Mittel und Verfahren zum Entgiften von textilen Produkten und Waschflotten  Means and methods for detoxifying textile products and wash liquors

Beschreibung description

Die Erfindung betrifft ein Mittel und ein Verfahren zum Entgiften von textilen Produkten und der Waschflotte, wie sie bei dem Waschen und Reinigen von textilen Produkten anfällt. The invention relates to an agent and a method for detoxifying textile products and the wash liquor, as obtained in the washing and cleaning of textile products.

Beim Waschen von textilen Produkten wird ein Waschwasser, auch oft When washing textile products is a wash water, too often

Waschflotte genannt, die im allgemeinen Reinigungsmittel wie Seife, Called wash liquor, which is generally detergents such as soap,

Detergentien und dgl. sowie Waschhilfsmittel wie Bleichmittel, Detergents and the like, and washing aids, such as bleaches,

Ausrüstungsmittel usw. enthält, verwendet. Bisweilen kann auch Wasser ohne besondere Zusätze eingesetzt werden. Equipment, etc. contains used. Sometimes water can be used without special additives.

Insbesondere bei fabrikneuen Textilien weist das Waschwasser meist auch noch zum Teil toxische und häufig allergieauslösende und Especially with brand new textiles, the washing water usually also partly toxic and often allergiauslösende and

gesundheitsgefährdende Substanzen auf, die vom textilen Produkt stammen. harmful substances originating from the textile product.

Diese giftigen Stoffe verbleiben nach dem Waschvorgang in mehr oder weniger großen Spuren auf den textilen Produkten und sind selbstverständlich auch in der abzuführenden Waschflotte vorhanden. Dadurch gelangen dann diese Schadstoffe direkt in kommunale Abwasserreinigungsanlagen, wo sie dann größtenteils, da wasserlöslich, ungehindert im gereinigten Abflußstrom der These toxic substances remain after the washing process in more or less major traces on the textile products and are of course also present in the discharged liquor. As a result, these pollutants then go directly into municipal wastewater treatment plants, where they then largely, since water-soluble, unhindered in the purified effluent stream

BESTÄTIGUNGSKOPtE Kläranlagen in das offene Wassersystem gelangen und sich letztlich in unserem Trinkwasser wiederfinden können. BESTÄTIGUNGSKOPtE Wastewater treatment plants can enter the open water system and ultimately find themselves in our drinking water.

Es besteht deshalb ein Bedürfnis nach Mitteln und Verfahren, mit denen es möglich ist, ein von schädlichen und gesundheitsgefährdenden Stoffen befreites textiles Produkt zu erhalten, und wobei auch eine Waschflotte entsteht, die von diesen Schadstoffen befreit ist, so daß diese bedenkenlos in die kommunalen Abwasserreinigungsanlagen eingeleitet werden kann. Es ist deshalb sehr wünschenswert, die potentiell gesundheitsgefährdenden There is therefore a need for means and methods by which it is possible to obtain a liberated from harmful and harmful substances textile product, and also a wash liquor is created which is free of these pollutants, so that they safely in the municipal wastewater treatment plants can be initiated. It is therefore very desirable, the potentially harmful

Substanzen, die während des gesamten Herstellungsprozess von textilen Produkten zum Einsatz kommen und sich teilweise noch auf dem textilen Produkt befinden, zu binden und so permanent zu entfernen, sobald sie sich in der Waschflotte befinden, um eine Re-Kontaminierung des textilen Produkts z.B. beim Abpumpen der Waschflotte zu verhindern. Substances that are used throughout the manufacturing process of textile products and are still partially on the textile product to bind and permanently remove as soon as they are in the wash liquor to re-contamination of the textile product, for. prevent when pumping the wash liquor.

Aufgabe der Erfindung ist es deshalb ein Mittel zur Verfügung zu stellen, das zum Entgiften von textilen Produkten und der Waschflotte dient, welche beim Waschen und Reinigen von textilen Produkten anfällt. The object of the invention is therefore to provide a means that is used to detoxify textile products and the wash liquor, which is obtained during washing and cleaning of textile products.

Aufgabe der Erfindung ist es ferner ein Verfahren zur Verfügung zu stellen, mit dem es möglich ist, ein entgiftetes Waschabwasser oder Waschflotte zu erhalten. Diese Aufgabe wird gelöst durch ein Mittel zum Entgiften von textilen Produkten und der Waschflotte, welche beim Waschen und Reinigen von textilen Produkten anfällt, das dadurch gekennzeichnet ist, dass das Mittel ein wasserunlösliches Behältnis umfasst, das Durchlässe für die Waschflotte aufweist und adsorbierende, absorbierende und Kationen und Anionen austauschende Granulate und/oder Pulver enthält, deren Durchmesser grösser als der Durchmesser der Durchlässe des Behältnisses ist. Diese Granulate und/oder Pulver weisen eine ausgeprägte Neigung zum Binden dieser The object of the invention is also to provide a method with which it is possible to obtain a detoxified washing wastewater or wash liquor. This object is achieved by a means for detoxifying textile products and the wash liquor, which is obtained during washing and cleaning of textile products, which is characterized in that the means comprises a water-insoluble container having passages for the wash liquor and adsorbent, absorbent and Cations and anions containing exchange granules and / or powder whose diameter is greater than the diameter of the passages of the container. These granules and / or powders have a pronounced tendency to bind them

Schadstoffe auf. Pollutants.

In einer vorteilhaften Ausführungsform der Erfindung besteht das Granulat oder das Pulver aus einem einheitlichen Material mit Schadstoffe In an advantageous embodiment of the invention, the granules or the powder of a uniform material with pollutants

In einer besonders vorteilhaften Ausführungsform der Erfindung enthält das Behältnis zusätzlich Substanzen, welche Schadstoffe in der Waschflotte in unschädliche Stoffe umwandeln. Diese Substanzen können daher auch wasserlöslich sein. In a particularly advantageous embodiment of the invention, the container additionally contains substances which pollutants in the wash liquor in convert harmless substances. These substances can therefore also be water-soluble.

Ein weiterer Gegenstand der Erfindung ist ein Verfahren zum Entgiften von textilen Produkten und der Waschflotte, welche beim Waschen und Reinigen von textilen Produkten anfällt, das dadurch gekennzeichnet ist, dass man die textilen Produkte in Gegenwart eines Mittels gemäß einem der Patentansprüche 1, 2, 3, 4 oder 5 mit der Waschflotte behandelt. Another object of the invention is a method for detoxifying textile products and the wash liquor, which is obtained during washing and cleaning of textile products, which is characterized in that the textile products in the presence of an agent according to one of the claims 1, 2, 3 , 4 or 5 treated with the wash liquor.

Unter textilen Produkten im Rahmen der Erfindung sind auch zu verstehen Fasern und Fäden natürlicher Art wie Baumwolle oder Seide und synthetischer Art z.B. Polyester oder Polyamide usw. By textile products within the scope of the invention are also to be understood fibers and threads of natural type such as cotton or silk and synthetic type, e.g. Polyester or polyamides etc.

Das erfindungsgemäße Mittel wird auch in den Patentansprüchen 1-5 und das erfindungsgemäße Verfahren in Anspruch 6 beschrieben. The agent according to the invention is also described in claims 1-5 and the process according to the invention in claim 6.

Natürliche Fasern und daraus hergestellte Produkte können noch Rückstände von Düngemitteln enthalten, die beim Pflanzenwachstum eingesetzt wurden. Dazu kommen, dies gilt auch für synthetische Produkte, Rückstände von Behandlungs- und Veredelungsmitteln. Denn auch nach einem Waschprozess können vielfach noch Reste von Schadstoffen auf dem textilen Produkt verbleiben . Natural fibers and products made from them may still contain residues of fertilizers used in plant growth. In addition, this also applies to synthetic products, residues of treatment and finishing agents. Because even after a washing process remains of pollutants can often remain on the textile product.

Die Liste der möglichen Schadstoffe, die noch auf den textilen Produkten anhaften und von den jeweiligen Herstellungsprozessen abhängen und auch bei der Lagerung und beim Transport sich ansammeln können, ist sehr umfänglich. Unter textilen Produkten im Rahmen der Erfindung sind ferner zu verstehen Garne, textile Flächengebilde wie Gewebe, Gewirke, Vliese und dgl., The list of possible pollutants, which still cling to the textile products and depend on the respective manufacturing processes and can also accumulate during storage and transport, is very extensive. Under textile products in the context of the invention are also to be understood yarns, fabrics such as fabrics, knitted fabrics, nonwovens and the like.,

insbesondere aber auch Bekleidungsstücke wie Anzüge, Mäntel, Hemden, Hosen, Unterwäsche, Sport- und Funktionskleidung aber auch andere but especially clothing such as suits, coats, shirts, pants, underwear, sports and functional clothing but also others

Gegenstände wie Decken, Gardinen, Windeln, Handtücher, Taschentücher, aber auch Berufsbekleidung, z.B. auch solche, die von Ärzten und Articles such as blankets, curtains, diapers, towels, handkerchiefs, but also work clothing, e.g. even those by doctors and

medizinischem Personal getragen werden, auch frisch gekaufte Waren, kurz um alles Produkte, die beim Reinigen noch Schadstoffe abgeben können. be worn by medical personnel, including freshly purchased goods, in short everything products that can still give off pollutants when cleaning.

Als absorbierende, adsorbierende und Ionen austauschende Granulate oder Pulver können vorteilhaft Granulate und Pulver aus folgenden Materialien dienen: Aktivkohle, organofunktionalisierte beta-Cyclodextrine, Ionenaustauscher, insbesondere solche, die Hohlräume zur Aufnahme von As absorbent, adsorbing and ion-exchanging granules or powders may advantageously granules and powders of the following materials are used: activated carbon, organofunctionalized beta-cyclodextrins, ion exchangers, especially those containing cavities for receiving

Schwermetallen aufweisen, Bentonite, Zeolithe, die so strukturiert sind, dass sie dazu neigen, Schadstoffe an sich zu binden, wie zum Beispiel Toxisorb der Firma Clariant, natürliche Zeolithe wie z.B. Klinoptiolith, modifizierte Heavy metals, bentonites, zeolites, which are structured to tend to bind to pollutants, such as Toxisorb from Clariant, natural zeolites, e.g. Clinoptiolite, modified

wasserunlöslich gemachte Gelatinen, Keratinen, Polysacchariden, oder Peptide, usw. Besonders geeignet sind auch Teilchen aus hochporösen Polymeren, insbesondere Polypropylen, Polyethylen, Polyamid, Polymilchsäuren mit einer sogenannten Accurel-Struktur. Diese besteht darin, dass die Polymere water insoluble gelatins, keratins, polysaccharides, or peptides, etc. Particularly suitable are particles of highly porous polymers, in particular polypropylene, polyethylene, polyamide, polylactic acids with a so-called Accurel structure. This is that the polymers

hohlkugelartige Strukturen aufweisen, wobei die Hohlräume mit kanalförmigen Röhren verbunden sind. Strukturen dieser Art sind dem Fachmann bekannt und z.B. beschrieben in Fachzeitschriften und diesbezüglichen Patenten der Firma Akzo Nobel NV. Zu den Schadstoffen, die beim Entgiften entfernt werden sollen, gehören u.a. Schwermetalle u.a auch als Ionen, Formaldehyd, Pestizide, Herbizide, having hollow spherical structures, wherein the cavities are connected to channel-shaped tubes. Structures of this type are known to the person skilled in the art and are described, for example, in specialist journals and related patents by Akzo Nobel NV. The pollutants to be removed during detoxification include, among others, heavy metals including ions, formaldehyde, pesticides, herbicides,

Insektizide, Farbstoffe, Imprägnierungsmittel, Antistatika, optische Aufheller, Epoxidharze, Desinfektionsmittel und Konservierungsmittel sowie generell Textilhilfsmittelreste, u.a. solche, die gesundheitsschädlich sind, Allergien hervorrufen sowie umweltbelastend sein können. Insecticides, dyes, impregnating agents, antistatic agents, optical brighteners, epoxy resins, disinfectants and preservatives, and generally textile auxiliaries, i.a. those that are harmful to health, cause allergies and can be harmful to the environment.

Entgiften im Sinne der Erfindung bedeutet auch Entfernung von störenden Substanzen, auch wenn diese nicht unbedingt einen giftigen Stoff darstellen. Detoxification within the meaning of the invention also means removal of interfering substances, even if they are not necessarily a toxic substance.

Behältnisse, welche Durchlässe aufweisen und in denen sich waschaktive Stoffe befinden, sind bereits bekannt und werden beispielsweise in den US PS 4914 165 und 4 532 722 erwähnt. Dabei dienen die Behältnisse aber stets dazu, Stoffe durch die Durchlässe an die Waschflotten abzugeben, um eine bessere Schmutzablösung des Waschgutes zu erreichen. Dies ist auch bei Mitteln gemäß der WO 2009/071296 AI der Fall. Containers which have passages and in which wash-active substances are present are already known and are mentioned, for example, in US Pat. Nos. 4,914,165 and 4,532,722. However, the containers are always used to deliver substances through the passages to the wash liquors in order to achieve a better soil removal of the laundry. This is also the case with agents according to WO 2009/071296 AI.

In der WO 2009/006395 wird ein Behältnis beschrieben, das sogenannte „Farbfänger" enthält, welche aus der Waschflotte Farbstoffe entfernen sollen, gleichzeitig sollen aber Waschmittel an die Waschflotte abgegeben werden. Die Gewinnung einer entgifteten Abwasserflotte ist diesem Dokument aber nicht zu entnehmen. Auch in der WO 2008/138574 AI werden Behältnisse WO 2009/006395 describes a container which contains so-called "color catchers" which are intended to remove dyestuffs from the wash liquor, but at the same time detergents are to be delivered to the wash liquor in WO 2008/138574 AI containers are

beschrieben, welche auch Substanzen enthalten, die an das Waschwasser abgegeben werden. Eine Reinigung des Waschwasserabwasser ist diesem Dokument jedoch nicht zu entnehmen. described, which also contain substances that are released to the wash water. However, a cleaning of the wash water waste water is not apparent from this document.

Auch die WO 2009/07196 AI, die EP 1 889 000 AI, die WO 2009/004 295 AI sowie die US 2009/0163 399 AI beschreiben allesamt Mittel, welche WO 2009/07196 A1, EP 1 889 000 A1, WO 2009/004 295 A1 and US 2009/0163 399 A1 all describe agents which

Waschmittel an die Waschflotte abgeben. Dispense detergent to the wash liquor.

Besonders vorteilhaft bei dem Verfahren gemäß der Erfindung hingegen ist, dass die textilen Produkte auf Grund der Tatsache, dass die Waschflotte frei wird von Giftstoffen und sonstigen störenden Stoffen wie Schadstoffen etc. , nach dem Waschvorgang mit dem erfindungsgemäßen Behältnis keine oder zumindest keine bedenklichen Mengen von Resten der schädlichen Substanzen auf den gewaschenen textilen Produkten verbleiben, die sich sonst noch im Abwasser befinden könnten und beim Abpumpen der Waschflotte erneut auf die textilen Produkten absetzen könnten. Dadurch werden z.B. Allergien, die bisweilen beim Tragen von nach Verfahren gemäß dem Stand der Technik behandelten textilen Produkten zu verzeichnen waren, vermieden. Aber auch ein erheblicher Beitrag zur Vermeidung von Umweltbelastungen wird durch dieses erfindungsgemäße Verfahren geleistet, dadurch, dass die Waschflotte von Schadstoffen befreit wurde, bevor sie in die kommunalen Abwasserkläranlagen gelangen, wo insbesondere die wasserlöslichen Schadstoffe schlecht bis gar nicht entfernt werden können, und letztlich so ungehindert in das Trinkwasser gelangen können. Die Erfindung wird an Hand folgenden Beispiels näher erläutert. On the other hand, it is particularly advantageous in the process according to the invention that the textile products have no or at least no questionable amounts of water after the washing process with the container according to the invention due to the fact that the wash liquor is free of toxins and other interfering substances such as pollutants Remains of the harmful substances remain on the washed textile products, which could otherwise be in the wastewater and again settle on the textile products when pumping the wash liquor. As a result, for example, allergies, which were sometimes recorded when wearing treated according to the prior art textile products, avoided. But also makes a significant contribution to the prevention of environmental pollution by this method according to the invention, characterized in that the wash liquor was freed of contaminants before they reach the municipal wastewater treatment plants, where in particular the water-soluble pollutants can not be badly removed, and ultimately so can get into the drinking water unhindered. The invention will be explained in more detail with reference to the following example.

Ein aus naßfestem und gut wasserdurchlässigem Papiervlies hergestellter Beutel mit den Abmessungen 15cm x 15cm wird mit 60g eines rieselfähigen Mischgranulats befüllt und verschlossen. Das Befüllen und Verschließen erfolgt maschinell nach den in der Verpackungsindustrie häufig zum Einsatz kommenden Verfahren der 3- bzw. 4 Randversiegelung mittels Heizbacken oder Ultraschallköpfen. Hierzu wurde das Papiervlies mit einem Anteil von 30% geeigneter Schmelzfasern, sogenannte BICO-Fasern, ausgestattet. Das Granulat wurde zuvor mit Wasser gewaschen, getrocknet und anschließend in einem Labormischgerät homogenisiert und durch Siebung von Feinstteilchen getrennt. Das Granulat hat die Zusammensetzung 35% Aktivkohle, 20% A bag of 15cm x 15cm made from wet-strength and well-water-permeable paper web is filled with 60g of free-flowing mixed granules and sealed. The filling and closing is done by machine according to the in the packaging industry often used next method of 3 or 4 edge sealing by means of heating jaws or ultrasonic heads. For this purpose, the paper web was provided with a proportion of 30% of suitable melt fibers, so-called BICO fibers. The granules were previously washed with water, dried and then homogenized in a laboratory blender and separated by screening of Feinstteilchen. The granules have the composition 35% activated carbon, 20%

Klinoptilolith, 5% Bentonit Toxisorb, 5% Lewatit MonoPlus S108, 15% Soda, 5% PP-Accurel Pulver MP1000 , 15% Harnstoff. Clinoptilolite, 5% Bentonite Toxisorb, 5% Lewatit MonoPlus S108, 15% Soda, 5% PP Accurel Powder MP1000, 15% Urea.

Es war besonders überraschend, dass es mit der Erfindung möglich ist It was particularly surprising that it is possible with the invention

entgiftete oder schadstofffreie textile Produkte oder zumindest weitgehend entgiftete textile Produkte zu erhalten. to obtain detoxified or pollutant-free textile products or at least largely detoxified textile products.
