Description

Verfahren zum Färben von cellulosehaltigem Textilmaterial durch IndigoProcess for dyeing cellulosic textile material by indigo
Die vorliegende Erfindung beschreibt ein Verfahren zum Färben von cellulose¬ haltigem Textilmaterial durch Indigo, wobei das Indigo in nicht reduzierter Form durch Sublimation/Verdampfung in die Gasphase überführt wird und sich an¬ schließend auf dem textilen Substrat abscheidet.The present invention describes a method for dyeing cellulose¬ containing textile material by indigo, wherein the indigo is transferred in unreduced form by sublimation / evaporation in the gas phase and then closing on the textile substrate deposited.
Das Färben von cellulosehaltigem Textilmaterial durch Indigo ist seit langem bekannt. Um dem wasserunlöslichen Indigo die erforderliche Substanztivität zu verleihen, d.h. um das Indigo auf einem Textilmaterial zu fixieren, muss dieser zunächst durch Reduktion in eine wasserlösliche Form überführt werden und anschließend durch Oxidation zum entsprechenden Farbpigment oxidiert zu werden um so auf der Faser fixiert zu werden.The dyeing of cellulosic textile material by indigo has been known for a long time. In order to give the water-insoluble indigo the required substance-efficiency, i. In order to fix the indigo on a textile material, it must first be converted by reduction into a water-soluble form and then oxidized by oxidation to the corresponding color pigment so as to be fixed on the fiber.
Die meisten Küpenfarbstoffe zeichnen sich durch eine hohe Affinität zur Faser aus, dieses trifft jedoch nicht für Indigo zu. Wegen dieser niedrigen Affinität von Indigo zur Faser sind die kontinuierlichen sowie die diskontinuierlichen Verfah- ren (Färben aus dem Bad) sowohl aus wirtschaftlicher wie auch aus ökologi¬ scher Hinsicht problematisch und aufwendig. Die deutsche Patentanmeldung DE 44 06 785 und 196 28 806 beschreiben diskontinuierliche bzw. kontinuierli¬ che Verfahren um diese niedrige Affinität, bzw. Substantivität des Indigos zu er¬ höhen. Nachteilig bei dem diskontontinuierlichen Verfahren erweist sich jedoch die Tatsache, dass aufgrund der spezifischen Eigenschaft des Indigos, wie zum Beispiel Küpenhautbildung, stets eine ungleichmäßige und fleckige Färbung aus wässrigem Medium erhalten wird. Bei den kontinuierlichen Verfahren sind die dazu verwendeten Färbeanlagen sehr groß und kostenintensiv. Ca 90% des Indigos werden heute nach dem kontinuierlichen Verfahren meist mit 5-6 Tauchküpen (Farbbädern) und jeweiliger Zwischenoxidation in der Luft verar¬ beitet. Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zur Färbung von cellulosehaltigem Textilmaterial durch Indigo bereitzustellen, wobei Indigo in seiner unreduzierten Form durch Sublimation/Verdampfung in die Gasphase überführt wird und sich anschließend auf dem Textilmaterial abscheidet.Most vat dyes are characterized by a high affinity for the fiber, but this is not true for indigo. Because of this low affinity of indigo for the fiber, both the continuous and the discontinuous processes (dyeing from the bath) are problematic and expensive both from an economic and ecological point of view. The German patent applications DE 44 06 785 and 196 28 806 describe discontinuous or continuous processes in order to increase this low affinity or substantivity of the indigo. A disadvantage of the discontinuous process, however, is the fact that due to the specific nature of the indigo, such as, for example, vascular skin formation, an uneven and patchy staining is always obtained from an aqueous medium. In continuous processes, the dyeing units used for this purpose are very large and cost-intensive. About 90% of the indigo is processed by the continuous process usually with 5-6 immersion vats (dye baths) and respective intermediate oxidation in the air verar¬. The invention is therefore based on the object to provide a process for dyeing cellulose-containing textile material by indigo, wherein indigo is transferred in its unreduced form by sublimation / evaporation in the gas phase and then deposited on the textile material.
Die mit der Erfindung erzielten Vorteile bestehen darin, dass die Steuerung der zu übertragenden Indigomenge durch Einstellung der von der Energiequelle ab¬ gegebenen Energie leicht möglich ist. Zudem ist der apparative Aufwand im Vergleich zu dem üblicherweise eingesetzten kontinuierlichen Verfahren gering, da nicht eine Vielzahl von Färbebädem und Luftgängen benötigt werden. Auch gestattet das erfindungsgemäße Verfahren eine direkte Färbung ohne vorher¬ gehende Reduktion und anschließende Reoxidation des lndigos.The advantages achieved by the invention are that the control of the amount of indigo to be transferred by adjusting the ab¬ given by the energy source energy is easily possible. In addition, the expenditure on equipment compared to the continuous process commonly used is low, since not a variety of Därbebädem and air passages are needed. The process according to the invention also permits direct dyeing without previous reduction and subsequent reoxidation of the ligand.
Zur Lösung der gestellten Aufgabe sieht die Erfindung vor, dass Indigo in einem bestimmten Abstand vom Textilmaterial in die gasförmige Phase durch Subli¬ mation/Verdampfung überführt wird, sich anschließend auf dem textilen Sub¬ strat abscheidet und so auf der Faser fest fixiert wird.To achieve the object, the invention provides that indigo is transferred at a certain distance from the textile material into the gaseous phase by sublimation / evaporation, then it is deposited on the textile substrate and thus firmly fixed on the fiber.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 und folgende näher angegeben. Die Weiterbildung nach Patentanspruch 2 ermög¬ licht es, dass es sich bei dem eingesetzten cellulosehaltigen Textilmaterial um Garn, Gewebe, Strick- und Wirkwaren handelt; ein besonders bevorzugtes Tex¬ tilmaterial ist hierbei Garn aus Cellulosefasem, welches nachfolgend zu Denim bzw. Jeans weiterverarbeitet wird. Nach Patentanspruch 3 ist es zudem mög- lieh, dass die Sublimation/Verdampfung des unreduzierten lndigos durch Ein¬ wirkungen von thermischer Energie in Form von Kontakthitzeübertragung und/oder Verwirbelung mit heißer Luft oder durch Einwirkung von Strahlung auf das Indigo erfolgen kann. Nach Patentanspruch 4 ist es in einer vorteilhaften Ausgestaltung möglich, dass das sublimierte/verdampfte Indigo durch einen gerichteten Luftstrom in Richtung des Textilmaterials getragen wird. Dieser ge¬ richtete Luftstrom kann entsprechend Patentanspruch 5 durch einen Vakuum¬ strom verstärkt werden. Weiter ist es möglich, dass entsprechend Patentan¬ spruch 6 der Luftstrom durch das Textilmaterial geführt wird. Nach Patentan- spruch 7 ist es weiter möglich, dass das eingefärbte Textilmaterial gewaschen und geseift wird, um nicht fixierte Indigoanteile zu entfernen. Zudem ist es ent¬ sprechend Patentanspruch 8 möglich, die Sublimation/Verdampfung des Indi- gos durch Verwendung von Vakuum gezielt zu steuern. Advantageous embodiments of the invention are specified in the claims 2 and following. The development according to claim 2 makes it possible that the cellulosic textile material used is yarn, woven fabric, knit and knitwear; A particularly preferred textile material here is yarn made of cellulose fibers, which is subsequently processed further into denim or jeans. According to claim 3, it is also possible that the sublimation / evaporation of the unreduced ligand can be effected by the action of thermal energy in the form of contact heat transfer and / or turbulence with hot air or by exposure to indigo. According to claim 4, it is possible in an advantageous embodiment that the sublimated / vaporized indigo is carried by a directed air flow in the direction of the textile material.
