Description

Absorbent structure for cleaning surfaces

The invention is directed to an absorbent structure for cleaning surfaces, which has areas or sections or mixtures of different materials which are either primarily absorbent or primarily cleaning-active in their action, the structure having a carrier structure with cleaning-active material attached thereon.

Cleaning textiles or structures as well as mop covers consist predominantly of cotton and synthetic fibers. Mostly there are mixtures of both basic components. This is necessary because some types of textile have opposite properties and a mop cover only enables maximum performance if many positive properties are combined in it. The water suction power of cotton is approx. 250%, that of synthetic fibers practically 0%. The dirt-bearing capacity of cotton is good, while that of plastic fibers, with the exception of micro or polypropylene fibers, is poor. The abrasiveness of cotton is very low, while that of synthetic fibers is high. Cotton, polyester and polypropylene are washable up to 95 ° C, but the washing stability of cotton is poor, while that of polyester and polypropylene is good. Cotton has a strong shrinkage, while plastic fibers hardly shrink. The sliding behavior of cotton is poor, while that of plastic fibers is good.

Cleaning water serves as a means of transport for the loosened and dispersed dirt. In practice, limits are shown here, since cotton absorbs only 250% of its own weight in water and, moreover, a pure cotton fabric is very unfavorable because of its poor sliding behavior and its instability when washing. With blends of cotton and plastics, properties such as abrasiveness, shrinkage, sliding behavior and washing bility can be adapted to many needs by appropriate selection of the material proportions, however, the water suction is in any case when using different mixed materials less than 250%.

DE 38 09 279 C1 discloses a flat mop cover for maintaining hard floor surfaces, consisting of a carrier fabric, on which material sections are sewn on the underside and on the upper ends of which the holder pockets are sewn on. This describes a damp mop cover for floor care, which consists of a preferably textile carrier fabric with holder insert pockets sewn on top on the longitudinal ends and with material attached on the underside to absorb dirt and moisture. It has a low weight, good absorbency and a large water storage capacity. The underside material in the form of sponge or non-woven cloth material with a high liquid absorption capacity is attached in the form of several strips arranged in a row next to one another, the strips being fastened in regions to the carrier fabric by sewing on. The water absorption capacity of the material made of sponge or fleece cloth arranged side by side is up to 3,600 g / m3, whereby the water absorption capacity is determined according to DIN 53 923 and the relative water absorption of the sponge or fleece cloth material is up to 1,400%.

The flat mop cover according to DE 38 09 279 C1 can, however, still be improved. Because the strips of sponge or fleece material are sewn to the backing material, the reversible drying shrinkage of 30% compared to the wet state leads to considerable problems in the handling of the flat mop covers. When wet, the covers show the calculated length dimension, the cover sheet made of carrier material being flat. When dry, the sponge cloth lamella shrinks by approx. 30% compared to the cotton / polyester cover sheet, which leads to extreme warping. Wipers can therefore no longer be easily inserted into the covers the. If the wipers are still forced into the holder insert pockets, this will result in damage. If the covers are first moistened before being attached to the wiping devices, the wiping devices can be inserted, but this is associated with considerable time and handling. Another disadvantage is that sewing the material around the seams significantly reduces the water absorption capacity of the material.

An improvement in the water absorption capacity or the water suction power has been achieved, for example, in the above-mentioned patent DE 38 09 279 C1 by using a sponge or nonwoven cloth material with a high viscose content in addition to cotton and plastic. Other water-absorbing materials, such as sponge or wood, act by filling the voids in the dry state with air and displacing the air from the voids when the materials are immersed in liquid. However, this liquid absorption requires the material to be immersed in the liquid. This complicates the absorption of cleaning liquor from hard floor surfaces. Even with a residual amount of 15 g of cleaning liquor per square meter, which is unacceptable wetness for coated PVC floors, for example, the thickness of the moisture film on the floor is only a fraction of a millimeter, and the material can hardly be immersed in the liquid to any significant extent.

A different form of water absorption capacity, which can be described by the water absorbency, is therefore required for a mop cover that holds the cleaning liquor. Here, the material fetches the liquid via the suction effect at the contact interfaces, so that the liquid is literally absorbed. While a remainder of 15 g of cleaning liquor per square meter on hard floor surfaces is unacceptable wetness, one is

2 aim for a remaining liquor quantity of 10 g / m. It has been observed that at

2 a residual moisture of 11 g / m the cleaning performance drops suddenly. This negative jump is explained by the free mobility of the pigment dirt in the relatively higher moisture film on the wiping surface. Under

2

11 g / m this option is switched off. The dirt can no longer avoid the wiping materials, but rather adheres to the material on the active cleaning side during the wiping movements and can be removed in this way.

The invention is therefore based on the object of providing a solution which opens up expanded variations and variabilities in the case of an absorbent structure for cleaning surfaces with regard to its design options with regard to its cleaning-active and absorbent properties and / or effects.

In the case of an absorbent structure of the type mentioned at the outset, this object is achieved according to the invention in that the structure has a pocket-shaped or bag-shaped cavity with snippets or strips of highly absorbent material arranged therein.

The invention creates the possibility of arranging the primarily absorbent material with highly absorbent properties on the absorbent structure at a different location and regardless of the areas or sections with primarily cleaning-active material. The highly absorbent material is preferably and in particular formed and arranged on the opposite side of the active cleaning surface of the primary active cleaning material. Since the necessary water absorption function, that is to say the water suction and water storage function is now essentially separated from the cleaning-active material, the cleaning-active material can be designed specifically for its cleaning-promoting effect, the water absorption effect or absorption capacity of the material being neglected. Overall, the cleaning structure according to the invention has a very high liquid absorption capacity as a result of the snippets or strips, in particular loosely arranged within the closed cavity. The properties of the cleaning textiles such as abrasiveness, dirt-bearing capacity, sliding behavior, etc. are determined by the properties of the material, which primarily acts as a cleaning agent. In this way, the positive properties of both the cavity content, namely the highly absorbent snippets, and the outer material, including the carrier structure, are combined and optimized without their respective properties having a negative influence on one another.

In an embodiment, the invention provides that the snippets or strips are arranged loosely in the cavity, the cavity being closed on all sides in a development of the invention.

A particularly preferred application of the absorbent structure is the configuration as a flat mop cover for the maintenance of hard floor surfaces.

In the known flat mop cover mentioned above, the technical problem is in particular to include highly absorbent materials in the construction of mop covers from material mixtures in a form which avoids the disadvantages of the different shrinkage behavior and from the impairment of the water absorption capacity in the seam area.

To solve this problem, the invention therefore provides in further development that the absorbent structure is designed as a flat mop cover for the care of hard floor surfaces, consisting of a support structure on the underside of material sections made of cleaning-active and / or absorbent material or material combinations and on the top on the The longitudinal end of the holder insert pockets are sewn on, so that the carrier structure is absorbent or water-permeable and that a cover sheet is attached to the top of the carrier structure. is sewn, a cavity being formed between the support structure and the cover sheet, which is filled with snippets or strips of highly absorbent material loosely arranged on the support structure.

Such a flat mop cover has the advantage that, overall, it has a very high liquid absorption capacity, to which the material sections attached on the underside of the carrier fabric, the carrier fabric and most of all the snippets loosely arranged on the carrier fabric contribute. The flat mop cover is therefore suitable for wiping wet hard floor surfaces as well as for applying cleaning liquor to hard floor surfaces. The liquid is transported between the individual reference parts via the absorbent material parts.

For example, when wiping wet surfaces, the liquid is first sucked up by the surface from the material sections on the underside and passed on to the carrier fabric and from there to the snippets arranged thereon.

Before the washing liquor is applied to the floor to be cleaned, the mop cover is immersed in a container with the cleaning liquor so that the absorbent parts of the cover soak up the washing liquor. When attaching the flat mop cover using the mopping device, the material sections on the underside first come into contact with the floor. As soon as these and subsequently the carrier tissue have released the liquid stored in them, a short pressure on the snippets is then sufficient to squeeze out the liquid stored in them and dispense them onto the surface to be cleaned via the carrier tissue and the material sections on the underside.

Due to the very large liquid reservoir in the chips or strips, it is also possible to partially cover the underside material sections with non-absorbent materials, e.g. B. plastic fibers, at least partially to replace, to improve other properties that are important for cleaning performance, such as abrasiveness and or sliding behavior, but also shrink and wash stability of the material mixture, since the absorbency and liquid transportability are due to the cotton content in the mixture, and the water storage capacity is primarily due to the highly absorbent material available Snippets or stripes are perceived.

The fact that the snippets of highly absorbent material, which have a different shrinking behavior to the other materials, are only loosely arranged on the carrier fabric or in the pocket formed by this and the cover sheet arranged above it, the reversible shrinkage of this material acts between the wet - and dry conditions do not affect the shape of the covers.

The cleaning-active material or the material sections of this type preferably have the form of fringes, loops, shags or lamellae. It is also preferred that it or they are arranged distributed over the entire underside surface of the carrier fabric.

It is also proposed that the cleaning-active material or the material sections of this type consist of plastic, in particular polyester, or microfibers or cotton or a mixture of these substances. The choice of materials depends on the desired cleaning properties.

It is also particularly advantageous if the flat mop cover has a circumferential bead, which in particular consists of the same material as the material sections attached to the carrier fabric. Particular advantages result when the bead in the form of a seam is sewn to the flat mop cover in such a way that the edge of the longitudinal strip (s) projecting into the center of the underside of the cover lies loosely on this underside. This results in two different effects depending on the wiping direction. The Longitudinal strips of the bead lying at the front lie flat between the underside and the wiping surface. The opposite longitudinal stripe of the bead, on the other hand, stands up and in this way forms a scraper that increases the cleaning performance again.

In a further important advantageous embodiment, the cavity has several, in particular two to five, chambers for the snippets or strips. The subdivision of the mop cover into several chambers enables a more even distribution of the snippets even when the cover is used differently. Without this subdivision, it could happen that the snippets or strips slip, for example in the case of a mop cover, onto one end of the generally elongated flat mop cover, so that the other end would be free of snippets. It is also advantageous if these chambers are divided in the longitudinal direction. Such a division does not impair the cleaning performance. If the pockets were divided transversely, the corresponding seams would cause depressions on the active cleaning side of a mop, so that contact between the mop cover and the surface to be wiped would be prevented and the wiped surface would have a streaky appearance.

It is also proposed for a flat mop cover that the holder insert pockets are stretchable. In this way, the mop cover can be used both for hinged holders and for rigid holders. In the latter case it is necessary that the holder insertion pockets are stretchable.

However, the invention not only relates to flat mop covers. In another particularly advantageous embodiment, the absorbent structure for cleaning surfaces can also be provided for manual use, that is to say without the use of wiping devices. For this purpose, it is proposed that the absorbent structure for cleaning surfaces is designed as a bag and that the carrier structure has bristles on its outside, in particular synthetic materials. bristles, as a cleaning active material. This bag is able to absorb a large amount of water on the one hand and to hold and dispense it on the surface to be wiped on the other. At the same time, the outside with bristles ensures a good cleaning effect. The bristle trim creates the necessary abrasiveness. With the bristle ends, dirt particles are removed from the smallest recesses. Such an absorbent structure, which has a bag-shaped cavity, can easily be produced as a sponge substitute in a size suitable for gripping with one hand.

Both in the case of the sponge bag and in the case of the flat mop cover, it is also advantageous if the snippets or strips of highly absorbent material absorb 250 to 1,500% of their own weight in liquid.

It is also advantageous if the highly absorbent material consists at least predominantly of viscose, which the invention further provides.

Finally, the invention provides an embodiment of a system comprising an absorbent structure with the features according to one of claims 4 to 10 or 12, 13 and a wiper device with a handle and a wiper plate connected or connectable to the handle via a preferably cardan joint for holding the absorbent structure on an underside of the wiper plate and from a pressing device for the wiper device, the pressing device having a support surface provided with openings and a counter-bearing device arranged at a distance therefrom, so that the wiper plate between the bearing surface and the counter-bearing device with a downward insertion movement is insertable and can be pressed against the bearing surface by tilting with support on the counter bearing device with its underside holding the absorbent structure. Such a wiping device and such a squeezing device, which interact in the manner described, are known from WO-A-98/06316 and GB-C-330 543 and the German patent application 100 13 044 by the applicant. In this respect, express reference is made to the disclosure content of these writings.

In all drawings, the same parts have the same reference numerals and may not be mentioned separately for each drawing.

Experiments have shown that viscose absorbs 15 times its own weight in liquid without mechanical action from the outside, such as compression and expansion. These measurements were carried out in accordance with DIN 53 923 and, in addition to this relative liquid absorption, showed network Times of less than 4 seconds and a suction speed of more than 5 cm / s. Depending on the proportion of viscose in material blends with cotton, the liquid absorption capacity of the mixture is 2.5 to 15 times its own weight, corresponding to 250 to 1,500%. Scraps or strips of such a highly absorbent material are used as the highly absorbent material in the exemplary embodiments of the invention described below.

FIG. 1 shows an absorbent structure for cleaning surfaces in the form of a flat mop cover, viewed obliquely from above. In the case of the flat mop cover, a cover sheet 5 is sewn all around at the edges of a support structure 6 formed as a woven or knitted fabric, referred to as support fabric for the flat mop cover. On the underside, material sections of primarily cleaning-active, ie. H. an abrasive, abrasive and / or dirt-absorbing effect, material attached, which have the shape of fringes in the illustrated embodiment. These material sections also have a certain absorbency. At the longitudinal ends 5 holder insertion pockets 2 are sewn onto the cover sheet. In Figure 1, a section 4 of the cover sheet 5 is shown, so that in the opening it is possible to view snippets 1 loosely arranged on the support structure. These snippets 1 lie on the carrier structure 6 in a pocket-shaped cavity formed by the sewn-on cover sheet 5 and the carrier structure 6.

The ends of a folding holder can be inserted into the sewn-on holder insertion pockets 2 for fastening. With the spread folding holder, a flat pressure can easily be exerted on the cover sheet 5 and thus on the highly absorbent snippets 1 arranged underneath it, in order to fully or partially express a quantity of liquid stored in the material, depending on the amount of pressure exerted. Likewise, before using the flat mop cover for dry wiping with appropriate pressure the stored liquid is squeezed out of the flat mop cover so that the flat mop cover has the full suction capacity for wiping.

Figures 6a and 6b show a schematic sectional view of a suitable pressing device 29, in Fig. 6a when inserting the wiper plate 24 and in Fig. 6b when pressing out the flat mop cover 25. Fig. 6a illustrates the insertion movement 34 with which the wiper device or its Wiper plate 24 with a longitudinal edge 22 is inserted into the pressing device 29 between the bearing surface 31 provided with openings and the counter bearing device 33 or its counter bearing elements 33. As a result, the holding sections 28 assigned or adjacent to the introduced longitudinal edge 22 are brought into engagement with the counter-bearing device 33 or their counter-bearing elements 33, or an engagement in this regard is made possible, so that securing sections 35 of the counter-bearing device or the counter-bearing elements projecting or projecting towards the bearing surface 31 33 reach behind the inserted holding sections 28 or their undercuts or can reach behind them.

The extent to which the insertion movement 34 must include swiveling or tilting of the wiper plate 24 about its longitudinal axis depends on the clear distance A between the securing sections 35 and the bearing surface 31 in relation to the overall height of the wiper plate 24 with the wiper textile 25 and the holding sections 28 projecting highest on the top from. A pivoting-in, as indicated in FIG. 6 a, is preferably necessary so that the wiper plate 24 is positively secured against being moved out of the pressing device 29 when the wiper plate 24 with the wiper textile 25 rests on the support surface 31 over the entire surface, as in FIG. 6 b shown.

6a and 6b that the squeezing device 29 shown in the state of use is designed such that the bearing surface 31st is inclined by an angle β relative to the horizontal 37. The angle of inclination is preferably between 30 ° and 60 °, in particular approximately 45 °. In combination with the counter bearing device arranged in the lower region - here in the region of the lower longitudinal edge 36 - this results in simple insertion and pressing out of the wiper device.

6b illustrates the squeezing. When the wiper plate 24 is inserted, the handle 32 is folded or pivoted about the longitudinal axis away from the counter-bearing device according to arrow 38. The stem 32 or part of the joint comes to rest on the wiper plate 24 - here, for example, in the area of the V-shaped recess 18 - so that a further pressing on the stem 32 in the direction of arrow 38 also depresses the wiper plate 24 has its underside to the bearing surface 31 result, whereby the flat mop cover 25 is pressed out. The counter-bearing device or its securing sections 35 interact with the inserted holding sections 28 of the wiper plate 24, in particular in a hinge-like manner, the counter-bearing device virtually forming the pivot point for a one-armed lever formed from the wiper plate 24 and the subsequent handle 32. This one-armed lever enables the flat mop cover 25 to be simply pressed out on the articulated wiper device.

The liquid is transported both during liquid absorption and during liquid dispensing via the adjacent absorbent parts of the flat mop cover, namely from the underside material sections made of primarily cleaning-active material via the absorbent or at least water-permeable carrier structure to the snippets 1 and / or strips arranged thereon and vice versa. It is not necessary for the material of the holder insertion pockets 2 and of the cover sheet 5 to be absorbent and to have a liquid absorption capacity. In Figure 1, only the fringed material sections 3 arranged along the edge can be seen. The material sections can also be in the form of loops, shags or lamellae and are generally distributed over the entire underside surface of the support structure 6. The material sections on the underside can be arranged in a straight line next to one another or in circular or zigzag paths alongside one another.

Since the liquid absorption capacity of the underside, primarily cleaning-active material sections only make up a relatively small proportion of the liquid absorption capacity of the entire flat mop cover, while the snippets or strips arranged loosely in the pocket make up a very high proportion or the essential proportion of the liquid absorption capacity of the absorbent materials in these underside material sections in favor of the fiber components that positively influence other required properties such as abrasiveness and lubricity.

Figure 2 shows a plan view of the top of a particularly preferred embodiment of a flat mop cover according to the invention. The highly absorbent snippets 1, which are not visible in this figure, are arranged in two longitudinally extending chambers 7a, 7b, which are delimited at the top by the cover sheet 5 and at the bottom by the carrier structure 6 (FIG. 3). Both chambers 7a and 7b are divided by a continuous longitudinal seam 8. This longitudinal seam also runs below the holder insertion pockets 2, which are elastic in the present case.

The support structure 6 on the underside of the compartment wipe cover (FIG. 3) here consists of a microfiber velor with a pole height of 2 to 10 mm. The term "pole height" refers to the length of the outwardly projecting loops or fringes. A circumferential bead is made of the same material and is formed by two longitudinal strips 9 and two transverse strips 10. The transverse strips 10 are sewn at their outer edges to the cover sheet 5 or the support structure 6. This is indicated by the seams 11 passing through the flat mop cover. In contrast, the two longitudinal strips 9 are sewn to the cover sheet 5 only on the upper side of the flat mop cover in the region of their edges. The corresponding longitudinal seams have the reference number 12. On the other hand, the longitudinal strips 9 are significantly wider and the longitudinal seams 12, which, like the transverse seams 11, pass through the entire flat mop cover, are closer to the edge of the flat mop cover than at the edges of the longitudinal strip 9, so that a relatively wide portion 13 protrudes unmachined on both long sides of the cover in the middle of the cover.

When wiping transversely to the longitudinal direction of the cover, the two longitudinal strips 9 behave differently. The longitudinal strip lying at the front lies flat between the carrier fabric 6 and the wiping surface. The longitudinal strip 9 lying further back, however, straightens up with its unmown edge up to the seam 12 and in this way forms a stripper which absorbs liquid and dirt and in this way increases the cleaning performance.

It should also be pointed out that in the present exemplary embodiment the cover sheet 5 and the carrier structure 6 are made of different materials. The cover sheet 5 consists of a solid woven textile. However, it is also possible that only microfiber velor or another cleaning-active textile is used both for the cover sheet 5 and for the carrier structure 6.

Another exemplary embodiment of the invention is shown schematically in FIGS. Here, the absorbent structure for cleaning surfaces consists of a filled bags. This embodiment is intended to advantageously replace a conventional sponge.

Usual, known sponges do not suck water, e.g. B. as a result of capillary action. The foamed body of conventional sponges has many open pores, and when the sponge is immersed, water runs into these cavities. This process can be accelerated if the sponge is dipped under water in the compressed state and expanded there. Also known are sponges that are laminated on one side with a pad. The actual sponge body serves as a handle for handling such an abrasive abrasion pad. However, wet surfaces cannot be dried with such sponges.

In contrast to this, the bag according to the invention is not only suitable for cleaning surfaces, but also for wiping dry as a result of its highly absorbent snippets or strips as the primary absorbent material.

The outer shell of the bag 14 in FIG. 4, which surrounds the snippet-containing cavity on all sides, is formed by the carrier structure 6, which is permeable to water and has a close-knit bristle trim 15, 16. The bristles 15, which are arranged in rows 16 on the carrier fabric 6, bring about the desired abrasiveness, that is to say they are primarily active in cleaning. Such a row of bristles 16 is shown enlarged in FIG. With the bristle ends, dirt can be removed from the smallest recesses. The bristles can also have a certain absorbency.

The bristles are preferably 1 to 10 mm long and are made of plastic, so that the fittings are protected in the sanitary area and are not scratched. The bag 14 is filled with the highly absorbent snippets of sponge material already discussed above as the primary absorbent material, which can preferably absorb up to 1500% of its own weight in water. The bag according to the invention is therefore particularly well suited for drying wet surfaces, since the snippet-like or strip-like material readily absorbs the water to be removed.

The individual materials or material sections of the absorbent structure can be designed as textiles, woven fabrics or knitted fabrics.

In the context of the above disclosure, absorbent and absorbent also mean water-absorbent or water-absorbent or water-absorbent or water-absorbent, so that these terms are used synonymously in this respect.

A particularly suitable material for the highly absorbent snippets / strips are pieces sold by the company Kalle / Nalo, which are produced in the manufacture of sponge cloths as waste pieces from the edge area thereof, 2/3 made of viscose and 1/3 made of cotton fibers, preferably for shape stabilization , consist.
