Description

Die Erfindung betrifft ein Verfahren zum Reinigen und/oder Konditionieren von textilen Flächengebilden, bei dem die feuchten, zu reinigenden und/oder zu konditionierenden textilen Flächengebilde mit einer Formulierung, enthaltend wenigstens einen Polymerkörper und eine Waschmittelzusammensetzung in Kontakt gebracht werden. Die Erfindung betrifft auch ein Kit, umfassend Inhaltsstoffe der Formulierung.The invention relates to a process for cleaning and / or conditioning fabrics, in which the wet, to be cleaned and / or conditioned fabrics are brought into contact with a formulation containing at least one polymer body and a detergent composition. The invention also relates to a kit comprising ingredients of the formulation.

Die Reinigung und/oder Konditionierung von textilen Flächengebilden mit wenig oder gar ohne Wasser oder ohne große Mengen an organischen Lösungsmitteln ist nicht nur interessant für institutionelles Waschen, sondern gewinnt aufgrund der wertvollen Ressource Wasser immer mehr an Bedeutung.The cleaning and / or conditioning of textile fabrics with little or no water or without large amounts of organic solvents is not only interesting for institutional washing, but due to the valuable resource of water is becoming increasingly important.

Aus der WO 2007/128962 A1 ist ein Waschverfahren bekannt, welches die Behandlung von verschmutzter Wäsche durch Inkontaktbringen der Wäsche mit einer Formulierung, umfassend eine Vielzahl an Polymerpartikel umfasst.From the WO 2007/128962 A1 For example, a washing process is known which comprises treating soiled laundry by contacting the laundry with a formulation comprising a plurality of polymer particles.

Es besteht allerdings weiter Bedarf, Maßnahmen bereit zustellen, die die Fleckentfernung in einem solchen Verfahren weiter verbessern.However, there is still a need to provide measures that further improve stain removal in such a process.

Diese Aufgabe wird gelöst durch ein Verfahren zum Reinigen und/oder Konditionieren von textilen Flächengebilden, bei dem die feuchten, zu reinigenden und/oder zu konditionierenden textilen Flächengebilde mit einer Formulierung, enthaltend

  1. a) wenigstens einen Polymerkörper, wie in Anspruch 1 definiert,
  2. b) eine Waschmittelzusammensetzung und
  3. c) Wasserstoffperoxid (H2O2) in Kontakt gebracht werden.
This object is achieved by a method for cleaning and / or conditioning of textile fabrics, wherein the moist, to be cleaned and / or conditioned fabrics with a formulation containing
  1. a) at least one polymer body as defined in claim 1,
  2. b) a detergent composition and
  3. c) bringing hydrogen peroxide (H 2 O 2 ) into contact.

Ferner hat sich gezeigt, dass der Polymerkörper nach Beendigung des Wasch- und/oder Konditionierungsverfahren auf seiner Oberfläche weniger stark eingefärbt bzw. verschmutzt ist. Durch das deutlich sauberere Aussehen des Polymerkörpers hat der Verbraucher deutlich weniger Hemmungen, den Polymerkörper mehrfach zu verwenden.It has also been shown that the polymer body is less strongly colored or soiled on its surface after completion of the washing and / or conditioning process. Due to the much cleaner appearance of the polymer body, the consumer has significantly fewer inhibitions to use the polymer body multiple times.

Der Polymerkörper enthält ein Polymer ausgewählt aus der Gruppe der Polyalkylene, der Polyamide und Mischungen daraus.The polymer body contains a polymer selected from the group of polyalkylenes, polyamides and mixtures thereof.

Diese Polymere eignen sich zum Einsatz in einem solchen, wasserarmen Waschverfahren und sind vor allem auch kompatibel mit H2O2.These polymers are suitable for use in such a low-water washing process and, above all, are also compatible with H 2 O 2 .

Polymerkörper aus Polyalkylenen eignen sich besonders zur Entfernung von ÖI-basierten Flecken.Polyalkylenes polymer bodies are particularly suitable for the removal of oil-based stains.

Bei dem erfindungsgemäßen Verfahren ist ein Spülgang nicht erforderlich. Dass heißt im Umkehrschluss, dass viele Inhaltsstoffe des Waschmittels auf den textilen Flächengebilden verbleiben. Um eine Sensibilisierung und allergische Reaktionen, hervorgerufen durch Enzyme zu vermeiden, kann es vorteilhaft sein, dass die Waschmittelzusammensetzung frei von Enzymen ist.In the method according to the invention, a rinse cycle is not required. This means, conversely, that many ingredients of the detergent remain on the textile fabrics.

Aus Kostengründen ist es vorteilhaft, dass H2O2, welches verglichen mit anderen Bleichmitteln wie Percarbonaten oder Perboraten ein preiswertes Bleichmittel ist, in dem Verfahren eingesetzt werden kann. Zudem wird Wasserstoffperoxid in wässriger Lösung eingesetzt, so dass sich das Bleichmittel während des Waschprozesses nicht erst lösen muss. Außerdem verteilt es sich dadurch gleichmäßiger in der Formulierung.For cost reasons, it is advantageous that H 2 O 2 , which is an inexpensive bleaching agent compared to other bleaching agents such as percarbonates or perborates, can be used in the process. In addition, hydrogen peroxide is used in aqueous solution, so that the bleaching agent does not have to dissolve during the washing process. It also distributes it more evenly in the formulation.

Die Erfindung betrifft auch ein Kit zum Reinigen und/oder Konditionieren von textilen Flächengebilden, umfassend

  1. a) wenigstens einen Polymerkörper, wie in Anspruch 8 definiert,
  2. b) eine Waschmittelzusammensetzung und
  3. c) Wasserstoffperoxid (H2O2).
The invention also relates to a kit for cleaning and / or conditioning textile fabrics, comprising
  1. a) at least one polymer body as defined in claim 8,
  2. b) a detergent composition and
  3. c) hydrogen peroxide (H 2 O 2 ).

Im Folgenden soll die Erfindung unter anderem anhand von Beispielen eingehender beschrieben werden.In the following, the invention will be described in more detail, inter alia, by way of examples.

Das erfindungsgemäße Verfahren kann bei einer großen Vielzahl an textilen Flächengebilden angewendet werden. Es kann beispielsweise bei allen natürlichen und synthetischen Gewebefasern eingesetzt werden, obwohl es besonders vorteilhaft bei Geweben aus PA 66, Polyester und Baumwolle angewendet wird.The method according to the invention can be applied to a large number of textile fabrics. It can be used, for example, in all natural and synthetic fabric fibers although it is most advantageously used on fabrics made of PA 66, polyester and cotton.

Es ist vorteilhaft, dass die zu behandelnden Gewebe mit Wasser befeuchtet werden, um insbesondere den Transport von Schmutzpartikeln zum Polymerkörper zu verbessern. Sind das H2O2 und/oder die Waschmittelzusammensetzung auf dem Polymerkörper aufgebracht und/oder vom Polymerkörper absorbiert, wird durch das Anfeuchten der textilen Flächengebilde auch der Transport vom H2O2 und/oder den Inhaltsstoffen der Waschmittelzusammensetzung vom Polymerkörper auf die textilen Flächengebilde verbessert. Das Anfeuchten der textilen Flächengewebe kann beispielsweise durch Benetzung mit Wasser oder einer wässrigen Lösung der Waschmittelmittelzusammensetzung erfolgen.It is advantageous that the tissues to be treated are moistened with water, in particular to improve the transport of dirt particles to the polymer body. When the H 2 O 2 and / or the detergent composition is applied to the polymer body and / or absorbed by the polymer body, the wetting of the fabric also causes the transport of H 2 O 2 and / or the detergent composition ingredients from the polymer body to the fabrics improved. The moistening of the textile surface fabrics can be carried out, for example, by wetting with water or an aqueous solution of the detergent composition.

Die Menge an Wasser, die vorteilhafter Weise eingesetzt wird, hängt auch von der Wasseraufnahmekapazität der textilen Flächengebilde ab. Es ist jedoch im Allgemeinen bevorzugt, dass das Gewichtsverhältnis textile Flächengebilde zu Wasser von 1 : 0,1 bis 1 : 5 und mehr bevorzugt von 1 : 0,2 bis 1 : 2 beträgt.The amount of water that is used advantageously also depends on the water absorption capacity of the textile fabrics. However, it is generally preferred that the weight ratio of fabric to water is from 1: 0.1 to 1: 5, and more preferably from 1: 0.2 to 1: 2.

In dem Verfahren wird wenigstens ein Polymerkörper eingesetzt. Es ist aber aus Gründen der Effizienz des Verfahrens bevorzugt, wenn in dem Verfahren eine Vielzahl an Polymerkörpern eingesetzt wird.

Diese Formen gewährleisten eine gute Beweglichkeit des Polymerkörpers und einen engen Kontakt mit den textilen Flächengebilden.The polymer body may be of any shape, but is preferably in the form of a chip, sphere, cube, ice, cylinder, disk, cuboid or truncated cone. These shapes ensure good mobility of the polymer body and close contact with the fabrics.

Die maximale räumliche Ausdehnung des Polymerkörpers liegt vorzugsweise im Bereich von 1 bis 10 mm und mehr bevorzugt im Bereich von 2 bis 6 mm. Der Begriff "maximale räumliche Ausdehnung" bezeichnet in diesem Zusammenhang den Abstand zwischen den zwei am weitesten voneinander entfernten Punkte auf dem Polymerkörper.The maximum spatial extent of the polymer body is preferably in the range of 1 to 10 mm, and more preferably in the range of 2 to 6 mm.

Die angegebenen Ethoxylierungsgrade stellen statistische Mittelwerte dar, die für ein spezielles Produkt eine ganze oder eine gebrochene Zahl sein können. Bevorzugte Alkoholethoxylate weisen eine eingeengte Homologenverteilung auf (narrow range ethoxylates, NRE). Zusätzlich zu diesen nichtionischen Tensiden können auch Fettalkohole mit mehr als 12 EO eingesetzt werden. Beispiele hierfür sind Talgfettalkohol mit 14 EO, 25 EO, 30 EO oder 40 EO. Auch nichtionische Tenside, die EO- und PO-Gruppen zusammen im Molekül enthalten, sind erfindungsgemäß einsetzbar. Geeignet sind ferner auch eine Mischung aus einem (stärker) verzweigten ethoxylierten Fettalkohol und einem unverzweigten ethoxylierten Fettalkohol, wie beispielsweise eine Mischung aus einem C16-18-Fettalkohol mit 7 EO und 2-Propylheptanol mit 7 EO.

Schließt sich dem erfindungsgemäßen Verfahren kein Spülgang an, so ist es bevorzugt, dass die Waschmittelzusammensetzung keine Inhaltsstoffe enthält, die bei Kontakt mit Haut eine Sensibilisierung oder Allergien auslösen können. Deshalb kann es beispielsweise bevorzugt sein, dass die Waschmittelzusammensetzung frei von Enzymen ist.If no rinse is involved in the process of the present invention, it is preferred that the detergent composition contain no ingredients capable of causing sensitization or allergies upon contact with skin. Therefore, for example, it may be preferable for the detergent composition to be free of enzymes.

Die Waschmittelzusammensetzung selber kann fest, flüssig, gelförmig, wachsartig oder pastenförmig sein, wobei flüssige Waschmittel aufgrund der besseren Löseeigenschaften insbesondere bevorzugt sind.The detergent composition itself may be solid, liquid, gel, waxy or pasty, with liquid detergents being particularly preferred due to the improved quenching properties.

Die Waschmittelzusammensetzung kann separat und/oder auf dem Polymerkörper aufgebracht und/oder vom Polymerkörper absorbiert in dem Verfahren eingesetzt werden. Es kann bevorzugt sein, dass der Polymerkörper mit der Waschmittelzusammensetzung beschichtet ist. Wird die Waschmittelzusammensetzung auf dem Polymerkörper aufgebracht und/oder vom Polymerkörper absorbiert in dem Verfahren eingesetzt, erleichtert dies dem Anwender die Durchführung des Verfahrens, da er die Waschmittelzusammensetzung nicht noch separat zu dosieren muss.The detergent composition can be applied separately and / or on the polymer body and / or absorbed by the polymer body in the process. It may be preferred that the polymer body is coated with the detergent composition. When the detergent composition is applied to the polymer body and / or absorbed by the polymer body used in the process, this facilitates the operation of the process for the user since he does not yet have to dose the detergent composition separately.

Neben dem Polymerkörper und der Waschmittelzusammensetzung enthält die Formulierung Wasserstoffperoxid. Wasserstoffperoxid ist ein preiswertes Bleichmittel und hinterlässt keine Rückstände auf den damit behandelten textilen Flächengebilden.In addition to the polymer body and the detergent composition, the formulation contains hydrogen peroxide. Hydrogen peroxide is a cheap bleaching agent and does not leave any residue on the treated textile fabrics.

Das Wasserstoffperoxid kann separat und/oder in der Waschmittelzusammensetzung eingearbeitet und/oder auf dem Polymerkörper aufgebracht und/oder vom Polymerkörper absorbiert in dem Verfahren eingesetzt werden. Ist das Wasserstoffperoxid bereits in Waschmittelzusammensetzung eingearbeitet oder wird auf dem Polymerkörper aufgebracht und/oder vom Polymerkörper absorbiert in dem Verfahren eingesetzt, vermeidet dies, dass der Anwender in direkten Kontakt mit dem Wasserstoffperoxid kommt.The hydrogen peroxide may be incorporated separately and / or in the detergent composition and / or applied to the polymer body and / or absorbed by the polymer body in the process. If the hydrogen peroxide is already incorporated into detergent composition or is applied to the polymer body and / or absorbed by the polymer body in the process, this avoids the user coming into direct contact with the hydrogen peroxide.

Die Menge an H2O2 beträgt vorzugsweise 0,5 bis 10 g und mehr bevorzugt 0,5 bis 3 g pro Waschladung, wobei die Waschladung bis zu 5 kg wiegt.The amount of H 2 O 2 is preferably 0.5 to 10 g and more preferably 0.5 to 3 g per wash load, the wash load weighing up to 5 kg.

Das Verfahren kann in eigens dafür ausgelegten Waschmaschinen durchgeführt werden. Dabei können die eingesetzten Polymerkörper entweder separat durch den Anwender des Verfahrens in die Waschtrommel eingeführt werden oder, in einer alternativen Ausführungsform, in einer Vorratskammer innerhalb der Waschmaschine aufbewahrt und dann zum Waschgang in die Waschtrommel automatisch dosiert werden. Die Polymerkörper können nach Beendigung des Waschverfahrens entweder zusammen mit den gereinigten textilen Flächengebilden entfernt oder in die Vorratskammer für weitere Anwendungen zurückgeführt werden.The process can be carried out in specially designed washing machines. The polymer bodies used can either be introduced separately into the washing drum by the user of the method or, in an alternative embodiment, stored in a storage chamber within the washing machine and then to the wash cycle in the washing machine Wash drum automatically dosed. The polymer bodies may be either removed along with the cleaned fabrics after completion of the washing process or returned to the pantry for other applications.

Bei mehrfacher Anwendung eines Polymerkörpers kann es bevorzugt sein, dass dieser einem Auffrischungsschritt unterzogen werden. Dies kann beispielsweise durch Spülen des Polymerkörpers mit einer Reinigungslösung, um anhaftende Pigmentpartikel zu entfernen und/oder Bleichen der in den äußeren Schichten der Polymerkörper anhaftenden Schmutzpartikel erfolgen. Dieser Auffrischungsschritt kann zum Beispiel automatisch in einer dafür ausgelegten Waschmaschine oder separat erfolgen.When using a polymer body several times, it may be preferable to subject it to a refreshing step. This can be done, for example, by rinsing the polymer body with a cleaning solution in order to remove adhering pigment particles and / or bleaching the dirt particles adhering in the outer layers of the polymer bodies. This refreshing step may for example be done automatically in a dedicated washing machine or separately.

In einer alternativen Ausführungsform kann das Verfahren in einem handelsüblichen Trockner durchgeführt werden. Dazu werden die feuchten, zu reinigenden Textilien zusammen mit dem/den Polymerkörper(n), der Waschmittelzusammensetzung und dem Wasserstoffperoxid in einen Luft-, Wasser- und Wasserdampf-dichten Beutel gegeben und dieser wird anschließend verschlossen in einem Trockner platziert. Nach Beendigung des Trockenprogramms wird der Beutel entnommen und die gereinigten textilen Flächengebilde werden entnommen sowie getrocknet.In an alternative embodiment, the process can be carried out in a commercially available dryer. For this purpose, the moist, to be cleaned textiles together with the / the polymer body (s), the detergent composition and the hydrogen peroxide in an air, water and water vapor-tight bag and this is then placed sealed in a dryer. After completion of the drying program, the bag is removed and the cleaned fabrics are removed and dried.

Bevorzugt wird das erfindungsgemäße Verfahren bei einer Temperatur kleiner 100 °C durchgeführt. Insbesondere bevorzugt wird das Verfahren bei Temperaturen zwischen 30 und 90 °C durchgeführt.The process according to the invention is preferably carried out at a temperature of less than 100.degree.

For this purpose, the Y values of the stained, untreated standard fabrics and the Y values of the stained textiles treated in either method E or V were determined (see Table 2). The determination was carried out at 420 nm (instrument: Datacolor Spectraflash 600, 30 mm aperture). In the case of natural soils, the stain removal was assessed by the dY value (Y value of the untreated spot minus the Y value of the treated stain).

Die Ergebnisse zeigen deutlich, dass durch Zugabe von H2O2 nicht nur eine deutlich verbesserte Fleckentfernung bei bleichbaren Flecken, sondern auch bei einer Vielzahl anderer Flecken auftritt. Außerdem waren die Polyamid-Chips, welche im erfindungsgemäßen Verfahren eingesetzt wurden, deutlich weniger stark verfärbt/angeschmutzt als die Polyamid-Chips, die im Verfahren V eingesetzt wurden.The results clearly show that addition of H 2 O 2 not only results in markedly improved stain removal on bleachable stains, but also on a variety of other stains. In addition, the polyamide chips used in the process according to the invention were much less discolored / soiled than the polyamide chips used in process V.

Außerdem zeigte sich, dass die Schmutzübertragung auf das weiße, nicht angeschmutzte Gewebein dem erfindungsgemäßen Verfahren E deutlich weniger stark war, als im Verfahren V.In addition, it was found that the dirt transfer to the white, not soiled fabric in process E according to the invention was significantly less pronounced than in process V.
