Beschreibung Die Erfindung betrifft ein Reinigungstuch mit einem textilen Trägermaterial und einer darauf angeordneten Beschichtung, bzw. Imprägnierung. Das The invention relates to a cleaning cloth having a textile carrier material and a coating or impregnation thereon. The
Reinigungstuch verbindet in neuartiger Weise gute Reinigungseigenschaften und Gleiteigenschaften mit einer kostengünstigen Herstellung und guter Cleaning cloth combines in a novel way good cleaning properties and sliding properties with a cost-effective production and good

Im Haushalt und in der professionellen Reinigung sind verschiedene Arten von Reinigungstüchern bekannt, die für die Reinigung des Fußbodens oder anderer Flächen dienen. Die Reinigungstücher können einen einfachen Aufbau haben, indem sie beispielsweise aus einem einschichtigen textilen Grundkörper gebildet sind. Wichtig für das Reinigungstuch ist, dass es den Schmutz von der zu reinigenden Fläche gut aufnimmt und beim Auswringvorgang möglichst vollständig wieder abgibt. Zudem ist die Wasseraufnahme und -abgäbe des Tuches wichtig. Wasser wird einerseits zum Anlösen von anhaftendem In the household and in the professional cleaning various types of cleaning cloths are known, which serve for the cleaning of the floor or other surfaces. The cleaning cloths may have a simple structure, for example by being formed from a monolayer textile base body. It is important for the cleaning cloth that it absorbs the dirt from the surface to be cleaned well and returns as completely as possible during the wringing process. In addition, the water absorption and -abgäbe the cloth is important. On the one hand, water is used to dissolve adhering water
Schmutz benötigt, andererseits werden damit der angelöste Schmutz, bzw. lose Schmutzpartikel wie Staub etc. gebunden und mit dem Tuch von der zu reinigenden Oberfläche entfernt. Des Weiteren sind die Gleiteigenschaften des Tuches für den Benutzer wichtig. Hier hat sich gezeigt, dass beim Reinigen großer Flächen (z.B. Fenster, Schultafeln, große Tische, Wände, Dirt is needed, on the other hand so that the loosened dirt or loose dirt particles such as dust etc. are tied and removed with the cloth from the surface to be cleaned. Furthermore, the sliding properties of the cloth are important to the user. It has been found that when cleaning large areas (e.g., windows, blackboards, large tables, walls,
Autokarosserien) das Reinigungstuch eher leicht gleiten sollte, um eine gute Ergonomie und einen geringen Kraftaufwand beim Wischen zu erzielen. Bei kleineren oder stärker verschmutzen Flächen hingegen bevorzugen Benutzer oft Reinigungstücher mit einer höheren Friktion, damit anhaftender Schmutz besser entfernt werden kann, bzw. der Reinigungsvorgang auch haptisch erfassbar ist. Zur Erhöhung der Reinigungsleistung ist es bekannt, textile Trägermaterialien mit einer Beschichtung, bzw. Imprägnierung zu versehen. So können textile Materialien beispielsweise mit einer Polyurethan- (PU-) Beschichtung, bzw. Imprägnierung versehen werden. Die Auftragung der PU-Beschichtungs-, bzw. Imprägnierungsmasse erfolgt dabei nach gängiger Praxis der Art, dass das Substrat in eine Lösung aus PL) und Dimethylformamid (DMF) eingetaucht wird. Car bodies), the cleaning cloth should slide rather easily to achieve a good ergonomics and low effort when wiping. For smaller or more polluted areas, on the other hand, users prefer often wipes with a higher friction, so that adhering dirt can be better removed, or the cleaning process is also haptically detectable. To increase the cleaning performance, it is known to provide textile carrier materials with a coating or impregnation. For example, textile materials can be provided with a polyurethane (PU) coating or impregnation. The application of the PU coating or impregnation mass is carried out according to common practice of the type that the substrate is immersed in a solution of PL) and dimethylformamide (DMF).
Ein weiteres bekanntes Verfahren ist die Beschichtung, bzw. Imprägnierung eines textilen Trägermaterials bestehend aus PVA(Polyvinylalkohol)-Fasern mit einem PVF-Mikroschaum. Dabei kommt es zu einer guten Haftung zwischen den Fasern und dem Beschichtungs-/Imprägnierungs-Material, da während des Beschichtungs-/lmprägnierungsprozesses die Oberfläche der Fasern im wässrigen Medium angelöst wird und eine dauerhafte und waschstabile chemisch-physikalische Oberflächenverbindung zwischen Träger- und Another known method is the coating or impregnation of a textile carrier material consisting of PVA (polyvinyl alcohol) fibers with a PVF microfoam. This results in good adhesion between the fibers and the coating / impregnation material since, during the coating / impregnation process, the surface of the fibers is solubilized in the aqueous medium and a permanent and washable chemical-physical surface bond between support and surface
Beschichtungsmaterial erzielt wird. Coating material is achieved.
Die der Erfindung zu Grunde liegende Aufgabe besteht darin, ein The object of the invention is based, a
Reinigungstuch der eingangs genannten Art bereit zu stellen, welches gute Reinigungseigenschaften mit guten Wasseraufnahme- und Gleiteigenschaften kombiniert und dabei eine gute Waschstabilität aufweist. Mit dem To provide cleaning cloth of the type mentioned, which combines good cleaning properties with good water absorption and sliding properties while having a good wash stability. With the
Reinigungstuch soll ferner eine sehr gute Reinigungswirkung erzielbar sein. Cleaning cloth should also be achieved a very good cleaning effect.
Weiter soll das Reinigungstuch den aufgenommenen Schmutz, insbesondere lose Schmutzpartikel, beim Ausspülen wieder einfach und gut abgeben können. Dadurch kann beispielsweise verhindert werden, dass aufgenommener Sand (z.B. mit Quarzanteilen) beim Reinigen von verchromten/polierten Oberflächen diese zerkratzt oder beschädigt. Zudem soll das Reinigungstuch eine schonende Reinigung von Gegenständen oder Oberflächen ermöglichen. Next is the cleaning cloth the dirt, especially loose dirt particles, when flushing again can easily and easily. This can be prevented, for example, that recorded sand (eg with quartz components) when cleaning chrome-plated / polished surfaces these are scratched or damaged. In addition, the cleaning cloth should allow a gentle cleaning of objects or surfaces.
Schließlich soll die Beschichtung, bzw. Imprägnierung eine ausreichende Haftung zum textilen Trägermaterial zeigen, um eine entsprechende Finally, the coating, or impregnation should show sufficient adhesion to the textile substrate to a corresponding
mechanische Stabilität beim Reinigen und insbesondere bei der maschinellen Wäsche aufzuweisen. Unter hoher Stabilität bei maschineller Wäsche soll erfindungsgemäß verstanden werden, dass bei einem Eltra-Waschverfahren, definiert in dem Bundesgesundheitsblatt - Gesundheitsforschung - Gesundheitsschutz 10, 2007, Seite 1345 bei der Verwendung von 7 g Eitra als Wasch-, und Desinfektionsmittel, einer Desinfektionstemperatur von 60° C, einer Einwirkzeit von 20 min, einem Flottenverhältnis von 1 :5 und einem to have mechanical stability during cleaning and especially during machine washing. Under high stability in machine washing should be understood according to the invention that in an Eltra washing process, defined in the Federal Health Gazette - Health Research - Health Protection 10, 2007, page 1345 when using 7 g of Eitra as detergents and disinfectants, a disinfection temperature of 60 ° C, a contact time of 20 min, a liquor ratio of 1: 5 and a
Wirkungsbereich AB ein Gewichtsverlust des Reinigungstuches von weniger als 5 Gew.% vorliegt. Diese Aufgabe wird erfindungsgemäß gelöst durch ein Reinigungstuch umfassend ein textiles Trägermaterial, welches zumindest teilweise mit einem PVF-Mikroschaum in einer solchen Menge versehen ist, dass der Anteil an PVF-Mikroschaum am Gesamtgewicht des Reinigungstuches weniger als 60 Gew.%, bevorzugt kleiner als 50 Gew.% ist und welches keine PVA-Fasern oder PVA-Fasern in einer Menge von weniger als 50 Gew.% aufweist. Range of action AB a weight loss of the cleaning cloth of less than 5 wt.% Is present. This object is achieved by a cleaning cloth comprising a textile carrier material which is at least partially provided with a PVF microfoam in such an amount that the proportion of PVF microfoam on the total weight of the cleaning cloth less than 60 wt.%, Preferably less than 50 % By weight and which does not have PVA fibers or PVA fibers in an amount of less than 50% by weight.
Das erfindungsgemäße Reinigungstuch zeichnet sich dadurch aus, dass es ein nicht aus PVA-Fasern bestehendes textiles Trägermaterial aufweist, welches mit einem PVF-Mikroschaum versehen ist. Dabei kann der PVF-Mikroschaum als Beschichtung und/oder Imprägnierung vorliegen und Porengrößen unter 00 pm aufweisen. Vorzugsweise liegt der Mikroschaum sowohl als The cleaning cloth according to the invention is characterized in that it has a non-PVA fibers textile substrate, which is provided with a PVF microfoam. In this case, the PVF microfoam may be present as a coating and / or impregnation and have pore sizes below 00 pm. Preferably, the microfoam is both as
Beschichtung als auch als Imprägnierung vor, das heißt dass sowohl die Faserzwischenräume mit PVF-Mikroschaum gefüllt vorliegen als auch eine Deckschicht aus PVF-Mikroschaum vorliegt. Überraschenderweise weist das erfindungsgemäße Reinigungstuch eine hervorragende Waschbeständigkeit auf. Dies ist insofern überraschend als bisher immer davon ausgegangen wurde, dass es für eine hohe Beständigkeit notwendig ist, dass eine PVA-Faser mit einer PVA-Lösung beschichtet, bzw. imprägniert werden muss. Durch die chemische Ähnlichkeit der beiden Coating as well as impregnation before, that is, that both the fiber interstices filled with PVF microfoam present as well as a top layer of PVF microfoam is present. Surprisingly, the cleaning cloth according to the invention has an excellent washing resistance. This is surprising insofar as it has always been assumed that it is necessary for a high resistance that a PVA fiber has to be coated or impregnated with a PVA solution. By the chemical similarity of the two
Materialien sowie durch die teilweise Anlösung der PVA-Faser kommt es nämlich zu einer guten chemischen und mechanischen Verbindung zwischen Faser und Mikroschaum. Aus diesem Grund zeichnet sich das In fact, as a result of the partial dissolution of the PVA fiber, a good chemical and mechanical bond between the fiber and the microfoam results. That's why it stands out
erfindungsgemäße Reinigungstuch durch eine gute mechanische Stabilität beim Reinigen und insbesondere bei der maschinellen Wäsche aus. Cleaning cloth according to the invention by a good mechanical stability during cleaning and in particular in the machine wash.
Praktische Versuche haben aber nun erfindungsgemäß gezeigt, dass auch ein nicht-PVA artiger Trägerstoff wie beispielsweise PP/PES/PA mit PVF eine gute und vor allem waschstabile Verbindung eingehen kann, sofern der Schaum als Mikroschaum vorliegt. Somit kann im erfindungsgemäßen Reinigungstuch der Anteil an PVA, insbesondere an PVA-Fasern geringer als 50 Gew.% oder auch kleiner als 30 Gew.%, oder auch kleiner als 10 Gew.% und insbesondere auch kleiner als 5 Gew.% sein. Das Reinigungstuch kann auch kein PVA, However, practical experiments have now shown according to the invention that a non-PVA-like carrier such as PP / PES / PA with PVF can enter into a good and especially wash stable compound, if the foam is present as microfoam. Thus, in the cleaning cloth according to the invention, the proportion of PVA, in particular of PVA fibers, may be less than 50% by weight or even less than 30% by weight, or even less than 10% by weight and in particular less than 5% by weight. The cleaning cloth can not be PVA,
insbesondere keine PVA-Fasern aufweisen. in particular, have no PVA fibers.
Ohne sich erfindungsgemäß auf einen bestimmten Mechanismus festzulegen wird vermutet, dass die Ausbildung von Spannsegeln innerhalb der Without being bound to a particular mechanism according to the invention it is believed that the formation of tension sails within the
Mikroschaumstruktur einen wesentlichen Anteil für die gute Verbindung des nicht-PVA artigen Trägerstoffs mit der PVF-Beschichtung hat. Micro foam structure has a significant share for the good connection of the non-PVA-like carrier with the PVF coating.
Erfindungsgemäß ist das textile Trägermaterial zumindest teilweise mit einem PVF-Mikroschaum in einer solchen Menge versehen, dass der Anteil an PVF- Mikroschaum am Gesamtgewicht des Reinigungstuches weniger als 50 Gew.% bevorzugt kleiner als 30% ist. Die Einstellung eines derartigen eher geringen Anteils an PVF-Mikroschaum ist deshalb vorteilhaft, weil sich gezeigt hat, dass hierdurch der textile und weiche Griff des finalen Reinigungstuches weitgehend erhalten werden kann, obwohl der PVF-Mikroschaum die Eigenschaft besitzt, im trockenen Zustand an Weichheit zu verlieren und damit zu einem According to the invention, the textile carrier material is at least partially provided with a PVF microfoam in such an amount that the proportion of PVF microfoam in the total weight of the cleaning cloth is less than 50% by weight, preferably less than 30%. The adjustment of such a rather low proportion of PVF microfoam is advantageous because it has been shown that As a result, the textile and soft feel of the final cleaning cloth can be largely preserved, although the PVF microfoam has the property of losing softness in the dry state and thus to a
weitgehend biegeharten Reinigungstuch führt. largely bending cleansing wipe leads.
Praktische Versuche haben ergeben, dass es für die Haftung des PVF- Mikroschaums am textilen Trägermaterial, beispielsweise dem Vliesstoff, zweckmäßig ist, wenn das Trägermaterial offenporig ausgebildet ist. Dies ist vorteilhaft, da so die zur Herstellung des PVF-Mikroschaums eingesetzte PVA- Lösung das Trägermaterial gut durchdringen und beispielsweise die Practical tests have shown that it is expedient for the adhesion of the PVF microfoam to the textile carrier material, for example the nonwoven fabric, when the carrier material is open-pored. This is advantageous since the PVA solution used for the production of the PVF microfoam penetrates the carrier material well and, for example, the
Vliesfasem, bzw. - filamente allseitig umschließen kann. Fleece fibers, or filaments can enclose on all sides.
Wird ein eher dichtes Trägermaterial eingesetzt, so kann eine gute If a rather dense substrate used, so can a good
Durchdringung des Trägermaterials durch den PVF-Mikroschaum auch dadurch erzielt werden, dass eine PVA-Lösung eingesetzt wird, die eine eher geringe Viskosität aufweist. Der PVF(Pol vinylformal)-Mikroschaum kann wie dem Fachmann bekannt ist durch Umsetzen von PVA mit Formaldehyd gebildet werden. Dabei reduziert sich die Wasserlöslichkeit des PVA. Erfindungsgemäß bevorzugt weist der PVF-Mikroschaum eine Wasserlöslichkeit bei 100°C von weniger als 5 Gew.% auf. Penetration of the substrate by the PVF microfoam can also be achieved by using a PVA solution that has a rather low viscosity. The PVF (Pol vinylformal) microsphere, as known to those skilled in the art, can be formed by reacting PVA with formaldehyde. This reduces the water solubility of the PVA. According to the invention, the PVF microfoam preferably has a solubility in water at 100 ° C. of less than 5% by weight.
Praktische Versuche haben gezeigt, dass das erfindungsgemäße Practical experiments have shown that the inventive
Reinigungstuch neben seiner hohen Waschstabilität gute Cleaning cloth good in addition to its high wash stability
Reinigungseigenschaften mit guten Wasseraufnahme- und Gleiteigenschaften kombiniert. Gleichzeitig wird eine gute Ausspülbarkeit des aufgenommenen Schmutzes aus dem Tuch erreicht. Cleaning properties combined with good water absorption and sliding properties. At the same time a good flushability of the collected dirt is achieved from the cloth.
Es ist denkbar, dass das textile Trägermaterial zumindest anteilig aus einem Mikrofaser-Material besteht. Diese Ausführungsform kann für manche It is conceivable that the textile carrier material consists at least proportionally of a microfiber material. This embodiment may be for some
Anwendungen zweckmäßig sein, da auch bei der Verwendung von Fasern aus einem hydrophoben Material wegen der Kapillar-Wirkung der gewirkten Applications should be appropriate, as well as in the use of fibers a hydrophobic material because of the capillary action of the knitted
Mikrofaser-Garne eine hohe Wasseraufnahme-Kapazität (z.B. in % gegenüber dem Trockengewicht des Tuches) vorliegen kann. Gemäß einer Ausführungsform der Erfindung weist das Reinigungstuch hydrophobe Materialien in Kombination mit hydrophilen Materialien (PVF- Mikroschaum) auf und ist somit insgesamt amphiphil. Ein derartiges Microfibre yarns may have a high water absorption capacity (e.g., in% relative to the dry weight of the fabric). According to one embodiment of the invention, the cleaning cloth has hydrophobic materials in combination with hydrophilic materials (PVF microfoam) and is thus overall amphiphilic. Such a thing
Reinigungstuch weist eine hohe Reinigungswirkung sowohl für oleophilen als auch für hydrophilen Schmutz auf, was es für vielfältige Anwendungszwecke qualifiziert. Cleaning cloth has a high cleaning effect for both oleophilic and hydrophilic dirt, which makes it suitable for a variety of applications.
Vorteilhaft am Einsatz von PVF ist ferner, dass es aufgrund der freien OH- Gruppen an sich besonders saugfähig ist. Die Hydrophilie des PVF-Materials wird ferner dadurch gesteigert, dass es in Form eines Mikroschaums eingesetzt wird. Dieses Material weist aufgrund der Feinporig igkeit der An advantage of the use of PVF is further that it is particularly absorbent due to the free OH groups per se. The hydrophilicity of the PVF material is further enhanced by being used in the form of a microfoam. This material has due to the Feinporig igkeit the
Mikroschaumstruktur eine noch höhere Hydrophilie auf. Zusätzlich kann der PVF-Mikroschaum die Fasern und gegebenenfalls Garne des textilen  Microfoam structure on an even higher hydrophilicity. In addition, the PVF microfoam may be the fibers and optionally yarns of the textile
Trägermaterials weitgehend oder sogar vollständig umhüllen wodurch eine stabile mechanische Verbindung zwischen Trägermaterial und Envelope largely or even completely enveloping whereby a stable mechanical connection between the substrate and
Beschichtung/Imprägnierung erreicht werden kann. Das ist insbesondere dann vorteilhaft, wenn als Trägermaterial hydrophobe Materialien eingesetzt werden, da der PVF-Mikroschaum an derartigen Materialien eigentlich keine gute Anhaftung aufweist. Gemäß einer bevorzugten Ausführungsform der Erfindung wird ein Coating / impregnation can be achieved. This is particularly advantageous if hydrophobic materials are used as carrier material, since the PVF microfoam actually does not have good adhesion to such materials. According to a preferred embodiment of the invention is a
Trägermaterial aus Vliesstoff mit einem PVF-Mikroschaum kombiniert. Hierbei ist vorteilhaft, dass Vliesstoffe einfach und kostengünstig herstellbar sind und sich das Reinigungstuch dennoch durch eine hervorragende  Nonwoven backing material combined with a PVF microfoam. It is advantageous that nonwovens are simple and inexpensive to produce and the cleaning cloth yet by an excellent
Reinigungsleistung und Waschstabilität auszeichnet. Bei Verwendung eines Trägermaterials in Form eines Gewirkes oder Cleaning performance and wash stability distinguished. When using a carrier material in the form of a knitted fabric or
Gestrickes wird eine hohe Waschstabilität zusätzlich dadurch begünstigt, dass das gewirkte oder gestrickte Grundmaterial bereits in sich eine hohe Knitted, a high washing stability is further facilitated by the fact that the knitted or knitted base material already in itself a high
Waschstabilität aufweist, bedingt durch die räumliche Verkettung der Garne. Has washing stability, due to the spatial concatenation of the yarns.
Praktische Versuche haben ergeben, dass die Beschichtung und/oder Practical tests have shown that the coating and / or
Imprägnierung aus PVF vorteilhafterweise ein Flächengewicht von 10 bis 150 g/m2, vorzugsweise von 50 bis 100 g/m2, aufweist. Dabei weist das textile Trägermaterial vorteilhafterweise ein Flächengewicht von 80 bis 200 g/m2, vorzugsweise von 90 bis 80 g/m2, insbesondere von 100 bis 140 g/m2, auf. Impregnation of PVF advantageously has a basis weight of 10 to 150 g / m 2 , preferably from 50 to 100 g / m 2 . In this case, the textile substrate advantageously has a basis weight of 80 to 200 g / m 2 , preferably from 90 to 80 g / m 2 , in particular from 100 to 140 g / m 2 , on.
Als Basismaterial für das textile Trägermaterial können erfindungsgemäß Fasern aus einem hydrophoben Material eingesetzt werden. Der Begriff „hydrophob" wird erfindungsgemäß im herkömmlichen Sinne verstanden. As the base material for the textile carrier material fibers of a hydrophobic material can be used according to the invention. The term "hydrophobic" is understood according to the invention in the conventional sense.
Insbesondere werden im Sinne der Erfindung Materialien als hydrophob angesehen, bei denen Wasser auf der Oberfläche eines aus ihnen geformten kompakten Körpers einen Kontaktwinkel von größer oder gleich 90° aufweist. Der Kontaktwinkel kann bekanntermaßen z.B. mit einem Randwinkelmessgerät der Firma Krüss bestimmt werden. Als ebenfalls geeignet haben sich jedoch auch Fasern aus einem hydrophilen Material erwiesen. In particular, for the purposes of the invention, materials are considered to be hydrophobic, in which water has a contact angle of greater than or equal to 90 ° on the surface of a compact body formed from them. The contact angle may be known e.g. be determined with a contact angle measuring device from Krüss. However, fibers made of a hydrophilic material have also proven to be suitable.
Als besonders geeignet haben sich Fasern erwiesen, die folgende Materialien enthalten oder die aus den folgenden Materialien bestehen: Polyamid oder Polyester, Viskose, hydrophobierte Viskose, hydrophilierte Viskose, modifizierte Polyester, Polyacrylnitril, Triacetat, Acetat, Polyolefine wie beispielsweise Polyethylen und Polypropylen, Polyvinylchlorid und/oder Gemische hiervon. Erfindungsgemäß besonders bevorzugt ist der Einsatz von Polyamid, insbesondere Polyamid 6 oder 66, Polyethylen und/oder Polyester, Fibers made of the following materials have proven to be particularly suitable: polyamide or polyester, viscose, hydrophobized viscose, hydrophilized viscose, modified polyester, polyacrylonitrile, triacetate, acetate, polyolefins such as polyethylene and polypropylene, polyvinyl chloride and / or mixtures thereof. Particularly preferred according to the invention is the use of polyamide, in particular polyamide 6 or 66, polyethylene and / or polyester,
insbesondere PET und/oder Gemische hiervon. Als erfindungsgemäß besonders geeignet haben sich Fasern aus Polyester, Viskose, Polyethylen und insbesondere Gemischen hiervon erwiesen. in particular PET and / or mixtures thereof. Fibers made of polyester, viscose, polyethylene and in particular mixtures thereof have proved to be particularly suitable according to the invention.
Bevorzugt werden Stapelfasern und/oder Endlosfilamente. Gemäß einer bevorzugten Ausführungsform enthält ein derartiges textiles Trägermaterial Polyester, insbesondere PET und/ oder modifiziertes Polyester. Dieser kann entweder als ausschließlicher Rohstoff eingesetzt oder mit anderen Fasern (z.B. Viskose) gemischt werden. Der eingesetzte Titer der Faser kann im Bereich zwischen 0,05 und 3 dtex liegen. Für manche Anwendungszwecke ist es zweckmäßig, wenn er im Preference is given to staple fibers and / or continuous filaments. According to a preferred embodiment, such a textile carrier material contains polyester, in particular PET and / or modified polyester. This can be used either as an exclusive raw material or blended with other fibers (e.g., viscose). The used fiber titer can range between 0.05 and 3 dtex. For some applications, it is useful when in the
Bereich einer Mikrofaser liegt, das heißt zwischen 0,1 und 1 dtex. Vorteilhaft an der Verwendung der Mikrofasern ist, dass sie gute Reinigungsergebnisse zeigen, sehr weich sind und somit eine angenehme Haptik bieten. Range of a microfiber, that is between 0.1 and 1 dtex. The advantage of using the microfibers is that they show good cleaning results, are very soft and thus provide a pleasant feel.
Beispielsweise können Mikrofasern mit einem Titer von 0,05 bis 1 ,0 dtex, insbesondere von 0,1 - 0,7 dtex eingesetzt werden. For example, microfibers with a titre of 0.05 to 1.0 dtex, in particular 0.1 to 0.7 dtex, can be used.
Bei der Verteilung der Anteile des textilen Trägermaterials und der In the distribution of the proportions of the textile carrier material and the
Beschichtung/Imprägnierung mit PVF hat sich gezeigt, dass durch Coating / impregnation with PVF has been shown to be through
entsprechende Wahl der Anteile von textilem Trägermaterial und PVF-appropriate choice of the proportions of textile carrier material and PVF
Mikroschaum Reinigungstücher erhalten werden können, bei denen der textile und weiche Griff des Trägermaterials erhalten bleibt obwohl der PVF- Mikroschaum grundsätzlich im trockenen Zustand an Weichheit verliert und. damit zu einem weitgehend biegeharten Reinigungstuch führt. Microfoam cleaning wipes can be obtained in which the textile and soft feel of the substrate is maintained although the PVF microfoam basically loses its softness in the dry state and. thus leading to a largely flexible cleaning cloth.
Vorzugsweise weist das Reinigungstuch ein Gesamt-Flächengewicht von 90 bis 350 g/m2, noch bevorzugter von 200 bis 300 g/m2 auf. Dabei kann das Preferably, the cleaning cloth has a total basis weight of from 90 to 350 g / m 2 , more preferably from 200 to 300 g / m 2 . It can do that
Reinigungstuch Fasern vorzugsweise in einer Menge von 60 bis 200 g/m2, noch bevorzugter von 100 bis 120 g/m2 enthalten. Die für die Herstellung des textilen Flächengebildes eingesetzten Fasern können preiswert in unterschiedlichsten Ausführungen und Farben zur Verfügung gestellt werden und die PVA- Beschichtung, bzw. Imprägnierung mit herkömmlichen Verfahren auf einfache Art und Weise aufgebracht werden. Erfindungsgemäß bevorzugt wird das Flächengebilde mit einer vollflächigen Beschichtung, bzw. Imprägnierung versehen. Vorteilhaft an dieser Cleaning cloth fibers preferably in an amount of 60 to 200 g / m 2 , more preferably from 100 to 120 g / m 2 included. The fibers used for the production of the textile fabric can be inexpensively in a wide variety of Finishes and colors are provided and the PVA coating, or impregnation can be applied in a simple manner by conventional methods. According to the invention, the fabric is preferably provided with a full-surface coating or impregnation. An advantage of this
Ausführungsform ist, dass die vollflächige Beschichtung, bzw. Imprägnierung das Flächengebilde verfestigt und somit seine Stabilität erhöht. Dazu kommt, dass aufgrund des hohen Anteils an hydrophilem PVF zum Einen das Embodiment is that the full-surface coating, or impregnation solidifies the sheet and thus increases its stability. In addition, due to the high proportion of hydrophilic PVF on the one hand the
Entfernen einer größeren Menge Flüssigkeit von einer zu reinigenden Remove a larger amount of liquid from one to clean
Oberfläche besonders gut bewerkstelligt werden kann. Zum Anderen wird dadurch ermöglicht, dass beim Wischvorgang nur ein dünner, gleichmäßiger Flüssigkeitsfilm auf der zu reinigenden Oberfläche zurück bleibt. Dies erlaubt insbesondere auf glänzenden Oberflächen eine streifenfreie Reinigung. Surface can be accomplished particularly well. On the other hand, this makes it possible that only a thin, uniform liquid film remains on the surface to be cleaned during the wiping process. This allows streak-free cleaning especially on glossy surfaces.
Als textiles Flächengebilde können grundsätzlich sowohl verfestigte als auch nicht verfestigte textile Grundmaterialien eingesetzt werden. Um ein In principle, both consolidated and unconsolidated textile base materials can be used as the textile fabric. To one
mechanisch stabiles Reinigungstuch zu erhalten ist es jedoch vorteilhaft, wenn das textile Trägermaterial zumindest teilweise mechanisch, thermisch und/oder chemisch verfestigt ist. Insbesondere bei Vliesen kann die Verfestigung der wirr oder teilausgerichtet angeordneten Fasern mechanisch durch Vernadelung und/oder thermisch und/oder chemisch erfolgen. However, to obtain mechanically stable cleaning cloth, it is advantageous if the textile substrate is at least partially mechanically, thermally and / or chemically solidified. Particularly in the case of nonwovens, the consolidation of the randomly arranged or partially aligned fibers can be effected mechanically by needling and / or thermally and / or chemically.
Zur Herstellung des Flächengebildes können Fasern und/oder Garne For the production of the fabric fibers and / or yarns
eingesetzt werden. Das Flächengebilde liegt vorzugsweise in Form eines Vliesstoffs, einer Wirkware, einer Strickware, eines Geleges, Gewebes, be used. The fabric is preferably in the form of a nonwoven fabric, a knitted fabric, a knitted fabric, a fabric, fabric,
Geflechts, einer Maschenware, eines Filzes, Vlieses, einer Tuftingware, eines Stoffs, Kombinationen dergleichen sowie anderer flächiger Strukturen vor. Erfindungsgemäß besonders bevorzugt ist der Einsatz von Vliesstoffen. Braid, a knitted fabric, a felt, fleece, a tufted fabric, a fabric, combinations of the like and other planar structures. Particularly preferred according to the invention is the use of nonwovens.
Vliesstoffe bieten den Vorteil, dass sie einfach und kostengünstig hergestellt werden können. Ebenso kann das Flächengewicht des Reinigungstuches je nach gewünschtem Anwendungszweck variieren. Als für die meisten Zwecke geeignet haben sich Flächengewichte von 90 bis 350 g/m2, vorzugsweise 180 bis 230 g/m2 erwiesen. Je nach Anwendungszweck kann das textile Trägermaterial pflegeleicht und/oder flammfest ausgerüstet sein. So können die Fasern aus Polymeren aufgebaut sein, die Additive, wie Farbpigmente, permanent wirkende Nonwovens offer the advantage that they can be produced easily and inexpensively. Likewise, the basis weight of the cleaning cloth can vary depending on the desired application. As suitable for most purposes have basis weights of 90 to 350 g / m 2 , preferably 180 to 230 g / m 2 proved. Depending on the application, the textile substrate can be easy to clean and / or flameproof. Thus, the fibers may be composed of polymers containing additives, such as color pigments, permanently acting
Antistatika, Fungizide, Bakterizide, Akarizide und/oder die hydrophilen oder hydrophoben Eigenschaften beeinflussende Zusätze in Mengen bis zu 10 Gew.%, enthalten. Antistatic agents, fungicides, bactericides, acaricides and / or the hydrophilic or hydrophobic properties affecting additives in amounts up to 10 wt.% Contained.
Das textile Trägermaterial kann ferner Fasern (Stapelfasern oder The textile substrate may further comprise fibers (staple fibers or
Endlosfilamente) enthalten, wobei diese Fasern bei der Herstellung z.B. durch Spinnfärben eingefärbt werden. Als ebenfalls geeignet haben sich Endlosfilamente), which fibers in the manufacture of e.g. be dyed by spin dyeing. As well have been suitable
nachträgliche Färbeprozesse an den losen Fasern (Ballen-Färbung) oder am fertigen Trägermaterial (Stückfärbung) erwiesen. subsequent dyeing processes on the loose fibers (bale staining) or on the finished carrier material (piece staining) proved.
Aufgrund der vorteilhaften Eigenschaften des textilen Flächengebildes empfiehlt sich dessen Einsatz als Reinigungstextilie. So können aus ihm beispielsweise Wisch- oder Scheuertücher gefertigt werden. Due to the advantageous properties of the textile fabric, its use as a cleaning textile is recommended. So it can be made of it, for example, wiping or cleaning cloths.
Gemäß einer Ausführungsform der Erfindung ist beispielsweise auf der mit dem PVF-Mikroschaum beschichteten, bzw. imprägnierten Seite des textilen According to one embodiment of the invention, for example, on the coated or impregnated with the PVF microfoam side of the textile
Flächengebildes ein Druckmuster aus Scheuermittel, beispielsweise Sheet a print pattern of abrasives, for example
polierenden Partikeln, aufgebracht. Die polierenden Partikel könnten beispielsweise durch Kieselerde gebildet sein. Durch diese Partikel ergibt sich ein Reinigungstuch mit einer leicht abrasiven Wirkung. Das Scheuermittel kann in einem einfachen Druckverfahren in vielfältigsten Varianten auf das textile Trägermaterial aufgebracht werden. Somit kann ein zusätzlicher polishing particles, applied. The polishing particles could be formed for example by silica. These particles result in a cleaning cloth with a slightly abrasive effect. The abrasive can be applied in a simple printing process in a variety of variants on the textile substrate. Thus, an additional
Reinigungseffekt sowie eine dekorative Wirkung für die textile Struktur erzielt werden. Cleaning effect and a decorative effect for the textile structure can be achieved.
Für manche Anwendungszwecke kann es zweckmäßig sein, wenn das For some applications, it may be appropriate if the
Reinigungstuch gerauht, geschmirgelt, gebürstet oder kalandriert ist. Cleaning cloth roughened, sanded, brushed or calendered.
Es ist ebenfalls denkbar, das textile Trägermaterial vorzubehandeln. Dabei kommt z.B. eine Bedruckung, Kalandrierung oder partielle Prägung in Frage. Bei Verwendung eines farblosen PVF-Mikroschaums kann insbesondere die Bedruckung auch nach der BeSchichtung, bzw. Imprägnierung noch dauerhaft und waschstabil sichtbar bleiben. It is also conceivable to pretreat the textile substrate. In this case, e.g. a printing, calendering or partial embossing in question. When using a colorless PVF microfoam in particular the printing can remain visible even after the coating or impregnation still durable and wash stable.
Für die professionelle Reinigung ist es von Vorteil das Reinigungstuch in verschiedenen Farben auszugestalten, um so die Verwendung eines Tuches in nur einem Reinigungsbereich (z.B. Sanitärbereich) zu markieren. In der vorliegenden Erfindung kann die Einfärbung des Tuches beispielsweise auf die folgenden Weisen erfolgen: For professional cleaning, it is advantageous to design the cleaning cloth in different colors so as to mark the use of a cloth in only one cleaning area (e.g., sanitary area). In the present invention, the dyeing of the cloth can be done, for example, in the following ways:
Das textile Trägermaterial wird bereits partiell oder vollflächig gefärbt eingesetzt. In Kombination mit einem farblosen PVF Auftrag bleibt die The textile substrate is already used partially or fully colored. In combination with a colorless PVF order remains the
Grundfarbe des Trägermaterials noch sichtbar. Base color of the substrate still visible.
Alternativ dazu kann auch die zur Herstellung des PVF-Mikroschaums eingesetzte PVA-Lösung mit einem Farbpigment vermischt werden. In diesem Falle kann ein farbloses, und damit kostengünstigeres Trägermaterial gewählt werden und die Farbgebung des Reinigungstuches kann ganz weggelassen werden oder aber erst im späteren Schritt der PVF-Beschichtung, bzw. Alternatively, the PVA solution used to make the PVF microfoam may also be mixed with a colored pigment. In this case, a colorless, and thus cheaper carrier material can be selected and the color of the cleaning cloth can be omitted entirely or only in the later step of the PVF coating, or
-Imprägnierung gewählt und eingestellt werden. Dies hat insbesondere logistische Vorteile. Auch hier kann der Farbstoff so gewählt werden, dass er dauerhaft waschstabil und insbesondere ohne Ausbluten in das PVF Material eingebracht werden kann. Impregnation can be selected and adjusted. This has particular logistic advantages. Again, the dye can be chosen so that it can be permanently wash stable and in particular without bleeding introduced into the PVF material.
Ein weiterer Gegenstand der vorliegenden Erfindung umfasst ein Verfahren zur Herstellung des erfindungsgemäßen Reinigungstuches umfassend folgende Schritte: A further subject of the present invention comprises a process for producing the cleaning cloth according to the invention, comprising the following steps:
Zunächst wird ein textiles Flächengebilde, das kein PVA oder PVA in einer Menge von weniger als 50 Gew.% aufweist als textiles Grundmaterial hergestellt oder zur Verfügung gestellt. Dieses wird anschließend mit einer PVA-haltigen wässrige Lösung mit gängigen Aufbringungsmethoden, beispielsweise dem Foulardverfahren, einem Rakelverfahren, einem First, a fabric having no PVA or PVA in an amount of less than 50% by weight is prepared or provided as a base fabric. This is then mixed with a PVA-containing aqueous solution by conventional application methods, for example the padding method, a doctor blade method, a
Sprühauftrag, einem Pflatschwerk, mit einer Schlitzdüse oder einer Spray application, a Pflatschwerk, with a slot or a nozzle
Breitschlitzdüse auf das textile Grundmaterial versehen. Als besonders geeignet hat sich erwiesen das textile Grundmaterial mit einer wässrigen PVA-Lösung zu imprägnieren. Überschüssiges PVA kann je nach erwünschter Beschichtungs-, bzw. Imprägnierungsdicke abgequetscht, abgerakelt, abgesaugt oder auf andere Weise abgetragen werden. Das so behandelte Grundmaterial kann in eine wässrige Salzlösung und/oder - Suspension, beispielsweise eine Natriumsulfatlösung, und anschließend in eine saure Formaldehydlösung eingebracht werden. In der wässrigen Salzlösung wird der PVA-Lösung das Wasser entzogen, das PVA koaguliert. In der sauren Formaldehydlösung wird das PVA zu PVF vernetzt. Gemäß einer vorteilhaften Ausführungsform enthält die wässrige PVA-Lösung und/oder -Suspension noch weitere Zugabestoffe, wie z.B. Farbpigmente oder sonstige Additive oder Partikel, wie das o.g. Scheuermittel. Die PVA-Lösung enthält vorzugsweise einen Feststoffanteil an PVA zwischen 1 und 10 Gew.%, bevorzugt zwischen 3 und 7 Gew.%. Slot die provided on the textile base material. It has proven particularly suitable to impregnate the textile base material with an aqueous PVA solution. Excess PVA can be squeezed, doctored off, sucked off or otherwise removed depending on the desired coating thickness or impregnation thickness. The base material thus treated can be introduced into an aqueous salt solution and / or suspension, for example a sodium sulphate solution, and subsequently into an acidic formaldehyde solution. In the aqueous salt solution, the PVA solution is deprived of water and the PVA is coagulated. In the acidic formaldehyde solution, the PVA is cross-linked to PVF. According to an advantageous embodiment, the aqueous PVA solution and / or suspension contains further addition substances, such as color pigments or other additives or particles, such as the abovementioned abrasive. The PVA solution preferably contains a solids content of PVA between 1 and 10% by weight, preferably between 3 and 7% by weight.
Mit dem erfindungsgemäßen Verfahren kann auf einfache und hochproduktive Weise eine textile Struktur gefertigt werden, welche eine PVF-haltige Beschichtung, bzw. Imprägnierung aufweist. Die PVF-haltige Beschichtung, bzw. Imprägnierung kann in das textile Grundmaterial eindringen, wodurch sie fest in das textile Grundmaterial verankert wird. With the method according to the invention, a textile structure can be produced in a simple and highly productive manner, which has a PVF-containing coating or impregnation. The PVF-containing coating or impregnation can penetrate into the textile base material, whereby it is firmly anchored in the textile base material.
