Description
Verfahren zum, Färben von Celluloseacetaten. Es ist seit längerer Zeit bekannt, daß Salze unter gleichzeitiger Anwesenheit von Säuren einen vorteilhaften Einfluß auf die Färbbarkeit der Acetatseide ausüben. So behandelt beispielsweise die deutsche Patentschrift ig8oo8 das Färben in Gegenwart von Essigsäure und essigsaurem Natrium. In der deutschen Patentschrift 355533 ist dann mitgeteilt, daß ganz allgemein Bädern, welche Salze und gleichzeitig Säuren enthalten, die Eigenschaft zukommt, die Färbefähigkeit der Acetatseide zu fördern.Process for dyeing cellulose acetates. It's been a long time Time known that salts in the simultaneous presence of acids have an advantageous Have an influence on the dyeability of the acetate silk. Treated like this, for example the German patent ig8oo8 dyeing in the presence of acetic acid and acetic acid Sodium. In the German patent 355533 it is stated that quite generally Baths that contain salts and acids at the same time have the property to promote the dyeing ability of the acetate silk.
Es wurde nun ein andersgeartetes, viel vorteilhafteres Verfahren zur Erreichung dieses Zieles gefunden, indem festgestellt wurde, daß ohne Säurezusatz mit basischen, sauren und einigen substantiven Farbstoffen kräftige Färbungen erzielt werden, wenn man dem Färbebade Ammoniumsalze, mit Ausnahme von Ammoniumthiocyanat, zugibt.There was now a different, much more advantageous method for Achievement of this goal was found by establishing that without the addition of acid strong colors achieved with basic, acidic and some substantive dyes if ammonium salts, with the exception of ammonium thiocyanate, are added to the dyebath admits.
Man färbt nach dem vorliegenden Verfahren vorteilhaft unterhalb des Siedepunktes der Färbeflotte; eine Schwächung der Ware durch Verseifung, Verlust des Glanzes, Wolligwerden usw. findet nicht statt. Beispiele i. i kg Acetatseide wird in einem Färbebad von 2o bis 25 1, in welchem 2o g Malachitgrün (G. S c h u 1 t z, Farbstofftabellen, 6. Aufl., Nr. 493) und 5oo g Ammoniumacetat gelöst sind, bei 5o' C eingegangen. Es wird langsam erwärmt und i Stunde bei 85 bis go ° gefärbt, darauf gespült und getrocknet. 2. = kg Acetatseide wird in einem Färbebad von 2o bis 25 1, in welchem 2o g Dianilgelb R (G. Schultz, Farbstofftabellen, 6. Aufl., Nr. 26) und 500 g Ammoniumsulfat gelöst sind, bei 50' C eingegangen. Es wird langsam erwärmt und i Stunde bei 85 bis go ° C gefärbt, darauf gespült und getrocknet.In the present process, dyeing is advantageously carried out below the boiling point of the dye liquor; a weakening of the goods through saponification, loss of shine, woolening, etc. does not take place. Examples i. 1 kg of acetate silk is placed in a dyebath of 20 to 25 liters, in which 20 g of malachite green (G. Schu 1 tz, Dye Tables, 6th edition, No. 493) and 500 g of ammonium acetate are dissolved, at 50 ° C. It is slowly heated and dyed for 1 hour at 85 to 0 °, then rinsed and dried. 2. = kg acetate silk is placed in a dyebath of 20 to 25 liters, in which 20 g dianil yellow R (G. Schultz, Dyestuff Tables, 6th edition, No. 26) and 500 g ammonium sulfate are dissolved, at 50 ° C. It is slowly heated and dyed for 1 hour at 85 to go ° C, then rinsed and dried.
3. i kg Acetatseide wird in einem Färbebad. von 2o bis 25 1, in welchem 2o g Echtrot O (G. Schultz, Farbstofftabellen, 6.Aufl., Nr.i6i) und 500 g Ammoniumformiat gelöst sind, bei 5o' C eingegangen. Es wird langsam erwärmt und i Stunde bei 85 bis go ° C gefärbt, darauf gespült und getrocknet.3. 1 kg of acetate silk is placed in a dye bath. from 2o to 25 1, in which 2o g of real red O (G. Schultz, Dye Tables, 6th edition, No. i6i) and 500 g of ammonium formate are dissolved, arrived at 5o'C. It is slowly heated and dyed for 1 hour at 85 to go ° C, then rinsed and dried.
4. 2 kg eines aus gleichen Teilen Acetatseide und Baumwolle gemischten Garnes werden in einem Färbebade von etwa 4ö 1, in welchem 2o g Azogelb konz. (G. Schultz, Farbstofftabellen, 6. Aufl., Nr. 14i), 2o g Dianilreinblau PH (G. Schultz, Farbstofftabellen, 6. Aufl., Nr. 49,4) und 5oo g Ammoniumacetat gelöst sind, bei 5o' C eingegangen. Es wird langsam erwärmt und i Stunde bei 85 bis go ° C gefärbt. Nach dem Färben wird gespült, leicht bei etwa 50' C geseift, mit etwas Essigsäure abgesäuert und getrocknet. Man erhält auf diese Weise Zweifarbeneffekte, indem der saure Farbstoff ausschließlich auf die Acetatseide, der direkte Farbstoff dagegen nur auf die Baumwolle zieht.4. 2 kg of a yarn mixed from equal parts of acetate silk and cotton are put in a dye bath of about 40 liters, in which 2o g of azo yellow conc. (G. Schultz, color tables, 6th edition, no. 14i), 20 g of dianiline blue PH (G. Schultz, color tables, 6th edition, no. 49.4) and 500 g of ammonium acetate are dissolved at 50 ° C received. It is slowly warmed up and dyed at 85 to 20 ° C. for 1 hour. After dyeing, it is rinsed, soaped gently at about 50 ° C., acidified with a little acetic acid and dried. In this way, two-color effects are obtained, in that the acidic dye is applied exclusively to the acetate silk, while the direct dye is only applied to the cotton.
Ähnliche Zweifarbeneffekte sind auch bei Anwendung von gemischten Geweben aus Acetatseide und anderen Fasern, wie Viskoseseide, Wolle usw., zu erzielen.Similar two-tone effects are also mixed when applying Fabrics made from acetate silk and other fibers such as viscose silk, wool, etc.
