Die Erfindung betrifft ein Verfahren zum Ablösen von Polyester-Oligomeren-Ablagerungen in Färbeapparaturen durch Enzyme.The invention relates to a method to peel off of polyester oligomer deposits in dyeing machines through enzymes.
Bei der Herstellung von Polyethylenglykolterephthalat entsteht eine Reihe von niedermolekularen Produkten, die man üblicherweise unter dem Begriff Oligomere zusammenfaßt. Oligomere enthalten in ringförmiger oder linearer Anordnung die Grundbausteine des Polyesters. Sie liegen mit einer Menge von etwa 2 % (bzgl. Faser) vor, der weitaus größte Anteil davon ist cyclisches Trimer.In the production of polyethylene glycol terephthalate creates a series of low molecular weight products that are commonly used summarized under the term oligomers. Oligomers contain in annular or linear arrangement the basic building blocks of the polyester. they lay with an amount of about 2% (in terms of fiber), by far the largest proportion of which is cyclic trimer.
Die Bildung der Oligomeren läßt sich bei der Granulat-Herstellung und -verarbeitung nicht vermeiden. Unter den Bedingungen der Textilveredlung treten die kleinen Polyester-Moleküle auf Grund ihrer relativ hohen Konzentration aus der Faser aus. Ein Teil der Oligomere verbleibt an der Faseroberfläche in Form von festsitzendem Belag, ein anderer Teil wandert in die Flotte und kristallisiert dann an geeigneten Stellen aus; die gefürchteten Ablagerungen entstehen. Das Konzentrations-Verhältnis zwischen den an der Faseroberfläche festsitzenden Oligomeren und den lose abgelagerten Oligomeren (die in die Flotte austreten können) hängt sowohl von der Faserstruktur bzw. deren Verarbeitungsbedingungen als auch von den Färbeparametern ab.The formation of the oligomers can be in the production of granules and avoid processing. Under the conditions of textile finishing the small polyester molecules come to the bottom their relatively high concentration from the fiber. A part of Oligomers remain on the fiber surface in the form of stuck Base, another part migrates into the fleet and crystallizes then from appropriate places; the dreaded deposits arise. The concentration ratio between those on the fiber surface stuck oligomers and the loosely deposited oligomers (the can leave the fleet) depends on both of the fiber structure and its processing conditions as well as the coloring parameters from.
Bei der Weiterverarbeitung der Polyethylenterephthalat-Fasern bereitet vor allem das cyclische Trimere auf Grund seiner geringen Löslichkeit große Probleme:
- – Abrieb und Verschleiß an Fadenführungselementen, verbunden mit Faserschädigungen, in verschiedenen textilen Verarbeitungsstufen (Verspinnen, Wirken, Weben)
- – Ablagerung von schwerlöslichen Niederschlägen in Färbegeräten (Verschmutzung, Verschlechterung des Warenlaufes, Verringerung des Wärmeübergangs an Heizelementen) [1–9].
- - Abrasion and wear on thread guide elements, combined with fiber damage, in various textile processing stages (spinning, knitting, weaving)
- - Deposition of poorly soluble precipitates in dyeing devices (contamination, deterioration in the flow of goods, reduction of heat transfer on heating elements) [1–9].
Im Unterschied zu Oligomeren von Polyamid können Oligomere des Polyesters, die auf der Faseroberfläche auskristallisiert sind, nicht abgewaschen werden [10]. Ebenso führten Versuche zum Auswaschen der Oligomere aus dem Granulat nicht zu verwertbaren Ergebnissen. Nach [7] bringen auch andere Ansätze zur Entfernung der Ablagerungen keinen Durchbruch. So wird beim Spülen der Ware nur der lose angelagerte Anteil an Oligomeren entfernt. Auch Lösungsmittelvorbehandlungen [11] beseitigen die Probleme nicht. Hilfsmittelzusätze können den Austritt der Oligomeren nicht verhindern, sondern bestenfalls (durch Verkleben) das nachfolgende Stauben reduzieren. Heißablassen der Flotte [12] hilft nicht, da die Flottenkonzentration der Oligomere sehr gering ist und mit Hilfe von Dispergiermittel auch nicht erhöht werden kann. Reduktionsmittel beeinflussen die Oligomerenauflage nicht, lediglich eine intensive Alkalibehandlung führt über das Abschälen der Oberfläche zu einem spürbaren Effekt.In contrast to oligomers from Polyamide can Oligomers of polyester that crystallize on the fiber surface are not washed off [10]. Attempts to wash out also led of the oligomers from the granules are not usable results. According to [7], there are other approaches no breakthrough to remove the deposits. So at do the washing up only the loosely stored portion of oligomers is removed from the goods. Also solvent pretreatments [11] don't solve the problems. Aid additives can Do not prevent the oligomers from escaping, but at best (through Bonding) reduce the subsequent dusting. hot draining the liquor [12] does not help because the liquor concentration of the oligomers is very low and cannot be increased with the help of dispersants can. Reducing agents do not affect the oligomer coating, only an intensive alkali treatment leads to the peeling of the surface to a noticeable Effect.
In [7, 13] wird als Lösung der angedeuteten Probleme vorgeschlagen, die cyclischen Trimere noch vor dem Kristallisieren durch Hydrolyse zu zerstören. Dazu soll vor der eigentlichen Veredlungsstufe eine alkalische Vorbehandlung bei hoher Temperatur durchgeführt und dann – wegen der Wirtschaftlichkeit im gleichen Bad – die Flotte auf Färbebedingungen umgestellt werden; wichtig sei auch eine intensive Strömungsgeschwindigkeit. Nachteilig ist hierbei die wiederholte Einbindung zusätzlicher Prozeßschritte, die viel Zeit und Energie beanspruchen.In [7, 13] the solution is problems suggested, the cyclic trimers still before crystallization by hydrolysis. To do this, before the actual Refinement stage an alkaline pretreatment at high temperature carried out and then - because of economy in the same bathroom - the fleet on dyeing conditions be converted; Intensive flow velocity is also important. The disadvantage here is the repeated integration of additional Process steps, that take a lot of time and energy.
Auch Ansätze zur Produktion mit Fasern von vermindertem Gehalt an cyclischem Trimer wurden bekannt, eine vollständige Vermeidung von Oligomeren scheint jedoch nicht möglich (z.B. [13, 14]).Also approaches to production with fibers of reduced cyclic trimer content have been known, a full Avoiding oligomers does not seem to be possible (e.g. [13, 14]).
Zusammenfassend ist festzuhalten, dass keine der vorgeschlagenen Lösungen den Durchbruch zu einer weitgehend oligomerenfreien Faser oder zu einer Veredlungstechnologie, die die Ablagerungen von Oligomeren verhindert, brachten. Man erkennt das auch an den Empfehlungen der Hersteller von Polyester-Färbemaschinen. Diese Empfehlungen beinhalten Prozeduren wie alkalisches Auskochen mit hohen NaOH-Konzentrationen bei Temperaturen von 130°C oder den Einsatz spezieller kationischer Tenside, ebenfalls im alkalischen Bereich, bei ähnlichen Bedingungen [10].In summary it should be noted that none of the proposed solutions the breakthrough to a largely oligomer-free fiber or a finishing technology that removes the deposits of oligomers prevented brought. You can also see this from the recommendations of the Manufacturer of polyester dyeing machines. These recommendations include procedures such as alkaline decoction with high NaOH concentrations at temperatures of 130 ° C or Use of special cationic surfactants, also in alkaline Area, at similar Conditions [10].
Die bis heute andauernden Forschungsaktivitäten bestätigen die Permanenz der Oligomeren-Problematik.The ongoing research activities confirm this Persistence of the oligomer problem.
Ziel der Erfindung ist ein Verfahren zum Ablösen von Polyester-Oligomeren-Ablagerungen in Färbeapparaturen. The aim of the invention is a Removal procedure of polyester oligomer deposits in dyeing machines.
Diese Aufgabe wird erfinderisch dadurch gelöst, dass die Oligomeren mit Enzymen, die die Hydrolyse von Estergruppen katalysieren, in eine ablösbare Form gebracht werden.This task becomes inventive solved, that the oligomers with enzymes that hydrolysis of ester groups catalyze into a removable Be brought into shape.
Enzym-Technologien haben sich in der Textilveredlung etabliert. Bei der Ausrüstung von Baumwolle und Lyocell sind sie technischer Standard, bei Wolle werden entsprechende Verfahren vorbereitet. Die Übertragung auf Veredlungsprozesse von Polyester ist damit eine logische Fortsetzung dieser Entwicklung.Enzyme technologies have become popular of textile finishing established. When finishing cotton and lyocell they are the technical standard, with wool there are corresponding processes prepared. The transfer a logical continuation of polyester finishing processes this development.
Die Ablösung von Oligomeren-Ablagerungen in Färbeapparaturen hat verschiedene Vorteile:
- – die Prozesse laufen bei niedrigen Temperaturen ab,
- – im Gegensatz zum bisher üblichen alkalischen Auskochen belasten die enzymatischen Verfahren nicht die metallischen Materialien der Färbeapparaturen,
- – es entstehen keine Abwässer mit toxischen Inhaltsstoffen.
- - The processes run at low temperatures from,
- - in contrast to the alkaline boil-out that has been customary up to now, the enzymatic processes do not burden the metallic materials of the dyeing apparatus,
- - There is no waste water with toxic ingredients.
In [15] wird über den Einsatz ausgewählter Lipasen die Hydrophilie von Polyesterfasern verbessert. Nach US Patent 5,997,584 läßt sich mittels Esterasen das Pillingverhalten von Polyestergewebe verbessern. Zur Behandlung von Oligomeren mittels Estergruppenspaltender Enzyme liegen bisher keine Arbeiten vor.In [15] is about the use of selected lipases improves the hydrophilicity of polyester fibers. According to U.S. Patent 5,997,584 let yourself improve the pilling behavior of polyester fabric using esterases. For the treatment of oligomers using enzymes that cleave ester groups no work has been done so far.
Für die chemische Spaltung der Oligomeren sind spezielle Enzymen, die die Hydrolyse von Estergruppen katalysieren, notwendig. Es handelt sich dabei um die Klasse der Carboxylesterhydrolasen (EC 3.1.1, z.B. Carboxylesterasen und Lipasen). Lipasen sind insbesondere wegen ihrer Fähigkeit, die Hydrolyse von wasserunlöslichen Substraten zu katalysieren, von besonderer Bedeutung. Weiterhin eignen sich auch auf Grund von spezifischen Nebenaktivitäten einige Peptidasen (EC 3.4, z.B. Serinpeptidasen).For the chemical cleavage of the oligomers are special enzymes that catalyze the hydrolysis of ester groups. It deals the class of carboxyl ester hydrolases (EC 3.1.1, e.g. Carboxylesterases and lipases). Lipases are especially because of their ability the hydrolysis of water-insoluble Catalyzing substrates is of particular importance. Farther some are also suitable due to specific side activities Peptidases (EC 3.4, e.g. serine peptidases).
Enzyme dieser Klassen sind in der Lage, die sich ablagernden Polyester-Oligomere partiell zu hydrolysieren. Es entstehen niedermolekulare Spaltprodukte, die löslich bzw. dispergierbar sind. Die Spaltprodukte können dann zusammen mit der Färbeflotte die Apparatur verlassen. Ablagerungen werden somit wirkungsvoll entfernt.Enzymes of these classes are in the Able to partially hydrolyze the deposited polyester oligomers. Low-molecular cleavage products are formed which are soluble or are dispersible. The fission products can then together with the dyeing liquor leave the apparatus. Deposits are therefore effective away.
