Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Verwendung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a use according to the preamble of patent claim 1.

Stand der TechnikState of the art

Vliesstoffe mit antimikrobieller Ausrüstung sind aus der US 2004/0214485 A1 und der WO 2007/078203 A1 bekannt.Nonwovens with antimicrobial finish are from the US 2004/0214485 A1 and the WO 2007/078203 A1 known.

Aus dem Stand der Technik sind Vliesstoffe bekannt, weiche einen antimikrobiell wirkenden Dotierstoff aufweisen. Dabei wirkt ein antimikrobiell wirkender Stoff antibakteriell, antiviral, antimykotisch und/ oder gegen Sporen. Vor diesem Hintergrund hat sich insbesondere Silber als geeigneter antimikrobieller Stoff erwiesen.From the prior art nonwovens are known which have an antimicrobial dopant. In this case, an antimicrobial substance acts antibacterial, antiviral, antifungal and / or against spores. Against this background, silver in particular has proven to be a suitable antimicrobial agent.

Es ist bereits bekannt, Toilettenpapier mit Silber auszurüsten. Diese Ausrüstung ist jedoch nicht dauerhaft, da das Silber lediglich oberflächlich auf das Toilettenpapier aufgetragen wird.It is already known to equip toilet paper with silver. However, this equipment is not durable, as the silver is only superficially applied to the toilet paper.

Häufig wird Silber auch mittels Bindemitteln an textilen Stoffen festgelegt. Durch Waschprozesse wird das aufgetragene Silber jedoch abgelöst und kann in Wasseraufbereitungsanlagen eindringen. Dies ist ein äußerst nachteiliger Effekt, mit dem hohe wirtschaftliche Schäden verbunden sind.Frequently, silver is also determined by means of binders on textile materials. By washing processes, however, the applied silver is peeled off and can penetrate into water treatment plants. This is a very detrimental effect associated with high economic damage.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Wischtuch anzugeben, welches sich durch eine langfristig wirksame Reaktivität des antimikrobiell wirkenden Dotierstoffes auszeichnet und zugleich mehrfach kostengünstig waschbar ist.The invention is therefore based on the object to provide a wipe, which is characterized by a long-term effective reactivity of the antimicrobial dopant and at the same time is multi-cost washable.

Erfindungsgemäß wird die voranstehende Aufgabe mit den Merkmalen des Patentanspruchs 1 gelöst.According to the invention the above object is achieved with the features of claim 1.

Erfindungsgemäß ist zunächst erkannt worden, dass ein Vliesstoff, welcher Endlosfasem aufweist, auch nach mehreren Waschprozessen eine gute Qualität aufweist. Dies hängt damit zusammen, dass Endlosfasem an einer Vielzahl von Stellen miteinander verschlungen sind und sich daher nur schwer aus dem Vliesstoffverbund herauslösen können. Des Weiteren ist erkannt worden, dass die Verwendung von Bikomponentenfasern mit einem Faserkörper, in welchem zumindest ein Dotierstoff zur antimikrobiellen Ausrüstung aufgenommen ist, erlaubt, den Vliesstoff zu verfestigen. Dabei ist konkret denkbar den Vliesstoff durch einen Wasserstrahlvemadelungsprozess zu verfestigen. Dabei können die Bikomponentenfasern teilweise oder vollständig zu sehr feinen Elementarfasern aufgesplittet werden. Denkbar ist auch, den Vliesstoff durch eine thermische Behandlung zu verfestigen. Ganz konkret ist erkannt worden, dass die Einbindung des antimikrobiellen Dotierstoffes in den Faserkörper eine äußerst langfristige Abgabe des Dotierstoffes sicherstellt. Die antimikrobielle Wirkung wird auf das Wischtuch begrenzt, indem Keimwachstum im Wischtuch selbst weitgehend verhindert wird. Erfindungsgemäß wird der antimikrobiell wirksame Stoff gerade nicht in erheblichem Maße an Oberflächen abgegeben, die mit dem Wischtuch behandelt werden. Der Dotierstoff wird direkt in den Faserkörper eingebunden, wodurch vor allem an der Oberfläche der Endlosfasem eine antimikrobielle Wirkung entsteht. Die Freisetzung des Dotierstoffes erfolgt nur in sehr geringen Mengen, er bleibt weitestgehend im Vliesstoff bzw. im Faserkörper gebunden.According to the invention, it has first been recognized that a nonwoven fabric which has continuous fibers has a good quality even after several washing processes. This is due to the fact that Endlosfasem are entangled at a variety of locations with each other and therefore difficult to detach from the nonwoven composite. Furthermore, it has been recognized that the use of bicomponent fibers with a fibrous body in which at least one dopant is included for antimicrobial finishing allows the nonwoven to be consolidated. It is concretely conceivable to solidify the nonwoven fabric by a water jet needling process. The bicomponent fibers can be partially or completely split up into very fine elementary fibers. It is also conceivable to solidify the nonwoven fabric by a thermal treatment. All Specifically, it has been recognized that incorporation of the antimicrobial dopant into the fiber body ensures extremely long term delivery of the dopant. The antimicrobial effect is limited to the wipe by largely preventing germ growth in the wipe itself. According to the invention, the antimicrobial active substance is not released to a considerable extent on surfaces which are treated with the wipe. The dopant is incorporated directly into the fiber body, which creates an antimicrobial effect, especially on the surface of the endless fibers. The release of the dopant takes place only in very small amounts, it remains largely bound in the nonwoven fabric or in the fiber body.

Die erfindungsgemäße Verwendung zeigt überraschenderweise einen kombinatorischen Effekt, der sich einer hohen Reaktivität des Dotierstoffes und einer hohen Waschbeständigkeit des Wischtuches niederschlägt. Ein waschbares, dauerhaft antimikrobiell dotiertes Wischtuch lässt beispielsweise in milchkontaminiertem Zustand keine bakterielle Zersetzung zu, so dass nahezu keine Geruchsbelastung im Haushalt entstehen kann. Ganz besonders vorteilhaft ist jedoch die Benutzung in der gewerblichen Reinigung, da hier Wischtücher täglich gewaschen und getrocknet werden. Werden die Wischtücher erfindungsgemäß antimikrobiell ausgerüstet, so kann auf eine anschließende Trocknung der Wischtücher verzichtet werden. Versuche haben gezeigt, dass bei jeder Wäsche eine Energieeinsparung von mehr als 3 kWh/kg Wischtuch realisiert werden kann.The use according to the invention surprisingly shows a combinatorial effect, which is reflected in a high reactivity of the dopant and a high washing resistance of the wipe. A washable, permanently antimicrobially-doped wipe, for example, does not allow any bacterial decomposition in milk-contaminated state, so that almost no odor pollution in the household can arise. Very particularly advantageous, however, is the use in commercial cleaning, since wipers are washed and dried here daily. If the wipes according to the invention equipped antimicrobial, it can be dispensed with a subsequent drying of the wipes. Experiments have shown that with each wash an energy saving of more than 3 kWh / kg wipe can be realized.

Die Bikomponentenfasern sind zumindest teilweise in endlose Elementarfasern aufgespaltet Durch diese konkrete Ausgestaltung kann ein Vliesstoff mit sehr feinen Elementarfasern geschaffen werden. Die Aufspaltung kann beispielsweise mittels eines Wasserstrahlvernadelungsverfahrens erfolgen, wobei die Elementarfasern noch zusätzlich untereinander verschlungen werden. Hierdurch kann der Vliesstoff verfestigt werden. Dabei ist vorteilhaft, dass die Elementarfasern eine größere Oberfläche als die ungesplitteten Bikomponentenfasern bei gleichbleibendem Flächengewicht des Vliesstoffs bieten. Durch die Oberfläche kann der Dotierstoff nach außen in Wechselwirkung treten,The bicomponent fibers are at least partially split into endless elementary fibers. By this specific embodiment, a nonwoven fabric with very fine elementary fibers can be created. The splitting can take place, for example, by means of a water-jet needling method, wherein the elementary fibers are additionally entwined with each other. This allows the Nonwoven fabric are solidified. It is advantageous that the elementary fibers provide a larger surface area than the unsplit bicomponent fibers with a constant basis weight of the nonwoven fabric. Through the surface, the dopant can interact to the outside,

Die Bikomponentenfaser ist als PIE-Faser ausgestaltet. Durch diese konkrete Ausgestaltung kann eine relativ grobe Bikomponentenfaser in sehr feine Etementarfasern mit kuchenstückartigen bzw. kreissegmentartigen Querschnitten aufgespalten werden. Lediglich beispielhaft sei an dieser Stelle auf die DE 697 25 051 T2 hingewiesen, welche ein Verfahren beschreibt, in dem PIE-Fasern hergestellt und aufgespalten werden.The bicomponent fiber is designed as a PIE fiber. By this specific embodiment, a relatively coarse bicomponent fiber can be split into very fine Etementarfasern with cake piece-like or circular segment-like cross-sections. For example only at this point on the DE 697 25 051 T2 which describes a method in which PIE fibers are produced and split.

Der Vliesstoff weist eine Färbung auf. Überraschend wurde festgestellt, dass ein antimikrobiell ausgerüsteter Vliesstoff eingefärbt werden kann und dennoch seine antimikrobielle Wirkung beibehältThe nonwoven fabric has a color. Surprisingly, it has been found that an antimicrobially finished nonwoven fabric can be dyed and yet retains its antimicrobial effect

Folglich ist die genannte Aufgabe gelöst.Consequently, the stated object is achieved.

Besonders vorteilhaft können die Elementarfasern als Mikrofilamente einer Feinheit von 0,05 bis 1 dtex ausgestaltet sein. Mikrofilamente einer solchen Feinheit stellen eine besonders große Kontaktoberfläche für Bakterien und Sporen zur Verfügung.The elementary fibers can be designed particularly advantageously as microfilaments of a fineness of 0.05 to 1 dtex. Microfilaments of such fineness provide a particularly large contact surface for bacteria and spores.

Der Dotierstoff könnte nur in einer Komponente des Faserkörpers homogen verteilt sein. Durch diese konkrete Ausgestaltung kann beispielsweise der Mantel einer Kem-Mantel-Endlosfaser aufgeschmolzen werden, um sich mit weiteren Endlosfasern zu verbinden, ohne dass der im Kem vorliegende Dotierstoff negativ beeinträchtigt wird. Vor diesem Hintergrund ist denkbar, dass auch Side-by-Side-Bikomponentenendlosfasern verwendet werden. Des Weiteren ist denkbar, Island-in-the-Sea-Bikomponentenendliosfasern zu verwenden.The dopant could be homogeneously distributed only in one component of the fiber body. By means of this specific embodiment, it is possible, for example, to melt the sheath of a core-sheath continuous fiber in order to connect to further endless fibers without adversely affecting the dopant present in the core. Against this background, it is conceivable that side-by-side bicomponent endless fibers are also used. It is also conceivable to use Iceland-in-the-Sea bicomponent fiber end-products.

Der Dotierstoff könnte in einer Konzentration von mindestens 200 ppm im Vliesstoff vorliegen. Überraschenderweise hat sich gezeigt, dass bereits eine derart geringe Konzentration des Dotierstoffes eine antimikrobielle Wirkung gegen Viren, Sporen oder Bakterien entfalten kann.The dopant could be present in a concentration of at least 200 ppm in the nonwoven fabric. Surprisingly, it has been found that even such a low concentration of the dopant can develop an antimicrobial action against viruses, spores or bacteria.

Der Dotierstoff könnte in einer Konzentration von höchstens 500 ppm im Vliesstoff vorliegen. Die Wahl dieser Konzentration hat sich als vorteilhaft erwiesen, um einem eingefärbten Vliesstoff eine dauerhafte Reaktivität zu verleihen. Durch die Einfärbung wird der Dotierstoff zwar abgeschirmt, durch die genannte Konzentration kann er jedoch seine Wirkung noch in ausreichendem Maße entfalten.The dopant could be present in a concentration of at most 500 ppm in the nonwoven fabric. The choice of this concentration has been found to be advantageous to give a dyed nonwoven durable reactivity. Although the doping is shielded by the coloring, it can still exert its effect to a sufficient extent by the said concentration.

Die Bikomponentenfaser könnte eine Komponente aus Polyamid oder Polyethylen und eine Komponente aus Polyethylenterephtalat oder Polyester aufweisen, Durch diese konkrete Ausgestaltung ist es problemlos möglich, die Bikomponentenfaser durch Wasserstrahlen in Elementarfasern aufzuspalten.The bicomponent fiber could be a component of polyamide or polyethylene and a component of polyethylene terephthalate or polyester By this specific embodiment, it is easily possible to split the bicomponent fiber by water jets in elementary fibers.

Vor diesem Hintergrund könnte die Bikomponentenfaser 30% Polyamid oder Polymethylen aufweisen. Der Anteil an Polyethylentenephtalat oder Polyester beträgt im Wesentlichen 70 %.Against this background, the bicomponent fiber could comprise 30% polyamide or polymethylene. The proportion of polyethylene terephthalate or polyester is essentially 70%.

Der Dotierstoff könnte in der Komponente des Faserkörpers homogen verteilt sein, die Polyethylenterephtalat oder Polyester aufweist. Polyethylenterephtalat und Polyester haben sich als besonders geeignete Medien zur Aufnahme des Dotierstoffes erwiesen. Aufgrund des höheren Massenanteils der Komponente, die Polyethylenterephtalat oder Polyester aufweist, kann eine effektivere Volumenverteilung des Dotierstoffs im Vliesstoff erzielt werden.The dopant could be homogeneously distributed in the component of the fiber body comprising polyethylene terephthalate or polyester. Polyethylene terephthalate and polyesters have proven to be particularly suitable media for receiving the dopant. Due to the higher mass fraction of the component comprising polyethylene terephthalate or polyester, a more effective volume distribution of the dopant in the nonwoven fabric can be achieved.

Der Dotierstoff könnte als Element einer Nebengruppe, insbesondere der Nebengruppe lb des Periodensystems der Elemente, ausgestaltet sein. Nebengruppenelemente zeichnen sich durch antimikrobielle Wirkung aus. Vor diesem Hintergrund ist denkbar, dass mehrere Nebengruppenelemente gemeinsam in dem Faserkörper vorliegen, um unterschiedlichen Bakterienarten selektiv zu begegnen. Es hat sich in Versuchsreihen gezeigt, dass sich in Bezug auf die antimikrobielle Wirksamkeit eine Rangfolge der verwendeten Stoffe ergibt. Diese lässt sich wie folgt darstellen. Silber ist der wirksamste Stoff, gefolgt von Quecksilber, Kupfer, Cadmium, Chrom, Blel, Kobalt, Gold, Zink, Eisen und schließlich Mangan. Das gleiche gilt für Salze und Komplexe der genannten Elemente bzw. Stoffe.The dopant could be configured as an element of a subgroup, in particular subgroup 1b of the Periodic Table of the Elements. Subgroup elements are characterized by antimicrobial activity. Against this background, it is conceivable that several subgroup elements are present together in the fiber body in order to selectively counteract different bacterial species. It has been shown in test series that there is a ranking of the substances used in terms of antimicrobial effectiveness. This can be represented as follows. Silver is the most effective substance, followed by mercury, copper, cadmium, chromium, blel, cobalt, gold, Zinc, iron and finally manganese. The same applies to salts and complexes of the named elements or substances.

Der Dotierstoff könnte vor diesem Hintergrund als Silber, Gold oder Kupfer ausgestaltet sein. Diese Elemente zeigen eine besonders zuverlässige antimikrobielle Wirkung und sind kommerziell problemlos als feine Partikel erhältlich.The dopant could be designed against this background as silver, gold or copper. These elements show a particularly reliable antimicrobial effect and are readily available commercially as fine particles.

Der Vliesstoff könnte ein Flächengewicht von mindestens 20 g/m2 aufweisen. Dieses Flächengewicht hat sich als besonders vorteilhaft erwiesen, um Wischtücher herzustellen.The nonwoven fabric could have a basis weight of at least 20 g / m 2 . This basis weight has proved to be particularly advantageous for producing wipes.

Der hier beschriebene Vliesstoff kann problemlos in Kontakt zur menschlichen Haut stehen. Vorteilhaft weist der hier beschriebene Vliesstoff eine derart geringe Konzentration eines Dotierstoffs auf, dass die menschliche Haut nicht gereizt wird. Insbesondere Neurodermitispatienten bedürfen eines schonenden Vliesstoffes, wie es hier beschrieben ist. Dennoch zeigen die Endlosfasem auch auf der Filamentoberfläche eine ausreichende Konzentration des Dotierstoffs, um Bakterien, Viren und Sporen abzutöten.The nonwoven fabric described here can easily be in contact with human skin. Advantageously, the nonwoven fabric described herein has such a low concentration of a dopant that the human skin is not irritated. In particular eczema patients require a gentle nonwoven fabric, as described here. Nevertheless, the continuous fibers also show a sufficient concentration of the dopant on the filament surface in order to kill bacteria, viruses and spores.
