Abstract

The removal of stains from fabrics is difficult because of the different chemical composition of staining substances, which extends from plant juices to coloured pastes, for example ballpoint paste. To date, stain removers suited to the particular staining substance have been employed both domestically and in commercial cleaning. Since the customary stain removers contain volatile, often flammable solvents, a possibility for long action times, which in conjunction with water brings about reliable washing out of the coloured pigments, has been achieved by treatment with stain removing components which do not contain volatile solvents.

Description

Die Erfindung betrifft ein Verfahren zum Entfernen von Flecken aus Textilien oder dgl., insbesondere zum Entfernen von Kugel- oder Flizschreiberflecken.The invention relates to a method for removing stains from textiles or the like, in particular for removing ball or pens.

Für das Entfernen von Flecken aus Textilien oder dgl. lassen sich grundsätzlich zwei Grundstoffe einsetzen, nämlich einmal die sogenannten waschaktiven Substanzen, die im Zusammenwirken mit Wasser die Ver­schmutzung von der Faseroberfläche lösen, so daß diese von der Wasch­flotte aufgenommen werden. Sogenannter Fettschmutz wird hierbei in der Waschflotte emulgiert und sogenannter Pigmentschmutz wird in der Waschflotte suspendiert. Bei wasserempfindlichen Geweben, kleinen Flecken auf Fettbasis oder auch auf Lackbasis werden anstelle von wasch­aktiven Substanzen Lösungsmittel eingesetzt, die ggf. auf die chemische Struktur des betreffenden Fleckes abgestimmt sein müssen. So wird bei­spielsweise 1.1.1-Trichloräthan als sogenanntes Fleckenwasser für die Einzelbehandlung, aber auch zum Detachieren von Textilien in der chemi­schen Reinigung eingesetzt. Daneben ist die Verwendung von sogenanntem Waschbenzin, Lacklösungsmittel, wie beispielsweise sogenannte Nitrover­ dünnung etc., bekannt. Die Verwendung derartiger Lösungsmittel, die alle leichtflüchtig und z. T. entflammbar sind, ist wegen der inzwischen bekannt gewordenen Gefahr von Gesundheitsschädigungen nur unter besonderen Vorsichtsmaßnahmen zulässig. Hinzu kommt noch, daß mit zunehmendem Einsatz von Kunstfasern unterschiedlichster chemischer Zusammensetzung allein oder auch in Mischungen untereinander oder in Mischungen mit Naturfasern bei der Verwendung von Lösungsmitteln Vorsicht geboten ist, da u. U. die Gefahr besteht, daß durch das betref­fende Lösungsmittel eine Faserkomponente in einem derartigen Mischgewebe angelöst und damit das Gewebe z. T. zerstört wird. Ebenso ist es möglich, daß durch ein derartiges Lösungsmittel die Farbpigmente bei gefärbten Fasern angegriffen werden können, so daß neben der Fleckbeseitigung auch eine Ent- oder Verfärbung der behandelten Stelle auftritt. Ein beson­derer Nachteil der Verwendung derartiger Lösungsmittel, die allesamt in hohem Maße flüchtig sind, besteht darin, daß bei der Fleckenbehandlung keine ausreichende Behandlungszeit möglich ist, so daß beispielsweise bei einem Farbfleck mit Bindemittel, wie beispielweise einem Lackfleck oder einem Kugelschreiberfleck, das Bindemittel zwar gelöst wird, jedoch die an der Faser anhaftenden Pigmentteilchen nicht vollständig von der Faser getrennt werden können, so daß eine Restverfärbung bleibt. Ein weiteres Problem ist hierbei eine randfreie Fleckentfernung, die nur bei vollständigem Eintauchen des betreffenden Textilstückes in das Lö­sungsmittel möglich wäre. Da im täglichen Leben eine Vielzahl von fleckenden Substanzen unterschiedlichster chemischer Zusammensetzung verwendet werden, die den Einsatz der unterschiedlichsten Lösungsmittel erfordern, ist man seit einiger Zeit dazu übergegangen, Spezial-Fleckentfernungsmittel herzustellen und anzubieten, die als geschlossenes Sortiment abgegeben und dann nach entsprechender Wahl im Haushalt eingesetzt werden können. Da diese Spezial-Fleckentfernungsmittel allesamt auf der Basis flüchtiger Lösungsmittel aufgebaut sind, war eine befriedigende, randfreie Fleckent­fernung nur bedingt möglich, wobei die Gefahr einer Gesundheitsgefährdung durch die verwendeten Lösungsmittel nicht in allen Fällen ausgeschlossen werden konnte.Basically, two basic substances can be used to remove stains from textiles or the like, namely the so-called wash-active substances which, in interaction with water, loosen the soiling from the fiber surface so that they are absorbed by the washing liquor. So-called grease dirt is emulsified in the wash liquor and so-called pigment dirt is suspended in the wash liquor. In the case of water-sensitive fabrics, small grease-based stains or lacquer-based stains, solvents are used instead of wash-active substances, which may have to be matched to the chemical structure of the stain in question. For example, 1.1.1-trichloroethane is used as so-called stain water for individual treatment, but also for detaching textiles in chemical cleaning. In addition, the use of so-called white spirit, paint solvents, such as so-called nitrover thinning etc., known. The use of such solvents, all of which are volatile and e.g. T. are flammable, is only permitted under special precautionary measures due to the now known risk of damage to health. In addition, with increasing use of synthetic fibers of different chemical compositions alone or in mixtures with one another or in mixtures with natural fibers, caution is advised when using solvents, since u. U. there is a risk that a fiber component in such a mixed fabric is dissolved by the solvent in question and thus the fabric z. T. is destroyed. It is also possible that the color pigments in colored fibers can be attacked by such a solvent, so that, in addition to the removal of stains, the treated area is also discolored or discolored. A particular disadvantage of using such solvents, all of which are highly volatile, is that sufficient treatment time is not possible in the treatment of stains, so that, for example, in the case of a color stain with a binder, such as a paint stain or a ballpoint pen stain, the binder is dissolved However, the pigment particles adhering to the fiber cannot be completely separated from the fiber, so that a residual discoloration remains. Another problem here is edge-free stain removal, which would only be possible if the textile piece in question was completely immersed in the solvent. Since a multitude of staining substances of different chemical compositions are used in daily life, which require the use of a wide variety of solvents, it has been started for some time to produce and offer special stain removers, which are supplied as a closed range and then according to choice in the household can be used. Since these special stain removers are all based on volatile solvents, satisfactory, rimless stain removal was only possible to a limited extent, and the risk of health damage from the solvents used could not be excluded in all cases.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren zum Fleckent­fernen zu schaffen, das aufgrund der gewählten Mittel lange Einwirkungs­zeiten und eine randfreie Fleckentfernung ermöglicht.The invention is based on the object of providing a method for removing stains which, due to the means chosen, enables long exposure times and edge-free stain removal.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die verschmutzte Stelle in wenigstens einer ersten Fleckentfernungskomponente, aufweisend eine Mischung von Glykolsäure-n-butylester, Diätylenglykolmono-n-butyl­äther und Fettamin-Derivat mit Betainstruktur und/oder einer zweiten Flecke ntfernungskomponente, aufweisend eine Mischung von Essigsäure-(diäthylenglykolmono-n-butyläther)ester, aufweist und einer Mischung von mindestens einem nichtionogenen Tensides und mit mindestens einem emulgierbaren Tensides, welches als Kation ein Amin enthält, getränkt und nach einer vorgebbaren Einwirkungszeit die getränkte Stelle zusätzlich mit einer geringen Wassermenge getränkt, gewalkt und anschließend mit Wasser ausgewaschen wird. Beide Fleckentfernerkomponenten sind nicht toxisch, praktisch nicht flüchtig und wasserlöslich. Es hat sich gezeigt, daß je nach Art der fleckenden Substanz die Behandlung der verfleckten Stelle mit nur einer Fleckentfernerkomponente ausreicht, daß jedoch für die Behandlung von bisher nicht zu entfernenden Flecken der Einsatz beider Komponenten notwendig ist. So reicht es beispielsweise aus, Flecken von Obstsäften nur mit der ersten Fleckentfernerkomponente zu tränken und nach einer Einwirkungszeit von etwa 10 bis 15 Minuten unter der Zugabe von einer geringen Wassermenge mechanisch zu reiben bzw. zu walken und anschliessend die getränkte Stelle mit Wasser auszuwaschen. Durch Anstrichmittel verursachte Flecke können in einer Vielzahl von Fällen durch die Behandlung mit der zweiten Fleckentfernungskomponente in der vorstehend beschriebenen Weise entfernt werden. Insbesondere Flecken, die von Kugelschreiber oder Filzschreiber oder die von sogenannten Markierstiften verursacht sind, müssen in der Weise behandelt werden, daß zunächst die verfleckte Stelle je nach Grad der Verschmutzung über mehrere Stunden getränkt wird, dann anschließend die zweite Fleckentfernerkomponente zur ersten Fleckentfernerkomponente hinzu gegeben wird, so daß beide Komponenten über eine weitere Einwir­kungszeit von beispielsweise 10 Minuten bis zu einer Stunde auf die Ver­schmutzung einwirken können. Anschließend wird unter Zugabe von etwas Wasser das Gewebe mechanisch bearbeitet, beispielsweise gewalkt oder gegeneinander gerieben und anschließend die aus den beiden Fleckentfernerkomponenten und Wasser bestehende Tränkung ausgespült. Ein weiterer Vorteil besteht darin, daß die erfindungsgemäßen Mittel nicht kennzeichnungspflichtig im Hinblick auf die Entflammbarkeit sind, da der Flammpunkt der ersten Komponente 75° C und der zweiten Komponente 108° C beträgt. Ferner ist von Vorteil, daß hinsichtlich der Raumluftbelastung die Lösungsmittelanteile beider Komponenten in den MAK-Werten cm³/m³ (ppm) und mg/m³ Luft in Kennwert-Tabellen nicht aufgeführt sind und somit die Anwendung in geschlossenen Räumen möglich ist.This object is achieved in that the soiled area in at least a first stain removal component, comprising a mixture of glycolic acid n-butyl ester, dietylene glycol mono-n-butyl ether and fatty amine derivative with betaine structure and / or a second stain removal component, comprising a mixture of Acetic acid (diethylene glycol mono-n-butyl ether) ester, and a mixture of at least one nonionic surfactant and at least one emulsifiable surfactant, which contains an amine as cation, soaked and after a predeterminable exposure time the soaked area is additionally soaked with a small amount of water, drummed and then washed out with water. Both stain remover components are non-toxic, practically non-volatile and water-soluble. It has been shown that, depending on the type of staining substance, treatment of the stained area with only one stain remover component is sufficient, but that the use of both components is necessary for the treatment of stains which have not hitherto been removed. For example, it is sufficient to soak stains from fruit juices only with the first stain remover component and, after an exposure time of around 10 to 15 minutes, mechanically rub or walk with the addition of a small amount of water and then wash the soaked area with water. Paint stains can be removed in a variety of cases by treatment with the second stain removing component as described above. In particular, stains caused by ballpoint pens or felt-tip pens or by so-called marking pens must be treated by first soaking the stained area for several hours depending on the degree of soiling, then adding the second stain remover component to the first stain remover component , so that both components can act on the contamination over a further exposure time of, for example, 10 minutes to one hour. The fabric is then mechanically processed with the addition of a little water, for example tumbled or rubbed against one another, and the impregnation consisting of the two stain-removing components and water is then rinsed out. Another advantage is that the agents according to the invention do not have to be labeled with regard to flammability, since the flash point of the first component is 75 ° C. and the second Component is 108 ° C. It is also an advantage that the solvent content of both components in the MAK values cm³ / m³ (ppm) and mg / m³ air are not listed in the characteristic value tables with regard to indoor air pollution and therefore use in closed rooms is possible.

Erfindungsgemäß besteht die erste Fleckentfernungskomponente zur Durchführung des Verfahrens aus einer Mischung von
10 - 80%, vorzugsweise 39 - 40% Glykolsäure-n-butylester
19 - 80%, vorzugsweise 39 - 40% Diäthylenglykolmono-n-butyläther
1 - 40%, vorzugsweise 19 - 20% Fettamin-Derivat mit Betainstruktur.According to the invention, the first stain removal component for carrying out the method consists of a mixture of
10-80%, preferably 39-40% glycolic acid n-butyl ester
19-80%, preferably 39-40%, diethylene glycol mono-n-butyl ether
1 - 40%, preferably 19 - 20% fatty amine derivative with betaine structure.

Erfindungsgemäß besteht die zweite Fleckentfernerkomponente zur Durchführung des Verfahrens aus einer Mischung von Kokosfettsäure­monoethanolamid mit 4,5 - 6 Mol Ethylenoxid Addukte, 97-98%iger Dodecylbenzolsulfonsäure, reines Triäthanolamin, Essigsäure­(diäthylenglykolmono-n-butyläther) ester.According to the invention, the second stain remover component for carrying out the process consists of a mixture of coconut fatty acid monoethanolamide with 4.5-6 moles of ethylene oxide adducts, 97-98% dodecylbenzenesulfonic acid, pure triethanolamine, acetic acid (diethylene glycol mono-n-butyl ether) ester.

In einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß als emulgierbare anionaktive Tenside eine Mischung eingesetzt wird aus
1 - 25%, vorzugsweise 16% Kokosfettsäuremonoethanolamid mit 4,5 - 6 Mol Ethylenoxid Addukte
1 - 40%, vorzugsweise 20% Dodecylbenzolsulfonsäure, 97-98%ig
1 - 20%, vorzugsweise 9,2% reine Triäthanolamin.
1 - 12%, vorzugsweise 9,8% Wasser
96 - 3%, vorzugsweise 45,0% Essigsäure- (diäthylenglykolmono-n-­butyläther)ester.In a preferred embodiment of the invention it is provided that a mixture of is used as the emulsifiable anionic surfactants
1-25%, preferably 16%, coconut fatty acid monoethanolamide with 4.5-6 moles of ethylene oxide adducts
1 - 40%, preferably 20% dodecylbenzenesulfonic acid, 97-98%
1 - 20%, preferably 9.2% pure triethanolamine.
1 - 12%, preferably 9.8% water
96-3%, preferably 45.0% acetic acid (diethylene glycol mono-n-butyl ether) ester.

Die beiden Bestandteile Dodecylbenzolsulfonsäure und Triäthanolamin werden als wasserhaltige Mischung eingesetzt, wobei der Wasseranteil vorzugsweise 9,8% beträgt.The two components dodecylbenzenesulfonic acid and triethanolamine are used as a water-containing mixture, the water content preferably being 9.8%.

Hierdurch ist gewährleistet, daß bei der Anwendung sich die in der Mi­schung enthaltenen Tenside nicht von dem als Lösungsmittel dienenden Essigsäure- (diäthylemglykolmono-n-butyläther)ester trennen und so die volle Einwirkung auf das zu reinigende Gewebe erhalten bleibt.This ensures that the surfactants contained in the mixture do not separate from the acetic acid (diethylemglycol mono-n-butyl ether) ester used as the solvent and the full effect on the tissue to be cleaned is retained.

Erfindungsgemäß kann dieses emulgierbare Tensid auch durch Triäthanolaminalkylsulfat gebildet werden,According to the invention, this emulsifiable surfactant can also be formed by triethanolamine alkyl sulfate,

Erfindungsgemäß können wahlweise die im Anspruch 6 angegebenen Amine eingesetzt werden.According to the invention, the amines specified in claim 6 can optionally be used.

Der anionische Teil der Tenside kann wahlweise einzeln oder in einer entsprechenden Mischung bestehen aus Fettalkylschwefelsäureester oder Fettsäuren. Sie können auch als Salze eingesetzt werden, wobei dann diese Verbindungen auch als wasserhaltige Verbindungen zum Einsatz kommen können.The anionic part of the surfactants can optionally consist individually or in a corresponding mixture of fatty alkyl sulfuric acid ester or fatty acids. They can also be used as salts, in which case these compounds can also be used as water-containing compounds.

Ferner können die anionischen Tenside in Form ihrer freien Säure, wie beispielsweise Fettsäuren, insbesondere Dodecylbenzolsulfonsäure in situ mit den im Anspruch 6 angegebenen Aminen hergestellt und eingesetzt werden.Furthermore, the anionic surfactants in the form of their free acid, such as, for example, fatty acids, in particular dodecylbenzenesulfonic acid, can be prepared and used in situ with the amines specified in claim 6.

Die vorstehend angegebenen Anteile der einzelnen Mischungsbestandteile für die beiden Fleckentfernerkomponenten sind als Gewichts-Prozente definiert.The proportions of the individual mixture constituents given above for the two stain remover components are defined as percentages by weight.

Der Vorteil der beiden Fleckentfernerkomponenten besteht darin, daß zum Fleckentfernen nur die verschmutzte Stelle in einer flachen Schale getränkt zu werden braucht, wobei eine längere Einwirkungszeit von mehreren Stunden möglich ist, da beide Fleckentfernerkomponenten praktisch nicht flüchtig sind. Die Auswahl, ob jeweils die erste oder die zweite Fleckentfernerkomponente allein oder im Zusammenwirken miteinander eingesetzt werden, richtet sich im wesentlichen nach der den Fleck verur­sachenden Substanz. Bei der Verwendung beider Fleckentfernerkomponenten nacheinander richtet sich auch die Reihenfolge der Anwendung im wesent­lichen nach der den Fleck verursachenden Substanz. In der Regel erfolgt jedoch die Tränkung zunächst mit der ersten Fleckentfernerkpomponente, dann wird die zweite Fleckentfernerkomponente zugegeben und nach einer kurzen Einwirkungszeit etwas Wasser zugegeben und nach einer weiteren Einwirkungszeit unter mechanischem Walken oder Reiben der verschmutzten Stelle die Tränkung mit Wasser insgesamt ausgeschwemmt.The advantage of the two stain remover components is that only the soiled area in a flat dish needs to be soaked for stain removal, a longer exposure time of several hours being possible, since both stain remover components are practically non-volatile. The choice of whether the first or the second stain remover component is used alone or in cooperation with one another essentially depends on the substance causing the stain. When using both stain remover components one after the other, the order of application also depends essentially on the substance causing the stain. As a rule, however, the impregnation is first carried out with the first stain remover component, then the second stain remover component is added and, after a short exposure time, a little water is added, and after a further exposure time, the impregnation with water is completely washed out with mechanical flexing or rubbing the soiled area.

Anstelle einer Tränkung in Badform, wie dies insbesondere für die Anwen­dung im Haushalt erfolgt, ist es für den gewerblichen Bereich möglich, die verschmutzte Stelle jeweils mit den Fleckentfernerkomponenten zu bedampfen, bzw. in der im gewerblichen Bereich üblichen Detachiertechnik zu behandeln.Instead of an impregnation in the form of a bath, as is particularly the case for use in the household, it is possible for the commercial sector to vaporize the stain-removing components in each case, or to treat it in the detection technique customary in the commercial sector.
