Definitions
- the present invention relates to a flat mop, in particular disposable flat mop, and the use of the flat mop for clean room cleaning.
- Known flat mops are essentially flat and have an elongated shape. They have on the cover sheet side attachment means for a flat mop holder. Often, terminal pockets attached to a right-sided cover sheet side are used. In general, the reusable mop is moistened by complete or partial immersion in a container filled with liquid. This usually requires the use of a cleaning cart comprising at least two or more receptacles.
- the WO 2009095736 relates to a flat mop, which is covered on a front side with microfibers and has grooves on said front side, which are free of microfibers.
- the grooves are intended to serve as a pick-up area for dirt while the microfibers are the active areas that contact the ground.
- the DE 10 2012 012 4002 relates to a flat mop cover for clean rooms, which has a base without applied threads. The absence of threads makes the particularly good suitability for clean rooms, as fewer particles are released.
- the main body comprises a flat textile material, which may be a knitted fabric, a knitted fabric, a woven fabric or a nonwoven fabric.
- the DE 20 2007 011 580 U1 describes a mop having a cover sheet of resistant synthetic fibers, wherein a wiping surface is provided from microfiber plush.
- the wiping surfaces have freely movable blades at the edges on the underside of the flat mop.
- the DE 10 2012 012 402 describes a flat mop cover for clean rooms, wherein the textile material may be formed as knitted fabric, knit fabric or nonwoven fabric.
- the flat mop cover has a pivotable cleaning lip.
- the cleaning surface has no base fabric with applied threads.
- the DE 101 34 948 also describes a clean room mop system, with the mop showing improved uptake for chemicals, water and oils.
- This thread loops are made of yarn, which are made of ultrafine endless polyester yarn or nylon.
- the cover sheet can be made of a PU-coated Rascheltuch or made of a PVC (polyvinyl chloride) -coated hankerchief.
- a particular challenge in the development of flat mop systems for clean rooms is the degree of cleaning to be achieved combined with a controlled supply of disinfectant and / or cleaning liquids for the purpose of optimum humidification. If the flat mop is not adequately soaked or moistened, there is often no continuous liquid film formed on the surface to be cleaned. There is no complete disinfection or cleaning. On the other hand, if too much liquid is added to the mop when soaking, there is a risk that dirt particles will not be absorbed by or held in the fiber structure of the cleaning surface. In addition, the cleaning layer not only has to take in all microparticles and not re-release, but also to ensure that any dirt particles are removed from the substrate to be cleaned, absorbed in the cleaning layer and not released again.
- the present invention therefore an object of the invention to overcome the above-mentioned disadvantages of the prior art and to provide a flat mop available, which always ensures a high cleaning power in addition to the reliable and controlled humidification in particular of clean room areas. Besides, it is a task, a Flat mop can be provided, which can also be used with conventional flat mop holders and humidification systems.

With such intermediate layers allows a very pronounced area performance of the flat mop invention.
- the topsheet layer is based on a spunbonded material in an expedient embodiment. It has proven to be sufficient for many applications to design the cover sheet single layer.
- Spun nonwovens are well known to those skilled in the art. They are generally obtained from fibers spun from polymer melt passing through nozzles and drawn by cold air and / or mechanically drawn. These fibers are then usually formed directly into a spunbonded or form after solidification of this spunbonded nonwoven.

In particular, residues adhering to the surface to be cleaned can not only be removed with the flat mop according to the invention, but also immediately absorbed by the microfibers.
- FIG. 1 If one takes the representation of a flat mop 1 according to the invention from the front, that is, the front view of the cleaning layer 2, as it is used for the cleaning of surfaces.
- the cleaning layer 2 is in the illustrated embodiment in a rectangular basic shape with the first and second edges 4 and 6, which form the narrow sides of the rectangular basic shape.
- the first and second strip-like areas 8, 10 are in the illustrated embodiment in the form of longitudinal strips and extend from the first edge 4 to the opposite second edge 6. They run essentially parallel to one another and parallel to the opposite edges 12, 14 of the longitudinal sides of the rectangular basic shape of the flat mop 1 according to the invention
- FIG. 1 reproduced preferred embodiment of the flat mop 1 according to the invention adjacent to the edges 12 and 14 of the longitudinal sides of the rectangular basic shape each first strip-shaped areas 8 at.
- the illustrated flat mop according to the invention has at the front five first strip-shaped areas 8 and four second strip-shaped areas 10.
- the first strip-shaped areas 8 use microfiber material, for example warp-knitted or circular-knitted terry cloth or knit made from microfiber material, while for the second strip-shaped areas 10 predominantly or exclusively non-microfiber material, preferably also in the form of warp knitted or circular knitted terry cloth or knitted fabric is used.
- the first and second strip-shaped areas 8, 10 are hereby preferably an integral part of a uniform knitted fabric, fabric or knitted fabric, preferably a component of a uniform terry fabric or knitted fabric obtained by means of circular knitting processes.

- the cover sheet layers face each other and form the engagement openings 24 and 26, respectively.
- the first strip-shaped areas 8 in the form of the strips 30 and the second strip-shaped areas 10 as strips 28 are continued in the area of these engagement pockets 20 and 22.
- the engaging pockets are obtained in the illustrated variant in that one sews the successive coming to rest edge portions of the longitudinal sides 12 and 14 together.
- cover sheet layer 32 and the cleaning layer and optionally the intermediate layer may be connected to each other via spaced seams. These preferably extend from the first edge 4 to the second edge 6 or, if the end portions are folded to form engaging pockets, also in these folded-in areas.
