Im Falle der Drop on demand-Methode hingegen werden Tropfen nach Wunsch erzeugt und gedruckt; d.h. es werden nur dann Tropfen erzeugt, wenn dies für den Druck erforderlich ist. Die Erzeugung der Tropfen kann z.B. mittels eines Piezo-Inkjet-Kopfes oder mittels thermischer Energie (Bubble Jet) erfolgen. Bevorzugt ist für das erfindungsgemässe Verfahren der Druck nach der kontinuierlichen Ink-Jet-Methode.In the case of the ink jet printing process, individual drops of the ink are checked out sprayed onto a substrate using a nozzle. The continuous ink jet method is predominantly used for this as well as the drop on demand method. In the case of continuous The ink-jet method creates the drops continuously, not for printing required drops are drained into a collecting container and recycled. In case of Drop on demand method, however, drops are created and printed as desired; i.e. drops are only generated when this is necessary for printing. The Generation of the drops can e.g. by means of a piezo inkjet head or by means of thermal Energy (bubble jet). Pressure is preferred for the method according to the invention according to the continuous ink-jet method.
Als textile Fasermaterialien kommen insbesondere hydroxylgruppenhaltige Fasermaterialien in Betracht. Bevorzugt sind cellulosehaltige Fasermaterialien, die ganz oder teilweise aus Cellulose bestehen. Beispiele sind natürliche Fasermaterialien wie Baumwolle, Leinen oder Hanf und regenerierte Fasermaterialien wie z.B. Viskose sowie Lyocell. Besonders bevorzugt sind hierbei Viskose oder vorzugsweise Baumwolle. Die genannten Fasermaterialien liegen vorzugsweise als flächige textile Gewebe, Gewirke oder Bahnen vor.In particular, fiber materials containing hydroxyl groups come as textile fiber materials into consideration. Preference is given to cellulose-containing fiber materials which are made up entirely or in part Cellulose exist. Examples are natural fiber materials such as cotton, linen or Hemp and regenerated fiber materials such as Viscose and lyocell. Especially viscose or preferably cotton are preferred. The fiber materials mentioned are preferably in the form of flat textile fabrics, knitted fabrics or webs.
Gemäss einer bevorzugten Ausführungsform der vorliegenden Erfindung erfolgt vor dem Bedrucken eine Vorbehandlung des Fasermaterials, worin man das zu bedruckende Fasermaterial zuerst mit einer wässrigen alkalischen Flotte behandelt und das behandelte Fasermaterial gegebenenfalls trocknet.According to a preferred embodiment of the present invention, before Printing a pretreatment of the fiber material, in which one is to be printed Fiber material first treated with an aqueous alkaline liquor and the treated Fiber material dries if necessary.
Die wässrige alkalische Flotte enthält mindestens eine der üblichen Basen, welche in konventionellen Reaktivdruckverfahren zur Fixierung der Reaktivfarbstoffe eingesetzt werden. Die Base wird z.B. in einer Menge von 10 bis 100 g/l Flotte, vorzugsweise 10 bis 50 g/l Flotte, eingesetzt. Als Base kommen beispielsweise Natriumcarbonat, Natriumhydroxid, Dinatriumphosphat, Trinatriumphosphat, Natriumacetat, Natriumpropionat, Natriumhydrogencarbonat, wässriges Ammoniak oder Alkalispender, wie z.B. Natriumchloracetat oder Natriumformiat in Betracht. Vorzugsweise wird Natriumhydrogencarbonat, Natriumcarbonat oder eine Mischung aus Wasserglas und Natriumcarbonat verwendet. Der pH-Wert der alkalischen Flotte beträgt in der Regel 7,5 bis 13,5, vorzugsweise 8,5 bis 12,5. Die wässrige alkalische Flotte kann ausser den Basen weitere Zusätze, z.B. Hydrotropiermittel, enthalten. Als Hydrotropiermittel wird bevorzugt Hamstoff verwendet, der z.B. in einer Menge von 25 bis 200 g/l Flotte, vorzugsweise 50 bis 150 g/l Flotte eingesetzt wird. Vorzugsweise wird das Fasermaterial nach der obigen Vorbehandlung getrocknet.The aqueous alkaline liquor contains at least one of the usual bases, which in conventional Reactive printing processes are used to fix the reactive dyes. The base is e.g. in an amount of 10 to 100 g / l liquor, preferably 10 to 50 g / l Fleet, deployed. Sodium carbonate, sodium hydroxide, Disodium phosphate, trisodium phosphate, sodium acetate, sodium propionate, sodium hydrogen carbonate, aqueous ammonia or alkali dispensers, e.g. Sodium chloroacetate or sodium formate. Sodium bicarbonate is preferred, sodium carbonate or a mixture of water glass and sodium carbonate is used. The pH the alkaline liquor is usually 7.5 to 13.5, preferably 8.5 to 12.5. The aqueous alkaline liquor can contain other additives, e.g. Hydrotrope, contain. Urea is preferably used as the hydrotroping agent, e.g. in a Amount of 25 to 200 g / l liquor, preferably 50 to 150 g / l liquor is used. The fiber material is preferably dried after the above pretreatment.
Nach dem Bedrucken wird das Fasermaterial vorteilhafterweise getrocknet, vorzugsweise bei Temperaturen bis 150°C, insbesondere 80 bis 120°C, und anschliessend einem Hitzebehandlungsprozess unterworfen, um den Druck zu vervollständigen, bzw. den Farbstoff zu fixieren.After printing, the fiber material is advantageously dried, preferably at temperatures up to 150 ° C, especially 80 to 120 ° C, and then a heat treatment process subjected to complete the print, or the dye to fix.
Die Hitzebehandlung kann z.B. durch ein Warmverweilverfahren, einen Thermosolierprozess oder vorzugsweise durch ein Dämpfverfahren durchgeführt werden.The heat treatment can e.g. through a warm dwell process, a thermal insulation process or preferably be carried out by a steaming process.
Beim Dämpfverfahren wird das bedruckte Fasermaterial z.B. einer Behandlung in einem Dämpfer mit gegebenenfalls überhitztem Dampf, zweckmässigerweise bei einer Temperatur von 95 bis 180° C, vorteilhafterweise im Sattdampf, unterzogen.In the steaming process, the printed fiber material is e.g. one treatment in one Damper with possibly superheated steam, conveniently at one temperature from 95 to 180 ° C, advantageously in saturated steam.
Im Anschluss wird das bedruckte Fasermaterial in der Regel in üblicher Weise mit Wasser ausgewaschen um nichffixierten Farbstoff zu entfernen.Subsequently, the printed fiber material is usually washed with water in the usual way washed out to remove non-fixed dye.
