Description
Verfahren zumVerbessern derWiderstandsfähigkeit von mit Küpenfarbstoffen gefärbten Cellulosefasern gegen faserschädigende Lichteinwirkung Es ist bekannt, daß Baumwolle-, Cellulosekunstseide- und Cellulosezellwollfas ern durch die Färbung mit gewissen Küpenfarbstoffen nach längerer Belichtung eine mehr oder weniger große Faserschädigung erleiden (vgl. Fierz-David: Künstliche organische Farbstoffe, Ergänzungsband, S. 74). Solche Farbstoffe sind z. B. die folgenden: 2, 2'-Bisoxythionaphthenindigo, 4, 4'-Dimethyl-2, 2'-bisoxythionaphthenindigo, 4, 4'-Dimethyl-6, 6'-dichlor-2, 2'-bisoxythionaphthenindigo, 6, 6'-Dichlor-2, 2' bisoxythionaphthenin,digo, 6, 6'-Diäthoxy-2, 2'-bisoxythionaphthenindigo, 4-Methyl-6-chlor-6'-methoxy-2, 2'-bisoxythionaphthenindigo, 4, 4'-Dimethyl-5, 7, 5', 7'-tetrachlor-2, 2'-bisoxythionaphthenindigo, 5, 5'-Dichlor-7, 7'-dimethyl-2, 2'-bisoxythionaphthenindigo, 2, 1,2', I'-Bisnaphthoxythiophenindigo, 2, I, I', 2'-Bisnaphthoxythiophenindigo, I, 2, I', 2'-Bisnaphthoxythiophenindigo, I-Benzoylaminoanthrachinon, I, 5-Dibenzoylaminoanthrachinon, I, 4-Dibenzoylaminoanthrachinon, I, 8-Dibenzoylaminoanthrachinon, I, 2, 3-Tribenzoyltriaminoanthrachinon, Terephthaloyl-I, I'-diaminodianthrachinon,Isotherephthaloyl-I, I'-diaminodianthrachinon, 3, 4, 8, 9-Dibenzpyren-5, Io-chinon und Halogenabkömmlinge, I, 2, 7, 8-Diphthaloylcarbazol, I (N),2, 5 (N) 6-Anthrachinondibenzthiazol, Farbstoff aus 2-Anthrachinonaldehyd und Benzidin mit nachfolgender Verschwefelung, Farbstoff aus 2-Anthrachinonaldehyd und I, 4-Diaminobenzol mit nachfolgender Verschwefelung, I, 2'-Dianthrachinonylamin und Halogenabkömmlinge, Farbstoff, erhalten durch Wasserabspaltung von 2, 2'-Dimethyl-i, i'-danthrachinonyl, und Halogenabkömmlinge.Method for improving the resistance of vat dyes dyed cellulose fibers against fiber-damaging exposure to light It is known that cotton, cellulose rayon and cellulose cellulose fibers by the dyeing with certain vat dyes a more or less large one after prolonged exposure Suffer fiber damage (see Fierz-David: Artificial organic dyes, supplementary volume, P. 74). Such dyes are e.g. B. the following: 2, 2'-bisoxythionaphthene indigo, 4, 4'-dimethyl-2, 2'-bisoxythionaphthene indigo, 4, 4'-dimethyl-6, 6'-dichloro-2, 2'-bisoxythionaphthene indigo, 6, 6'-dichloro-2, 2 'bisoxythionaphthenin, digo, 6, 6'-diethoxy-2, 2'-bisoxythionaphthenindigo, 4-methyl-6-chloro-6'-methoxy-2, 2'-bisoxythionaphthenindigo, 4, 4'-dimethyl-5, 7, 5 ', 7'-tetrachlor-2, 2'-bisoxythionaphthene indigo, 5, 5'-dichloro-7, 7'-dimethyl-2, 2'-bisoxythionaphthenindigo, 2, 1,2 ', I'-bisnaphthoxythiophenindigo, 2, I, I', 2'-bisnaphthoxythiophenindigo, I, 2, I ', 2'-Bisnaphthoxythiophenindigo, I-Benzoylaminoanthraquinone, I, 5-Dibenzoylaminoanthraquinone, I, 4-dibenzoylaminoanthraquinone, I, 8-dibenzoylaminoanthraquinone, I, 2, 3-tribenzoyltriaminoanthraquinone, Terephthaloyl-I, I'-diaminodianthraquinone, isotherephthaloyl-I, I'-diaminodianthraquinone, 3, 4, 8, 9-dibenzpyrene-5, io-quinone and halogen derivatives, I, 2, 7, 8-diphthaloylcarbazole, I (N), 2, 5 (N) 6-anthraquinone dibenzothiazole, dye from 2-anthraquinone aldehyde and benzidine with subsequent sulphurisation, dye from 2-anthraquinone aldehyde and I, 4-diaminobenzene with subsequent sulphurization, I, 2'-dianthraquinonylamine and halogen derivatives, dye obtained by dehydration of 2,2'-dimethyl-i, i'-danthraquinonyl, and halogen derivatives.
Da diese Farbstoffe im übrigen wertvolle Eigenschaften besitzen, so besteht das technische Interesse, Mittel zu finden, um die faserschädigenden Eigenschaften dieser Farbstoffe auszuschalten.Since these dyes also have valuable properties, so there is technical interest in finding a means to reduce the fiber-damaging properties to turn off these dyes.
Es wurde nun gefunden, daß eine Faserschädigung bei Verwendung solcher Farbstoffe nicht oder im wesentlich geringeren Maße eintritt, wenn man die gefärbte Faser mit- Bädern nachbehandelt, die Sulfamid, Haunstoff oder Thioharnstoff enthalten, und trocknet.It has now been found that fiber damage when using such Dyes does not occur or occurs to a much lesser extent if the dyed fiber is aftertreated with baths containing sulfamide, skin fabric or thiourea included, and dries.
Zur Nachbehandlung von Färbungen mit Dithioallkylthioindigofarbstoffen auf pflanzlichen Fasern sind bereits Kupfer- und Eisensalze vorgeschlagen worden, um die Fasern gegen schädigende Lichteinwirkung zu schützen. Vergleichende Versuche haben gezeigt, daß durch Anwendung der obengenannten Säureamide ein wesentlich besserer Schutz der mit Küpenfarbstoffen gefärbten Fasern gegen Schädigungen durch Lichteinwirkung erzielt wird. Beispiele I. Baumwolle wird mit dem Farbstoff 6, 6'-Diäthoxybisoxythionaphthenindigo gefärbt. Die gefärbte Ware wird mit einem Bade, das 2 % Harnstoff enthält, bei 2o bis 4o° C nachbehandelt und getrocknet. Wird die Färbung belichtet, so zeigt sich nach einem halben Jahr, daß die nicht nachbehandelte gefärbte Ware vollkommen morsch geworden ist, während das nachbehandelte Färbegut in der Festigkeit unverändert geblieben ist.For the aftertreatment of dyeings with dithioalkylthioindigo dyes Copper and iron salts have already been proposed on vegetable fibers, to protect the fibers against the harmful effects of light. Comparative trials have shown that by using the above acid amides a much better Protection of the fibers dyed with vat dyes against damage caused by exposure to light is achieved. Examples I. Cotton is dyed with 6,6'-diethoxybisoxythionaphthene indigo colored. The dyed goods are treated with a bath containing 2% urea at 2o Treated to 40 ° C and dried. If the color is exposed, it shows after half a year that the untreated dyed goods are completely rotten has become, while the strength of the aftertreated dyed material remains unchanged stayed.
2. Kupferkunstseide wird mit dem Farbstoff I, 2, 7, 8-Diphthaloylcarbazolgefärbt. Die gefärbte Ware wird mit einem Bade, das 2%o Thioharnstoff enthält, eine halbe Stunde bei 2o bis 4o° C nachbehandelt und getrocknet. Wird das Färbegut im Vergleich mit dem nicht nachbehandelten sechs Wochen belichtet und danach die Reißfestigkeit bestimmt, so zeigt sich, daß die nicht nachbehandelte gefärbte Ware etwa um 8o% der ursprünglichen Reißfestigkeit eingebüßt hat, während die nachbehandelte gefärbte Ware nur eine um etwa Ioo% verringerte Festigkeit zeigt.2. Copper rayon is dyed with dye I, 2, 7, 8-diphthaloylcarbazole. The dyed goods are half a bath with a bath containing 2% thiourea Aftertreated and dried at 2o to 4o ° C for an hour. Will the dyed goods in comparison exposed to the untreated six weeks and then the tear strength determined, it can be seen that the non-aftertreated dyed goods by about 80% has lost its original tear strength, while the post-treated dyed one Goods only shows a strength reduced by about 100%.
3. Viscosezellwolle wird mit dem Farbstoff I, 5-Dibenzoylaminoanthrachinon gefärbt. Die gefärbte Ware wird mit einem Bade, das 2% Sulfamid (N H2 S 02 N H2) enthält, eine halbe Stunde bei 2o bis 4o° C behandelt und getrocknet. Wird die gefärbte Ware 6 Wochen belichtet und die Reißfestigkeit geprüft, so zeigt sich, daß das nicht nachbehandelte Färbegut einen Festigkeitsverlust von etwa 6o% aufweist, während der des nachbehandelten Färbegutes nur etwa 15%, beträgt.3. Viscose cellulose is with the dye I, 5-dibenzoylaminoanthraquinone colored. The dyed goods are treated with a bath containing 2% sulfamide (N H2 S 02 N H2) contains, treated for half an hour at 2o to 4o ° C and dried. Will the stained If the goods were exposed for 6 weeks and the tear resistance was tested, it was found that this was not the case post-treated dyed goods show a loss of strength of about 6o%, while that of the aftertreated material to be dyed is only about 15%.
