Description
Die Erfindung betrifft ein Imprägniermittel für textile Fasern, das zumindest einen Imprägnierstoff aus der Fluorcarbonharze und Fluorsilikone enthaltenden Gruppe aufweist. Weiters betrifft die Erfindung ein Verfahren zur Imprägnierung textiler Fasern.The The invention relates to an impregnating agent for textile Fibers that have at least one impregnating agent from the group containing fluorocarbon resins and fluorosilicones. The invention further relates to a method for impregnation textile fibers.
Zur Imprägnierung von textilen Fasern ist es bekannt, Derivate der Perfluorcarbonsäuren sowie der Perfluoralkansulfonsäuren heranzuziehen.to impregnation of textile fibers, it is known, derivatives of perfluorocarboxylic acids as well of perfluoroalkanesulfonic acids consulted.

Nachteilig bei den bekannten Verfahren ist, dass einerseits organische Lösungsmittel oder Lösungsmittelgemische verwendet werden, um das Imprägniermittel auf die Faser aufziehen zu können, andererseits häufig hohe Temperaturen bzw. aufwendige Verfahrensschritte dazu notwendig sind. Daher werden Imprägnierungen von beispielsweise Kleidungsstücken zum größten Teil in Putzereien und chemischen Reinigungen vorgenommen.adversely In the known methods, on the one hand, organic solvents or solvent mixtures used to the waterproofing agent to be able to pull on the fiber on the other hand, often High temperatures or complex process steps are necessary for this are. Therefore, impregnations of items of clothing, for example mostly in blowrooms and dry cleaners.
Ziel der Erfindung ist es, ein Imprägniermittel sowie ein Imprägnierverfahren zu schaffen, welches es erlaubt, die Imprägnierung von textilen Fasern mit geringem Aufwand und kostengünstig durchzuführen.aim The invention is an impregnating agent as well as an impregnation process to create, which allows the impregnation of textile fibers with little effort and inexpensive perform.
Diese Aufgabe wird mit einem Imprägniermittel der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, dass zumindest eine Substanz aus der Gruppe der kationischen Tenside enthalten ist. Die Aufgabe der kationischen Tenside ist die Reduktion der elektrostatischen Aufladung der Fasern. Baumwolle zum Beispiel weist eine negative Oberflächenladung auf, die durch das kationische Tensid neutralisiert wird. Dadurch wird die Haftung der imprägnierenden Substanz, wie beispielsweise ein Fluorcarbonharz, auf der Faser deutlich verbessert.This Task is done with an impregnating agent the one mentioned at the beginning Art solved according to the invention in that at least one substance from the group of cationic surfactants is included. The task of the cationic surfactants is the reduction the electrostatic charging of the fibers. Cotton, for example a negative surface charge which is neutralized by the cationic surfactant. Thereby becomes the liability of the impregnating Substance such as a fluorocarbon resin on the fiber clearly improved.
In einer bevorzugten Ausführung des Imprägniermittels ist das kationische Tensid aus der Gruppe der quartären Ammoniumverbindungen gewählt. Diese Verbindungen stellen den größten Anteil an kationischen Tensiden dar und sind daher leicht und kostengünstig erhältlich. Ein sehr häufig in Weichspülern verwendete quartäre Ammoniumverbindung ist Dimethyldioctadecylammoniumchlorid (DODMAC), das auch bei der vorliegenden Erfindung bevorzugt eingesetzt wird.In a preferred embodiment of the impregnating agent is the cationic surfactant from the group of quaternary ammonium compounds selected. These compounds represent the largest proportion of cationic surfactants and are therefore easily and inexpensively available. A very common in softeners quaternaries used Ammonium compound is dimethyldioctadecylammonium chloride (DODMAC), which is also preferably used in the present invention.
In einer alternativen Ausführung ist das kationische Tensid aus der Gruppe der quaternierten Alkanolamin-Fettsäureester gewählt.In an alternative version is the cationic surfactant from the group of quaternized alkanolamine fatty acid esters selected.
Untersuchungen haben gezeigt, dass, wenn das Imprägniermittel eine zusätzliche Komponente aus der Gruppe der oxidierend wirkenden Verbindungen enthält, die für eine ausreichende Imprägnierung der textilen Fasern notwendige Menge an Imprägnierstoff verringert werden kann. Da der Imprägnierstoff teuer ist, können durch Verwendung der oxidierend wirkenden Verbindungen, wie beispielsweise Peroxycarbonate oder Perborate, Kosten gesenkt werden. Zudem sind die zum Einsatz kommenden Imprägnierstoffe in Hinblick auf Umweltverträglichkeit nicht unproblematisch, daher ist eine Mengenreduktion an Imprägnierstoff jedenfalls wünschenswert.investigations have shown that if the impregnating agent has an additional Component from the group of oxidizing compounds contains the for adequate impregnation the amount of impregnating material necessary for the textile fibers can be reduced can. Because the impregnation is expensive, can by using the oxidizing compounds, such as Peroxycarbonate or perborate, costs can be reduced. Also are the impregnation materials used in terms of environmental sustainability not without problems, therefore a reduction in the amount of impregnation material at least desirable.
Um die Imprägniereigenschaften des Imprägniermittels zu erhöhen, enthält es eine zusätzliche Komponente aus der Gruppe der organofunktionellen Silane. Der selbe Effekt wird erzielt, wenn das Imprägniermittel eine zusätzliche Komponente aus der Gruppe der Siloxane aufweist.Around the impregnation properties of the impregnating agent to increase contains it an additional Component from the group of organofunctional silanes. The same Effect is achieved if the impregnating agent has an additional Has component from the group of siloxanes.
Die vorliegende Erfindung kann zur Imprägnierung unterschiedlichster textiler Fasern herangezogen werden. Je nach Beschaffenheit der Faser ist es notwendig, zu dem kationi schen Tensid weitere Tenside hinzuzufügen. Dies können anionische, nichtionische und ampholytische Tenside sowie Mischungen davon sein.The The present invention can be used for impregnation in a wide variety of ways textile fibers are used. Depending on the nature of the Fiber, it is necessary to add further surfactants to the cationic surfactant add. You can anionic, nonionic and ampholytic surfactants and mixtures be of it.
Eine weitere Verbesserung der Imprägniereigenschaften wird erzielt, wenn eine weitere Komponente aus der Gruppe der anorganischen wasserlöslichen Fluorverbindungen, wie beispielsweise KF, BF3, NH4F oder Mischungen davon, dem Imprägniermittel beigemengt werden.A further improvement in the impregnation properties is achieved if a further component from the group of the inorganic water-soluble fluorine compounds, such as KF, BF 3 , NH 4 F or mixtures thereof, is added to the impregnation agent.
Durch Zusatz einer weiteren Komponente aus der Gruppe der wässrigen Silikonemulsionen oder von Bienenwachs können die hydrophoben und oleophoben Eigenschaften des Imprägniermittels nochmals verstärkt werden.By Addition of a further component from the group of the aqueous Silicone emulsions or beeswax can make the hydrophobic and oleophobic Properties of the impregnating agent strengthened again become.
Eine einfache Dosierbarkeit ist gegeben, wenn das Imprägniermittel in einer wässrigen Dispersion oder in einer wässrigen Lösung vorliegt.A Easy dosing is given when the impregnating agent in an aqueous Dispersion or in an aqueous solution is present.
Das Verfahren zur Imprägnierung von textilen Fasern zeichnet sich dadurch aus, dass die textilen Fasern nach einem vorangegangenen Waschen in einer Waschmaschine mit einem Imprägnierungsmittel der erfindungsgemäßen Art behandelt werden, wobei die Imprägnierung sich unterbrechungsfrei anschließt.The Impregnation process of textile fibers is characterized in that the textile Fibers after a previous washing in a washing machine with an impregnating agent of the type according to the invention are treated, the impregnation joins without interruption.
Der Vorteil dieses Verfahrens liegt darin, dass es kostengünstig und ohne weiteren Aufwand in einer Waschmaschine durchgeführt werden kann. Imprägnierung, die zuhause durchgeführt werden können, werden für gewöhnlich mittels Spraydose oder einem Schwamm aufgetragen. Dies erschwert den gewünschten gleichmäßiger Auftrag der Imprägnierung. In der Waschmaschine wird das erfindungsgemäße Imprägniermittel mit Wasser in die Waschtrommel eingespült, verdünnt und durch die Bewegungen der Trommel gleichmäßig auf den textilen Fasern aufgezogen.The The advantage of this method is that it is inexpensive and can be carried out in a washing machine without further effort can. Impregnation, who performed at home can be be for usually applied with a spray can or a sponge. This complicates the desired even order impregnation. The impregnating agent according to the invention is washed with water in the washing machine Washing drum washed in, dilute and through the movements of the drum evenly on the textile fibers reared.
Die Imprägnierung kann an allen bekannten Fasern durchgeführt werden. Besonders vorteilhaft ist, dass es an natürlichen Fasern, insbesondere Baumwolle, Seide, Hanf, Leinen und Wolle und Kombinationen daraus angewendet wird. Ebenso ist die Imprägnierung von textilen Fasern synthetischen Ursprungs sowie Mischgewebe durchführbar.The impregnation can be carried out on all known fibers. Particularly advantageous is that it's natural Fibers, especially cotton, silk, hemp, linen and wool and Combinations of these are applied. The impregnation is also of textile fibers of synthetic origin as well as mixed fabrics feasible.
Besonders vorteilhaft ist es, dass die Imprägnierung der textilen Fasern bei einer Arbeitstemperatur unter 100°C erfolgt. Dadurch werden empfindliche Gewebe geschont; zahlreiche Fasern, vor allem synthetische, vertragen lediglich Temperaturen unter 40°C. Daher ermöglicht dieses Verfahren durch die reduzierte Temperatur eine Energieersparnis und somit wiederum eine weitere Kostenersparnis.Especially It is advantageous that the impregnation of the textile fibers at a working temperature below 100 ° C. This makes them sensitive Protected tissue; tolerate numerous fibers, especially synthetic only temperatures below 40 ° C. Therefore enables This process saves energy due to the reduced temperature and thus further cost savings.
Bei einer bevorzugten Variante des Verfahrens ist die Imprägnierung der textilen Fasern mit Seifenlauge auswaschbar. Dabei werden Imprägnierreste in der Waschmaschine im Kurz- oder Normalwaschgang entfernt und das Gewebe kann in einem weiteren Waschgang wieder imprägniert werden.at A preferred variant of the process is impregnation the textile fibers can be washed out with soapy water. This will leave impregnation residues in the washing machine in short or Normal wash cycle removed and the fabric can be washed in another wash impregnated again become.
Anhand eines nicht einschränkenden Ausführungsbeispiels soll die Erfindung näher erläutert werden:Based one non-limiting embodiment the invention is intended to be closer explained become:
Bei dem zu imprägnierenden Gewebe handelt es sich beispielsweise um eine Jacke aus einem Mischgewebe mit 60% Baumwolle und 40% Polyamid. Laut Herstellerangaben kann das Material bei maximal 40°C in einer handelsüblichen Waschmaschine gewaschen werden.at the one to be impregnated Fabric is, for example, a jacket made from a mixed fabric with 60% cotton and 40% polyamide. According to the manufacturer, can the material at a maximum of 40 ° C a commercial one Washing machine.
Das Kleidungsstück wird im trockenen Zustand in die Waschmaschine gegeben. Das Wählprogramm wird auf Kurzwaschgang bei 40°C eingestellt. In die Waschmittelkammer für Normalwäsche wird ein handelübliches Waschmittel in der üblichen Dosierung eingefüllt, in die Kammer für den Weichspüler wird das Imprägniermittel gegeben. Danach wird das Waschprogramm gestartet.The clothing is placed in the washing machine when dry. The dialer will on a short wash at 40 ° C set. In the detergent dispenser for normal laundry is a commercial one Detergent in the usual Dosage filled, into the chamber for the fabric softener becomes the impregnating agent given. The washing program is then started.
Im vorliegenden Beispiel besteht das Imprägniermittel aus 20 g organofuntionelles Silan (z.B.: Protectosil® SC von Degussa) und 30 g handelsüblichem Weichspüler pro Kilogramm Gewebe. Zusätzlich werden 5–10 Gew% Natriumpercarbonat zugesetzt. Organofunktionelle Silane sind auch ohne Weichspüler bei diesem Verfahren einsetzbar, allerdings hat sich gezeigt, dass deren Wirksamkeit durch den Weichspüler verstärkt wird. Dadurch kann die Menge an teurem Silan reduziert werden.In the present example, the impregnating agent consists of 20 g organofunctional silane (eg: Protectosil ® SC from Degussa) and 30 g commercial fabric softener per kilogram of fabric. In addition, 5-10% by weight sodium percarbonate is added. Organofunctional silanes can also be used in this process without fabric softener, but it has been shown that their effectiveness is enhanced by the fabric softener. This can reduce the amount of expensive silane.
In einer anderen Ausführung enthält das Imprägniermittel 50 g Fluorcarbonharz (z.B.: Apralon® FC 1980 der Fa. Bussetti) sowie 30 g Weichspüler.In another embodiment, the impregnating agent contains 50 g of fluorocarbon resin (for example: Apralon ® FC 1980 from Bussetti) and 30 g of fabric softener.
Der in beiden Ausführungsbeispielen verwendete Weichspüler weist beispielsweise eine Zusammensetzung nach Tabelle 1 auf:The in both embodiments used fabric softener has, for example, a composition according to Table 1:
Nach Abschluss des Waschvorgangs wird das Kleidungsstück auf üblichem Weg an der Luft oder im Trockner getrocknet.To At the end of the washing process, the garment is air or in the usual way tumble dried.
Das derart behandelte Kleidungsstück weist ausgezeichnete wasser-, öl- und schmutzabweisende Eigenschaften auf. Wird beispielsweise Wein auf das Kleidungsstück geleert, so perlt dieses vollständig ab und dringt nicht in das Gewebe ein. Gleichzeitig wird der Tragekomfort durch die Imprägnierung nicht beeinträchtigt, das Trageempfinden ist das gleiche wie das beim Tragen eines Kleidungsstückes, das mit einem Weichspüler allein behandelt wurde.The garment treated in this way exhibits excellent water, oil and dirt-repellent properties. For example, wine on the garment emptied, it pearles completely and does not penetrate the tissue. At the same time, the comfort through the impregnation not affected the feeling of wearing is the same as that of wearing a piece of clothing that with a fabric softener was treated alone.
Die Zusammensetzung des Imprägniermittels entsprechend den vorangegangenen Beispielen kann variiert werden. So können anstatt von Fluorcarbonharzen oder Silansystemen auch Silikonemulsionen als Imprägnierstoff eingesetzt werden, ebenso sind Kombination untereinander und/oder mit Bienenwachs möglich. Zudem kann die Wirkung durch Zusatz von oxiedierenden Bleichmitteln, wie Perboraten und Percarbonaten verstärkt werden.The Composition of the impregnating agent can be varied according to the previous examples. So can instead of fluorocarbon resins or silane systems, silicone emulsions as impregnation are used, as are combinations with each other and / or possible with beeswax. moreover can the effect by adding oxidizing bleaches, such as Perborates and percarbonates are reinforced.
Die Anwendung des Imprägniermittels ist nicht auf Kleidungstextilien beschränkt. Ebenso ist der Einsatz bei Wohntextilien wie Vorhänge und dergleichen möglich. Das Imprägniermittel kann auch beispielsweise bei Teppichen oder bei Textilien in Kraftfahrzeugen angewendet werden. Dazu wird das Mittel anstatt in einer Waschmaschine beispielsweise in einem Nassreinigungsgerät für Teppiche benutzt.The Application of the impregnating agent is not limited to clothing textiles. The same is the case for home textiles such as curtains and the like possible. The impregnating agent can also be used, for example, for carpets or textiles in motor vehicles be applied. This is done instead of in a washing machine used for example in a wet cleaning device for carpets.
