Abstract

The cleaning cloth (1) has a storage layer (6) and a cleaning layer (3). The cleaning cloth is formed as multi-layered. The cleaning layer is formed on a textile base with a supine position and pile yarn anchored to the base. The textile supine position has low fluid permeability than the storage layer.

Description

The invention relates to a cleaning cloth for a floor wiper device, in particular for a motor-driven floor wiper device, preferably for attachment to a driven oscillating body of the floor wiper device, wherein the cleaning cloth is multi-layered and has a storage layer and a cleaning layer, wherein moreover the cleaning layer is formed on a textile basis with a supine position and pile threads anchored therein.

Cleaning wipes of the type in question are known. These serve, for example, the soil moist cleaning, for which purpose they are arranged on a corresponding floor mop. For preferably continuous dispensing of liquid, for example cleaning liquid or else water, such cleaning cloths have a storage layer for the liquid, which storage layer continuously delivers subsets of the stored liquid to the cleaning layer, via which the wiping process, if necessary additionally a mechanical treatment of the to be cleaned Surface done. Such cleaning layers are preferably based on a textile design, further possibly using synthetic fibers, wherein free pile threads, including loops, are anchored in a textile backsheet of the cleaning layer. It is also known in this context to connect the cleaning layer with the storage layer, for example, to sew together.

Next, commercial cleaning tissues are known, which differ greatly depending on the application. This difference manifests itself, for example, in different textile constructions (flat fabric, plush), in the yarn materials used (eg microfiber) and fiber raw materials (cotton, viscose, polyester). Combinations of different raw materials and textile constructions are also used to tailor the textiles perfectly to their intended purpose. For example, the favorable cleaning effect of a microfiber plush of polyamide and / or polyester combined with the good water absorption / distribution of a nonwoven fabric of viscose and polyester.

In view of the above-described prior art, a technical problem of the invention is seen in further improving a cleaning cloth of the type in question, in particular with regard to the range of a cloth provided with liquid, taking into account a continuous fluid delivery from the storage layer into the cleaning layer.

This problem is solved first and foremost by the subject matter of claim 1, wherein it is pointed out that the textile backing has a lower liquid permeability than the storage layer. As a result of this embodiment, the fabric backing of the cleaning layer anchoring the pile threads acts in the manner of a brake layer for the liquid continuously drained from the storage layer into the cleaning layer. Thus, in this context, it is further preferred that, according to the selected fiber material and the adjusted weave density of the supine layer of the cleaning layer, a liquid transport from the storage layer is limited such that only 10 g of liquid are moved when the bottom wiper device moves over an area of 15 m ² to 25 m ² or less (for example, up to 3 g) per square meter. Thus, according to the proposed embodiment of the textile backing a fog-damp cleaning of hard floors in particular achievable, this more preferably over an area of at least 20 m ² , more preferably also on different floors, with a subsequent addition of liquid for processing such a surface is not necessary. In addition, the liquid transport regulating textile backing allows the application of the cleaning cloth to floor wipers having a driven vibrating body. The cleaning cloth is to be attached to these. Such Bodenwischgeräte act alone by their own weight of 5 to 10 kg according to the cleaning cloth. The proposed embodiment of the textile backing even with such a pressurization uniform liquid delivery to the cleaning layer and can be reached on this to be cared for soil. Thus, it was further found in this context that under the mechanical action of such a floor wiper device with a weight of about 6 kg, a resonant circuit diameter of 16 mm and a speed of 1500 rpm, a uniform liquid discharge is achieved.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. But they can also be in an assignment to only individual features of claim 1 or the respective further claim or each independently of importance.

The wiping speed exerted by the user on the floor wiper device is preferably between 0.5 and 1.5 m / s, the release of the cleaning fluid being designed for this speed range. At a preferred wiper speed as described above and a liquid delivery to the floor of preferably 4 g / m ² , with a preferred cloth width of 300 mm, a permeability of the supine position of preferably 0.6 to 1.8 g / s is provided. The values for the absorption capacity of liquid through the storage and cleaning layer are determined by DIN 53923 , The preferred maximum liquid absorption of the cleaning layer is therefore from 1 to 10 times, preferably from 5 to 6 times the weight of the material. The storage layer preferably has a maximum liquid absorption, which corresponds to 5 to 20 times, preferably 9 to 11 times, the material weight of the storage layer. In this case, the basis weight of the cleaning layer is preferably between 1,000 and 1,500 g / linear meter at a reference width of about 150 to 170 cm, resulting in a basis weight of about 500 to 1,000 g / m ² results.

The cleaning layer fulfills several functions. It is responsible for the cleaning performance (dirt solution / binding). It is characterized by the necessary robustness to ensure a long service life even on different floors. In addition, this preferably provides in combination with a driven oscillating body of the floor wiper device for the necessary smooth running of the device. As a fabric construction is preferably a 3D-textile structure such as plush (velor or sling), alternatively, a 2D-textile structure such as woven fabric (cotton cloth) or non-wovens (nonwovens). Further preferred cleaning plushes are in this regard. It is further preferred that a possibly existing preferred direction (pile / polar direction) does not adversely affect the smooth running of the device. Thus, more preferably, the polar direction is designed so that it contributes to the smoothness of the device. Preference is further given to a cleaning layer without polar direction, further in particular by producing a three-dimensional textile cleaning layer by tufting. In this context, it is further preferred that the lower liquid permeability is achieved by a high weaving density of the textile supine. Correspondingly, a high number of warp and weft threads per unit area, for example, per square centimeter is provided, which act correspondingly close to each other or crosswise extending threads braking on the liquid transport between storage layer and cleaning layer or between storage layer and surface to be cleaned. Thus, it is further preferred that the weave density of the textile backsheet is selected in the range of 12 to 20 warp threads per centimeter and 15 to 25 wefts per centimeter, more preferably at a fiber thickness of 0.01 to 4 dtex, more preferably 0.1 to 2.0 dtex. Thus, in a further preferred embodiment, 17 warp threads per centimeter and 19 weft threads per centimeter or 14.5 warp threads per centimeter and 19.5 weft threads per centimeter are provided.

The overall thickness, in particular when the pole of the cleaning layer is upright including the supine position, is in a further preferred embodiment 3 mm to 30 mm, more preferably 5 mm or even 17 mm, furthermore the prescribed dimensions tolerances in the range of 3% to 10%, more preferably 5% can have.

The fibers of the cleaning layer are preferably selected from synthetic fibers of polyester, more preferably in different thicknesses of 0.01 to 4 dtex. Further, the fibers of the cleaning layer may also be selected from cotton. Furthermore, in particular the wear layer of the cleaning layer (Pol) contains both microfiber components and also fibers with larger thicknesses in order to combine the required cleaning performance with a sufficient degree of robustness. It proves to be advantageous if the different types of fibers in the yarn are mixed together. Thus, it is further provided in this connection that 10% to 20% of the fibers consist of microfibers, for example micropolyesters. The formation of the pile fabric exclusively of micropolyester proves to be beneficial. Further, in a preferred embodiment, the pile fabric is formed of 85% polyester and 15% micropolyester. As an alternative, 70% polyester is possible as well as 100% polyester.

The backsheet has fibers selected from polyester and / or cotton. Thus, a fiber blend of 60% to 80% polyester and 40% to 20% cotton, more preferably 77% polyester and 23% cotton is preferred. Alternatively, the textile backsheet is made of 100% polyester.

The supine position is functionally connected to the cleaning layer. It forms the mounting position for the, the cleaning layer forming pole. An alternative to the embodiment as a thread structure forms, for example, a back bonding of the pile threads. Another alternative for influencing or adjusting the parameters for the liquid permeability, in particular the backing layer, is in addition to the mentioned warp / weft ratio in the application of an equipment. By adjusting the hydrophilic or hydrophobic properties, the permeability can be influenced independently of the properties of the individual layers. By way of example, a storage layer which tends to give off the liquid to a great extent can be braked by means of targeted equipment of the subsequent layer so far that the target for the liquid delivery to the cleaning layer is achieved.

The storage layer is essentially responsible for ensuring that controlled liquid intake takes place during dosing and that no liquid leaves the cleaning cloth in an uncontrolled manner during assembly / attachment of the cleaning cloth to the floor mop, for example on the support plate-like oscillating body. The liquid is absorbed quickly and evenly during dosing. The amount of liquid required for the cleaning process is applied in a preferred embodiment via corresponding humidifying directly to the storage layer.

During operation of the floor wiper device, the storage layer discharges the liquid evenly to the cleaning layer. Only through the arrangement of a storage layer and a braking action of the cleaning layer, the required uniform moistening of, for example, up to 20 m ^{2 is} possible. Without a storage layer or a braking supine, too little liquid would be dispensed on the first square meter and too little on the last square meter. Accordingly, without a storage layer, more preferably without a braking supine, neither a damp cleaning nor the required range to achieve.

In a preferred embodiment, the total thickness of the storage layer is 1 mm to 10 mm, more preferably 2 mm to 4 mm. The storage layer preferably consists of a fleece and / or plush material which is composed of water-storable fibers, preferably selected from viscose or cotton. Further, structuring synthetic fibers of polypropylene or polyethersulfone are added, more preferably 10% to 30% of the total fiber content. Thus, the storage layer further preferably consists of 70% to 90% viscose and 30% to 10% polypropylene, more preferably 80% viscose and 20% polypropylene.

In a further embodiment, the storage layer is formed in multiple layers, so for example. Consisting of two to six, preferably four individual layers with a basis weight of 20 to 100 g / m ² , which lie loosely on one another, alternatively optionally selectively bonded or sewn together or quilted ,

The storage layer is matched in its shrinkage behavior on the cleaning layer, so that a disadvantageous for the use or handling change in shape of the cleaning cloth is largely prevented. The storage layer is preferably permanently connected to the cleaning layer, for example, sewn thereto, but may alternatively be made detachable from the cleaning layer.

Since high frictional forces act on the back of the cleaning cloth by the floor mop device, in particular in the case of a driven oscillating body, the cloth construction is further designed so that the cleaning cloth does not suffer any damage during operation. For this purpose, for example, a surface refinement is carried out, in particular of the surface of the storage layer facing the device, and / or very robust material is used. Alternatively, the application of a protective cover is provided, for example, formed as a smooth garniture of 100% PES with a fabric structure of 15 to 25, preferably 21 warp / cm and 5 to 15, preferably 10 weft / cm at a basis weight of 150 to 200, preferably 180 g / m ² .

In a further preferred embodiment, the cleaning cloth has a rectangular ground plan, more preferably an elongated rectangular floor plan with a longitudinal extent and a transverse width directed transversely thereto, an extension dimension in the longitudinal extent of 1 to 5 times, more preferably 2 to 3 times of the measure in width extension corresponds. Furthermore, the cleaning cloth is preferably adapted in terms of area to the preferred oscillating body of the floor wiper device, so that the cleaning cloth covers the oscillating body over the entire surface. Thus, in a device-side support plate for fixing the cleaning cloth having a plate dimension of 220 to 300 mm × 100 to 160 mm, preferably 260 × 130 mm, a cleaning cloth having a longitudinal extent of 260 to 340 mm, preferably 300 mm, and a transverse extent of 130 to 190 mm, preferably 160 mm, provided, wherein further considered perpendicular to the surface extension of the cleaning cloth height of the same 7 to 10 mm.

The cleaning cloth has in a further embodiment along a longitudinal and / or transverse edge on a bordürenartige edge enclosure, which surrounds at least the storage layer in cross-section U-shaped. This edging is more preferably a textile shape, further example. In the form of along the longitudinal and / or transverse edge or a total circumferential bead. In this case, in a further preferred refinement, the edge bordering has a width which corresponds to 0.05 times to 0.1 times the width of the cleaning cloth, measured transversely to the marginal edges, without marginal edging. The height of the cleaning cloth in the region of the edge border further corresponds to 1 to 4 times the width of the border, this in each case based on an uninfluenced state of the border. Thus, a width of 10 mm to 30 mm, more preferably 15 to 25 mm, considered transversely to the longitudinal extent of the edge border is provided and a vertically considered, further considered perpendicular to the surface extension of the cloth height of 10 mm to 20 mm.

The edge surround further preferably circumscribes at least the storage layer, this also encompassing along the edge at the same time a subregion of the edge confining width. In a further embodiment, the edge enclosure may also include the textile backsheet of the cleaning layer.

In particular, in an embodiment of the edge enclosure, in which this overlaps the storage layer on the edge, is in the assignment position of the cleaning cloth on the support plate of the floor wiper device, for example. On the oscillating body a distance of the support plate surface to the facing surface of the storage layer reached. In addition, a pinch protection is thereby realized, which acts in the Festlegungsstellung the cleaning cloth on the device. In order to further improve such a clamping protection, it is provided that the edge enclosure is designed to be elastically deformable, for example by designing the edge enclosure of an elastically adjusted soft plastic material. In a preferred embodiment of the edging as a textile structure, this is initially formed as a wrapping layer, further correspondingly tubular, in which envelope an elastic material, for example. A resilient foam is added. According to this embodiment, the edge surround also represents a shock absorber, the z. B. acts in a strong joint offset or protects against edge damage furniture pieces and / or equipment.

The edge processing is preferably implemented by a survival of the cleaning cloth on the device-side support plate. In addition, the supernatant can also be realized by the cleaning layer itself or further, for example, by arranging additional edge-side fringes or the like.

To fix the cleaning cloth to the device, for example. On a support plate or vibrating disk of the device are formed in a preferred embodiment on a device side back of the cleaning cloth, more preferably on the cleaning layer facing away from the surface of the storage layer over the width and / or length attachment means. These act together in appropriate assignment position with attachment counterparts of the device, more preferably the assignment position is unique. In this regard, it makes sense to provide over the length and / or width of the device-side back of the cleaning cloth several fasteners that are the same shape, but alternatively designed differently.

In order to use the above-described edge enclosure also in connection with the above-described fasteners as anti-jamming and / or shock absorbers, it is preferred that the edge enclosure at least partially surmounting the attachment means of the cleaning cloth in width and / or longitudinal extension, more preferably also in the direction perpendicular to the surface extension the fabric having the fastening means. Thus, it is provided in a further preferred embodiment that the edge enclosure is provided circumferentially along the longitudinal and narrow edge edges of the cleaning cloth and the fastening means are positioned within the area so spanned. Correspondingly, in a preferred embodiment, the edge trim represents the outer contour of the cleaning cloth. Preferably, no cloth and / or fastener portions relevant to the machining position extend beyond the edge trim to the outside.

A fastening means is further preferably formed from a receiving pocket, in which a free end of a device-side support plate can be inserted. This insertion is preferably stop-limited, more preferably such a receiving pocket is provided in the region of a narrow edge of the cleaning cloth. The receiving pocket can be formed by folding over a corresponding end region of the storage layer, wherein the cover edge forms the receiving pocket bottom and thus forms a stop limit for inserting the carrier plate. In addition, in a further preferred embodiment, the receiving pocket from the material, in particular from the shell material of the edge enclosure is formed, wherein a longitudinal edge of the receiving pocket is connected to a narrow side of the edge enclosure and extending perpendicular thereto narrow edge edges of the receiving pocket with associated areas of the edge enclosure longitudinal sides. According to this embodiment, a three-sided closed receiving pocket is formed. This preferably extends over the entire, viewed transversely to the longitudinal extent of the cleaning cloth free width between the mutually parallel longitudinal edge-Randeinfassungsabschnitten, more preferably the receiving pocket has a depth of insertion, the one tenth to a quarter, further example. One-fifth in the same direction considered longitudinal extension of the cleaning cloth corresponds.

An alternative or combiner provided to the receiving pocket fastening means is formed from the loop or hook position of a hook and loop fastener. Accordingly, the fastening means is formed as an adhesive element. It can be arranged on the cleaning layer facing away from the surface of the storage layer a plurality of such designed attachment means, so for example. Two fastening means, each optionally associated with distance the narrow edge sides of the cleaning cloth. When combined with a receiving pocket and a fastening means in the form of an adhesive, the latter is preferably provided in an edge region of the cleaning cloth opposite the receiving pocket. The counterpart (hook or loop position) is positioned accordingly on the associated mounting surface of the device, for example. On the support plate. The formation of a hook and loop fastener a detachable connection is achieved.

So that the user does not come into direct contact with the cleaning cloth, in particular with the cleaning layer soiled after cleaning, in a further preferred embodiment, a grasping element is provided, which is provided projecting the edge of the cleaning cloth, more preferably at the same time. The gripping element is in this case, for example, designed in the form of a tab or a bracket, more preferably as a flat structure, more preferably in a plane parallel to the cleaning fabric level. The Anfasselement is due to the proposed supernatant to capture cheap and serves in another embodiment at the same time as additional security and beyond as a carrying handle and positioning aid.

Alternatively, the Anfasselement example. Film-like made of a plastic material, which is on the back of the cleaning cloth, further example. In the area of the associated edge enclosure is fixed, for example. According to gluing or welding, alternatively by sewing.

The gripping element further preferably has an inherent rigidity, according to which this remains when using the cleaning cloth at a distance from the effective plane of the cleaning layer, further away from the ground in the operating position of the cleaning cloth when it is arranged on the device. Accordingly, the grasping element does not act on the floor to be cleaned, which could leave marks on the floor, which is preferably left to damp.

The arrangement of the Anfasselementes is further chosen so that this is associated with a longitudinal or narrow edge edge of the cleaning cloth. In a preferred embodiment, the gripping element is provided on an edge opposite the attachment pocket, whereby a favorable handling, in particular in the course of attachment to, further in the course of removal of the device is achieved. Thus, according to the proposed arrangement of the Anfasselementes means of the latter, the cleaning cloth on a support plate of the device can be pulled up by a free end of the support plate is placed in the opposite to the Anfasselement provided receiving pocket. Also, the touch element proves favorable to the solution of the more preferably provided Velcro attachment.

In a further embodiment of the cleaning cloth, this has two or more receiving pockets for cooperation with a device-side carrier plate.

The bordering 8th is preferably permanently connected to the storage layer 6 , In an alternative embodiment, the edging is 8th overall formed as a cord-shaped, elastically resilient plastic soft part.

The cleaning cloth 1 indicates on the rear side facing the device, ie, further corresponding to the back of the cleansing layer side 5 remote surface of the storage layer 6 fastener 16 on, to determine the cleaning cloth 1 on the floor mop 2 , further in particular as in 3 shown schematically on a support plate 7 of the device 2 ,

So first is a receiving bag 13 intended. This extends with its pocket opening parallel to a transverse edge 10 of the cleaning cloth 1 , where the bottom of the bag 14 directly to the edge bordering section in the region of the transverse edge 10 is assigned or through the section of the border 8th itself is formed. The receiving bag 13 extends over the entire width between the associated end portions of the longitudinal edges 9 running edge borders 8th so that with reference to a floor plan the receiving pocket 13 closed on three sides. The pocket opening points in the direction of the opposite transverse edge 10 of the cleaning cloth 1 ,

The touching element 18 is further shaped as a flat structure, for example. As a stamped foil section with a thickness of 0.5 mm to 1 mm, so that an inherent rigidity of the Anfasselementes 18 is reached. The touching element 18 protrudes outwards over the floor plan of the cleaning cloth 1 so that a hygienic handling of the cleaning cloth 1 is reached. Due to the aforementioned inherent rigidity the grasping element remains 18 also in the position of use of the cleaning cloth 1 at a distance from the floor to be cleaned.

4 shows an alternative embodiment of the cleaning cloth 1 in which for receiving a suitably designed carrier plate 7 the overall one-piece overreaching section 15 for the formation of two side-by-side receiving pockets 13 with the storage layer 6 approximately in the middle of its extension - in the width direction of the cleaning cloth 1 considered - connected. The connection is achieved in the illustrated embodiment according to a seam 19 , This extends in the longitudinal extent of the cleaning cloth 8th , for the formation of two juxtaposed, preferably equally large receiving pockets 13 , So is a shrink-independent, backlash-free positioning of the cleaning cloth 1 on the carrier plate 7 given, which latter preferably a corresponding, slot-like recess for immersing the seam area in the course of applying the cleaning cloth 1 on the device or while using the cleaning cloth 1 , If the cloth dimensions change during the life of the cloth, this seam will be used 19 the cleaning cloth 1 preferably exactly in the intended position on the carrier plate 7 centered. During device operation, the carrier plate is supported 7 in the region of the preferably provided slot-like recess on the fabric seam 19 from, bringing a relative movement between the support plate 7 and cleaning cloth 1 is avoided.

Both pocket openings 20 the so isolated receiving pockets 13 point in the same direction, further towards that also on the storage layer 6 arranged, opposite fastening means 16 ,

The circumferential border 8th , the fasteners 16 as well as the touch element 18 are preferably made of a neither capillary, nor liquid-storing material, so that on the one hand the grasping element 18 always dry and on the other hand, the edge enclosure 8th forms a water or drip stop.
