Dies gilt insbesondere für lipophile Produkte, wie zum Beispiel Schmieröle, Motoröle, Fette, Wachse und dergleichen, aber zum Beispiel auch für Pigmente. Zur Verminderung der Verschmutzung von Textilien werden im Stand der Technik so genannte„Soil-Release“ Additive vorgeschlagen, die Waschmitteln zugesetzt werden, und während eines Waschvorganges auf die Oberfläche von Textilien aufziehen. The daily use of textiles, for example by wearing textile clothing, inevitably causes the textiles to become soiled. Many stains or soils, which are summarized below under the term "stains" are very difficult or with considerable effort without leaving residues from the textiles removable. This is especially true for lipophilic products, such as lubricating oils, motor oils, fats, waxes and the like, but also for example for pigments. In order to reduce the contamination of textiles so-called "soil release" additives are proposed in the art, the detergents are added, and raise during a washing process on the surface of textiles.
DE 101 525 308 A1 beschreibt zu diesem Zweck die Verwendung von Polymerisaten aus Polyisocyanaten und polymeren Polyolen. Des Weiteren beschreibt DE 10 2007 013217 A1 anionische Soil-Release-Polyester, die aus Terephthalsäure, Sulfoisophthalsäure-(Poly)alkylenglykol und einer nichtionischen Endgruppe bestehen. DE 101 525 308 A1 describes for this purpose the use of polymers of polyisocyanates and polymeric polyols. Furthermore, DE 10 2007 013217 A1 describes anionic soil release polyesters which consist of terephthalic acid, sulfoisophthalic acid (poly) alkylene glycol and a nonionic end group.
Die im Stand der Technik bekannten Soil-Release Wirkstoffe zeigen jedoch entweder eine hohe Selektivität für eine bestimmte Anschmutzung, was bedeutet, dass nur eine bestimmte Art von Schmutz, beispielsweise lediglich ölbasierte Anschmutzungen, oder nur Pigmente oder andere hydrophilere Anschmutzungen entfernt werden, oder entfalten ihr Wirkungsspektrum lediglich auf einer bestimmten Sorte von Gewebe, beispielsweise lediglich auf Polyamiden oder auf auf Baumwolle basierenden Geweben. However, the soil-release agents known in the art either exhibit high selectivity for a particular soiling, meaning that only one particular type of soil, for example, only oil-based soils, or only pigments or other more hydrophilic soils, are removed or unfolded Range of action only on a certain type of tissue, for example, only on polyamides or on cotton-based tissues.
Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine Verwendung eines Copolymers anzugeben, das aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel besteht, sowie ein Textilpflegeprodukt bereitzustellen, das Wiederanschmutzungen von Textilien vorbeugt und/oder vermindert oder die Entfernbarkeit von Anschmutzungen aus den Textilien verbessert. Ferner ist es eine Aufgabe der vorliegenden Erfindung ein Verfahren zur Ausrüstung von Textilien mit einer Soil-Release Schutzschicht anzugeben, durch das Textilien vor Wiederanschmutzungen geschützt werden und/oder auf das Textil aufziehende Anschmutzungen leichter entfernt werden können. Starting from this prior art, it is an object of the present invention to provide a use of a copolymer consisting of N-Isopropylacrylamideinheiten, methacrylic acid units and optionally at least one crosslinking agent, and to provide a fabric care product that prevents and / or reduces Wiederanschmuckenungen of textiles Improved removability of soiling from textiles. Furthermore, it is one Object of the present invention to provide a method for finishing textiles with a soil-release protective layer, are protected by the textiles from re-soiling and / or staining on the fabric soiling can be easily removed.
Überraschenderweise wurde gefunden, dass diese Aufgabe durch die Verwendung eines Copolymers, das aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel besteht (kurz: NIPAM-co-MAc), gelöst wird. Die in dem Copolymer enthaltenen N- Isopropylacrylamideinheiten und Methacrylsäureeinheiten werden durch nachfolgende Formeln dargestellt: Surprisingly, it has been found that this object is achieved by the use of a copolymer consisting of N-Isopropylacrylamideinheiten, methacrylic acid units and optionally at least one crosslinking agent (in short: NIPAM-co-MAc). The N-isopropylacrylamide units and methacrylic acid units contained in the copolymer are represented by the following formulas:
N-Isopropylacrylamid (NIPAM): N-Isopropylacrylamide (NIPAM):
Ohne an die Theorie gebunden zu sein wird angenommen, dass die in dem Copolymer enthaltenen N- Isopropylacrylamideinheiten aufgrund ihrer chemischen Konstitution sehr gut auf unterschiedliche Gewebearten, wie zum Beispiel Cellulose-basierte Gewebe (Baumwolle), Polyamidgewebe, Polyestergewebe, Mischgewebe und dergleichen aufziehen und dort eine Art Schutzschicht oder Schutzfilm bilden, der einen ungehinderten Zugang von Anschmutzungen zu dem oder in das Gewebe verhindert und damit einer Anschmutzung oder Wiederanschmutzung vorbeugt oder eine solche effektiv verringert oder gar verhindert. Ferner wird angenommen, dass die Methacrylsäureeinheiten in dem Copolymer aufgrund des hohen hydrophilen Anteils ein Entfernen der Anschmutzungen vom oder aus dem Gewebe erleichtern. Durch die Methacrylsäureeinheiten wird zudem die Filmbildung auf dem Gewebe unterstützt, so dass eine so genannte Soil-Release Schutzschicht gleichförmig auf der Oberfläche des Gewebes ausgebildet werden kann. Hierbei wird eine flächendeckende „Schutzabdeckung“ des textilen Gewebes durch die sterisch anspruchsvollen Ketten aus N- Isopropylacrylamideinheiten und Methacrylsäureeinheiten gefördert, so dass ein ungehinderter Zugang von Anschmutzungen zu oder in das Gewebe verhindert oder zumindest deutlich reduziert wird. Die Methylgruppen in den Methacrylsäureeinheiten sorgen zudem für einen gewissen hydrophoben Anteil des Copolymers und damit auch dafür, dass hydrophobe Anschmutzungen, wie Öle, Fette und dergleichen, gar nicht erst in das Gewebe eindringen, sondern an dessen Oberfläche abgefangen werden, so dass ein Auswaschen der Anschmutzungen sehr einfach möglich ist. Without being bound by theory, it is believed that due to their chemical constitution, the N-isopropylacrylamide units contained in the copolymer are very well suited to and applied to different types of fabrics, such as cellulose-based fabrics (cotton), polyamide fabrics, polyester fabrics, blended fabrics, and the like forming a kind of protective layer or protective film which prevents unimpeded access of soiling to or into the tissue and thus prevents or effectively reduces or even prevents soiling or re-soiling. Further, it is believed that the methacrylic acid units in the copolymer facilitate removal of stains from or from the fabric due to the high hydrophilic content. The methacrylic acid units also promote film formation on the fabric, so that a so-called soil-release protective layer can be uniformly formed on the surface of the fabric. Here, a comprehensive "protective cover" of the textile fabric is promoted by the sterically demanding chains of N-Isopropylacrylamideinheiten and methacrylic acid units, so that unimpeded access of soiling to or into the tissue is prevented or at least significantly reduced. The methyl groups in the methacrylic acid units also provide for a certain hydrophobic portion of the copolymer and thus also for hydrophobic soiling, such as oils, fats and Like, not at first penetrate into the tissue, but are intercepted on the surface, so that a washing out of soiling is very easy.
In Summe zeichnet sich das erfindungsgemäß verwendete Copolymer durch hohe hydrophile aber auch lipophile Anteile aus, so dass ferner Anschmutzungen unterschiedlicher Art, also lipophile Anschmutzungen, wie zum Beispiel Fette, Wachse oder Öle, und auch hydrophile Anschmutzungen wie zum Beispiel Pigmente, Farbstoffe und dergleichen, vermindert oder sogar verhindert oder sehr leicht wieder entfernt werden können. In sum, the copolymer used according to the invention is distinguished by high hydrophilic but also lipophilic fractions, so that further soiling of different types, ie lipophilic soiling, such as, for example, fats, waxes or oils, and also hydrophilic soiling, such as, for example, pigments and the like, diminished or even prevented or removed very easily.
Das erfindungsgemäß verwendete Copolymer liegt hierbei vorzugsweise in Form eines Hydrogels vor. Unter dem Begriff „Hydrogel“ wird im Sinne der Erfindung ein Wasser enthaltendes, aber wasserunlösliches Copolymer verstanden, dessen Moleküle chemisch, zum Beispiel durch kovalente oder ionische Bindungen, oder physikalisch, zum Beispiel durch Schlaufenbildung der Polymerketten, zu einem dreidimensionalen Netzwerk verknüpft sind. Das Hydrogel besitzt hierbei die Eigenschaft aufgrund der hohen hydrophilen Anteile im Copolymer in Wasser unter beträchtlicher Volumenzunahme zu quellen, ohne den stofflichen Zusammenhalt zu verlieren. Hierdurch kann eine Ablösung und Entfernung von Anschmutzungen erleichtert und damit verbessert werden. The copolymer used according to the invention is preferably present in the form of a hydrogel. For the purposes of the invention, the term "hydrogel" is understood as meaning a water-containing, but water-insoluble copolymer whose molecules are linked chemically, for example by covalent or ionic bonds, or physically, for example by looping of the polymer chains, to form a three-dimensional network. The hydrogel has the property because of the high hydrophilic proportions in the copolymer in water to swell under considerable volume increase without losing the material cohesion. In this way, a detachment and removal of stains can be facilitated and thus improved.
Als Vernetzungsmittel kann jegliches die N-Isopropylacrylamideinheiten und/oder Methacrylsäureeinheiten vernetzende Mittel eingesetzt werden. Vorzugsweise werden Vernetzungsmittel eingesetzt, die die Acrylamideinheiten und Methacrylsäureeinheiten vernetzen, wie insbesondere N,N'-Methylenbisacrylamid (MBA), das ein symmetrisches, nicht-konjugiertes bifunktionelles Vinyl-Monomer ist. As the crosslinking agent, any of the N-isopropylacrylamide units and / or methacrylic acid unit crosslinking agents can be used. Preference is given to using crosslinking agents which crosslink the acrylamide units and methacrylic acid units, in particular N, N'-methylenebisacrylamide (MBA), which is a symmetrical, unconjugated bifunctional vinyl monomer.
Im erfindungsgemäß verwendeten Copolymer liegt das Molverhältnis von aus N-Isopropylacrylamid zu aus dem Vernetzungsmittel erhaltenen Einheiten vorzugsweise im Bereich von 1000:1 bis 10: 1 , insbesondere von 200:1 bis 20: 1 und besonders bevorzugt von 50:1 bis 25: 1. In the copolymer used in the present invention, the molar ratio of N-isopropylacrylamide to units obtained from the crosslinking agent is preferably in the range of 1000: 1 to 10: 1, more preferably 200: 1 to 20: 1, and particularly preferably 50: 1 to 25: 1 ,
Des Weiteren erfindungsgemäß wird auch ein Textilpflegeprodukt offenbart, das mindestens ein Copolymer enthält, das aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel besteht. Dies schließt mit ein, dass das erfindungsgemäße Textilpflegeprodukt ein oder mehrere Copolymere enthält, die aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehen. Further, according to the present invention, there is also disclosed a fabric care product containing at least one copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent. This implies that the fabric care product of the invention contains one or more copolymers consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent.
Hierbei wird unter „Textilpflegeprodukt“ im Sinne der vorliegenden Erfindung jegliches Wasch-, Reinigungs- und Pflegemittel verstanden, das zur Reinigung und Pflege von Textilien, wie Heim- und Bekleidungstextilien, verwendet wird. Hierzu zählen insbesondere Vollwaschmittel, Spezialwaschmittel, wie zum Beispiel Feinwaschmittel, Wollwaschmittel und dergleichen, Waschhilfsmittel, Wäschepflegemittel, Wäschesprays, Bügelhilfsmittel, Wäschevorbehandlungsmittel und Wäschenachbehandlungsmittel. In the context of the present invention, "textile care product" means any washing, cleaning and care agent used for cleaning and care of textiles, such as home and clothing textiles. These include in particular heavy duty detergents, special detergents, such as, for example, mild detergents, wool detergents and the like, washing aids, Laundry care products, laundry sprays, ironing aids, laundry pre-treatment agents and laundry aftertreatment agents.
Zur Vermeidung von Redundanz, wird bezüglich der Definition des aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehenden Copolymers sowie der erfindungsgemäß erzielten Effekte ergänzend auf die vorstehenden Erläuterungen verwiesen. To avoid redundancy, reference is made to the above explanations for the definition of the consisting of N-Isopropylacrylamideinheiten, methacrylic acid units and optionally at least one crosslinking agent copolymer and the effects achieved according to the invention.
Es hat sich überraschend herausgestellt, dass durch das erfindungsgemäße Textilpflegeprodukt Anschmutzungen oder Wiederanschmutzungen von Textilien unterschiedlicher Art vorgebeugt werden kann oder diese effektiv verringert werden und zudem auch eine Entfernung von Anschmutzungen aus den Textilien erleichtert wird. Es wird davon ausgegangen, dass, um diese Effekte zu erzielen, das aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehende Copolymer auf das textile Gewebe aufzieht und eine Art Schutzschicht oder Schutzfilm ausbildet, die Anschmutzungen verhindert oder zumindest reduziert und deren Entfernen erleichtert. Die mit dem erfindungsgemäßen Textilpflegeprodukt behandelten Textilien bleiben somit länger sauber und können auch nach mehreren Wäschen ohne Spuren von vormals vorhandenen Anschmutzungen erhalten werden. Hierbei hat sich gezeigt, dass sich die Schutzschicht auf unterschiedlichen Gewebesorten ausbilden lässt, wie zum Beispiel Polyester-basiertem Gewebe, Cellulose-basiertem Gewebe, Polyamid-basiertem Gewebe und jeglicher Art von Mischgewebe. Auch wurde gefunden, dass durch Anwendung des erfindungsgemäßen Textilpflegeprodukts unterschiedliche Arten von Anschmutzungen, also sowohl lipophile Anschmutzungen als auch hydrophile Anschmutzungen verringert oder sogar verhindert oder effektiv entfernt werden können. It has surprisingly been found that can be prevented by the fabric care product according to the invention stains or Wiederanschmutzungen of textiles of different types or these are effectively reduced and also a removal of soiling from the textiles is facilitated. It is believed that in order to achieve these effects, the copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent wears on the textile fabric and forms a kind of protective layer or protective film which prevents or at least reduces stains and facilitates their removal , The textiles treated with the fabric care product according to the invention thus remain clean longer and can be obtained even after several washes without traces of previously existing soils. It has been found that the protective layer can be formed on different types of fabric, such as polyester-based fabric, cellulose-based fabric, polyamide-based fabric and any type of blended fabric. It has also been found that by using the textile care product according to the invention different types of soiling, ie both lipophilic soiling and hydrophilic soiling can be reduced or even prevented or effectively removed.
Eine vorteilhafte Weiterbildung des erfindungsgemäßen Textilpflegeprodukts zeichnet sich dadurch aus, dass die Gesamtmasse an aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehendem Copolymer, bezogen auf die Gesamtmasse des Textilpflegeprodukts, 0,001 Masse% bis 10 Masse%, insbesondere 0,01 Masse% bis 5 Masse% und insbesondere 1 Masse% beträgt. Werden mehrere aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehende Copolymere in Kombination eingesetzt, so bezieht sich die Gesamtmasse auf die Gesamtmasse aller im Textilpflegeprodukt enthaltenen, aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehenden, Copolymere. Mit anderen Worten bedeutet dies, dass sofern beispielsweise zwei aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehende Copolymere in Kombination eingesetzt werden, ihre Gesamtmasse 0,001 Masse% bis 10 Masse% beträgt. Liegt in dem erfindungsgemäßen Textilpflegeprodukt nur ein Copolymer vor, das aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel besteht, beträgt dessen Gesamtmasse ebenfalls vorzugsweise 0,001 Masse% bis 10 Masse% und insbesondere 0,01 Masse% bis 5 Masse%. Bereits eine geringe Gesamtmasse des erfindungsgemäß verwendeten Copolymers von 0,001 Masse%, und insbesondere von 0,01 Masse%, bewirkt eine deutliche Verringerung von Anschmutzungen und eine Verbesserung der Entfernbarkeit von auf das textile Gewebe aufziehenden Anschmutzungen. Es kann somit davon ausgegangen werden, dass bereits eine Gesamtmasse von 0,001 Masse% des erfindungsgemäß zu verwendenden Copolymers zur Ausbildung einer das Gewebe schützenden Soil-Release Schutzschicht führt, die sich durch eine schmutzabweisende Wirkung auszeichnet. Je höher dabei der Anteil an aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehendem Copolymer ist, desto großflächiger und homogener wird diese Schutzschicht auf der Gewebeoberfläche ausgebildet. Anschmutzungen können somit besonders effektiv reduziert oder sogar verhindert werden, wenn die Gesamtmasse dieses Copolymers 0,01 Masse% bis 5 Masse% beträgt. Das Wirkungsspektrum ist in diesem Beriech besonders ausgewogen. Höhere Gesamtmassen von mehr als 5 Masse% oder sogar von mehr als 10 Masse% sind im Hinblick auf die Kosten des Textilpflegeprodukts nachteilig, wobei insbesondere ab einer Gesamtmasse von mehr als 10 Masse% des Copolymers keine wesentliche Steigerung der schmutzabweisenden Wirkung und auch keine weitere Verbesserung der Entfernbarkeit von Anschmutzungen bemerkbar ist. Vielmehr können bei derart hohen Gehalten an aus N- Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehendem Copolymer die haptischen Eigenschaften des Textils beeinträchtigt werden. An advantageous development of the textile care product according to the invention is characterized in that the total mass of copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent, based on the total mass of the fabric care product, 0.001 mass% to 10 mass%, especially 0.01 mass% is up to 5% by weight and especially 1% by weight. If a plurality of copolymers comprising N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent are used in combination, the total mass refers to the total mass of all copolymers comprised of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent in the fabric care product. In other words, if two copolymers composed of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent are used in combination, their total mass is 0.001 mass% to 10 mass%. If only one copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent is present in the textile care product according to the invention, its total mass is also preferably 0.001 mass% to 10 mass% and in particular 0.01 mass% to 5 mass%. Already a small total mass of the copolymer used according to the invention of 0.001% by weight, and in particular of 0.01% by weight, causes a significant reduction in soiling and an improvement in the removability of stains that accumulate on the textile fabric. It can therefore be assumed that even a total mass of 0.001% by weight of the copolymer to be used according to the invention leads to the formation of a fabric-protecting soil release protective layer, which is distinguished by a dirt-repellent effect. The higher the proportion of copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent, the larger and more homogeneous this protective layer is formed on the fabric surface. Soiling can be particularly effectively reduced or even prevented if the total mass of this copolymer 0.01 mass% to 5 mass%. The spectrum of action is particularly balanced in this area. Higher total masses of more than 5% by mass or even more than 10% by mass are disadvantageous in terms of the cost of the fabric care product, in particular from a total mass of more than 10% by mass of the copolymer, no substantial increase of the soil-repellent effect and no further improvement the removability of stains is noticeable. On the contrary, at such high levels of copolymer consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent, the haptic properties of the textile can be impaired.
Gemäß einer vorteilhaften Weiterbildung enthält das Textilpflegeprodukt mindestens ein Tensid. Das Tensid verbessert das Entfernen von Anschmutzungen. Der Zusatz eines oder mehrerer Tenside ist insbesondere dann von Vorteil, wenn das Textilpflegeprodukt in Form eines Waschmittels, wie beispielsweise einem Vollwaschmittel, einem Feinwaschmittel oder einem Spezialwaschmittel, vorliegt. According to an advantageous development, the textile care product contains at least one surfactant. The surfactant improves the removal of stains.

Gemäß einer weiteren vorteilhaften Weiterbildung ist, um eine besonders gute Waschleistung mit hoher Schmutzablösekraft zu erhalten, vorgesehen, dass die Gesamtmasse an Tensid, also die Gesamtmasse an einem oder mehreren Tensiden, bezogen auf die Gesamtmasse des Textilpflegeprodukts, 1 Masse% bis 50 Masse% und insbesondere 3 Masse% bis 20 Masse% beträgt. Bei der Verwendung einer Kombination aus zwei oder mehreren Tensiden bezieht sich die Gesamtmasse an Tensid auf die Gesamtmasse aller eingesetzten Tenside. Weiter vorzugsweise liegt das Textilpflegeprodukt pulverförmig, flüssig, gelförmig, in Form von Tabs oder Kapseln vor. Hierbei ist die flüssige Form besonders bevorzugt, da in flüssigen Textilpflegeprodukten das aus N-Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel bestehende Copolymer hydratisiert und damit insbesondere in Form eines Hydrogels vorliegt, das besonders leicht auf Textilien aufziehen und eine schmutzabweisende Schutzschicht bilden kann.

When using a combination of two or more surfactants, the total amount of surfactant refers to the total mass of all surfactants used. Further preferably, the fabric care product is powdery, liquid, gel, in the form of tabs or capsules. In this case, the liquid form is particularly preferred since in liquid textile care products consisting of N-Isopropylacrylamideinheiten, methacrylic acid units and optionally at least one crosslinking agent hydrated and thus in particular in the form of a hydrogel, which is particularly easy to apply to textiles and can form a dirt-repellent protective layer.

The fabric care product may contain other common ingredients. All amounts stated in connection with the ingredients of the fabric care product described herein are, unless otherwise stated, to mass%, in each case based on the total mass of the fabric care product.
Des Weiteren beziehen sich derartige Mengenangaben, die sich auf mindestens einen Inhaltsstoff beziehen, immer auf die Gesamtmenge dieser Art von Inhaltsstoff, die im Textilpflegeprodukt enthalten ist, sofern nicht explizit etwas anderes angegeben ist.

„Mindestens ein“, wie hierin verwendet, bezieht sich auf 1 oder mehr, beispielsweise 1 , 2, 3, 4, 5, 6, 7, 8, 9 oder mehr. Im Zusammenhang mit Inhaltsstoffen des hierin beschriebenen Textilpflegeprodukts bezieht sich diese Angabe nicht auf die absolute Menge an Molekülen, sondern auf die Art des Bestandteils.„Mindestens ein Enzym“ oder„mindestens eine oberflächenaktive Substanz“ bedeutet daher beispielsweise ein oder mehrere verschiedene Enzyme oder oberflächenaktive Substanzen, d.h. eine oder mehrere verschiedene Arten von Enzymen oder oberflächenaktiven Substanzen. Zusammen mit Mengenangaben beziehen sich die Mengenangaben auf die Gesamtmenge der entsprechend bezeichneten Art von Bestandteil, wie bereits oben definiert. "At least one" as used herein refers to 1 or more, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In the context of ingredients of the fabric care product described herein, this indication does not refer to the absolute amount of molecules but to the nature of the ingredient. "At least one enzyme" or "at least one surfactant" therefore means, for example, one or more different enzymes or surfactants ie one or more different types of enzymes or surfactants. Together with quantities, the quantities refer to the total amount of the corresponding designated type of ingredient as defined above.

Das erfindungsgemäße Textilpflegeprodukt kann ein oder mehrere Enzyme enthalten. Prinzipiell sind diesbezüglich alle im Stand der Technik für diese Zwecke etablierten Enzyme einsetzbar.

Bevorzugte hydrolytische Enzyme umfassen insbesondere Proteasen, Amylasen, insbesondere «-Amylasen, Lipasen, insbesondere Pektinase, Mannanase, FGIukanasen, sowie deren Gemische. Diese Enzyme sind im Prinzip natürlichen Ursprungs. Ausgehend von den natürlichen Molekülen stehen für den Einsatz in Textilpflegeprodukten verbesserte Derivate zur Verfügung, die entsprechend bevorzugt eingesetzt werden. Ferner erfindungsgemäß wird auch ein Verfahren zur Ausrüstung von Textilien mit einer Soil-Release Schutzschicht beschrieben, das die nachfolgenden Verfahrensschritte umfasst: The fabric care product of the invention may contain one or more enzymes. In principle, all the enzymes established in the prior art for this purpose can be used in this regard. Preferably, it is one or more enzymes which can develop a catalytic activity in a fabric care product, in particular a protease, cellulase, amylase, lipase, mannanase, pectin-splitting enzyme, tannase, xylanase, xanthanase, FGuukosidase, carrageenase, perhydrolase , Oxidase, oxidoreductase and their mixtures. Preferred hydrolytic enzymes include in particular proteases, amylases, in particular α-amylases, lipases, in particular pectinase, mannanase, FGIukanases, and mixtures thereof. These enzymes are basically of natural origin. Starting from the natural molecules, improved derivatives are available for use in textile care products, which are preferably used accordingly. Furthermore, according to the invention, a process for finishing textiles with a soil release protective layer is described which comprises the following process steps:
a. Bereitstellen eines wie vorstehend definierten Textilpflegeprodukts und a. Providing a fabric care product as defined above and
b. In-Kontakt-Bringen eines Textils mit dem Textilpflegeprodukt. b. Contacting a textile with the fabric care product.
Das Textilpflegeprodukt kann hierzu in Form einer Lösung (Waschflotte) zubereitet werden, um das Kontaktieren mit dem Textil zu erleichtern. Durch Anwendung oder Ausführung des erfindungsgemäßen Verfahrens werden die erfindungsgemäß behandelten Textilien mit einer Art schmutzabweisender Schutzschicht versehen, die Anschmutzungen effektiv reduziert oder gar verhindert und ein Entfernen von auf das Textil aufziehenden Anschmutzungen oder Wiederanschmutzungen erleichtert und damit verbessert. For this purpose, the textile care product can be prepared in the form of a solution (wash liquor) in order to facilitate contact with the textile. By applying or carrying out the method according to the invention, the textiles treated according to the invention are provided with a type of dirt-repellent protective layer which effectively reduces or even prevents soiling and facilitates removal of stains or repellencies that accumulate on the textile and thus improves.
Es wird angenommen, dass Anschmutzungen durch das Verfahren daran gehindert werden in die Textilien einzudringen und allenfalls an deren Oberfläche, und hier insbesondere auf der Schutzschicht oder dem Schutzfilm, verbleiben. Sie können von dort sehr leicht entfernt werden, beispielsweise indem sie mit einem Teil der Schutzschicht oder auch mit der gesamten Schutzschicht heruntergelöst, und hierbei insbesondere ausgewaschen, werden. Ein Auswaschen wird insbesondere durch die hydrophilen Anteile des Copolymers, also insbesondere die Methacrylsäureeinheiten, begünstigt. Das Verfahren ist einfach und ohne hohen technischen Aufwand umsetzbar und schützt die behandelten Textilien vor Verschmutzung. Hierbei werden die vorteilhaften Effekte für unterschiedliche Textilarten (zum Beispiel Baumwolle-basierte Textilien, Polyamid-basierte Textilien, Polyester-basierte Textilien und jegliche Art von Mischgewebe) sowie für unterschiedliche Anschmutzungen (hydrophile und hydrophobe Anschmutzungen) erzielt. It is believed that stains caused by the process are prevented from penetrating into the textiles and at most remaining on their surface, and in particular on the protective layer or protective film. They can be removed from there very easily, for example, by being dissolved with a part of the protective layer or even with the entire protective layer, and in this case in particular washed out. Washing out is promoted in particular by the hydrophilic fractions of the copolymer, that is to say in particular the methacrylic acid units. The process is simple and can be implemented without great technical effort and protects the treated textiles from contamination. Here are the beneficial effects for different types of textile (for example, cotton-based textiles, polyamide-based textiles, polyester-based textiles and any type of blended fabric) and for different stains (hydrophilic and hydrophobic soiling) achieved.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung wird auch die Verwendung eines wie vorstehend offenbarten Textilpflegeprodukts zur Verringerung einer Wiederanschmutzung von Textilien und zur Verbesserung des Entfernens von Anschmutzungen aus Textilien beschrieben. Diese Effekte werden durch das im erfindungsgemäßen Textilpflegeprodukt vorliegende Copolymer, das aus N- Isopropylacrylamideinheiten, Methacrylsäureeinheiten und optional mindestens einem Vernetzungsmittel besteht, für unterschiedliche Textilarten (zum Beispiel Baumwolle-basierte Textilien, Polyamid-basierte Textilien, Polyester-basierte Textilien und Mischgewebe) und unterschiedliche Anschmutzungen erzielt. Beispiele According to another aspect of the present invention, there is also described the use of a fabric care product as disclosed above to reduce textile repellency and improve the removal of fabric soils. These effects are exhibited by the copolymer present in the fabric care product of the invention consisting of N-isopropylacrylamide units, methacrylic acid units and optionally at least one crosslinking agent for different types of textile (for example cotton-based textiles, polyamide-based textiles, polyester-based textiles and blended fabrics) and different Pollutions achieved.
