Die Erfindung betrifft einen Scheuerkörper, umfassend ein textiles Flächengebilde, welches mit einer Scheuermittel-Zusammensetzung versehen ist, wobei die Scheuermittel-Zusammensetzung einen Binder und Scheuerpartikel umfasst, wobei das textile Flächengebilde eine Reinigungsfläche mit einem Reliefmuster aufweist.The invention relates to a scouring body comprising a fabric provided with a scouring composition, the scouring composition comprising a binder and scouring particles, the fabric comprising a cleaning surface having a relief pattern.
Stand der TechnikState of the art
Aus der DE 298 02 421 U1 ist ein Scheuerkörper bekannt, der als Trägermaterial ein textiles Flächengebilde aufweist, welches mit einer Scheuermittel-Zusammensetzung versehen ist. Das textile Flächengebilde besteht aus einem Vliesstoff, der mechanisch durch Nadeln oder durch Wasserstrahl verfestigt wurde. Auf das Flächengebilde ist eine Scheuermittel- Zusammensetzung aufgebracht, die einen chemischen Binder und abrasive Partikel umfasst. Der vorbekannte Scheuerkörper eignet sich zum Aufnehmen oder Aufsaugen von wässrigen Substanzen und dem Lösen fest anhaftender Verschmutzungen aufgrund der abrasiven Wirkung der Scheuermittel- Zusammensetzung. Bei einem dünnen, flexibel ausgebildeten Scheuerkörper ist nachteilig, dass bei diesen durch eingeschränkte Griffmöglichkeiten, die Kraftübertragung eingeschränkt ist. Des Weiteren erfolgt die Kraftübertragung vorwiegend nur an der Stelle, an der auf den Scheuerkörper Druck ausgeübt wird.From DE 298 02 421 U1 a scouring body is known, which has as a carrier material a textile fabric, which is provided with a scouring composition. The textile fabric consists of a nonwoven fabric which has been mechanically consolidated by needling or by water jet. Applied to the sheet is a scouring composition comprising a chemical binder and abrasive particles. The previously known scouring body is suitable for absorbing or absorbing aqueous substances and for loosening firmly adhering soiling due to the abrasive action of the scouring agent composition. In a thin, flexible trained scouring body is disadvantageous that in these by limited grip options, the power transmission is limited. Furthermore, the power transmission takes place predominantly only at the point at which pressure is exerted on the scrubbing body.

Der Erfindung liegt die Aufgabe zugrunde, einen Scheuerkörper mit einer effektiveren Kraftübertragung bereitzustellen.The invention has for its object to provide a scouring body with a more effective power transmission.
Diese Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved with the features of claim 1. In advantageous embodiments, the dependent claims relate.
Zur Lösung der Aufgabe ist das Flächengebilde auf einem Schwammkörper angeordnet. Das textile Flächengebilde ist dabei als Vliesstoff aus Kunstfasern ausgebildet und vorzugsweise mittels Wasserstrahl verfestigt. Die Dicke des Flächengebildes liegt zwischen 0,8 und 3 mm und das Flächengewicht beträgt zwischen 50 und 200 g/mm2. Derartige Flächengebilde weisen ein geringes Flächengewicht und eine geringe Dicke bei gleichzeitig hoher Zugfestigkeit auf. Der Schwammkörper bildet einen Tragkörper der eine Vielzahl vonTo solve the problem, the fabric is arranged on a sponge body. The textile fabric is formed as a nonwoven fabric made of synthetic fibers and preferably solidified by means of water jet. The thickness of the sheet is between 0.8 and 3 mm and the basis weight is between 50 and 200 g / mm 2 . Such fabrics have a low basis weight and a small thickness with high tensile strength. The sponge body forms a supporting body of a variety of
Griffmöglichkeiten bietet. Dadurch kann auf verschiedene Weise effektiv Kraft auf das mit der Scheuermittel-Zusammensetzung versehene Flächengebilde ausgeübt werden, so dass sich eine gute Reinigungsleistung gegenüber fest anhaftenden Verschmutzungen ergibt. Das Reliefmuster verbessert die Reinigungswirkung des Scheuerkörpers zusätzlich. Dabei kann dasOffers grip options. As a result, in various ways, effective force can be exerted on the fabric provided with the scouring composition so that a good cleaning performance against firmly adhering contaminants results. The relief pattern additionally improves the cleaning action of the scrubbing body. It can do that
Reliefmuster durch eine Noppenstruktur gebildet sein, wobei die Noppen hexagonal angeordnet sind. Dadurch kann vermieden werden, dass der Schmutz die abrasive Fläche zusetzt, da sich der Schmutz zwischen den Noppen in den Vertiefungen sammelt und dadurch den Scheuerprozess nicht beeinflusst. Der Schwammkörper kann aus einem offenzelligen Kunststoffschaum oder einem Naturschaum gebildet sein. Der Schaum kann dabei insbesondere aus Polyurethan oder Viskose gebildet sein. Schäume aus diesen Werkstoffen sind kostengünstig herstellbar und weisen gute mechanische Eigenschaften auf, so dass sie gut greifbar sind und Kräfte übertragen können. Viskose hat eine hohe Wasseraufnahmefähigkeit.Relief pattern may be formed by a nub structure, wherein the nubs are arranged hexagonally. This will prevent the dirt from adding to the abrasive surface as the dirt collects between the dimples in the recesses, thereby not affecting the scrubbing process. The sponge body may be formed of an open-cell plastic foam or a natural foam. The foam can be formed in particular of polyurethane or viscose. Foams made of these materials are inexpensive to produce and have good mechanical properties, so that they are easy to grasp and can transmit forces. Viscose has a high water absorption capacity.
Auf dem Schwammkörper kann ein weiteres textiles Flächengebilde angeordnet sein. Der Scheuerkörper ist vorzugsweise quaderförmig ausgebildet und weist zwei Hauptflächen auf. Dann ist auf einer ersten Hauptfläche das Flächengebilde mit der Scheuermittel-Zusammensetzung angeordnet. Auf der der ersten Hauptflächen gegenüber liegenden zweiten Hauptfläche ist das weitere textile Flächengebilde angeordnet. Dieses Flächengebilde besteht vorzugsweise ebenfalls aus einem Vliesstoff mit Kunststofffasern, wobei der Vliesstoff so ausgebildet ist, dass das weitere Flächengebilde eine hohe Wasseraufnahme aufweist. Die zweite Hauptfläche dient dann der Nachbehandlung von Oberflächen, die bereits mit der ersten Hauptfläche gereinigt wurden und zur Aufnahme von Flüssigkeiten.On the sponge body, another textile fabric may be arranged. The scrubbing body is preferably cuboid and has two major surfaces. Then, on a first major surface, the sheet with the abrasive composition is disposed. On the second main surface opposite the first main surfaces, the further textile fabric is arranged. This sheet preferably also consists of a nonwoven fabric with synthetic fibers, wherein the nonwoven fabric is formed so that the further fabric has a high water absorption. The second main surface then serves for the aftertreatment of surfaces which have already been cleaned with the first main surface and for the absorption of liquids.
Das weitere Flächengebilde kann Mikrofasern umfassen. Mikrofasern weisen einen Faserdurchmesser auf, der kleiner als 1 μm ist. Die zum Einsatz gelangenden Flächengebilde aus Mikrofasern weisen eine hohe Aufnahmefähigkeit für Flüssigkeiten wie Wasser und Fette auf.The further fabric may comprise microfibers. Microfibers have a fiber diameter smaller than 1 μm. The microfibers used have a high absorption capacity for liquids such as water and fats.
Die Scheuermittel-Zusammensetzung kann Glasgranulat umfassen. Glasgranulat weist eine hohe Härte auf und eignet sich besonders zur Reinigung von Glas- oder Keramikoberflächen, wie beispielsweise Glaskeramik-Kochfeldern oder Scheiben von Kaminöfen. 57The scouring composition may comprise glass granules. Glass granules have a high hardness and are particularly suitable for cleaning glass or ceramic surfaces, such as glass ceramic cooktops or slices of stoves. 57
Der Binder kann latex, phenolharz- und/oder acrylatbasiert sein. Ein phenolharzbasierter Binder weist eine hohe Härte eine hohe Abriebsfestigkeit auf. In einer anderen Ausgestaltung kann der Binder acrylatbasiert sein. Acrylatbasierte Binder weisen einen angenehmen Griff auf. Latexbasierte Binder weisen eine hohe Elastizität auf. Mischungen aus Latex- undThe binder may be latex, phenolic resin and / or acrylate based. A phenolic resin-based binder has high hardness, high abrasion resistance. In another embodiment, the binder may be acrylate-based. Acrylate-based binders have a pleasant feel. Latex-based binders have a high elasticity. Mixtures of latex and
Phenolharz-Binder weisen durch das Phenolharz eine hohe Biegesteifigkeit, wobei die Biegesteifigkeit durch den Latex-Anteil so weit herabgesetzt ist, dass der Scheuerkörper gut ausgewrungen werden kann. In einer weiteren Ausgestaltung kann der Binder aus einer Mischung aus Acrylat und Phenolharz bestehen. Die Eigenschaften beider Binder-Stoffe beeinflussen dann den Griff und die Härte des Materials. Dabei kann der Binder auf dem Flächengebilde so ausgebildet sein, dass das Flächengebilde im Wesentlichen wasserundurchlässig ist. Dadurch verbleibt beim Reinigen ein Film aus Reinigungsflüssigkeit zwischen dem Flächengebilde mit der Scheuermittel- Zusammensetzung und der zu reinigenden Oberfläche. Verschmutzungen werden in der Reinigungsflüssigkeit gelöst und es ergibt sich eine schonende und effektive Reinigung der zu reinigenden Oberfläche. Der Binder kann auch so ausgebildet sein, dass das Flächengebilde biegesteif ist. Dadurch ergibt sich eine besonders gute Kraftübertragung und eine verbesserte Reinigungswirkung gegenüber fest anhaftenden Verschmutzungen. Weitere mögliche Binder sind Melaminharz, Nitrilkautschuk, Polyurethan oder Verbindungen aus allen genannten Bindern.Phenol resin binders have a high flexural rigidity due to the phenolic resin, whereby the flexural rigidity is reduced so much by the latex content that the abrasive body can be wrung out well. In a further embodiment, the binder may consist of a mixture of acrylate and phenolic resin. The properties of both binder materials then influence the feel and hardness of the material. In this case, the binder may be formed on the sheet such that the sheet is substantially impermeable to water. As a result, when cleaning, a film of cleaning liquid remains between the fabric having the abrasive composition and the surface to be cleaned.

Der Schwammkörper kann viereckig ausgebildet sein, wobei die Kanten eine geschwungene Kontur aufweisen. Dadurch können schwer erreichbare Stellen effektiv gereinigt werden. Es ergibt sich eine Vielzahl verschiedener Griffmöglichkeiten.The sponge body may be formed quadrangular, wherein the edges have a curved contour. As a result, hard to reach areas can be effectively cleaned. It results in a variety of different grip options.
Die einander gegenüber liegenden Kanten können zueinander kongruent ausgebildet sein. Der Scheuerkörper wird meist aus einem flächigen Vorprodukt durch Ausstanzen hergestellt. Bei dieser Formgebung ergibt sich eine verlustfreie und dadurch kostengünstige Herstellung von Scheuerkörpern mit geschwungener Kantengestaltung.The mutually opposite edges may be formed congruent to each other. The scouring body is usually made of a flat Precursor produced by punching. In this shaping results in a lossless and therefore cost-effective production of abrasive bodies with curved edge design.
