Abstract

A cleaning cloth is described which is made from microfibers having a nonporous fiber core surrounded by a foamed coating layer containing open celled pores. The microfibers may optionally be combined with other types of fibers. The cloth has a high capacity for holding dirt and in another application, a detergent, bacteriocide, fungicide or preservative can be contained in the pores to provide a combination cleaning cloth.

Description

Die Erfindung betrifft ein Reinigungstuch mit einem Gehalt an porösen Fasern.The invention relates to a cleaning cloth containing porous fibers.

Bestimmungsgemäß ist ein Reinigungstuch dafür vorgesehen, Schmutz von der Oberfläche eines zu reinigenden Gegenstandes abzulösen und im Inneren zu speichern. Die Speicherkapazität ist im wesentlichen von dem enthaltenen Porenvolumen abhängig, und man ist deshalb seit langem bemüht, dieses möglichst optimal zu gestalten. Eine in dieser Hinsicht seit langem genutzte Möglichkeit besteht wegen des Gehaltes an Hohlräumen in der Verwendung natürlich gewachsener Fasern. Diese sind jedoch relativ brüchig, und es kann deshalb schon nach kurzem Gebrauch zur Ablösung von Faserbestandteilen kommen, die sich in Gestalt von staubförmigen Partikeln oder Fusseln auf den zu reinigenden Flächen niederschlagen.A cleaning cloth is intended to remove dirt from the surface of an object to be cleaned and to store it inside. The storage capacity is essentially dependent on the pore volume contained, and efforts have therefore been made for a long time to make it as optimal as possible. One option that has long been used in this regard is the use of naturally grown fibers because of the void content. However, these are relatively fragile and, after a short use, fiber components can become detached, which are deposited in the form of dust-like particles or lint on the surfaces to be cleaned.

Der Erfindung liegt die Aufgabe zugrunde, ein Reinigungstuch zu entwickeln, das diesen Nachteil bei sonst guten Gebrauchseigenschaften nicht mehr aufweist.The invention has for its object to develop a cleaning cloth that no longer has this disadvantage with otherwise good properties.

Diese Aufgabe wird erfindungsgemäß durch ein Reinigungstuch der eingangs genannten Art gelöst, das dadurch gekennzeichnet ist, daß die porösen Fasern Mikrofasern aus einem polymeren Werkstoff sind, die einen im wesentlichen porenfreien Faserkern und einen offenporig geschäumten Fasermantel aufweisen, und wobei die Mikrofasern gegebenenfalls mit andersartigen Fasern vermischt und/oder abgedeckt und durch ein Bindemittel verklebt oder autogen verschweißt sind.This object is achieved according to the invention by a cleaning cloth of the type mentioned at the outset, which is characterized in that the porous fibers are microfibers made of a polymeric material which have a substantially pore-free fiber core and an open-pore foamed fiber jacket, and the microfibers optionally with different types of fibers are mixed and / or covered and glued by a binder or autogenously welded.

Die andersartigen Fasern können aus dem selben polymeren Werkstoff bestehen wie die Mikrofasern, was Vorteile in physiologischer Hinsicht und/oder in bezug auf die Beständigkeit gegenüber aggressiven Reinigungsflüssigkeiten bieten kann. Bei einer Ausführung, bei der die Mikrofasern und die andersartigen Fasern aus verschiedenen polymeren Werkstoffen bestehen, ergibt sich demgegenüber der Vorteil, die mechanischen Eigenschaften des Reinigungstuches in größerem Rahmen modifizieren zu können. Insbesondere läßt sich auf diese Weise der Wunsch nach einer guten Abriebbeständigkeit besser mit einer guten Flexibilität vereinen.The different types of fibers can consist of the same polymeric material as the microfibers, which can offer advantages in physiological terms and / or in terms of resistance to aggressive cleaning liquids. In contrast, in an embodiment in which the microfibers and the different types of fibers consist of different polymeric materials, there is the advantage of being able to modify the mechanical properties of the cleaning cloth on a larger scale. In particular, the desire for good abrasion resistance can be better combined with good flexibility in this way.

Als besonders vorteilhaft hat sich in diesem Zusammenhang die Verwendung einer Fasermischung erwiesen, bei der die Mikrofasern aus Polycarbonat bestehen und die andersartigen Fasern aus Polyamid, Polypropylen oder Zellwolle.In this context, it has proven particularly advantageous to use a fiber mixture in which the microfibers are made of polycarbonate and the other fibers are made of polyamide, polypropylene or wool.

Die Mikrofasern haben bevorzugt ein bandförmiges Profil, das demjenigen einer liegenden Acht vergleichbar ist. Das Verhältnis aus der größten Breite eines solchen Profils und der größten Dicke liegt im Bereich von 2,5 bis 5. Durch die überwiegend flachliegende Anordnung des Profils dieser Fasern innerhalb des Reinigungstuches ist ihre mechanische Widerstandsfähigkeit relativ groß, was sich positiv in bezug auf_die Beständigkeit gegen Abrieb auswirkt. Der größte Durchmesser-beträgt 1 bis 20 D.The microfibers preferably have a band-shaped profile that is comparable to that of a lying figure eight. The ratio of the greatest width of such a profile and the greatest thickness is in the range from 2.5 to 5. Due to the predominantly flat arrangement of the profile of these fibers within the cleaning cloth, their mechanical resistance is relatively large, which has a positive effect on the resistance to Abrasion affects. The largest diameter is 1 to 20 D.

Bevorzugt werden Mikrofasern verwendet, deren Molekularstruktur infolge einer vorausgegangenen Verstreckung zumindest eine teilweise Orientierung erfahren hat. Die Zugfestigkeit solcher Mikrofasern ist größer als diejenige einer vergleichbaren Mikrofaser mit einer orientierungslosen amorphen Molekularstruktur.Microfibers are preferably used, the molecular structure of which has undergone at least a partial orientation as a result of a previous stretching. The tensile strength of such microfibers is greater than that of a comparable microfiber with an orientationless amorphous molecular structure.

Als andersartige Fasern kommen bevorzugt synthetisch hergestellte Stapelfasern oder Endlosfasern zur Anwendung, vorzugsweise Kräuselfasern. Alle handelsüblichen Qualitäten sind geeignet, wobei es bevorzugt ist, solche auszuwählen, deren Durchmesser um das 5- bis 20-fache größer ist als der größte Durchmesser der Mikrofasern. Aus einer gleichmäßigen Vermischung beider Faserarten resultiert neben einer verbesserten Sprungelastizität eine vergrößerte Fülligkeit mit verbessertem Schmutzaufnahmevermögen. Optimale Eigenschaften werden durch die Einlagerung gekräuselter Stapelfasern erreicht.Other types of fibers are preferably synthetically produced staple fibers or continuous fibers, preferably crimped fibers. All commercially available qualities are suitable, although it is preferred to select those whose diameter is 5 to 20 times larger than the largest diameter of the microfibers. A uniform mixing of both types of fibers results in improved elasticity, increased filling and improved dirt absorption capacity. Optimal properties are achieved by embedding crimped staple fibers.

Die Stapelfasern oder Endlosfasern können aus einem polymeren Werkstoff bestehen, der einen niedrigeren Schmelzpunkt aufweist als derjenige der Mikrofasern: Eine entsprechende Ausführung läßt sich einfach herstellen und durch eine Punktschweißung verfestigen. Dabei wird das Reinigungstuch in voneinander getrennten Flächenbereichen zusammengepresst und auf eine Temperatur oberhalb des Erweichungspunktes der Stapelfasern oder Endlosfasern erwärmt. Deren Substanz verschmilzt vollständig zu fensterähnlich erscheinenden Flächen, in die die in ihrer Gestalt vollkommen unveränderten Mikrofasern eingebunden sind. Eine entsprechende Punktschweißung läßt sich im großtechnischen Maßstab unter Verwendung eines beheizten Kalanders realisieren, dessen Walzen eine entsprechende Oberflächengravierung aufweisen. Die einzelnen Schweißstellen können bei einem Flächengewicht des Reinigungstuches von 120 g/m2 einen Durchmesser von 0,3 mm und einen gegenseitigen Abstand von 1,2 bis 2,8 mm haben. Die Bindung kann aber auch mit Ultraschall oder Hochfrequenz erfolgen. In den Zwischenräumen zwischen den Schweißflächen liegen die Fasern ohne jede gegenseitige Bindung lose aufeinander auf. Sie sind in diesen Bereichen dementsprechend beweglich, und aufzunehmender Schmutz wird leicht in das Innere des Reinigungstuches hineintransportiert.The staple fibers or continuous fibers can consist of a polymeric material that has a lower melting point than that of the microfibers: a corresponding design can be produced easily and solidified by spot welding. The cleaning cloth is pressed together in separate surface areas and heated to a temperature above the softening point of the staple fibers or continuous fibers. Their substance melts completely into window-like surfaces, in which the microfibers, which are completely unchanged in shape, are integrated. A corresponding spot welding can be carried out on an industrial scale using a heated calender, the rollers of which have a corresponding surface engraving. The individual welds can have a diameter of 0.3 mm and a mutual distance of 1.2 to 2.8 mm with a basis weight of the cleaning cloth of 120 g / m 2 . The binding can also be done with ultrasound or high frequency. In the spaces between the welding surfaces, the fibers lie without any mutual Binding loosely on each other. Accordingly, they are movable in these areas, and dirt to be picked up is easily transported into the inside of the cleaning cloth.

Durch die Anordnung einer besonderen Schicht aus Stapel- oder Endlosfasern auf den Oberflächen des Reinigungstuches ergibt sich eine größere mechanische Widerstandsfähigkeit insbesondere gegenüber Abrieb. Es ist selbstverständlich, daß eine derartige Stapel- oder Endlosfaserabdeckschicht nur eine relativ geringe Dichte haben darf.The arrangement of a special layer of staple or continuous fibers on the surfaces of the cleaning cloth results in greater mechanical resistance, in particular to abrasion. It goes without saying that such a stacked or continuous fiber covering layer may only have a relatively low density.

Nach einer vorteilhaften Ausgestaltung ist es vorgesehen, daß in die Poren des offenporig geschäumten Fasermantels der Mikrofasern ein Detergens, ein Netzmittel, ein Bakterizid und/oder ein Fungizid und/ oder ein Konservierungsmittel eingelagert ist. Die Poren der Mikrofasern erstrecken sich im wesentlichen senkrecht zur Oberfläche, und sie haben eine überwiegend zylindrische Gestalt und gleichmäßige Verteilung. Sie sind, bedingt durch ihre geringe Größe, nicht kompressibel, und ein darin eingelagerter Wirkstoff läßt sich deshalb nicht durch einen mechanischen Vorgang aus den Poren entfernen, sondern lediglich durch die Einwirkung eines Lösungsmittels, beispielsweise von Wasser. Dieser Effekt wird erfindungsgemäß für eine wesentliche Erweiterung und Verbesserung der Gebrauchseigenschaften ausgenutzt, indem die Substanzen aus den vorstehend genannten Wirkstoffklassen in die Poren eingelagert werden. Die erzielte Wirkung ist in jedem Falle eine Langzeitwirkung. Sie ist u.a. auch durch den natürlichen Verschleiß begrenzt. Eine ähnlich gleichmäßige und sparsame Anwendung derartiger Wirkstoffe war unter den Gegebenheiten, die bei einem normalen Haushalt bestehen, bisher nicht möglich.According to an advantageous embodiment, it is provided that a detergent, a wetting agent, a bactericide and / or a fungicide and / or a preservative is embedded in the pores of the open-pore foamed fiber jacket of the microfibers. The pores of the microfibers extend essentially perpendicular to the surface, and they have a predominantly cylindrical shape and uniform distribution. Due to their small size, they are not compressible, and an active substance stored therein can therefore not be removed from the pores by a mechanical process, but only by the action of a solvent, for example water. According to the invention, this effect is used for a substantial expansion and improvement of the use properties, in that the substances from the above-mentioned classes of active substances are incorporated into the pores. The effect achieved is in any case a long-term effect. It is among others also limited by natural wear and tear. A similarly uniform and economical use of such active ingredients has not been possible under the conditions that exist in a normal household.

Die Poren haben einen Durchmesser von 0,01 bis 0,5 µ, vorzugsweise von 0,05 bis 0,2 P, und die Summe ihrer Querschnitte überdeckt 1 bis 95 %, vorzugsneise 10 bis 70 % der gesamten Oberfläche. Sie bilden zusammen eine regelrechte, klar von dem porenfreien Faserkern abgegrenzte, geschäumte Sicht, die 40 bis 80 %, vorzugsweise 60 %, des gesamten Querschnittes überdeckt. Das enthaltene Speichervolumen ist dementsprechend erheblich.The pores have a diameter of 0.01 to 0.5 μm, preferably 0.05 to 0.2 P , and the sum of their cross sections covers 1 to 95%, preferably 10 to 70% of the total surface. Together they form a regular, clearly defined, foamed view clearly defined by the non-porous fiber core, the 40 to 80%, preferably 60%, of the entire cross cut covered. The storage volume contained is accordingly considerable.

Die Vliesstruktur des vorgeschlagenen Reinigungstuches kann auch durch ein Bindemittel stabilisiert werden, welches durch Imprägnieren und/ oder Drucken ein- und/oder aufgebracht ist. Bevorzugt kommen Bindemittel zur Anwendung, die aus einem geschäumten Weichkunststoff bestehen, beispielsweise aus einem Polyurethan- oder einem Latexschaum. Sofern ein Druckverfahren angewendet wird, ergibt sich die Möglichkeit, das Bindemittel musterartig auf einer oder auf beiden Oberflächen zu verteilen. Im erstgenannten Falle ergibt sich der Vorteil, groben Schmutz zunächst mit der bedruckten Seite des Reinigungstuches ablösen zu können, der teilweise von den Zwischenräumen aufgenommen wird, das Tuch anschließend zu wenden und den Reinigungsvorgang durch Benutzung der unbedruckten Vorderseite des Reinigungstuches abzuschließen. Eine gute Wirksamkeit durch Anwendung der bedruckten Seite wird insbesondere dann erreicht, wenn das musterartig auf die Oberfläche des Reinigungstuches aufgedruckte Bindemittel die Oberfläche reliefartig überragt, wenn die einzelnen Bindemittelflächen scharfkantig begrenzt und nicht breiter als 2 bis 3 mm sind. Die gegenseitige Zuordnung kann beliebig sein. Das Verhältnis aus den gegenseitigen Abständen und der Breite der einzelnen Teilflächen soll jedoch nicht mehr als 5 betragen. Die Teilflächen können durch Großbuchstaben gebildet werden, die einander unter Einhaltung der gestellten Bedingung zugeordnet sind.The nonwoven structure of the proposed cleaning cloth can also be stabilized by a binder which is applied and / or applied by impregnation and / or printing. Binders are preferably used which consist of a foamed soft plastic, for example a polyurethane or a latex foam. If a printing process is used, there is the possibility of distributing the binder in a pattern on one or both surfaces. In the former case, there is the advantage of being able to first remove coarse dirt with the printed side of the cleaning cloth, which is partially taken up by the gaps, then turn the cloth over and complete the cleaning process by using the unprinted front of the cleaning cloth. A good effectiveness by using the printed side is achieved in particular if the binder printed in pattern on the surface of the cleaning cloth protrudes above the surface in relief, if the individual binder surfaces have sharp edges and are not wider than 2 to 3 mm. The mutual assignment can be arbitrary. However, the ratio of the mutual distances and the width of the individual partial areas should not be more than 5. The subareas can be formed by capital letters, which are assigned to each other in compliance with the given condition.

Eine beispielhafte Ausführung des erfindungsgemäßen Reinigungstuches ist in den in der Anlage beigefügten Aufnahmen wiedergegeben.

  • Abbildung 1 zeigt eine drapierfähige Ausführung des Reinigungstuches im Maßstab 1 : 4.
  • Abbildung 2 zeigt eine erfindungsgemäße Ausführung im Maßstab 1 : 20, bei der die punktverfestigte Oberfläche umgeben von den reinigungswirksamen Flächen aus Feinstfasern sichtbar wird.
  • Abbildung 3, Maßstab 1 : 20, nimmt Bezug auf ein Feinstfaservlies, welches beidseitig mit einem dünnen Vlies abgedeckt und durch eine Punktschweißung verfestigt ist. In die dabei gebildeten Schweißflächen sind die Fasern der dünnen Abdeckvliese eingebunden. Der Durchgriff der Feinstfaserlage durch die öffnungen zwischen den Fasern der Abdeckvliese ist deutlich zu erkennen.
An exemplary embodiment of the cleaning cloth according to the invention is reproduced in the photographs enclosed in the system.
  • Figure 1 shows a drapable version of the cleaning cloth on a scale of 1: 4.
  • Figure 2 shows an embodiment according to the invention on a scale of 1:20, in which the point-consolidated surface surrounded by the cleaning-effective surfaces made of fine fibers is visible.
  • Figure 3, scale 1:20, refers to a fine fiber fleece, which is covered on both sides with a thin fleece and is fixed by spot welding. The fibers of the thin cover fleeces are integrated into the welding surfaces formed. The penetration of the fine fiber layer through the openings between the fibers of the cover fleece can be clearly seen.
