Definitions

• the present invention relates to a method for cleaning hard surfaces, especially in clean rooms.
• clean rooms are to be understood as rooms or parts of rooms in which an extremely low level of heterogeneous air pollution, such as dust and germs, is to be present in the long term.
• Rooms of this type are increasingly used today in medicine, for example as operating rooms, and in technology, for example for the production of pharmaceutical preparations or microelectronic components.
• the extensive absence of dust, germs and other particles is achieved in these rooms by ventilation with only highly purified air.
• the personnel working in these rooms are subject to strict hygiene requirements and must enter the rooms through special locks. Special standards are also set for furnishings, work materials and raw materials, such as dust content and abrasion resistance.
• the invention relates to a method for cleaning hard surfaces, in particular in clean rooms, in which these surfaces are wiped using a cleaning liquid which consists exclusively of volatile components with the aid of a textile structure which consists of polypropylene continuous fiber fabric.
• This method is used particularly effectively on floors when the textile structure is in the form of a Mop cover is used together with a suitable mop holder.
• the new process allows extremely effective removal of particulate contaminants and also oily and other adhesive contaminants from the solid surfaces. Tissue abrasion (fluff) practically does not occur; Residues from the liquid cleaning agent are not to be feared.
• the cleaning agent used in the process according to the invention is a liquid which consists exclusively of volatile components. Components that evaporate completely from a thin layer at room temperature within minutes to a few hours are considered volatile. These primarily include substances that have boiling points below 100 ° C, in particular boiling points in the range between 60 ° C and 100 ° C, at normal pressure.
• organic solvents should be mentioned primarily, of which in turn the water-miscible organic solvents are particularly preferred. Flammable organic solvents are normally not used alone but only in a mixture with water, the proportion of water in this mixture generally predominating. In many cases the proportion of the organic solvent is not more than 15% by weight of the cleaning liquid, preferably it is between 1 and 10% by weight.
• a cleaning liquid which consists predominantly to completely of a mixture of fully demineralized water and monohydric alcohols having 2 to 4 carbon atoms is particularly preferred.
• the cleaning liquid can contain other volatile additives, for example to increase the disinfectant effect or to increase the Cleaning power included. Examples of such additives are formaldehyde, ammonia and mixtures thereof.
• the textile structure which is used in the process according to the invention to distribute the cleaning liquid on the surfaces and to wipe the surfaces therewith is a fabric which was produced from polypropylene continuous fibers, so-called filament yarns, or is shaped products, which were made from such fabric.
• fabric made of polypropylene continuous fiber combines in an extraordinary way high cleaning effect with almost complete lint-free. This applies particularly to polypropylene fabrics that were made from continuous fibers with an average fiber diameter of dtex 450 to 1,100. Fabrics with an average weight per unit area of 150 to 350 g / m 2 and structures made of such fabric are also particularly suitable.
• the cleaning liquid is applied in an amount which depends primarily on the size of the surface to be treated but also on the nature thereof, to the surface or the textile structure made of polypropylene continuous fiber and then with the textile structure on the surface Distributed surface.
• the distribution of the cleaning liquid and the cleaning of the surface are achieved more or less simultaneously during the wiping on this surface.
• the amount of cleaning fluid is between about 8 ml and 10 ml / m2. In the case of rough or porous surfaces, more cleaning liquid up to about 14 ml / m2 may be necessary, while in the case of particularly liquid-repellent surfaces, significantly smaller amounts of cleaning liquid may also be sufficient.
• the service life of the textile cleaning structure that the The method according to the invention which picks up dust particles, germs and other impurities naturally depends on the degree of soiling of the surfaces.
• the textile structure is not rinsed or otherwise cleaned during use, but is optionally freed of the absorbed liquid by squeezing or wringing and replaced by a new textile structure after sufficient dirt absorption.
• the surfaces can be wiped easily by hand, and simple cloths or, for example, glove-shaped structures can be used as textile structures.
• the duration of the wiping treatment depends on the degree of soiling and is in most cases between about 3 seconds and 10 seconds per m2.
• a holder in the form of a mop-like device. Suitable holders have been described several times for conventional floor cleaning, for example in German patent application 34 32 685 and in German utility model G 84 09 860.
• colders are preferably used which have an elastic, abrasion-resistant coating on their underside, for example made of closed-cell foam rubber .
• the holders are generally designed in a foldable form, as is also described in the patent application cited above.
• the disclosure of this patent application is expressly made to disclose the present application to the extent mentioned.
• the textile structures suitable for alternating operation together with the holders mentioned have flat shapes and have two pockets on their surface for receiving the holder ends.
• Mop covers of this shape which are made of polypropylene continuous fiber fabric, form a further subject of the invention. If necessary, these covers can have further elements which are intended for fastening to the holder and are made of abrasion-resistant material. Examples of the form of such references can be found in German patent applications 32 46 161 and 39 37 717, the disclosure of which is also made with the disclosure of the present application.
