Definitions
- the present invention relates to a method for printing textile fiber materials using the inkjet printing method.
- Inkjet printing processes have been used in the textile industry for several years.

Description
Verfahren zum Bedrucken von textilen Fasermaterialien nach dem Tintenstrahldruck- VerfahrenProcess for printing textile fiber materials according to the inkjet printing process
Die vorliegende Erfindung betrifft ein Verfahren zum Bedrucken von textilen Fasermaterialien nach dem Tintenstrahldruck-Verfahren.The present invention relates to a method for printing textile fiber materials using the inkjet printing method.
Tintenstrahldruck- Verfahren werden bereits seit einigen Jahren in der Textilindustrie angewendet. Diese Verfahren ermöglichen es, auf die sonst übliche Herstellung einer Druckschablone zu verzichten, so dass erhebliche Kosten- und Zeiteinsparungen erzielt werden können. Insbesondere bei der Herstellung von Mustervorlagen kann innerhalb deutlich geringerer Zeit auf veränderte Bedürfnisse reagiert werden.Inkjet printing processes have been used in the textile industry for several years. These methods make it possible to dispense with the otherwise customary production of a printing stencil, so that considerable cost and time savings can be achieved. In particular in the production of sample templates, it is possible to react to changing needs within a significantly shorter time.
Entsprechende Tintenstrahldruck-Verfahren sollten insbesondere optimale anwendungstechnische Eigenschaften aufweisen. Zu erwähnen seien in diesem Zusammenhang Eigenschaften wie die Viskosität, Stabilität, Oberflächenspannung und Leitfähigkeit der verwendeten Tinten. Ferner werden erhöhte Anforderungen an die Qualität der erhaltenen Drucke gestellt, wie z.B. bezüglich Farbstärke sowie Nassechtheits- eigenschaften. Von den bekannten Verfahren werden diese Anforderungen nicht in allen Eigenschaften erfüllt, so dass weiterhin ein Bedarf nach neuen Verfahren für den textilen Tintenstrahldruck besteht.Corresponding inkjet printing processes should in particular have optimal application properties. In this context, properties such as the viscosity, stability, surface tension and conductivity of the inks used should be mentioned. There are also increased demands on the quality of the prints obtained, e.g. with regard to color strength and wet fastness properties. The known processes do not meet all of these requirements in all properties, so that there is still a need for new processes for textile inkjet printing.

Das erfindungsgemässe Verfahren zum Bedrucken von textilen Fasermaterialien kann mit an und für sich bekannten für den textilen Druck geeigneten Tintenstrahldruckern ausgeführt werden.The method according to the invention for printing on textile fiber materials can be carried out with ink jet printers known per se and suitable for textile printing.
Im Falle des Tintenstrahldruck-Verfahrens werden einzelne Tropfen der Tinte kontrolliert aus einer Düse auf ein Substrat gespritzt. Ueberwiegend werden hierzu die kontinuierliche InkJet-Methode sowie die Drop on demand-Methode verwendet. Im Falle der kontinuierlichen Ink-Jet-Methode werden die Tropfen kontinuierlich erzeugt, wobei nicht für den Druck benötigte Tropfen in einen Auffangbehälter abgeleitet und rezykliert werden. 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 mittels eines Piezo-Inkjet-Kopfes. Bevorzugt ist für das erfindungsgemässe Verfahren ferner der Druck nach der kontinuierlichen Ink-Jet-Methode.In the case of the inkjet printing process, individual drops of the ink are sprayed from a nozzle onto a substrate in a controlled manner. The continuous inkjet method and the drop on demand method are mainly used for this. In the case of the continuous ink-jet method, the drops are generated continuously, with drops not required for printing being discharged into a collecting container and recycled. In the case of the drop on demand method, however, drops are created and printed as desired; ie drops are only generated if this is necessary for printing. The drops can be generated, for example, using a piezo inkjet head or using thermal energy (bubble jet). Printing using a piezo inkjet head is preferred for the method according to the invention. For the process according to the invention, printing by the continuous ink-jet method is also preferred.
Als textile Fasermaterialien kommen insbesondere stickstoffhaltige oder hydroxygruppenhaltige Fasermaterialien, wie z.B. textile Fasermaterialien aus Cellulose, Seide oder insbesondere Wolle oder synthetischen Polyamiden, in Betracht.As textile fiber materials come in particular nitrogen-containing or hydroxyl-containing fiber materials, such as textile fiber materials made of cellulose, silk or in particular wool or synthetic polyamides.
Nach dem erfindungsgemässen Verfahren wird besonders bevorzugt Seide oder seidenhaltiges gemischtes Fasermaterial bedruckt. Als Seide kommt nicht nur die Naturoder Zuchtseide (Maulbeerseide, Bombyx mori) sondern auch die verschiedenen Wildseiden, vor allem Tussahseide, ferner Eri- und Fagaraseiden, Nesterseide, Senagalseide, Mugaseide, sowie Muschel- und Spinnseide in Betracht. Seidenhaltige Fasermaterialien sind insbesondere Mischungen von Seide mit Polyesterfasern, Acrylfasern, Cellulosefasern, Polyamidfasern oder Wolle. Das genannte Textilmaterial kann dabei in den verschiedensten Verarbeitungsformen vorliegen, z.B. als Faser, garn, Gewebe oder Gewirke.According to the method according to the invention, silk or silk-containing mixed fiber material is particularly preferably printed. Not only natural or cultivated silk (mulberry silk, Bombyx mori) but also the various wild silk, especially Tussah silk, also Eri and Fagara silk, nest silk, Senagale silk, Mugase silk, as well as shell and spider silk come into consideration as silk. Silk-containing fiber materials are in particular mixtures of silk with polyester fibers, acrylic fibers, cellulose fibers, polyamide fibers or wool. The textile material mentioned can be in a wide variety of processing forms, e.g. as fiber, yarn, woven or knitted fabric.
Für das Bedrucken von Seide oder seidenhaltigem Fasermaterial wird bevorzugt eine Vorbehandlung des Fasermaterials ausgeführt. Hierzu wird das Fasermaterial mit einer wässrigen Flotte, enthaltend ein Verdickungsmittel und gegebenenfalls ein Hydrotropiermittel, vorbehandelt. Als Verdickungsmittel werden bevorzugt Alginatverdicker, wie handelsübliche Natriumalginatverdicker, verwendet, die z.B. in einer Menge von 50 bis 200 g/l Flotte, vorzugsweise 100 bis 200 g/l Flotte eingesetzt werden. Als Hydrotropiermittel wird bevorzugt Harnstoff verwendet, der z.B. in einer Menge von 25 bis 200 g/l Flotte, vorzugsweise 25 bis 75 g/l Flotte eingesetzt wird. Ferner kann die Flotte noch weitere Zusätze, wie z.B. Ammoniumtartrat, enthalten. Vorzugsweise wird die Flotte gemass dem Foulard-Verfahren auf das Fasermaterial appliziert, insbesondere bei einer Flottenaufnahme von 70 bis 100%. Bevorzugt wird das Fasermaterial nach der obigen Vorbehandlung getrocknet.
Gemäss dem erfindungsgemässen Verfahren können auch natürliche oder synthetische Polyamidfasermaterialien eingesetzt werden. Als natürliches Polyamidfasermaterial kommt insbesondere Wolle in Betracht. Als synthetisches Polyamidfasermaterial kommen z.B. Polyamid-6- und Polyamid-66-Fasermaterialien in Betracht.A pre-treatment of the fiber material is preferably carried out for printing on silk or silk-containing fiber material. For this purpose, the fiber material is pretreated with an aqueous liquor containing a thickener and optionally a hydrotroping agent. Alginate thickeners, such as commercially available sodium alginate thickeners, are preferably used as thickeners and are used, for example, in an amount of 50 to 200 g / l liquor, preferably 100 to 200 g / l liquor. Urea is preferably used as the hydrotrope, which is used, for example, in an amount of 25 to 200 g / l liquor, preferably 25 to 75 g / l liquor. The liquor can also contain other additives, such as ammonium tartrate. The liquor is preferably applied to the fiber material in accordance with the padding process, in particular with a liquor absorption of 70 to 100%. The fiber material is preferably dried after the above pretreatment. Natural or synthetic polyamide fiber materials can also be used in accordance with the method according to the invention. Wool is particularly suitable as a natural polyamide fiber material. Examples of suitable synthetic polyamide fiber materials are polyamide 6 and polyamide 66 fiber materials.
Nach dem Bedrucken wird das Fasermaterial gegebenenfalls getrocknet, vorzugsweise bei Temperaturen bis 150°C, insbesondere 80 bis 120°C, und anschliessend einem Hitze- behandlungsprozess unterworfen, um den Druck zu vervollständigen, bzw. den Farbstoff zu fixieren.After printing, the fiber material is optionally dried, preferably at temperatures up to 150 ° C., in particular 80 to 120 ° C., and then subjected to a heat treatment process in order to complete the print or to fix the dye.
Die Hitzebehandlung kann z.B. durch ein Warmverweilverfahren, einen Thermosolierprozess oder vorzugsweise durch ein Dämpfverfahren durchgeführt werden.The heat treatment can e.g. be carried out by a warm dwell process, a thermal insulation process or preferably by a steaming process.
Beim Dämpfverfahren wird das bedruckte Fasermaterial z.B. einer Behandlung in einem Dämpfer mit gegebenenfalls überhitztem Dampf, z.B. bei einer Temperatur von 95 bis 180°C, vorteilhafterweise bei 95 bis 130°C, insbesondere im Sattdampf, unterzogen.In the steaming process, the printed fiber material is e.g. treatment in a steamer with possibly superheated steam, e.g. at a temperature of 95 to 180 ° C, advantageously at 95 to 130 ° C, especially in saturated steam.
Im Anschluss wird das bedruckte Fasermaterial in der Regel in üblicher Weise mit Wasser ausgewaschen.The printed fiber material is then usually washed out with water in the customary manner.
Sowohl der Ink-Jet Druck, als auch die nachfolgende Trocknung und die Fixierung können auch in einem einzigen Schritt ausgeführt werden. Gemeint ist hiermit insbesondere, dass diese Schritte kontinuierlich ausgeführt werden. D.h. dass hintereinander Apparaturen für den Ink-Jet Druck, die Trocknung und die Fixierung angebracht sind, durch welche das zu bedruckende Fasermaterial kontinuierlich hindurch bewegt wird. Die Apparaturen für den Ink-Jet Druck, die Trocknung und die Fixierung können auch in einer einzigen Maschine vereint sein. Das Fasermaterial wird kontinuierlich durch diese Maschine transportiert und ist dann nach Verlassen dieser Maschine fertiggestellt. Die Trocknung kann hierbei z.B. mittels thermischer Energie (wie z.B. oben angegeben) oder insbesondere mittels Infrarotstrahlung (IR) erfolgen. Die Fixierung kann hierbei z.B. mittels Ultraviolettstrahlung (UV) oder mittels thermischer Energie (wie z.B. oben angegeben) erfolgen. Selbstverständlich kann auch der Ink-Jet Druck separat erfolgen und Trocknung und Fixierung werden wie oben angegeben kontinuierlich, z.B. in einer einzigen Maschine, ausgeführt.
Mit den oben genannten Druckverfahren ist es möglich, die Fasermaterialien sowohl in einer einzigen Nuance als auch in voneinander verschiedenen Nuancen zu bedrucken. Erfolgt das Bedrucken in einer Nuance, so kann das Bedrucken des Fasermaterials ganzflächig oder auch mit einem Muster erfolgen. Hierzu reicht naturgemäss die Verwendung einer einzigen Tinte; die gewünschte Nuance kann jedoch auch durch den Druck mit mehreren Tinten mit voneinander verschiedenen Nuancen erstellt werden. Soll ein Druck auf dem Fasermaterial erstellt werden, welcher mehrere voneinander verschiedene Nuancen aufweist, so erfolgt das Bedrucken des Fasermaterials mit mehreren Tinten, welche jeweils die gewünschte Nuance aufweisen oder so gedruckt werden, dass die jeweilige Nuance erstellt wird (z.B. dadurch, dass Tinten mit verschiedenen Nuancen übereinander auf das Fasermaterial gedruckt werden und so die zu erzielende Nuance ergeben).Ink-jet printing as well as subsequent drying and fixing can also be carried out in a single step. This means in particular that these steps are carried out continuously. This means that devices for ink-jet printing, drying and fixing are installed one behind the other, through which the fiber material to be printed is continuously moved. The devices for ink-jet printing, drying and fixing can also be combined in a single machine. The fiber material is continuously transported through this machine and is then finished after leaving this machine. Drying can take place, for example, by means of thermal energy (as indicated above, for example) or in particular by means of infrared radiation (IR). The fixation can take place, for example, by means of ultraviolet radiation (UV) or by means of thermal energy (as indicated above, for example). Of course, ink-jet printing can also be carried out separately, and drying and fixing are carried out continuously, for example in a single machine, as indicated above. With the printing processes mentioned above, it is possible to print the fiber materials both in a single shade and in different shades. If the printing is done in one shade, the printing of the fiber material can take place over the whole area or with a pattern. The use of a single ink is naturally sufficient for this; however, the desired shade can also be created by printing with several inks with different shades. If a print is to be made on the fiber material, which has several different shades, then the fiber material is printed with several inks, each of which has the desired shade or is printed in such a way that the respective shade is created (for example by using inks with different nuances are printed on top of each other on the fiber material and thus result in the nuance to be achieved).
Ferner ist es möglich, ein flächiges Fasermaterial beidseitig zu bedrucken. Hierbei kann z.B. eine Seite des Fasermaterials in einer Nuance bedruckt werden, z.B. ganzflächig, und die andere Seite des Fasermaterials wird mit einem Muster in einer oder mehreren voneinander verschiedenen Nuancen bedruckt. Selbstverständlich kann prinzipiell diese Seite auch ebenfalls ganzflächig in einer Nuance bedruckt werden. Ein solches Verfahren kann z.B. so ausgeführt werden, dass an jeder Seite des zu bedruckenden flächigen Fasermaterials einer oder mehrere Druckköpfe vorhanden sind. Es werden dann beide Seiten des Fasermaterials gleichzeitig bedruckt. Die Druckköpfe der jeweiligen Seite des Fasermaterials können sich direkt gegenüberstehen oder auch seitlich versetzt voneinander installiert sein. Ueblicherweise wird das Fasermaterial zwischen diesen Druckköpfen hindurch bewegt. Mit dieser Ausführungsform lassen sich interessante Effekte erzielen, welche sich insbesondere beim Umschlagen des flächigen Fasermaterials erkennen lassen.It is also possible to print a flat fiber material on both sides. Here, e.g. one side of the fiber material is printed in one shade, e.g. all over, and the other side of the fiber material is printed with a pattern in one or more different shades. In principle, of course, this page can also be printed on the entire surface in one shade. Such a method can e.g. are designed so that one or more print heads are present on each side of the flat fiber material to be printed. Both sides of the fiber material are then printed simultaneously. The print heads on the respective side of the fiber material can face each other directly or can be installed laterally offset from one another. Usually the fiber material is moved between these printheads. With this embodiment, interesting effects can be achieved, which can be seen in particular when the flat fiber material is turned over.
Eine weitere interessante Ausführungsform betrifft das sogenannte Imaging. Hierbei wird eine Vorlage, d.h. ein Bild welches mit dem Druck nachgestellt werden soll, digitalisiert, z.B. mittels einer Videokamera oder einem Scanner. Das digitalisierte Bild wird auf einen Computer übertragen, welcher dann mittels eines Ink-Jet Druckers das Bild auf das Fasermaterial druckt. Selbstverständlich kann das digitalisierte Bild auch bereits in dem Computer gespeichert sein, so dass die Digitalisierung entfällt. So kann ein zu druckendes Bild z.B. am Computer mit Graphik-Software erstellt worden sein. Bei dem zu druckenden Bild kann es sich z.B. auch um Buchstaben, Zahlen, Wörter, jegliche Muster oder auch
komplexe verschiedenfarbige Bilder handeln. Verschiedenfarbige Bilder können z.B. durch Verwendung von mehreren Tinten mit voneinander verschiedenen Nuancen erstellt werden.Another interesting embodiment relates to the so-called imaging. Here, a template, ie an image that is to be reproduced with the print, is digitized, for example using a video camera or a scanner. The digitized image is transferred to a computer, which then prints the image on the fiber material using an ink-jet printer. Of course, the digitized image can also already be stored in the computer, so that digitization is not necessary. For example, an image to be printed could have been created on the computer with graphics software. The image to be printed can also be letters, numbers, words, any pattern, for example deal with complex, different-colored images. Images in different colors can be created, for example, by using several inks with different shades.

Die verwendeten Drucktinten zeichnen sich durch gute Stabilität und gute Viskositätseigenschaften aus.The prints obtainable by the process according to the invention have good general fastness properties; e.g. they have good light fastness, good wet fastness, such as water, wash, sea water, over-dyeing and sweat fastness, good chlorine fastness, rubbing fastness, fastness to ironing and pleating fastness as well as sharp contours and a high color strength. The printing inks used are characterized by good stability and good viscosity properties.
