolette Färbung.The base can also be dissolved with hydrochloric acid instead of Turkish red oil. In this case, after half an hour of dyeing, it is added to the dye bath to make it blunt ammonium or sodium acetate to the free acid. One receives on in this way a strong, clear sheet of foliage "__, _ a. Instead of those mentioned in example r Base takes mgn here -_: =. O-6-acetylaminoresorcindiethylether and colors as above. A beautiful blue-violet coloration is also obtained.

3. i kg. Aeetatseide wird wie in Beispiel i vorgefärbt, man' "diazotiert wie üblich und entwickelt in einem frischen Bade mit einer schwach essigsauer gemachten Lösung von 50 g a, 3-Oxynaphthoesäureanilid -{- So ccm Natronlauge 3q.° Be, gegebenenfalls unter Zusatz eines Schutzkolloids in q.o Liter Wasser i Stunde bei 5o° C. Man erhält auf diese Weise eine rotviolette Färbung von sehr guten Echtheitseigenschaften.3. i kg. Acetate silk is pre-dyed as in Example 1, diazotized as usual and developed in a fresh bath with a solution of 50 ga, 3-oxynaphthoic acid anilide - {- So ccm sodium hydroxide solution 3q. ° Be, if necessary with the addition of a protective colloid in qo liter of water for one hour at 50 ° C. A red-violet dyeing with very good fastness properties is obtained in this way.
