Sie mag zwar bisherige Nachteile der zum Stand der Technik dieser technischen Lehre gehörenden Handlungsanleitungen und Mittel abstellen, vermag jedoch auch nicht die Probleme zu lösen, die mit dem Vorliegen von gefährlichen Arbeitsstoffen - insbesondere schwefelhaltige Reduktionsmittel - in Bezug auf Mensch, Umwelt und Anlagen verbunden sind. But the technical teaching according to DE 196 29 453 A1 also works reductive cleaning systems. She likes previous disadvantages of belonging to the prior art of this technical teaching Switch off instructions for action and means, but neither can Solve problems with the presence of hazardous materials - especially sulfur-containing reducing agents - in relation to humans, Environment and facilities are connected.
Von diesen Mängeln des Standes der Technik und deren Ursachen ausgehend, liegt der Erfindung die Aufgabe zu Grunde, ein einfaches und kostengünstiges Verfahren und Mittel zur Durchführung des Verfahrens zur Nachreinigung von gefärbten und/oder bedruckten polyesterhaltigen, textilen Produkten bereitzustellen, welches bzw. welche ohne schwefelhaltige Reduktionsmittel auskommt(en), auf allen Anlagen problemlos, insofern auch ungefährlich, einsetzbar sind, ohne daß oxidative Zersetzungen wie z. B. bei Hydrosulfit zu befürchten sind, möglichst in ihrem Anwendungsbereich umfänglicher und umweltverträglicher ist/sind.Of these deficiencies in the prior art and their causes starting from, the invention is based on the object, a simple and inexpensive method and means for performing the method for Post-cleaning of dyed and / or printed polyester-containing textiles To provide products which or which without sulfur Reducing agent (s) can be used without problems on all systems, so too are harmless, can be used without oxidative decomposition such. B. at Hydrosulfite are to be feared, if possible in their area of application is / are more extensive and environmentally compatible.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine oxidative Nachreinigung unter Einsatz eines Oxydationsmittels der Formel MeIBO3.4H2O, wobei Me = einwertiges Metall oder NH4 darstellt, und eines Dispergators vom Typ ethoxylierte Fettsäure oder Alkylarylsulfonat, vorzugsweise im alkalischen Medium, insbesondere unter Einsatz von Natronlauge, bei Temperaturen zwischen 40°C und 140°C, insbesondere aber bei 80°C über eine Zeitdauer von 5 min bis 120 min, insbesondere bei 20 min vorgenommen wird. Für MeIBO3.4H2O läßt sich beispielsweise vorteilhaft Natriumperborat-tetrahydrat einsetzen. Natürlich sind alle weiteren denkbaren oxidierend wirkenden Mittel einsetzbar. Als Dispergiermittel auf Basis ethoxylierter Fettsäuren läßt sich z. B. vorteilhaft eine Fettsäureethoxylat- Zubereitung, die unter dem Markennamen SETAVIN PE® bekannt und erhältlich ist, einsetzen. Als Dispergiermittel auf Basis Alkylarylsulfonat läßt sich z. B. Zetesan PD® einsetzen.According to the invention, this object is achieved in that an oxidative after-cleaning using an oxidizing agent of the formula Me I BO 3 .4H 2 O, where Me = monovalent metal or NH 4 , and a dispersant of the ethoxylated fatty acid or alkylarylsulfonate type, preferably in an alkaline medium , in particular using sodium hydroxide solution, at temperatures between 40 ° C. and 140 ° C., but in particular at 80 ° C. over a period of 5 minutes to 120 minutes, in particular at 20 minutes. Sodium perborate tetrahydrate, for example, can advantageously be used for Me I BO 3 .4H 2 O. Of course, all other conceivable oxidizing agents can be used. As a dispersant based on ethoxylated fatty acids such. B. advantageous to use a fatty acid ethoxylate preparation, which is known and available under the brand name SETAVIN PE®. As a dispersant based on alkylarylsulfonate, z. B. Use Zetesan PD®.
In der Fachwelt war bisher ausnahmslos angenommen worden, daß eine
Nachreinigung von polyesterhaltigen Textilien nach ihrem Färbe- oder
Druckvorgang nur in reduktiver Verfahrensführung bzw. mit reduktiv wirkenden
Mitteln möglich ist. Es wurde demgegenüber aber überraschenderweise
gefunden, daß außer der reduktiven Verfahrensführung der
Nachreinigung/Nachwaschung eine solche auch auf oxidativem Wege möglich
ist. Folgende vorteilhafte Wirkungen sind mit solch einer oxidativen
Verfahrensführung bzw. mit dem Einsatz eines oxidativ wirkenden
Nachreinigungsmittels erreichbar:
In the professional world, it was previously assumed without exception that post-cleaning of polyester-containing textiles after their dyeing or printing process is only possible in a reductive process or with reductive agents. On the other hand, it was surprisingly found that in addition to the reductive process of post-cleaning / post-washing, this is also possible by oxidative means. The following advantageous effects can be achieved with such an oxidative procedure or with the use of an oxidative after-cleaning agent:
- - Es sind keine schwefelhaltigen Reduktionsmittel mehr nötig; insbesondere betrifft dies das allgemein übliche Reduktionsmittel Hydrosulfit (Natriumdi thionit, Na2S2O4) welches- No more sulfur-containing reducing agents are required; in particular, this relates to the commonly used reducing agent hydrosulfite (sodium di thionite, Na 2 S 2 O 4 ) which
- - stark staubt, damit die Schleimhäute reizt,- very dusty, so that the mucous membranes are irritated,
- - selbstentzündlich ist, vor allem in Verbindung mit Befeuchten durch Wasser,- is self-igniting, especially in connection with moistening Water,
- - stark geruchsbildend ist, da bei der reduktiven Nachreinigung Schwefelwasserstoff entsteht,- is strongly odor-forming, since in the reductive post-cleaning Hydrogen sulfide is produced
- - als Reaktionsprodukte Sulfid und Sulfit bildet, die das Abwasser stark belasten (CSB) und als stark gewässertoxisch gelten,- As reaction products forms sulfide and sulfite, which the wastewater strong pollute (COD) and are considered to be highly toxic to water,
wodurch gefährliche Arbeitsstoffe ersetzt werdenthereby replacing hazardous substances
Die ansonsten alternativ eingesetzten Sulfinat-Verbindungen sind allgemein
sehr teuer und werden wenig verwendet; darüber hinaus sind sie
lichtempfindlich
The sulfinate compounds which are otherwise used as an alternative are generally very expensive and are used little; they are also sensitive to light
- - Die durch diese technische Lehre vorgeschlagenen Oxidationsmittel sind stabil, nicht lichtempfindlich und nicht entzündlich.- The oxidizing agents suggested by this technical teaching are stable, not sensitive to light and not flammable.
- - Diese vorgeschlagenen Oxidationsmittel ermöglichen eine bessere jedoch mindest gleiche Oligomerentfernung als dies mit Hydrosulfit möglich ist.- These proposed oxidants allow a better one, however at least the same oligomer removal as is possible with hydrosulfite.
- - Die vorgeschlagene Mischung ermöglicht bei der vorgeschlagenen Verfahrensdurchführung das problemlose Einsetzen auf allen Aggregaten, da keine oxidative Zersetzung wie bei Hydrosulfit erfolgt.- The proposed mixture enables the proposed Process implementation, problem-free use on all units, since there is no oxidative decomposition as with hydrosulfite.
- - Es kann ein absolut geruchsfreier Nachreinigungsprozeß gewährleistet werden.- An absolutely odorless post-cleaning process can be guaranteed become.
- - Es entstehen deutlich weniger Abwasserbelastungen; der CSB-Wert des Wassers wird verbessert. - There are significantly less wastewater pollution; the COD value of the Water is improved.
- - Die Reinigungskraft ist mindestens gleichwertig, was die diesbezüglichen Prüfungen belegen.- The cleaning power is at least equivalent to what the related Take exams.
- - Es sind gleichwertige Nichtbeeinflussungen der erzielten Färbungen durch Echtheitsvergleiche und des Warengriffes nachgewiesen.- There are equivalent non-effects on the colorations achieved Authenticity comparisons and the goods handle proven.
- - Die eingesetzten Dispergiermittel auf Basis Fettsäureethoxylat sind biologisch abbaubar und basieren auf nachwachsenden Rohstoffen.- The dispersants used are based on fatty acid ethoxylate biodegradable and based on renewable raw materials.
- - Diese technische Lehre ist für anthrachinoide und indigoide Dispersionsfarbstoffe geeignet.- This technical teaching is for anthrachinoid and indigoide Disperse dyes suitable.
An nachfolgenden, ausgewählten Ausführungsbeispielen soll die Erfindung näher erläutert werden, wobei sich hier dem Fachmann zeigt, daß es entgegen der bisherigen Fachmeinung durchaus möglich ist, an Stelle der bisher ausschließlich reduktiv wirkenden Nachreinigungsverfahren und Nachbehandlungsmittel oxydativ geführte Nachreinigungsverfahren nach dem Färben und/oder Bedrucken von polyesterhaltigen textilen Produkten einschließlich solcher Mittel zur Durchführung des Verfahrens einzusetzen.The invention is intended to be based on the following selected exemplary embodiments are explained in more detail, with the person skilled in the art showing that this is contrary the previous expert opinion is quite possible instead of the previous one only reductive cleaning processes and Aftertreatment oxidative after cleaning procedure after the Dyeing and / or printing of textile products containing polyester including such means to implement the procedure.
