Description

Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Bedrucken von hydrophoben Fasermaterialien mit Dispersionsfarbstoffen nach dem Reservedruckverfahren.The present invention relates to a method for printing hydrophobic Fiber materials with disperse dyes using the reserve printing process.

Das Reservedruckverfahren mit Dispersionsfarbstoffen ist für hydrophobe Fasermaterialien bekannt. Das Bedrucken dieser Materialien, vor allem von Polyesterfasermaterialien, wird aber meistens mit einem sogenannten Ätzreserveverfahren durchgeführt, bei dem man den vorgefärbten oder vorgedruckten Grundfarbstoff durch eine Behandlung mit einem stark alkalischen Hilfsmittel örtlich zerstört und auf diese Stellen einen oder mehrere andere Farbstoffe, welche ätzresistent sein müssen, aufdruckt. Die Behandlung mit dem Ätzmittel ist aber sowohl ökologisch als auch ökonomisch mit Nachteilen verbunden; so kann z.B. das behandelte Fasermaterial durch die Einwirkung von starkem Alkali angegriffen und beschädigt werden.
Es besteht daher ein Bedürfniss nach einem einfacheren und faserschonenden Reservedruckverfahren für das Bedrucken von hydrophoben Fasermaterialien, insbesondere Polyesterfasermaterialien.The reserve printing process with disperse dyes is known for hydrophobic fiber materials. The printing of these materials, especially polyester fiber materials, is mostly carried out with a so-called etching reserve process, in which the pre-dyed or pre-printed basic dye is locally destroyed by treatment with a strongly alkaline auxiliary and one or more other dyes, which are resistant to etching, are applied to these areas have to print. However, treatment with the etchant is associated with disadvantages both ecologically and economically; For example, the treated fiber material can be attacked and damaged by the action of strong alkali.
There is therefore a need for a simpler and more gentle reserve printing process for printing on hydrophobic fiber materials, in particular polyester fiber materials.

Es hat sich überraschenderweise gezeigt, dass man mit dem erfindungsgemässen Verfahren das hydrophobe Fasermaterial faserschonend bedrucken kann, wobei der resultierende Druck gute Allgemeinechtheiten und insbesondere eine sehr gute Heisslichtechtheit aufweist.Surprisingly, it has been shown that the process according to the invention can print the hydrophobic fiber material in a way that is gentle on the fibers, the resulting Print has good general fastness properties and in particular a very good hot light fastness.

Gegenstand der vorliegenden Anmeldung ist somit ein Verfahren zum Bedrucken von hydrophoben Fasermaterialien mit Dispersionsfarbstoffen, welches dadurch gekennzeichnet ist, dass man die Fasermaterialien:

  • A) mit einem Dispersionsfarbstoff ganzflächig färbt oder ganzflächig bedruckt und
  • B) mit einer Druckpaste enthaltend mindestens einen Dispersionsfarbstoff, mindestens ein kationisches Hilfsmittel, und mindestens ein nichtionogenes Waschmittel stellenweise bedruckt, wobei die Schritte A) und B) in beliebiger Reihenfolge erfolgen können und der Schritt B) mit unterschiedlichen Farbstoffen mehrmals wiederholt werden kann, das so behandelte Fasermaterial trocknet und anschliessend den Farbstoff auf dem Fasermaterial durch eine Hitzebehandlung fixiert.
    • The subject of the present application is thus a process for printing hydrophobic fiber materials with disperse dyes, which is characterized in that the fiber materials are:
  • A) dyeing or printing the entire surface with a disperse dye and
  • B) partially printed with a printing paste containing at least one disperse dye, at least one cationic auxiliary, and at least one nonionic detergent, steps A) and B) being able to be carried out in any order and step B) being repeated several times with different dyes thus treated fiber material dries and then fixes the dye on the fiber material by heat treatment.

    • Als Dispersionsfarbstoffe eignen sich für das erfindungsgemässe Verfahren solche Farbstoffe, welche im Colour Index, 3. Auflage (3. Revision 1987 inclusive Additions and Amendments bis No. 85) unter "Disperse Dyes" beschrieben sind. Es sind beispielsweise carbonsäure- und/oder sulfosäuregruppenfreie Nitro-, Amino-, Aminoketon-, Ketoninim-, Methin-, Polymethin-, Diphenylamin-, Chinolin-, Benzimidazol-, Xanthen-, Oxazin- oder Cumarinfarbstoffe und insbesondere Anthrachinon- und Azofarbstoffe, wie Mono- oder Disazofarbstoffe.Suitable disperse dyes for the process according to the invention are those dyes which are in the Color Index, 3rd edition (3rd revision 1987 including additions and Amendments to No. 85) are described under "Disperse Dyes". For example carbonic acid and / or sulfonic acid group-free nitro, amino, aminoketone, ketoninim, Methine, polymethine, diphenylamine, quinoline, benzimidazole, xanthene, oxazine or coumarin dyes and in particular anthraquinone and azo dyes, such as mono- or disazo dyes.
