Abstract

The invention relates to a wiping element (11) that is characterised in that at least one edge of the textile cleaning material is provided with bristles (21) in order to form an edge region (19) with an improved cleaning action.

Description

Wischbezug

The invention relates to a mop cover for cleaning the floor, in particular for covering a tenter frame, with a cleaning textile having cleaning fibers on at least one side, which is arranged such that the cleaning fibers face the floor to be cleaned and form the underside of the mop cover and on at least partially a lateral edge is formed, from which cleaning fibers project laterally.

DE 4323 923 discloses a cleaning device for covering a

Tenter frame, with a textile base material, from which pile threads or loops that have a cleaning effect protrude. An elongated trim piece is attached to the base material along two spaced fastening lines along a rancL edge such that the web width of the base material between the attachment lines is greater than the corresponding web width of the trim piece. The result of this is that the base material is arched or folded between the fastening lines and a cavity is formed which can serve as a fluid reservoir or air cushion. The air cushion allows the cleaning device to better adapt to any unevenness or structure of the floor or a side obstacle.

[0003] EP-A-0 630 606 relates to a mop cover for floor cleaning with a base layer which has means for fastening to a holder on its top and is covered with a layer of wipe on the underside and in the edge region. The edge of the wipe layer is connected to a border of the top. The border of the upper side is at least partially reinforced with a reinforcement on its inner edge and fastened to the support layer in the region of the reinforcement. The mop cover of EP-A-0 630606 is said to have good dimensional stability. A disadvantage of the known mop covers that they are in grooves and

Chinks can only intervene little.

It is an object of the present invention, in particular for a

Floor cleaning device to provide certain mop cover with improved cleaning effect. In particular, the mop cover should make it possible to remove dirt even in hard-to-reach places, such as corners of floor-wall transitions and joints. Stubborn dirt should also be removable with the mop cover. Of Furthermore, no streaks should remain on the cleaned surfaces. Another goal is to provide an inexpensive mop cover. According to the invention, a mop cover according to the preamble of claim 1, characterized in that at least along one side an edge zone of the mop cover is additionally covered with bristles to form an area with an improved cleaning effect. Such an edge zone can achieve an improved cleaning effect. The bristles protruding from the rest of the cleaning surface can engage in cracks and gaps and free them of dirt. Bristles provided on the underside of the covering provide an improved scraping effect when cleaning. At least two opposite edge zones of the are advantageous

Mop cover with bristles. This has the advantage that the cleaning and scraping effect of the mop cover is further improved. The edge zone with the bristles expediently extends along the broad side of the mop cover. This has the advantage of an attack surface that is enlarged relative to the narrow sides. The bristles advantageously protrude beyond the covering formed from cleaning fibers by a certain length. The longer the bristles are, the deeper they can engage in gaps and cracks. The bristles expediently protrude beyond the remaining covering by at least 2 mm, preferably at least 4 mm and very particularly preferably at least 6 mm. According to a preferred embodiment, the edge zone of the

Mop cover with isolated bristles. This has the advantage that different cleaning effects are paired in the edge area.

Advantageously, the mop cover is rectangular, and the edge areas of the broad sides of the mop cover (long side edges) are each occupied with individual, spaced bristles. Such a mop cover corresponds to the size of conventional mop covers, but has an improved cleaning effect due to the specially designed edge zones.

According to a preferred embodiment, the mop cover is formed from three substantially rectangular individual parts, a central part and two side parts. By sewing the adjacent edges of the individual parts at a distance from the side edges, beads can be easily formed. The beads can serve as positive guides for a stenter. It has been shown that for Connecting the middle part with the two side parts one seam is sufficient, although in principle more than one seam can be provided if necessary. Preferably, the side parts have a covering made of microfibers and individual bristles projecting beyond the covering. By providing 1 to 20 bristles, preferably 2 to 15 bristles, the cleaning effect of the coating can be increased. Between 4 and 12 bristles per square centimeter are particularly preferably provided. Such a covering is particularly suitable for wet cleaning of floor slabs, tiles and the like. The bristled edge zones advantageously form a first microfiber covering, and the area located between the edge zones is a second, in particular different, microfiber covering. The first microfiber covering expediently has a lower water absorption capacity than the second microfiber covering. This allows the edge zones to loosen the dirt and the middle part of the wiping surface can absorb the dirty water. The weight per unit area of the first microfiber covering is preferably at least 10 percent by weight less than that of the second microfiber covering. Due to the lower weight per unit area, the microfiber covering of the edge zones is less dense than that of the middle section at approximately the same covering height.

[0013] Although the cleaning microfibers can in principle be made of different plastics, in particular polyester, polyamide or nylon fibers, they are preferably made of polyester. Polyester microfibers have the advantage that they have a good capillary action and therefore a good storage capacity for water. By providing fibers of less than 5 dtex, preferably <1 dtex and very particularly preferred 0.5 dtex, microfiber plaster coverings can be produced with a very good cleaning effect.

[0014] At least the first or the second microfiber covering is advantageous

Threads composed of fibers with different melting points. These threads can be subjected to a temperature treatment such that the threads are shrunk. The invention is explained in more detail with reference to the accompanying figures.

[0016] It shows Figure 1: schematically an inventive mop cover in a perspective view from above; FIG. 2: a wiper cover according to the invention in cross section; and Figure 3: schematically a partial view of the mop cover.

The mop cover 11 shown in Figures 1 to 2 has a knitted or woven textile base material 13, from which at least on one side, dei cleaning side 15, cleaning fibers 17, 17a protrude Preferably, the cleaning fibers 17, 17a of the cleaning side 15 are made of threads or loops formed, which in turn are made from a variety of microfibers. It is known that microfibers are particularly suitable for the mechanical cleaning of soiled surfaces.

The mop cover 11 shown differs from known mop covers in that opposing edge zones 19 of the mop cover are covered with bristles 21 to form an edge region with an improved cleaning effect. The bristles 21 are longer than the other cleaning fibers 17a of the edge zone 19 and protrude beyond them by a certain excess.

Individual bristles 21 are arranged in the peripheral zone 9 at more or less regular distances from one another. An average of 4 to 8 bristles 21 are preferably provided per square centimeter. The bristles 21 are anchored in the base material like the cleaning fibers 17, 17a. The bristles 21 and cleaning fibers 17, 17a can be connected to the base material, for example, by gluing or fusing.

According to an advantageous embodiment, the edge zones 21 and the middle part 23 of the mop cover located between the edge zones 21 are made of

Plaster coverings made of different densities. Particularly preferably, the microfiber covering forming the edge zones 21 has a lower density (weight / unit area) than the microfiber covering of the middle part 23. Advantageously, the microfiber covering of the middle part 23 has a greater water absorption capacity than that of the edge zones 21. This has the advantage that the middle part 23 can absorb excess cleaning water and loosened dirt when cleaning. The number of bristles per square centimeter can vary between 2 and 40 bristles. In order to achieve an optimal cleaning result, the number of bristles per square centimeter expediently ranges between 4 and 12, preferably 4 to 8 bristles per square centimeter. The edge of the mop cover is folded inwards at least once, preferably twice (FIG. 2). The inward edge area ensures increased water absorption. The cleaning fibers can be better supplied with water and dirt can be loosened. On the top of the mop cover, a longitudinal bead 25 is provided at a distance and parallel to the inwardly folded mop cover edge. This longitudinal bead can serve as a positive guide for a clamping frame 27 (Fig.2). The bead 25 can be produced by, for example, sewing folds with a seam into the cleaning textile. According to a preferred embodiment, the mop cover consists of at least three individual parts, a central part 23 and two side parts 35. The mutually adjacent edges of the parts 23, 35 are sewn together at a distance from the edge edge with a seam 31 (FIG. 2). The beads 25 are advantageously edged with a strip 36 of a hard-wearing material, for example a textile or plastic strip, as can be seen from FIG. The strip 36 gives the bead 25 in cross-section the shape of an annular bead, which can serve as a system and positive guide for a stenter.

To accommodate a known stenter are on the top of the

Mop cover provided at a distance from the narrow side edges pockets 38. The pockets 38 are formed by two substantially approximately trapezoidal trim pieces 39 with lateral ears 41. The short edge 43 of the trim piece is oriented towards the narrow side 44 of the mop cover and sewn onto the central part 33 by means of a seam 45. The ears 41 are fastened to the side parts 35 by means of seams 47.

To produce the mop cover, the

Longitudinal beads 25 formed. For this purpose, a rectangular middle part 23 and two rectangular side parts 35 are cut out of a larger piece of cleaning textile. The edges of the adjacent long side edges are sewn together in such a way that longitudinal beads 25 are formed. The beads 25 are advantageously edged with a strip 36 of a hard-wearing material. By means of a continuous longitudinal seam 23, the strips 36 can be fastened and at the same time the longitudinal beads can be formed. Next, the pockets 37 are sewn to accommodate a tenter on the top of the cleaning texti. The pockets consist of an approximately trapezoidal trim piece 39 which is sewn on the side of the cleaning text facing away from the cleaning side in such a way that the edge 43 is at a distance from the narrow side 44 of the cleaning text. The distance between the edge 43 of the trim piece 39 and the short side edge of the cleaning text is selected such that, after the edge has been folded over, an edge approximately the same width as that along the broad side of the mop cover is formed. The side ears 41 of the trim piece 39 extend over the

Longitudinal beads 25 and are connected to the cleaning textile by means of a 47. Subsequently, the opposite edges of the broad sides of the cleaning texti are folded over once or twice inwards and the envelopes formed in this way in the area of the inside bend or respectively. at a short distance from it connected to the cleaning textile by a longitudinal seam 24. The envelopes preferably extend to the respective longitudinal beads 25 and cover the ears 41 and the seams 47.

Finally, the edges of the narrow sides of the cleaning textile are folded inwards and also connected to the cleaning textile by means of a seam 51.

The mop cover according to the invention is used in particular for the wet, mechanical cleaning of floors without the use of chemical cleaning agents. For this purpose, the mop cover can be clamped onto a known clamping frame. Also of importance is the quality of the cleaning covering, which preferably has twisted threads, which in turn are formed from microfibers. The microfibers preferably have a thickness of up to 5 dtex, preferably up to max. 1 dtex and very particularly preferably up to max. 0.5 dtex. The cleaning threads, which are preferably made of polyester microfibers, have a high capillary effect, so that the mop cover can absorb a lot of liquid.

The cleaning topping can be of different qualities for different

Surfaces (clinker, wooden, stone floors, slab floors, etc.). To this The purpose can be the fiber length, fiber diameter, fiber material (polyester, polyamide, viscose etc.), fiber density (number of fibers twisted together), surface structuring of the fibers and fill density. In order to familiarize yourself with the cleaning surfaces used for cleaning different surfaces, these can be colored differently. It is also conceivable to single-mark the pockets or edges with certain colors.

The mop cover material preferably has a cleaning surface consisting of polyester microfibers, 800 to about 2500, preferably 1000 to 2000 microfibers being twisted into a thread. The microfibers themselves are max. 5 dtex, preferably max. 1 dtex. Such threads have a good one

Capillary action, so that the water absorption or. Water discharge capacity of such a mop cover having such threads is particularly good.
