A complete list of the above compounds and claims in previous patents (No. 200400749(4) and 200402048(2)) disclose the full interval and antibacterial, antiviral, algaecide and fungicide activity. The vast majority of the above compounds have many uses, in addition to the applications mentioned above have a total antibacterial activity, which also eliminates gram-positive and gram-negative bacteria, viruses, algae and fungi.

The level of technology

Earlier attempts were made to access the filters against Legionella, but when testing in practice they proved ineffective. Such filters made of porous material for f is litraly bacteria larger than 0.2 μm (Legionella bacteria are very small, of 0.3-0.9 μm in width and 2 μm in length).

Patent GB No. 846458 refers to the air filter, for example, for installations for air conditioning, which is chemically treats the air to prevent the spread of bacteria and fungi. The filter is preferably made of fiber, which may be of any type, treated with bactericides or fungicides. The filter described in this patent includes antibacterial materials on the surface of the filter, as they are ineffective inside the filter and cannot be used in water. This patent does not include bactericidal activity against Legionella.

In U.S. patent No. 2178614 describes the filter of fibrous material, which can be treated with antibacterial substances. Such material may be a glass fiber, natural fibers, and other fibers. This fiber does not work in water and also has a surface subjected to antibacterial treatment, which is resistant to washing. This patent does not include bactericidal activity against Legionella.

U.S. patent No. 2003098276 relates to a filter for liquids to remove particles and bacteria. The filter contains fibrous material, such as metal fibers, which, when coming into contact with the liquid containing bacterial product, show bactericidal action. This filter is Ozden for filtering liquids from the machines. He was too heavy and does not have small holes. The filter is not applied to air and, therefore, does not remove bacteria, keeping them. It only reduces the number of bacteria and only some colonies, including Legionella is not included.

In addition, none of these documents makes no reference to the treatment against Legionella, and no mention of the filter leaves or injected structures.

In addition, the invention includes a method of obtaining filters using non-woven filters or leaves or injected filter structures.

The basic premise of the invention are non-woven materials with antibacterial additives intended for various applications, such as, for example, the use of nonwoven materials for processing bacteria that causes the odor Shoe lining.

Other assumptions of the invention are a mixture of fibers treated natural fibers for non-woven anti-bacterial protection material for mattresses, upholstered furniture, curtains and wall and floor fabric coverings, resulting in increased comfort for the user, particularly for people with allergies and asthma, with the added advantage of a non-woven material that can be washed at temperatures up to 90°and some to 95°

One of the advantages achieved by the processing of the fibers instead of handling non-woven materials, has become a high resistance in the case of antibiotic treatment, as it remains much longer in the application process the fibers. The treated fibers retain their antibacterial treatment in the tissue, as it is not a surface treatment, in contrast to the processing of non-woven material.

The experiment showed that in addition to various legal measures are the most effective means of preventing Legionella is disinfection and periodic cleaning of the installations at risk. In order to implement such measures, should be permitted disinfectants, for example, is effective, hyperchloraemia cooling towers, but it gives only temporary effect, and the problem generally occurs again within months, sometimes days, after disinfection. Hyperchloraemia also inefficient in pipes and pipelines, as well as in the heated areas of the installation.

In collaboration with the manufacturers of antibacterially chemical products and fibers were made of nonwoven materials with fibers that have already been processed during extrusion (in weight)that meet the purposes of the invention. This means that the nonwoven material has an improved wear resistance.

Previous experiments the deposits showed for the purposes of this invention the perfect fibers in the nonwoven materials of the invention can be polypropylene, polyester, acrylic, polyamide, modacryl, rayon, polyethylene, aramid, bicomponent fibers, etc., i.e. fibers from a mixture of two or more of the above fibers, and other fibrous materials according to the requirements of the application.

Fiber listed in the paragraph above, allow bacterial treatment, which penetrates all the fiber (due to the inclusion of bactericide during extrusion). Therefore, it can be argued that antibiotic treatment is not a surface treatment of the fibers or nonwoven material, as it was previously.

The range of possible fibres in non-woven material allows for great variety in thickness, and type of cross section, which may be round, square, elliptical, hollow and of a different type, which showed equal efficacy for non-woven material used in this invention for filtering.

Manufacturer of filter allows you to combine it with any other fiber properties, other than already defined, without the need to include them all in the processing.

The filter allows you to remove Legionella, detained on the filter, neutralizing the proliferation of bacteria in jekotektura. It also removes bacteria from the space surrounding the filter. Also the processing of the fibers during extrusion prevents leaching and oxidation of biocide incorporated during extrusion, and the corrosive influence of water treatment.

Samples of nonwoven materials 500 and 1000 g/m2obtained according to any method of the present invention, is subjected to the tests in the Microbiology laboratory in order to evaluate their behavior in relation to Legionella pneumophila, the subspecies pneumophila, ATCC 33152.

During such tests with Legionella use of bacteriological agar GVPC and physiological NaCl (common salt). Cultures get with these substances and suspensions with an initial concentration of about 106Legionella/ml

Get three different solution, which is subjected to incubation for 7 days at 36°With concentrations

- 7,1×106Legionella/ml solution

- 7,1×104Legionella/ml solution

- 7,1×102Legionella/ml solution.

Preparing for the tests finish, pouring the resulting solution into cups for analysis, to which was added 100 ml of agar (1%). The concentration of Legionella in agars for tests comprise the

- 7,1×105Legionella/ml solution

- 7,1×104Legionella/ml solution

- 7,1×103Legionella/ml solution.

At the same time prepare other cups for analysis with the similar solutions at three concentrations for in order to add the analyzed samples of nonwoven filter materials. In the test of 72 hours is incubation at 36°C.

This test originally designed to verify the absence of growth or proliferation of bacteria in the presence of cellular bacteria Legionella.

Reducing the presence of bacteria occurs not only when tested on the samples with high concentration of Legionella (7,1×105) in the original sample, but also in those cups for trials where the initial concentration of bacterial composition is less than 1000 times.

Consequently, the results of microbiological analysis of non-woven material according to the invention prove not only the inhibition of growth and proliferation of bacteria, but also its distinct bactericidal action.

The obtained non-woven materials with the properties described above, is mixed with other non-woven materials so that you get the multilayer non-woven material against Legionella based non-woven fabric and polypropylene, polyethylene, polyester, fiberglass, steel, aluminum components, foams, etc. as the basis for a product according to the invention. This facilitates its use for the implementation of the tanks, settling tanks, cooling towers, heat exchangers, fans and any other place where it is possible to reduce the concentration of Legionella by filtration the purpose of their statistical deposition.

In the first paragraph of the claims in this application specifies the mode of production, which will be used artificial fibers, chopped or continuous strands of synthetic fibers and their mixtures, pre-treated antibacterial compounds, which are defined in paragraph 17 of the claims, in which the antibacterial treatment of fibers is performed on the basis of derivatives of silver, phenoxyacetamide derivative vector of the chain, with the addition of derivatives of permethrin, derivatives isothiazolinone, tetraalkylammonium, tsinkorganicheskih compounds, phosphates of zirconium, sodium, triazine, oxazolidines, isothiazolines, vermiformis, resides, isocyanates, chlorine derivatives, formaldehyde, carbendazim or crumbs or mixes crumbs treated similar products.

During the development of products according to the invention carried out various tests according to the procedure described in the invention, changes in some aspects without changing its essence.

This product is characterized by the fact that he has a biocidal and biostatical action.

Such experiments lead to the conclusion that the application by physico-chemical methods of antibacterial compounds directly on the non-woven material instead of the original hair is to also give the desired bactericidal effect, and this method is also effective against Legionella pneumophila.

Another option is getting felt from the treated fibers and post-processing of antibacterial material that is able to gradually release biocidal product.

Some compounds (salts and other derivatives)derived from zinc (Zn), tin (Sn), copper (Cu), gold (Au), silver (Ag), cobalt (Co), Nickel (Ni), palladium (Pd), platinum (Pt), cadmium (Cd), as well as other transition metals and other metals form ions, which upon release have a noticeable antibacterial properties.

During the development of this invention, various compounds of one or more of the above elements were mixed for application with other additives on the basis of the nonwoven fabric for filters or filtering of injected sheets of different ways:

- drawing in the form of microscopic powders

- drawing in the solution, suspension or emulsion of water or any other liquid, if it is technically possible,

- drawing in a mixture with polyethylene, polyimide, crumb EVA, various types of adhesives for hot melt or any other type.

The basic procedure of applying the following:

- in the bath with fluid, mainly water liquid,

- splash

- spraying,

- rolling,

- induction,

<> - dive into any of the above environments

- any other conventional procedure in the field of plastics, of textile materials and foamed materials, technically equivalent to the above and applicable to the invention.

With regard to the application of the above methods, it is necessary to indicate that the processes are limited to 300°because if the temperature is above a specific connection can change and lose their bactericidal properties.

Also, another direction in the development of the invention are fibers. In addition to the fibers described in this application, use other biodegradable fibers. Combining the percentage of fiber and bactericidal(s) of product(s)described in the application, you can obtain fiber, releasing the exact percentage of bactericide specified in the application.

The same properties as that of copper and its derivatives, in the sense of being able to release positive and negative ions by ionization of the zinc and other metal from among metals listed above). Such products can be considered as technical equivalents.

Test the product according to the invention make it possible to observe the effect of creating space, near which Legionella no longer exists. This allows you to use the products according to the invention as strong bactericides, forming bi the film, eliminates bacteria, creating a sterile space. Such products when they are applied can float on the surface of a section of gas-liquid.

Further research showed that Legionella can be transmitted by inhalation or swallowing. Such inhalation or swallowing can give water infected with Legionella, easy access to and reproduction of Legionella in them. This type of infection is selected from information about Legionella in the "Society of Health Care Epidemiology of America and other medical publications. This possibility of infection are common for all species of Legionella, and not only for varieties pneumophilla.

Taking into account the above it is shown that Legionella pneumophilla found in mass sources, systems supply drinking water to homes and other places, can be a source of infection in addition to the traditional systems, described in the main application.

Other studies explain that infection with Legionella can be found in pipes, water circulation systems in food packaging, industrial bottling water and beverages in the food industry in General, in certain cases, and if such infected drinks, water and liquids behave directly to the person, while in the gastrointestinal tract, do not give consequences from the point of view of health and therefore are not contagious. However, if such history is Nicky swallowing transferred, even in microscopic amounts, from the mouth and gastrointestinal tract, the respiratory tract, infection can occur. With this in mind you should always have in mind that in installations of equipment can accumulate water and/or highlight it in the form of an aerosol.

In the above information, which mainly consist of scientific reports, messages, medical centers and research institutions of an infectious disease, it is assumed that the risk of infection from Legionella pneumophilla exists in the above installations, as well as in drinking water installations and equipment that become dangerous, dirty water, as, for example, in storage systems and water distribution systems in buildings, airports, trains, ships, and other such places.

As a consequence of the above, and as one of the goals of these improvements is the use of the filter according to this invention in combination with other filtering methods that can be used in the above-mentioned public sources, systems of drinking water supply, water circulation systems, in industry generally, drinking water installations and systems of storage and distribution of water in the transport network. As a result, the filter delay Legionella will make the filter structure and will be part of other more complex fil the ditch.

Such complex filters should include the usual filters and filtration systems, such as cartridge filters, rotary vacuum filters, press filters, plate filters, membrane filters, tangential filters, centrifuges, equipment for ultra - and microfiltration, reverse osmosis, dialysis, cyclones, electrostatic filters, and these filters.

In such filters, the fabric filter according to the invention of woven and non-woven material can act as a filter by itself in the presence of other filter elements, for example membranes for microfiltration and ultrafiltration, or as an anti-microbial protective coating and a fat separator, even forming part of the source material for membranes and other filtering elements, and it can be made in the form, for example, plates for membrane filters.

Another improvement is the receipt of the items described above in the non-woven material with the use of monofilaments, as claimed in claim 11 claims.

Another goal of these improvements is the application of methods of obtaining the filter, as claimed in patent No. 200400749(4) and 200402048(2), for items of cleanliness and decoration, such as towels, curtains, sheets, pillows, blankets, carpets, rugs, curtains for showers, bathmats, bandages, rags for wiping the item is and whether other similar products, used for recreational purposes in public buildings such as clinics, sanatoriums, hospitals, laboratories and facilities, and other similar structures.

The method of obtaining, shown in figure 4, begins with the first asprawl the ing and mixing fibers, for example treated polypropylene fiber 2,4-7 denier, mixers (9). The resulting mixture is passed to the loader (10), where fibers accumulate so that they can appropriately apply (11). The carding machine (12) stops the stretching of fibers and directs them to the formation of the sheet. In the transducer of the webs (13) sheets combine to form felt. This felt (8A) is subjected to the first piercing hole punch preliminary hypoproteinemia (14). After the punch prior hypoproteinemia (14) add the second treated polypropylene nonwoven with a two-component fiber 17-30 denier and 50 grams of polyethylene mesh (8b). Three layers of puncture needles in the first puncher hypoproteinemia (15) and then strengthen in the second puncher hypoproteinemia (16), and so on. Polypropylene and bicomponent layer calandro (17), draw up and rolled down (18).

The result of this method is a multilayer material formed of polyethylene mesh and two layers of nonwoven material with different filtering ability.

The method, shown in figure 5, can be performed as follows: starting from the treated polypropylene fibers and bicomponent fibers in the 70-110 denier in the loader (10), the material serves in woollen machine (19), where the image is to be felt, which is then pierced with needles in two stages in the punch prior hypoproteinemia (14) and the puncher hypoproteinemia (15) to obtain the final nonwoven material with high filtration capacity in the calender (17). The material is then rolled down and make out in a cutting machine (33) and prokatchika(18).

The method is shown in figure 6, describes how to obtain a nonwoven fabric with a thickness of 150 mm (8C) of the fiber 70-110 denier, including treated polypropylene and thermoplastic bicomponent fibers during skolachivaniya in the furnace and heat-setting process. The resulting material is impregnated with a foaming agent in management (21) and first subjected to preliminary drying furnace for pre-drying (35) and dried in an oven (22). The material is then rolled down using a corrector (34) and is decorated in a longitudinal cutting machine (33) and prokatchika (18).

Then the obtained non-woven material is passed on line scattering (23). Before entering into the diffuser (23) non-woven material should first be deployed in raskatyvateli (20). In the diffuser in one of the operations the material is sprinkled with powder of polyethylene, which is melted in the electric furnace (22). Micro-perforated filter sheet (8d) is overlaid on the resulting layer, fused with polyethylene, before serving on the calender for cooling and coagulation (24). To the final result is a non-woven material, containing the filter sheet of foam material, which is rolled and decorated in a cutting machine (36) and prokatchika (18).

As can be seen in figure 7, a mixture of polyethylene and polypropylene fibers in 70-150 denier load in the loader (10). The mixture of fibers of two types passed through the first time (38) and then in subsequent loaders (10), which supply woollen machine (19). In woollen machine (19) form the sheet supply air and smoothing. Received a leaky flat sheet lightly puncture needle punch preliminary hypoproteinemia (14) in order to align the felt. Then it moved into the furnace (22), where the polyethylene is melted.
