Description

The invention relates to a flat mop cover according to the preamble of patent claim 1.

From the JP 2010 150 708 A It is known to hold two yarn halves together by an adhesive layer containing an active ingredient. From the WO 2006/119 391 A1 is a flat mop cover known which is impregnated with an antimicrobial active ingredient. The DE 102 35 305 A1 discloses a wet floor mop. The WO 95/22 277 A1 shows another device for cleaning. From the US 2004/200 591 A1 is a fibrous material known with carbon fibers. The US 2003/0157147 A1 shows a wipe which has silver.

From the WO 02/071 914 A1 For example, a textile sheet is known that can be used as a cover for a mop. This textile layer has yarns in which silver is incorporated. In particular, the layer has loops formed out of the layer.

From the DE 20 2004 020 313 U1 a flat mop cover is known to which an active ingredient is assigned, which inhibits or suppresses the growth of bacteria and / or viruses. In concrete terms, silver ions are proposed which exhibit antibacterial and antimicrobial properties. The known flat mop cover has fibers which are coated with silver.

In the embodiment according to the US 4,010,511 a cleaning oil is applied to the wiping material, wherein the cleaning oil may be provided with antimicrobial agent.

Also at the EP 0 909 549 A1 An antimicrobial fluid is applied to the fibers.

In the US 2008/0016640 A1 An antimicrobial agent is incorporated into a foam.

In the flat mop cover known from the prior art, it is disadvantageous that the antimicrobially active substance is released relatively easily to the environment.

After just a few washes, the silver coating is almost completely removed from the fibers. The mop cover can therefore no longer develop its antimicrobial or antibacterial effect.

The invention has for its object to design a flat mop cover of the type mentioned and further, that the antimicrobial active substance remains as long as possible in the flat mop cover, the mop cover particularly quickly absorbs dirt from wet surfaces.

The present invention achieves the aforementioned object by the features of patent claim 1.

An inventive flat mop cover for placement on a mop cover holder comprises an elongated base body, wherein the base body is associated with an active substance which inhibits or suppresses the growth of bacteria and / or viruses, wherein the main body fibers, yarns or fringes are assigned and wherein the active ingredient within of the material of which the fibers, yarns or fringes are made.

According to the invention, it is provided that the fibers, yarns or fringes have a free end, which is zuwendbar the surface to be cleaned.

According to the invention, it has first been recognized that the active substance must be distributed within the material from which the fibers, yarns or fringes are made so that it remains as long as possible on the flat mop cover. It is also or alternatively important that the active substance is incorporated within the constituent, namely incorporated in it.

Washing processes then only very slowly release the active ingredient so incorporated from the matrix of fibers, yarns or fringes or the component. Advantageously, a flat mop cover still shows an antimicrobial effect after 200 - 1300 wash cycles at 60 ° C, especially in disinfecting washes.

It has further been recognized that fibers, yarns or fringes having a free end act as a type of wick along which dirt easily dissipated in the water can be transported and / or bonded. If the free ends of a moist, to be cleaned surface are turned, dirt particles are surprisingly easily absorbed by the fibers, yarns or fringes.

The recorded dirt or dirt particles that come in contact with the antimicrobial agent, so that the formation of unpleasant odors, the formation of mold or fungi is effectively suppressed or reduced even before the most daily made disinfecting laundry.

The free ends, in contrast to closed ends and / or loops, not only a wicking effect, which the dirt and Accelerating water transport in the flat mop cover, it is also prevents the fibers, yarns or fringes from sticking to rough structures. In particular, in the cleaning of wood floors with splinters or nails or in the cleaning of security tiles such rough structures can occur.

The flat mop cover according to the invention therefore allows easy cleaning of floors. In that regard, a flat mop cover is specified, which easily absorbs dirt from a wet surface and is characterized by a durable wash resistance.

The active ingredient is distributed homogeneously within the material. For this purpose, the active ingredient according to the invention is introduced into a melt of polyester, polyamide, polypropylene or similar materials common for fiber production. After homogeneous distribution of the active ingredient in the melt, fibers, in particular microfibers, can be produced by extrusion. The active ingredient is then uniformly distributed homogeneously within the fiber body. This ensures a gradual release of the active ingredient to the environment.

Against this background, the active ingredient is present in a fiber, a yarn or a fringe with a weight fraction of 0.0001% to 2%, preferably from 0.001% to 0.05%. The first area ensures that on the one hand a sufficient antimicrobial effect is ensured, and on the other hand, the flat mop cover is washable about 200 to 1300 times at 60 ° C, without losing its antimicrobial effect. The second range of 0.001% to 0.05% ensures that, although an antimicrobial effect is given, but on the other hand, only relatively little antimicrobial active ingredient is released into the environment.

Against this background, the drug could be nanoscale. An active substance that is present in nanoscale has particles whose maximum diameter is less than or equal to 1 μm. An active substance, which is nanoscale, provides a particularly large surface area and can therefore interact particularly well with bacteria, viruses or germs.
The active agent could comprise elemental silver or another subgroup element. The active ingredient could be present as elemental silver. Elemental silver is particularly easy to process in a melt. The active ingredient could comprise at least one sub-group element. Subgroup elements are characterized by antimicrobial activity. Against this background, it is conceivable that several subgroup elements are present together in the active ingredient 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. In addition to silver, mercury, copper, cadmium, chromium, lead, cobalt, gold, zinc, iron and finally manganese are known. Against this background, it is conceivable to use also main group elements which show an antimicrobial effect.
The antimicrobial agent could comprise a gold-silver mixture or consist solely of a gold-silver mixture. Mixtures of this type show a particularly high antimicrobial Effectiveness. It has surprisingly been found that the presence of gold further enhances the antimicrobial effect of silver. Against this background, it is conceivable to dope silver with gold. It is also conceivable to form islands or clusters that comprise either only gold or only silver but also mixtures of these substances. In this case, islands or clusters of different composition can coexist.

The active ingredient could be aluminum added. Aluminum causes a long-term brightening and / or improved appearance, since, for example, silver is turning brown due to oxidation processes. Aluminum also causes a modification of the release rate of the antimicrobial agent.

The active ingredient could be present as a silver salt. Silver salts can be easily dissolved and processed.

The active ingredient could be incorporated in a ceramic carrier. The active substance is preferably absorbed in a ceramic ball. The ceramic carrier ensures that the active ingredient is readily dispersible within a melt. By using a ceramic carrier mixing problems can be avoided.

The active ingredient could be in a fiber, yarn or fringe having a weight fraction greater than or equal to 0.001%. A flat mop cover of this embodiment can be used as a disposable product. Such a flat mop cover is only a few times, a maximum of 100 times washable, but shows no stable antimicrobial effect at 100 - 1500 wash cycles.

The flat mop cover could have at least one base layer on which the fibers, yarns or fringes are fixed, in and / or on the Base, an active ingredient is distributed, which inhibits or suppresses the growth of bacteria and / or viruses. This concrete embodiment ensures that mold or fungus formation is also prevented in the area of the base layer. The active ingredient used in the base layer may be present in the aforementioned concentrations and properties. After completion of a cleaning process, the fibers, yarns or fringes are often on the base layer. In a base layer provided with an antimicrobial active agent, the fibers, yarns or fringes may be protected from mold growth by the base layer in addition to their intrinsic antimicrobial finish.

The active ingredient, which is assigned to the base layer, unfolds its antimicrobial effect in a moist or wet environment even over a certain distance. Experiments have shown that thereby also other parts of the flat mop cover, which were not equipped antimicrobial in the experiment, are protected from germ growth. Against this background, it is also possible that the mop cover holder can also be at least partially protected from germ growth by contact with the antimicrobial flat mop cover. The flat mop cover creates a kind of antimicrobial action in the humid environment at small distances, namely in the millimeter range, by delivering the silver ions into the moist environment.

Against this background, the active ingredient could be assigned to the main body in such a zone-wise manner that the zones in which the active ingredient is present form a pattern. As a result of this specific embodiment, areas of the body which are more heavily stressed can be reinforced with the active ingredient.

The fibers, yarns or fringes could include microfibers. Microfibers have diameters in the range of 1 to 100 microns. Microfibers can be produced by extrusion. Furthermore, microfibers can be produced by splitting multicomponent fibers.

At least one pocket could be arranged on the base body into which a receptacle of a mop cover holder can be inserted. By this specific embodiment, for example, a so-called "butterfly" - or "pockets" - mop can be connected to the flat mop cover. Such a mop cover has two mutually pivotable wings, which can be inserted into two pockets of the flat mop cover. The pockets are arranged at the longitudinal ends of the elongated base body of the flat mop cover.

On the main body tabs could be arranged, which are non-positively or positively inserted in receiving devices of a mop cover holder. The tabs are arranged for this purpose in the region of the longitudinal ends of the elongate base body. The tabs can be placed around a wing of a mop cover holder such that the flat mop cover experiences a tension. The tabs can be inserted into bracket-like gaps on the wings of a mop cover. Thus, a positive connection between the tabs and a wing of a mop cover holder takes place.

The basic body could be assigned area areas which can be applied positively to receiving areas of a mop cover holder. Against this background, it is concretely conceivable that receiving areas are formed on the underside of a wing of a mop cover holder. The receiving areas could cooperate with the flat areas on the base body such that a hook-and-loop closure is formed. Furthermore is conceivable to provide so-called Velcro fasteners on the surface areas and on the receiving areas.

A mop cover holder could have a flat mop cover of the type described here. Such a mop cover holder is characterized by a pronounced antimicrobial effect. The active substance incorporated in the fringes of the mop cover unfolds its antimicrobial effect in a moist or wet environment, even over a certain distance.

Experiments have shown that this also protects other parts of the flat mop cover, for example the base layer, the tabs or the flat areas, which were not antimicrobially equipped in the context of a test arrangement, from germ growth.

Against this background, it is also possible that the mop cover holder can also be at least partially protected from germ growth by contact with the antimicrobial flat mop cover. The mop cover creates a kind of antimicrobial action in the humid environment at small distances, namely in the millimeter range, by delivering the silver ions into the moist environment.

The flat mop cover could be designed as a velor flat mop cover. A velor material is produced in which a yarn of several fibers is assigned to a base layer.

The flat mop cover could have fringes. Such a mop cover may be made by tufting or pocketing. Such flat mop covers can be made relatively easily. In the formation of the tufts fringes or strands are made of several yarns, preferably made of six interwoven yarns, sewn to a base layer.

There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to the subordinate claims, on the other hand, to refer to the following explanation of preferred embodiments of the flat mop cover according to the invention with reference to the drawing.

In connection with the explanation of the preferred embodiments with reference to the drawing, also generally preferred embodiments and developments of the teaching are explained.
