Description

Verfahren zum Drucken von Pigmenten auf Textilgeweben mit Acetylcellulose als Fixierungsmittel. ES wurde die bemerkenswerte Beobachtung gemacht, daß die mit Hilfe von Salzen, wie Rhodansalzen, z. B. nach den Angaben der Patentschriften 256922, 268627 und 28137q. herstellbaren Acetylcellelluloselösungen, im Pigmentdruck wertvolle Resultate liefern. Sie sind geeignet, die bisher zur Herstellung von Pigmentdrucken auf Geweben verwendeten Lösungen zu ersetzen. Die Acetylcellulose, welche bisher als Fixierungsmittel für Pigmente auf Textilmaterialien diente, wurde für diesen Zweck in 40prozentiger Essigsäure oder in Gemischen von Phenol, Formaldehyd, Alkohol oder Resorcin und Alkohol usw. aufgelöst (s. Leipziger Färberzeitung 1913, Seite 211 ff.). Das Arbeiten mit solchen Druckfarben ist wegen des stechenden Geruchs der Essigsäure und des Formaldehyds sehr lästig; auch die Hände der Arbeiter werden durch unvermeidliche Berührung von diesen Druckfarben stark angegriffen. Andererseits trocknen derartige Lösungen sehr rasch ein, wodurch viele Anwendungsmöglichkeiten ausgeschlossen werden.Process for printing pigments on textile fabrics with acetyl cellulose as a fixing agent. The remarkable observation has been made that with the aid of salts such as rhodan salts, e.g. B. according to the information in patents 256922, 268627 and 28137q. acetyl cellulose solutions that can be produced, deliver valuable results in pigment printing. They are suitable to replace the solutions previously used to produce pigment prints on fabrics. The acetyl cellulose, which previously served as a fixative for pigments on textile materials, was dissolved for this purpose in 40 percent acetic acid or in mixtures of phenol, formaldehyde, alcohol or resorcinol and alcohol, etc. (see Leipziger Färberzeitung 1913, page 211 ff.). Working with such printing inks is very annoying because of the pungent smell of acetic acid and formaldehyde; The hands of the workers are also severely attacked by inevitable contact with these printing inks. On the other hand, such solutions dry up very quickly, which excludes many possible uses.

Die mit Hilfe von Salzlösungen hergestellten Pigmentdruckfarben zeigen diese Übelstände nicht, sie erfordern. keine besonderen Vorsichtsmaßregeln; die mit ihnen hergestellten Drucke besitzen gute Echtheitseigenschaften. Beispiel. Man löst durch Stehenlassen bei Zimmertemperatur oder durch leichtes Erwärmen x2o g Acetylcellulose- in einer Lösung von 23o g Rhodancalcium in 65o g Wasser auf. Dieser dickflüssigen Lö- sung setzt man qoo g Blanc-fixe i. Tg., 75prozentig, ge- mischt mit xoo g Wasser zu 15009. Anstelle von Blanc-fixe i. Tg. kann ein beliebig anderes Pigment, z. B. chromsaures Blei oder Ultramarin bzw. Metallbronze, verwendet werden.The pigment printing inks produced with the help of salt solutions do not show these deficiencies, they require. no special precautions; the prints produced with them have good fastness properties. Example. Dissolve by letting it stand at room temperature or by gentle warming x2o g of acetyl cellulose in a solution of 23o g rhodan calcium in 65o g of water. This thick liquid sung is set qoo g Blanc-fixe i. Day, 75 percent, mixes with xoo g of water too 15009. Instead of Blanc-fixe i. Any other pigment, e.g. B. chromic acid lead or ultramarine or metal bronze can be used.

Nach dem Aufdruck wird getrocknet, dann gespült oder nach Bedarf bei Mitdruck von Dampffarhen gedämpft und gewaschen.After the print, it is dried, then rinsed or as required Steamed and washed with the pressure of steam horses.

Statt Rhodansalzen können andere der z. B. in den obengenannten Patenten aufgeführten Salze verwendet werden.Instead of rhodan salts, other z. B. in the aforementioned patents listed salts are used.
