Abstract

A reusable cleaning cloth for damp and dry cleaning of surfaces. The cloth is made of a textile base layer of non-woven fibers and, on the surface that provides the cleaning action, a plurality of filament loops which project out of this surface. The filament loops are concentrated in spaced apart surface regions separate from one another, like islands, by non-linear border lines delineating channels that are essentially free of filament loops. In its finished form, the island-like areas with the filament loops project 0.5 to 5 mm out of the base surface. The islands are aligned to be equidirectionally staggered relative to one another, each having a length of 4 to 50 mm with a corresponding width of 2 to 10 mm. The channels which separate the islands are as broad as one to two of these islands in the region between the adjacent long sides of the islands and narrow in the region of the adjacent ends of the islands.

Description

Die Erfindung betrifft ein wiederverwendbares Wischtuch zur Feucht- und Trockenreinigung von Flächen und trägt die im Oberbegriff des ersten Patentanspruchs aufgeführten Merkmale.The invention relates to a reusable wipe for wet and dry cleaning of surfaces and has the features listed in the preamble of the first claim.

Ein solches Wischtuch ist in WO 90/14039 beschrieben: Eine textile Grundlage aus nicht gewebten Fasern enthält auf ihrer zur Reinigung vorgesehenen Fläche eine Vielzahl von aus dieser Fläche hervortretenden Fadenschlaufen, welche durch Nadeln der textilen Grundlage erhalten worden und zu alternierend verlaufenden Flächenbereichen zusammengefaßt sind. Zwischen diesen Flächenbereichen liegen Trennlinien, welche über das gesamte Tuch verlaufen und in Form von Vertiefungen ausgestaltet sind. Diese Linien sind im wesentlichen frei von hervorstehenden Fadenschlaufen und werden durch das Faden- bzw. Fasermaterial der textilen Grundlage gebildet.Such a wiping cloth is described in WO 90/14039: A textile base made of non-woven fibers contains on its surface intended for cleaning a large number of thread loops protruding from this surface, which are obtained by needling the textile base and are combined into alternating surface areas. Between these surface areas there are dividing lines which run over the entire cloth and are designed in the form of depressions. These lines are essentially free of protruding thread loops and are formed by the thread or fiber material of the textile base.

Die tiefliegenden Linien verlaufen nicht gerade, sondern in gekrümmter bis geknickter Form, wodurch nicht allein eine besonders gute Gleitfähigkeit des Tuches auf der zu reinigenden Oberfläche erzielt wird, sondern auch beim Wischen Schmutz-Agglomerate sofort aufgenommen werden: Da die Übergänge zwischen den Schlaufenbereichen und den diese voneinander trennenden, durchgehenden Linien über ihren Verlauf ständig ihre Richtung ändern, wirkt nicht nur ein vertikal zur Wischrichtung gerichteter Druck auf die Schmutzpartikeln, sondern es entsteht zusätzlich eine schräg wischende Krafteinwirkung, welche den aufgenommenen Schmutz veranlaßt, sich entlang der Kanäle zu bewegen. Dies verringert die Gefahr, daß festsitzende Schmutzpartikel sich aus den mit Schlaufen versehenen Bereich wieder herauslösen.The deep lines do not run straight, but in a curved to kinked shape, which not only ensures that the cloth glides particularly well on the surface to be cleaned, but also that dirt agglomerates are immediately absorbed when wiping: because the transitions between the loop areas and the these continuous lines, which separate from one another, constantly change their direction over their course, not only does pressure act vertically on the wiping direction on the dirt particles, but there is also an oblique wiping force effect, which causes the dirt picked up to move along the channels. This reduces the risk of stuck dirt particles coming out of the looped area.

Mindestens eine der Schlaufen aufweisenden Flächen muß sich kontinuierlich von einem Ende des Tuches zum anderen erstrecken; bevorzugt verlaufen jedoch alle mit Fadenschlaufen versehenen Flächen und alle von Schlaufen freien, vertiefte Kanäle durchgehend in Längsrichtung des Tuches.At least one of the surfaces having loops must extend continuously from one end of the cloth to the other; however, preferably all surfaces provided with thread loops and all recessed channels free of loops run continuously in the longitudinal direction of the cloth.

Die Fadenschlaufen-Flächen und die Linien dazwischen können aus gleichem oder verschiedenem textilem Material bestehen, wie aus natürlichen, regenerierten und synthetischen Fasern, welche antistatisch, antistatisch ausgerüstet oder mit die Reinigung fördernden Substanzen behandelt sein können.The thread loop surfaces and the lines between them can consist of the same or different textile material, such as natural, regenerated and synthetic fibers, which can be antistatically, antistatically treated or treated with substances that promote cleaning.

Zur Herstellung eignen sich zahlreiche Verfahren, wobei einer Vorgehensweise analog der Herstellung eines Frotté-Tuches der Vorzug gegeben wird. Dabei geht man von einer gewebten Grundfläche aus.Numerous processes are suitable for the production, preference being given to a procedure analogous to the production of a terry cloth. This is based on a woven base.

Die hervorstehenden Schlaufen gemäß der Lehre in WO 90/14039 können auch abgeschnitten sein, so daß die Faserbüschel mit ihren Enden aus den erhabenen Flächen herausragen. In jedem Falle liegen langgestreckte, zumindest teilweise über das gesamte Wischtuch sich kontinuierlich erstreckende Flächenbereiche vor.The protruding loops according to the teaching in WO 90/14039 can also be cut off so that the ends of the fiber tufts protrude from the raised surfaces. In any case, there are elongated surface areas that extend at least partially over the entire wipe.

Die Aufgabe der vorliegenden Erfindung ist, ausgehend von einem Wischtuch der eingangs genannten Art, die weitere Verbesserung der Reinigungswirkung auch gegenüber unterschiedlich stark verschmutzten Flächenbereichen, unter Beibehaltung der leichten Gleitfähigkeit des Tuches und unter Ausnutzung der an sich bekannten Transport- und Schmutzhalte-Eigenschaften, wie sie durch die gekrümmten, von Fadenschlaufen freien Linien erzielt werden. Insbesondere ist es die Aufgabe der Erfindung, die auf die Schmutzpartikel vertikal und lateral einwirkenden Kräfte beim Wischen pro Flächeneinheit zu vermehren.The object of the present invention is, starting from a wipe of the type mentioned, the further improvement of the cleaning effect even against differently soiled areas, while maintaining the easy lubricity of the cloth and using the known transport and dirt-holding properties, such as they are achieved by the curved lines free of thread loops. In particular, it is the object of the invention to increase the forces acting vertically and laterally on the dirt particles when wiping per unit area.

Die Lösung der Aufgabe besteht in einem Wischtuch mit den Kennzeichen des ersten Patentanspruchs. Vorteilhafte Ausgestaltungen gehen aus den Kennzeichen der Unteransprüche hervor.The solution to the problem consists in a wipe with the characteristics of the first claim. Advantageous configurations emerge from the characteristics of the subclaims.

Der Begriff "Fadenschlaufen" bzw. "Schlaufen" soll auch in diesem Falle so verstanden werden, daß die Alternative abgeschnittener Schlaufen, also hervorstehender Faserbüschel-Enden statt gekrümmter, durchgehender Fasern, mit enthalten ist.The term "thread loops" or "loops" should also be understood in this case to include the alternative of cut loops, that is, protruding tufts of fibers instead of curved, continuous fibers.

Zur näheren Beschreibung des Wischtuchs sei die beispielhaft anzusehende Figur herangezogen:
Kennzeichen der Erfindung ist, daß die die Fadenschlaufen aufweisenden Flächen 2 jeweils isotrop zueinander ausgerichtet sind, wobei sie aus der textilen Grundlage 1, im Neuzustand des Tuches, in einem Ausmaß von 0,5 bis 5 mm herausragen. Es liegen dabei im gleichen Abstand voneinander, zueinander in ihrer Längsrichtung gestaffelt, d.h. versetzt angeordnete, individuelle Inseln 2 vor.For a more detailed description of the wipe, the figure to be viewed as an example is used:
Characteristic of the invention is that the surfaces 2 having the thread loops are each isotropically aligned with each other, whereby they protrude from the textile base 1, when the cloth is new, to an extent of 0.5 to 5 mm. There are the same distance from each other, staggered in their longitudinal direction, ie staggered, individual islands 2.

Die Inseln 2, welche aus einer Vielzahl von Fadenschlaufen aus Filamenten gebildet werden, besitzen jeweils eine Länge von 4 bis 50 mm bei einer entsprechenden Breite von 2 bis 10 mm, wobei der Längenwert zweckmäßig mindestens das Doppelte des Breitenwertes ausmacht.The islands 2, which are formed from a plurality of filament loops, each have a length of 4 to 50 mm with a corresponding width of 2 to 10 mm, the length value expediently making up at least twice the width value.

Die Anordnung "auf Lücke" bewirkt, daß versetzt, beiderseits jeden schmalen Endes einer durch die Fadenschlaufen gebildeten Fläche, je eine weitere inselartige Fläche 2 beginnt. Jedes dieser Enden ist beiderseits durch eine schlaufenfreie, bezüglich der Fläche 2 tiefer liegende Fläche 4 von dem Beginn/Ende der benachbarten, versetzt angeordneten Fläche 2 getrennt.The arrangement "on gap" has the effect that a further island-like surface 2 begins on both sides of each narrow end of a surface formed by the thread loops. Each of these ends is separated from the start / end of the adjacent, offset surface 2 on both sides by a loop-free surface 4 which is lower with respect to surface 2.

Mit dieser Ausgestaltung erstrecken sich die von hervorstehenden Schlaufen freien, tiefliegenden, ihren Verlauf periodisch ändernden Linien, welche durch die textile Grundlage 1 gebildet werden, kontinuierlich über die gesamte Wischfläche, wobei sie jeweils zwischen zwei benachbarten Längsseiten der inselartigen Schlaufenflächen 2, im Bereich 3, eine Breite gleich bis zweifach derjenigen einer dieser Flächen 2 einnehmen, hingegen jeweils im Bereich 4 der einander benachbarten Enden der zueinander gestaffelt bzw. versetzt positionierten, inselartig hervorstehenden Flächen 2 ihre Breite um etwa 1/2 bis 1/4 des ursprünglichen Betrages verringern.Dabei vereinigen sie sich dort in ihrem Verlauf zu der erwähnten tiefer liegenden Fläche 4.With this configuration, the low-lying, free-standing, periodically changing lines, which are formed by the textile base 1, extend continuously over the entire wiping surface, each between two adjacent longitudinal sides of the island-like loop surfaces 2, in the area 3, occupy a width equal to or twice that of one of these surfaces 2, but in each case in region 4 of the mutually adjacent ends of the staggered or staggered, island-like protruding surfaces 2 reduce their width by about 1/2 to 1/4 of the original amount, where they merge in their course to form the lower-lying surface 4 mentioned.

Die erfindungsgemäße Ausgestaltung der wischenden Oberfläche des Tuches erzielt sowohl im nassen wie im trockenen Zustand eine noch vollständigere Reinigungswirkung auch bezüglich festanhaftenden Schmutzes, verglichen mit dem genannten Stand der Technik. So ist bereits durch einmaliges Wischen ein Reinigungseffekt erzielbar, welcher mit einem Tuch gemäß WO 90/14039 erst durch mehrmaliges oder kreisendes Wischen erreicht werden kann.The configuration according to the invention of the wiping surface of the cloth achieves an even more complete cleaning effect both in the wet and in the dry state, also with regard to firmly adhering dirt, compared with the prior art mentioned. A cleaning effect can be achieved by wiping once, which can only be achieved with a cloth according to WO 90/14039 by wiping repeatedly or in a circular fashion.

Diese signifikante Verbesserung der Reinigungswirkung war nicht vorhersehbar und resultiert offenbar daraus, daß die Ausgestaltung der Schlaufen tragenden, herausragenden Flächen 2 als isolierte, gestaffelte, in jedem Gebrauchszustand aus der Wischfläche des Tuches herausragende Inseln insgesamt eine größere Kantenlänge eben dieser Inseln bei der Reinigung dem Schmutz entgegensetzt; die Summe aus lateraler und vertikaler Druckbeaufschlagung über diese Flächenkanten ist größer.This significant improvement in the cleaning effect was not predictable and apparently results from the fact that the design of the loop-bearing, protruding surfaces 2 as insulated, staggered islands protruding from the wiping surface of the cloth in every condition of use has a larger edge length overall for these islands when cleaning the dirt opposed; the sum of lateral and vertical pressurization over these surface edges is larger.

Durch den erfindungsgemäß ausgestalteten Verlauf sich verengender und erweiternder, tiefliegender Streifen und Kanäle sowie durch die Tatsache, daß diese Kanäle sich im Flächenbereich 4 der gestaffelt zueinander liegenden Enden/Anfänge der Inseln 2 deutlich verjüngen und vereinigen, werden die Schmutzpartikel nicht nur entlang der Kanäle transportiert und bei Kontakt mit den Faserschlaufen fest in diesen gehalten, sondern es ist zudem unmöglich geworden, daß dieser Transport über längere Strecken erfolgt, ohne daß sich die Partikel mit benachbarten Faserschlaufen verhaken. Diese Partikel können lediglich über die breiten Bereiche 3 zwischen den Längsseiten benachbarter inselartiger Schlaufenbereiche bewegt werden. Bei wischender Richtung in der Längsachse der tiefliegenden Kanäle stoßen sie jedoch spätestens in der Zone der Streifenverengung 4, d.h. im Bereich benachbarter Inselspitzen, zwangsläufig auf Faserschlaufen, in welchen sie dann festgehalten werden.Due to the course of narrowing and widening, deep-lying strips and channels designed according to the invention and the fact that these channels significantly taper and unite in the area 4 of the staggered ends / beginnings of the islands 2, the dirt particles are not only transported along the channels and held firmly in contact with the fiber loops, but it has also become impossible for this transport to take place over long distances without the particles getting caught with neighboring fiber loops. These particles can only be moved over the wide areas 3 between the long sides of adjacent island-like loop areas. With a wiping direction in the longitudinal axis of the deep-lying channels, however, they meet in the zone at the latest the narrowing of the strip 4, ie in the region of neighboring island tips, inevitably on fiber loops in which they are then held.

Trotz der isotropen Ausrichtung der Wischfläche ist somit Gewähr gegeben, daß auch beim Abweichen von der bevorzugten Wischrichtung senkrecht zu den Inselschlaufen-Kanten, d.h. zum wesentlichen Verlauf der tiefliegenden Linien, bis hin zum im wesentlichen parallelen Wischen, ein längerer als einen Wischzug dauernder Transport von Schmutzpartikeln ohne Kontakt mit den Faserschlaufen nicht möglich ist.Despite the isotropic alignment of the wiping surface, there is therefore a guarantee that even if the preferred wiping direction deviates, it is perpendicular to the island loop edges, i.e. for the essential course of the deep-lying lines, up to the essentially parallel wiping, it is not possible to transport dirt particles longer than a wiping stroke without contact with the fiber loops.

Die Herstellung der Faserschlaufen ist auf verschiedene Art und Weise möglich, wobei von der bereits erwähnten Frottébildungs-Technik aus einem Gewebe ausgegangen werden kann. Alternativen sind, wie z.B. in der Druckschrift GB 2 162 213 A aufgeführt, das Nadeln eines nichtgewebten Faservliestoffs, wobei Fasern oder Filamente aus der Gegenfläche des Tuches durch dieses hindurch auf die Wischfläche in Schlaufenform mittels Widerhaken herausgezogen werden; die Faserschlaufen bestehen also aus Material der gegenüberliegenden Fläche. Auch ist es möglich, bereits von der gegenüberliegenden Fläche mit konkav gekrümmten Nadelenden durch das Basisvlies hindurchzustoßen.The manufacture of the fiber loops is possible in different ways, it being possible to start from a woven fabric using the terry formation technique already mentioned. Alternatives are, e.g. in GB 2 162 213 A, the needling of a non-woven nonwoven fabric, fibers or filaments being pulled out of the mating surface of the cloth through it onto the wiping surface in a loop shape by barbs; the fiber loops are made of material from the opposite surface. It is also possible to push through the base fleece from the opposite surface with concave curved needle ends.

In einem ähnlichen, ebenfalls bekannten Verfahren bedient man sich sogenannter Strukturnadelmaschinen, wie sie z.B. von der Firma Dilo hergestellt und vertrieben werden. Hierbei ist die Menge der hervorstehenden Faserschlaufen durch die Wahl der Nadeltypen und der Hubzahl der Nadeln, die Höhe der vorstehenden Faserschlaufen durch die Einstichtiefe der Nadeln in weiten Bereichen jeweils regulierbar. Die Handhabung solcher Strukturnadelmaschinen ist dem Fachmann geläufig.In a similar, also known method, so-called structural needle machines are used, such as those e.g. manufactured and distributed by Dilo. The amount of the protruding fiber loops can be regulated in a wide range by the choice of needle types and the number of strokes of the needles, and the height of the protruding fiber loops by the penetration depth of the needles. The skilled worker is familiar with the handling of such structural needle machines.

Die für das Wischtuch erfindungsgemäß erforderliche Grobstrukturierung in schlaufentragende Inselbereiche 2 und dazwischenliegende Vertiefungen ohne hervorstehende Schlaufen erfolgt durch die Wahl der Anordnung der Nadeln auf dem Nadelbrett entsprechend der gewünschten Anordnung der Schlaufen tragenden Bereiche 2 am fertigen Wischtuch.The rough structuring required according to the invention for the wiping cloth into loop-carrying island regions 2 and intervening depressions without protruding loops takes place through the choice of the arrangement of the needles on the needle board according to the desired arrangement of the loop-carrying areas 2 on the finished wipe.

In einer bevorzugten Ausführungsform bestehen die textile Grundlage 1 zumindest teilweise aus Cellulosefasern und die schlaufentragenden, inselförmigen Bereiche 2 aus Synethesefilamenten, bevorzugt aus Polyester. Durch diese Materialwahl wird den Schmutzpartikeln ein besonders effektiver Widerstand beim Wischen entgegengesetzt.In a preferred embodiment, the textile base 1 consists at least partially of cellulose fibers and the loop-bearing, island-shaped regions 2 consist of synthetic filaments, preferably of polyester. This choice of material provides the dirt particles with a particularly effective resistance when wiping.

Selbstverständlich ist es jedoch auch möglich, für die herausragenden Bereiche 2 Cellulosefasern zu wählen, wenn auf der zum Wischen bestimmten Fläche der saugende Effekt dominieren soll. Entsprechend der Herstellungstechnik ist dann dafür Sorge zu tragen, daß vor dem Bilden der Schlaufen die nicht wischende Fläche des Tuches mehrheitlich die später die Schlaufen bildenden Fasern enthält.Of course, it is also possible to choose 2 cellulose fibers for the outstanding areas if the suction effect is to dominate on the surface intended for wiping. According to the manufacturing technique, care must then be taken to ensure that the majority of the non-wiping surface of the cloth contains the fibers that later form the loops before the loops are formed.

Bevorzugt bezüglich der Einfachheit und Kostengünstigkeit des Herstellungsverfahrens, bezüglich der guten Gebrauchseigenschaften und Robustheit des Tuches und bezüglich der Verfügbarkeit des Basismaterials 1 liegt das erfindungsgemäße Wischtuch in Form eines nicht gewebten Flächengebildes, also eines Vliesstoffs, vor.The wipe according to the invention is preferably in the form of a non-woven fabric, that is to say a nonwoven fabric, preferably with regard to the simplicity and cost-effectiveness of the production process, with regard to the good usage properties and robustness of the wipe and with regard to the availability of the base material 1.

In einer optisch prägnanten Variante sind dieinselartig hervortretenden Bereiche 2 bezüglich der dazwischenliegenden Linien verschieden gefärbt. Die technische Wirkung des Reinigens wird dadurch optisch deutlich gemacht, und durch die Konzentration unterschiedlich gefärbter Fasern auf der Rück- und Vorderseite des Tuches vor der Herstellung der Schlaufen ist ein solcher Effekt leicht erzielbar.In an optically striking variant, the areas 2 protruding like an island are colored differently with respect to the lines in between. The technical effect of cleaning is thereby made visually clear, and the concentration of differently colored fibers on the back and front of the cloth before the production of the loops makes it easy to achieve this effect.

Die Faserstärken können an den Verwendungszweck angepaßt werden; zum Reinigen robusterer Oberflächen sind Titer von 100 dtex die bevorzugte Wahl;The fiber strengths can be adapted to the intended use; titres of 100 dtex are the preferred choice for cleaning more robust surfaces;
