BACKGROUND OF THE INVENTION In recent years, the increased occurrence of hospital-acquired infections has had serious implications for both patients and healthcare workers in addition to the antihydrogen conditions encountered in normal life. Hospital-acquired infections typically originate in a hospital or long-term care setting. Consequently, hospitals and other healthcare facilities extensively use materials impregnated or otherwise foreseen with antimicrobial agents for a variety of topical applications, such as wound dressings and drapes, and/or sterile drapes and articles that need to be discarded after a short usage due to infection risks.

Surgical drapes are presently made from woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene fabrics, and are typically used during surgical procedures to isolate the patient from the operating room personnel and the environment of the operating room. Contact with contaminated liquids through surgical drapes has been considered as a primary source of bacterial contamination for patients. Typically, drapes equipped with chemical antimicrobial agents are employed to avoid this, which typically must be present at a relatively high concentration to achieve the desired level of efficacy. The use of antibacterial or antifungal agents in non-woven fabrics is for instance disclosed in U.S. Pat. No. 4,111,922. Unfortunately, however, the required high levels of antimicrobial agents employed are undesired in many cases. For instance, the use of high levels of certain types of antimicrobial agents may be undesired due to an increased likelihood of contacting sensitive areas, such as wounds. And even if a patient does not suffer from adversary effects from contact with a chemical antimicrobial agent, most presently employed antimicrobial compositions loose efficacy over time, since the microbiological pathogens develop resistance, such as for instance exemplified by methicilin -resistant staphylococcus aureus (MRS A). This resistance spread is exacerbated by the low number of antibiotics in the development pipeline which could result in a major world-wide public health problem.

Various substrates coated with nanosilver particles or impregnated with sivler salts have been reported to develop antimicrobial properties, as for instance as disclosed by Ronen Gottesman et al, Langmuir, 2011, 27 (2), pp 720-726. However, the use and application of silver salts, or colloidal silver particles usually requires the use of complex application technologies, e.g. sonochemical application or impregnation with dispersions, which if applicable at all due to the sensitivity of in particular non-woven materials to water or solvents requires handling of solvents and their removal, as well as drying of the obtained products. For instance, a commonly reported approach involves to reduce a solution of silver nitrate and to deposit the silver particles on a polymeric fibre, e.g. nylon, via a process referred to as electroless deposition. The obtained silver laden polyamide is attached to a subsequent fibre layer. This renders the application process complex and cumbersome. Furthermore, the silver particles will be distributed over the whole material and not available at the contact area with moisture, such as in skin contact. Therefore, in order to be effective, such materials require a relatively high silver loading, which makes a widespread use prohibitively difficult. Yet further, due to the complexity and nature of this process, it is difficult to control the amount of silver deposited on the fibre and furthermore, the amount of silver deposited is limited by the surface area of the fibre.

For this reasons, the antimicrobial products which have been developed to date have all the features of dipping process and have short-term stability and weariness, while the method developed in the present invention has the ability to penetrate into the structure of woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene materials to increase effcieny and long term stability. Thus, antimicrobial effcetivines has not been successfully developed and applied to a substrate having the combination of characteristics described here in, as desired for an effective antimicrobial properties of wound dressing, facial masks, surgical drapes and surgical clothing, to filter materials, panty, bra, handkerchief, pad, scouring pad, , disposable sheets and similar applications as well as to a process for the preparation of the woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene fabric material.

This is also advantageous for application to porous or foam materials because antimicrobial agents are not incorporated into the material in areas that will never come into contact with the microbial pathogens. Likewise, hospitals, some office, house and generally facilities sensitive to microbiological pathogens have been increasingly facing issues with microbiological contamination of the air, spread through building air handling systems, specifically in Heating Ventilating and Air Conditioning (HVAC) systems. HVAC system components usually operate in a warm, dark and humid environment, which makes it an ideal breeding ground for microbes such as bacteria and/or fungi. The microbiological contamination cause odour in their mildest form, but generally may cause much graver issues. This is in particular relevant as building air handling and ventilation is increasingly employed. The microbial contamination frequently found includes fungi such as Aspergillus spp., Fusarium spp., Penicillium chrysogenum and/or Candida albicans, but also Legionella, a pathogenic Gram negative bacterium, including species that cause legionellosis or“Legionnaires' disease”, most notably, Legionella pneumophila, has caused many issues with infections transmitted through HVAC systems.

The presence of such pathogens is usually treated in various ways, including adding microbial chemical agents into the humid sections of HVAC systems. Accordingly, the use of filters and other parts in HVAC or general air handling systems, in particular filter elements with intrinsically antimicrobial activity would be highly advantageous.

As such, a need currently exists for equipping materials such as gloves, bedding textiles, surgical drapes, table paper, gowns, and facial masks, drape sheets, and others such as air and water filters with high and continuous antimicrobial activity at a relatively low level of an antimicrobial agent. Furthermore, this would allow storing such materials under non-sterile conditions.

Applicants have now surprisingly found that fabrics, both woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene with antimicrobial activity can be provided by a simple process which permits to prepare and/or convert the materials with high quality, high antimicrobial activity, low costs and long term stability.

Accordingly, the present invention relates to a fabric material having antimicrobial activity, comprising: (a) a woven, non-woven and non woven-cotton fabric material, and (b) fabric material having a thickness of from 5 to 100 nm, 10 to 70 gsm

The term“antimicrobial activity” as used herein refers to a material that destroys, inhibits or prevents the propagation, growth and multiplication of unwanted microbial organisms such as bacteria, fungia and viriis. The term“microbial organisms” or“microbes” includes, but is not limited to, microorganisms, bacteria, undulating bacteria, spirochetes, spores, spore -forming organisms, gram-negative organisms, gram-positive organisms, yeasts, fungi, moulds, viruses, aerobic organisms, anaerobic organisms and mycobacteria. Specific examples of such organisms include the fungi Aspergillus niger, Aspergillus flavus, Rhizopus nigricans, Cladosporium herbarium, Epidermophyton floccosum, Trichophyton mentagrophytes, Histoplasma capsulatum, and the like; bacteria, such as Pseudomonas aeruginosa, Escherichia coli, Proteus vulgaris, Staphylococcus aureus, Staphylococcus epidermis, Streptococcus faecalis, Klebsiella, Enterobacter aerogenes, Proteus mirabilis, other gram-negative bacteria and other gram-positive bacteria, mycobactin and the like, as well as yeasts, such as Saccharomyces cerevisiae, Candida albicans, and the like. Additionally, spores of microorganisms, viruses and the like are microbial organisms within the scope of the present invention. Preferably, the antimicrobial layer lie on on the all surface of woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene fabric material and that imparts the antimicrobial activity comprises a combination polymeric guanidine derivative based on a diamine containing oxyalkylene chains between two amino groups, with the guanidine derivative representing a product of polycondensation between a guanidine acid addition salt and a diamine containing polyoxyalkylene chains between two amino groups, hexamethylenediamine (1,6- hexanediamine) guanidinium derivatives, particularly to combinations of oligo(2- (2-ethoxy)ethoxy ethyl guanidinium chloride), modified polyhexamethylene guanidine (PHMG) as an antimicrobial agent., poly(hexamethylendiamine guanidinium chloride), Polietheramine derivatives (JEFFAMINE EDR-148), Polietheramine (Triethyleneglycol diamine (TEGDA) enzymes, PGPR, amino acids, antioxidants like humic acids and some natural products like phytotherapeutic plant extracts for the production calculated on the other metal(s) by weight. The present invention also advantageously relates to woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene fabric material, whereby high cation capacity of synthesiz antimcirobial material inhibited all of the bacteria and fungia nad viriis contaminated surface. The present invention refers to fabric materials including to woven, nonwoven, cotton, nonwoven- cotton blended, polyethylene and polipropilen and polystyrene fabric material and/or film surfaces.

Woven or nonwoven fabric materials are usually defined as sheet or web structures bonded together by entangling of fibres or filaments, and/or by perforating films mechanically, thermally or chemically. They are typically flat, porous, sheet like structures that are made from separate fibres, and/or from molten plastic or plastic film. Woven or nonwoven fabrics provide specific functions such as absorbency, liquid repellence, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, filtering, use as a bacterial barrier and sterility. Woven fabric according to the present invention may be formed from fibres Woven fabrics according to the invention are typically prepare from fibres and/or yam prepared from fibres, such as synthetic fibres, natural fibres, or combinations thereof.

The process usually involves steps such as weaving or knitting, and it does not necessarily require converting fibres to yam.

Synthetic fibres include, for example, polyester, acrylic, polyamide, polyolefin, polyaramid, polyurethane, regenerated cellulose, and blends thereof. More specifically, polyester, polyethylene and polipropilen, high impact polystyrene includes, for example, polyethylene terephthalate, polytriphenylene terephthalate, polybutylene terephthalate, polylactic acid, and combinations thereof. Polyamide includes, for example, nylon-6, nylon-6.6, and combinations thereof. Polyolefins include polypropylene, polyethylene, and combinations thereof. Polyaramid includes, for instance poly-p-phenyleneteraphthalamid (i.e., Kevlar (iD), poly-m-phenyleneteraphthalamid (i.e., Nomex (E)), and combinations or variations thereof.

Natural fibres include, for example, wool, cotton, flax, cellulose and blends thereof.

The fabric may be formed from fibres or yarns of any size, including microdenier fibres and yams (fibres or yams having less than one denier per filament). The fibres or yams may have deniers that range from less than about 1 denier per filament to about 2000 denier per filament or more preferably, from less than about 1 denier per filament to about 500 denier per filament, or even more preferably, from less than about 1 denier per filament to about 300 denier per filament.

Furthermore, the fabric may be partially or wholly comprised of multi -component or bicomponent fibres or yarns which may be splittable along their length by chemical or mechanical action. The fabric may be comprised of fibres such as staple fibre, filament fibre, spun fibre, or combinations thereof.

The fabric may be of any variety, including but not limited to, woven fabric, knitted fabric, nonwoven fabric, or combinations thereof. They may optionally be coloured by a variety of dyeing techniques, such as high temperature jet dyeing with disperse dyes, thermosol dyeing, pad dyeing, transfer printing, screen printing, or any other technique that is common in the art for comparable, equivalent, traditional textile products. If yams or fibres are treated by the process of the current invention, they may be dyed by suitable methods prior to fabric formation, such as, for instance, by package dyeing or solution dyeing, or after fabric formation as described above, or they may be left undyed.

The film may include thermoplastic materials, thermoset materials, or combinations there of.

Thermoplastic or thermoset materials may include polyolefin, polyester, polyamide, polyurethane, acrylic, silicone, melamine compounds, polyvinyl acetate, polyvinyl alcohol, nitrile rubber, ionomers, polyvinyl chloride, polyvinylidene chloride, chloroisoprene, or combinations thereof. The polyolefin may be polyethylene, polypropylene, ethylvinyl acetate, ethylmethyl acetate, or combinations thereof. Polyethylene may include low density or high density polyethylene. The film may have a thickness of between 1 and 500 pm, preferably between 2 pm and 250 pm, or even more preferable between about 3 and 100 pm.

Typically, the process to prepare a non-woven fabric does not involve process steps such as weaving or knitting, and it does not require converting fibres to yarn, and yam to fabric. Nonwoven fabrics may be engineered for a single use, limited life or a durable fabric.

The nonwoven fabric material preferably is a nonwoven web which may include nonwoven webs manufactured by any of the commonly known processes for producing nonwoven webs. As used herein, the term“nonwoven web” refers to a fabric that has a structure of individual fibres or filaments which are randomly and/or unidirectionally interlaid in a mat-like fashion.

For example, the fibrous nonwoven web can be made by carded, air laid, wet laid, spunlaced, spunbonding, electro spinning or melt-blowing techniques, such as melt- spun or melt-blown, or combinations thereof. Spunbonded fibres are typically small diameter fibres that are formed by extruding molten thermoplastic polymer as filaments from a plurality of fine, usually circular capillaries of a spinneret with the diameter of the extruded fibres being rapidly reduced. Meltblown fibres are typically formed by extruding the molten thermoplastic material through a plurality of fine, usually circular, die capillaries as molten threads or filaments into a high velocity, usually heated gas (e.g., air) stream which attenuates the filaments of molten thermoplastic material to reduce their diameter. Thereafter, the meltblown fibres are carried by the high velocity gas stream and are deposited on a collecting surface to from a web of randomly disbursed meltblown fibres. Any of the non woven webs may be made from a single type of fibre or two or more fibres that differ in the type of thermoplastic polymer and/or thickness. Staple fibres may also be present in the web. The presence of staple fibres generally provides a loftier, less dense web than a web of only melt blown microfibers. Preferably, no more than about 20 weight percent staple fibres are present, more preferably no more than about 10 weight percent. Webs containing such staple fibre are for instance disclosed in U.S. Pat. No. 4,118,531.

The nonwoven fabric may advantageously be fashioned or shaped in any suitable article. Such an article may optionally further comprise one or more layers of scrim. For example, either or both major surfaces may each optionally further comprise a scrim layer. The scrim, which is typically a woven or nonwoven reinforcement made from fibres, is included to provide strength to the nonwoven article. Suitable scrim materials include, but are not limited to, nylon, polyester, fibreglass, and the like. The average thickness of the scrim can vary. Typically, the average thickness of the scrimranges from about 25 to about 100 pm, preferably about 25 to about 50 pm. The layer of the scrim may optionally be bonded to the nonwoven article. A variety of adhesive materials can be used to bond the scrim to the polymeric material. Alternatively, the scrim may be heat-bonded to the nonwoven. The micro fibres of the nonwoven fabric material substrate typically have an effective fibre diameter of from about 0.5 to 15 pm, preferably from about 1 to 6 pm, as calculated according to the method set forth in Davies, C. N.,“The Separation of Airborne Dust and Particles,” Institution of Mechanical Engineers, London, Proceedings IB, 1952.

The nonwoven fabric material preferably has a basis weight in the range of about 10 to 400 g/m², more preferably about 10 to 100 g/m². The average thickness of the nonwoven fabric material is preferably about 0.1 to 10 mm, more preferably about 0.25 to 5 mm for the non-functionalized, and uncalendared fabric material.

The minimum tensile strength of the nonwoven web is at least 3.0, preferably at least 4.0 Newtons. It is generally recognized that the tensile strength of nonwovens is lower in the machine direction than in the cross-web direction due to better fibre bonding and entanglement in the latter. Nonwoven web loft is measured by solidity, a parameter that defines the solids fraction in a volume of web. Lower solidity values are indicative of greater web loft. Useful nonwoven fabric materials typically have a solidity of less than 20%, preferably less than 15%, as defined in WO-A-2010151447. Solidity is used herein to refer to the nonwoven fabric material itself and not to the functionalized nonwoven. When a nonwoven fabric material contains mixtures of two or more kinds of fibres, the individual solidities are determined for each kind of fibre using the same L[nonwoven] and these individual solidities are added together to obtain the web's solidity, dt.

As an example, the nonwoven fabric material before calendering or grafting preferably has an average pore size of 14 pm, calculated from a thickness of 0.34 mm, effective fibre diameter of 4.2 um and solidity of 13%. After calendering the nonwoven web will have a thickness of 0.24 mm and solidity of 18% with an average pore size of 8 pm. The term“average pore size”, also referred to as average pore diameter is related to the arithmetic median fibre diameter and web solidity and can be determined as disclosed in WO-A-2010/151447.

The nonwoven fabric material preferably has a mean pore size of 1-40 pm, preferably 2-20 pm. Mean pore size may be measured according to ASTM F 316- 03“Standard Test Methods for Pore Size Characteristics of Membrane Filters by Bubble Point and Mean Flow Pore Test Method B” using Freon TF™ as the test fluid. The nonwoven fabric material may be formed from any suitable thermoplastic polymeric material. Suitable polymeric materials include, but are not limited to, polyolefins, poly(isoprenes), poly(butadienes), fluorinated polymers, chlorinated polymers, polyamides, polyimides, polyethers, poly(ether sulfones), poly(sulfones), poly(vinyl acetates), copolymers of vinyl acetate, such as poly(ethylene)-co-poly(vinyl alcohol), poly(phosphazenes), poly(vinyl esters), poly(vinyl ethers), poly( vinyl alcohols), and poly(carbonates).

Suitable polyolefins include, but are not limited to, poly(ethylene), poly(propylene), poly(l -butene), copolymers of ethylene and propylene, alpha olefin copolymers (such as copolymers of ethylene or propylene with 1 -butene, 1-hexene, 1-octene, and 1-decene), poly(ethylene-co-l -butene) and poly(ethylene-co-l-butene-co-l- hexene).

Suitable fluorinated polymers include, but are not limited to, poly(vinyl fluoride), poly(vinylidene fluoride), copolymers of vinylidene fluoride (such as poly(vinylidene fluoride-co-hexafluoropropylene), and copolymers of chlorotrifluoroethylene (such as poly(ethylene-co-chlorotrifluoroethylene).

Suitable polyamides include, but are not limited to, nylon 6, nylon 6,6, nylon 6, 12 poly(iminoadipoyliminohexamethylene), poly(iminoadipoyliminodecamethylene), and polycaprolactam. Suitable polyimides include poly(pyromellitimide). Suitable poly(ether sulfones) include, but are not limited to, poly(diphenylether sulfone) and poly(diphenylsulfone-co-diphenylene oxide sulfone).

Suitable copolymers of vinyl acetate include, but are not limited to, poly(ethylene- co-vinyl acetate) and such copolymers in which at least some of the acetate groups have been hydrolyzed to afford various poly(vinyl alcohols) including, poly(ethylene-co- vinyl alcohol).

Preferred polymers are inherently hydrophilic and are readily grafted by ionizing radiation, such as by exposure to e-beam or gamma radiation. Preferred polymers include of polyamides and ethylene vinyl alcohol polymers and copolymers. For surgical drapes or gowns or similar apparel, preferred nonwoven fabric sheets are made from wood pulp; fibres of a thermoplastic polymeric material, including melt-blown polymer fibres, such as melt-blown polypropylene fibres, and synthetic polymer fibres, such as polypropylene, polyester, polyethylene, polyolefin, polyamide polyethylene and polipropilen, high impact polystyrene and nylon fibres; cellulosic nonwoven fibres such as nonwoven rayon; and combinations of these materials. The term“thermoplastic” is used herein to refer to materials which are solid at room temperature, i.e. from 22° C. to 30° C., but which soften or melt when heated to temperatures above room temperature. Thermoplastic materials are extrudable at temperatures in excess of 50° C. Preferred thermoplastic materials soften or melt at temperatures above about 50° C. and below about 1,000° C., in order that the material will not melt during transportation but be melted by commonly-used surgical lasers. More preferred thermoplastic materials soften or melt at temperatures between 60° C. and 500° C. For surgical drape applications where patient comfort is a factor, preferably at least 10 percent of the nonwoven fibres have lengths greater than about 0.06 cm.

Preferred nonwoven fabric sheets include a layer of polyethylene film sandwiched between two layers of nonwoven rayon, melt-blown polypropylene fabric; and a combination of wood pulp and polyester fibres. Nonwovens are typically manufactured by putting small fibres together in the form of a sheet or web, and then binding them either mechanically as in the case of felt, by interlocking them with serrated needles such that the inter-fibre friction results in a stronger fabric, with an adhesive; thermally; by applying binder, preferably in the form of powder, paste, or polymer melt, and then melting the binder onto the web by increasing temperature. The nonwoven fabric material may be a nonwoven web, paper, film, foam, elastomeric material, which may be supplied with the antimicrobial composition.

If the nonwoven fabric has a weblike stmcture, it may preferably be a spunbond web, meltblown web, bonded carded web, airlaid web, coform web, and/or hydraulically entangled web. Polymers suitable for making nonwoven webs include, for example, polyolefins, polyesters, polyamides, polycarbonates, copolymers and blends thereof, etc. Most embodiments of the laminate of the present invention employ a nonwoven web formed from olefin-based polymers, which are non-polar in nature. Suitable polyolefins include polyethylene, such as high density polyethylene, medium density polyethylene, low density polyethylene, and linear low density polyethylene; polypropylene, such as isotactic polypropylene, atactic polypropylene, and syndiotactic polypropylene; polybutylene, such as poly(l- butene) and poly(2-butene); polypentene, such as poly(l-pentene) and poly(2- pentene); poly(3 -methyl -1-pentene); poly(4-methyl-l-pentene); and copolymers and blends thereof. Suitable copolymers include random and block copolymers prepared from two or more different unsaturated olefin monomers, such as ethylene/propylene and ethylene/butylene copolymers. Such polymer(s) may preferably also contain additives, such as processing aids to impart desired properties to the fibres, residual amounts of carriers, pigments or colorants, and so forth.

If desired, the nonwoven fabric may have a multi-layer structure. Suitable multi layered materials may include, for instance spunbond/meltblown/spunbond (SMS) laminates and spunbond/meltblown (SM) laminates. Various examples of suitable SMS laminates are described in U.S. Pat. No. 4,041,203, U.S. Pat. No. 5,213,881, U.S. Pat. No. 5,464,688, U.S. Pat. No. 4,374,888 U.S. Pat. No. 5,169,706 and U.S. Pat. No. 4,766,029. Nonwoven fabric materials are usually made in at least two steps. In a first step, fibres are cut to a few centimetres length, and then dispersed on a conveyor belt, where they are spread in a uniform web by a wetlaid process or by carding. Combining melt blown and spunbond fibres results in SM or SMS webs nonwoven fabric materials, which are strong and offer the intrinsic benefits of fine fibres such as fine filtration, low pressure drop as used in face masks or filters and physical benefits such as acoustic insulation as used in dishwashers, for instance for disposable diaper and hygiene care products.

Melt blown non woven fibres are typically produced by extruding melted polymer fibres through a spin net or die to form long thin fibres which are stretched and cooled by passing hot air over the fibres as they fall from the die. The resultant web is collected into rolls and subsequently converted to finished products. The extremely fine fibres typically differ from other in that they have low intrinsic strength but much smaller size offering.

Nonwoven fabrics are typically bonded by using either resin or thermally. Bonding can be throughout the web by resin saturation or overall thermal bonding or in a distinct pattern via resin printing or thermal spot bonding.

The nonwoven fabric may advantageously also contain additional fibrous components. For example, a nonwoven fabric may be entangled with a fibrous component using any of a variety of entanglement techniques known to a person skilled in the art, such as cellulosic fibres or glass fibres. A typical hydraulic entangling process utilizes high pressure jet streams of water to entangle fibres to form a highly entangled consolidated fibrous structure, e.g., a nonwoven fabric. Fibreglass is wetlaid into mats for use in roofing and shingles. Synthetic fibre blends are wetlaid along with cellulose for single -use fabrics.

Other materials may also be used to form the nonwoven fabric material. For example, the nonwoven fabric may contain an elastomeric polymer, such as natural rubber latex, isoprene polymers, chloroprene polymers, vinyl chloride polymers, styrene-ethylene -butylene-styrene block copolymers, styrene -isoprene- styrene block copolymers, styrene -butadiene-styrene block copolymers, styrene-isoprene block copolymers, styrene -butadiene block copolymers, butadiene polymers, styrene-butadiene polymers, carboxylated styrene -butadiene polymers, acrylonitrile -butadiene polymers, carboxylated acrylonitrile -butadiene polymers, acrylonitrile-styrene-butadiene polymers, carboxylated acrylonitrile -styrene- butadiene polymers, derivatives thereof, and so forth. The fabric material may optionally be treated with liquid-repellency additives, antistatic agents, surfactants, colorants, antifogging agents, fluorochemical blood or alcohol repellents, and/or lubricants.

The woven or non-woven fabric materials according to the present invention can be prepared particularly cheaply and in large economical scale with high throughput processes, giving access to comparatively cheap antimicrobial products that may be employed for applications where prior to the invention the use of antimicrobial materials would have been unsuccessful due to the prohibitive costs involved. The antimicrobial composition may be tailored according to the use and potential contamination targeted. The economics can be maintained due to the extremely low amounts of metal deposited. The metal layer has a high adhesion, while other properties, such as flexibility of the substrate, remain unchanged.

Two different technologies are used in the introduction of the synthesis material to the structure of non-woven material. While the effect is achieved by immersion method, but a shorter period of time is provided, in the case of entering the material during the production phase, the formation of longer periods than both efficiency and stability is ensured.

The subject woven and non-woven antimicrobial materials may advantageously be employed in various applications to inhibit the growth of microorganisms. For example, they may be used in treatments or surroundings where hospital -acquired infections caused by bacteria, viruses, fungi, or parasites. The subject woven and non-woven antimicrobial materials preferably have an antibacterial activity of at least 3, more preferably at least 4, yet more preferably at least 5 as determined by the ISO 20743:2007 method, using Staphylococcus aureus ATCC 6538 and/or Klebsiella pneumoniae ATCC 4352. This activity is advantageously measured on the on the metalized surface as described herein below.

Antimicrobial woven and non-woven fabric materials according to the invention may advantageously be employed in numerous applications, including: hygiene articles, such as diapers, feminine hygiene articles, wet wipes, bandages, facial masks and wound dressings; medical isolation and/or surgical apparel and gowns, surgical drapes and covers, surgical scrub suits, masks, caps and generally disposable clothing; filters for fluids and air, sensitive packaging materials and so on. These filters are typically employed in filtration and processing steps in the pharmaceutical, chemical, food and mineral and oil processing industry, and may be formed into cartridge and bag filters, vacuum bags, and allergen membranes.

The present invention further also relates to a integrarted syhthezis material to woven or non- woven fabric material such as sheet cloth and its applications as two different technologies which are used in the introduction of the synthesis material to the structure of non-woven material, and while the effect is achieved by immersion method, but a shorter period of time is provided, in the case of entering the material during the production phase, the formation of longer periods than both efficiency and stability is ensured. The effect is desirable in high quality air environments such as hospitals and health care facilities, but also public spaces, such as preferably public transport, e.g. underground trains, large office buildings, schools, housing and the like. The present invention further relates to a filter comprising the metallised non-woven material with bacterial growth suppressing activity. The filter, and cartridges comprising the nonwoven fabric material according to the invention may be employed for air and/or liquid filtration, such as for instance for drinking water. In the latter it may advantageously remove smells, discolouration and chemical contaminants such as chlorine besides its antimicrobial function. The antibacterial filter comprising material according to the invention can further positively reduce the microbial load, and hence impact air quality in stand alone ventilation circuits in the automotive and aerospace industries.

The woven non-woven fabric may be used alone, or in combination with other materials for a further spectrum of products with diverse properties, such as components of apparel, home furnishings, health care, engineering, industrial and consumer goods. In addition, the (non)woven fabric material substrate may also serve other purposes, such as providing water absorption, barrier properties, etc. Any of a variety of (non)woven fabric material substrates may be applied with the antimicrobial composition in accordance with the present invention. Accordingly, the present invention also relates to the use of the materials according to the invention, or those materials obtainable according to above described process, for the control or restriction of antimicrobial growth. Although several specific embodiments of the present invention have been described in the detailed description above, this description is not intended to limit the invention to the particular form or embodiments disclosed herein since they are to be recognised as illustrative rather than restrictive, and it will be obvious to those skilled in the art that the invention is not limited to the examples

Nonwoven abrasive articles used for cleaning, such as nonwoven abrasive scrub pads, can harbor microorganisms such as bacteria and fungi that can thrive and rapidly multiply in moist environments. Consequently, it is desirable to use materials that are effective at cleaning and that control or prevent the growth of unwanted microorganisms on nonwoven abrasive articles. Although various approaches have been taken to try to solve the problem of microbial growth on nonwoven abrasive articles used for cleaning, such approaches have not produced nonwoven abrasive articles that have long lasting effects on a broad spectrum of organisms

The nonwoven substrate can be of any desired weight. In a particular embodiment, the weight of the nonwoven substrate material per unit area can be in a range of about 100 GSM to 500 GSM, such as 150 GSM to 200 GSM, or about 160 GSM to about 180 GSM (i.e., grams per square meter, or g/m²). Suitable nonwoven substrates are comprised of fibers that are bound together by various methods or mechanisms, such as typically, by being sprayed with a binder formulation. A suitable non-limiting binder composition is shown below in Table A of the Examples. The nonwoven substrate material can have any desired suitable loft. In a specific embodiment the loft is 12-14 mm and a weight per unit area within a range of 230-250 GSM. In accordance with an embodiment, the nonwoven substrate material can include one or more binders to adhere and interlock the threads (fibers) of the nonwoven web.

In accordance with an embodiment, the abrasive article provides abrasive performance and broad spectrum antimicrobial effectiveness against S. aureus, and one or more of K. pneumoniae, Bacillus, and E. coli as defined above with respect to the first antimicrobial agent.

Surprisingly, the broad spectrum antimicrobial effectiveness lasts over an extended period of time and/or extensive usage of the abrasive article. In an embodiment, the abrasive article possesses broad spectrum effectiveness even after extensive usage, such as even after completing 5000 cycles according to the Cyclic Abrasion Test, which equates to cleaning approximately 500 utensils or approximately 15 days of cleaning with the abrasive article. The Cyclic Abrasion Test is described in greater detail below in the Examples. Further, the abrasive article possesses broad spectrum effectiveness even after being subjected to three hours of ball milling according to the Accelerated Life Test, which is described in greater detail below in the Examples.

In an embodiment, the abrasive article can have a particular weight, defined as grams per square meter, or GSM. In an embodiment, the abrasive article can have a weight of at least at least 300 GSM, at least 500 GSM, at least 750 GSM, at least 850 GSM, or at least 1050 GSM.

In accordance with an embodiment, the abrasive article can have a GSM_ratio of the weight of the nonwoven substrate material prior to being impregnated and sprayed with the first ad second formulation (GSMnonwoven) to the weight of the final cured abrasive article (GSM_fmai). In an embodiment, the abrasive article can have a GSM ratio (i.e., GSM_n0nwoven:GSM_finai) of at least 1:2, meaning that the weight in GSM of the final cured abrasive article has at least twice a much weight as the nonwoven substrate material from which it was formed. In an embodiment, the GSM_ratio can be at least 1 :3, at least 1:4, or at least 1:5. In a non-limiting embodiment, the GSM_{ratio C}an be not greater than 1:15, such as not greater than 1 :6, or not greater than 1:5. It will be appreciated that the GSM_rati0 can be within a range of any minimum or maximum value noted above. In a particular embodiment, the GSM_ratio can be within a range of 1 :3 to 1 :6, and more particularly within a range of 1 :4 to 1:5.

Breast surgery may be undertaken for any of a number of reasons. A mastectomy (surgical removal of the breast) may be required to remove breast cancer. A biopsy such as an open excisional biopsy (lumpectomy) or needle aspiration may be used to obtain a sample of a suspected tumor for analysis. Mastopexy (breast lift) or breast augmentation may be undertaken for cosmetic reasons. Mammoplasty (breast reduction) may be undertaken for cosmetic reasons or to treat physical symptoms. Reconstructive surgery may restore the contour of a breast after accident or other surgery, or may be used to amend the contour of a healthy breast to match the contour of a breast changed by other surgery. As in all surgeries, surgeries of the breast share the characteristic that an incision or a penetration of the skin overlying the breast is required. As in all surgeries, surgeries of the breast involve a risk that bacteria or other infectious agents may travel through the skin penetration and cause an infection.

The control of microbes on the undergarments of a post-surgery patient, such as a brassiere of a breast surgery patient, helps to reduce infection and to improve the emotional well-being of the patient. A brassiere is worn continuously for many hours, providing a relatively warm, relatively moist environment in which microbes may multiply. The problem posed by microbes is exacerbated in the case of the post-operative breast surgery patient due to the fact that tenderness and loss of arm strength or mobility resulting from the breast surgery may make maintaining a high degree of personal cleanliness difficult for the patient. The control of microbes in the brassiere of a post-breast surgery patient further helps to prevent anxiety and to maintain the emotional well being of the patient by preventing odors or discoloration resulting from the presence of the microbes

Thus there is a need for antimicrobials that are safe, non-toxic, long-lasting and effective at controlling contamination and infection by unwanted microbial organisms, with minimal development of resistant or polyresistant microorganisms.

In one aspect, the present invention relates to novel, antimicrobial polymers. In another aspect, the present invention relates to antimicrobial pharmaceutical compositions and methods for treatment of microbial infections in a mammal.

In another aspect, the present invention relates to antimicrobial pharmaceutical compositions and methods for wound management.

In another aspect, the present invention relates to antimi crobial pharmaceutical compositions and methods for treatment of infections of the skin, oral mucosa and gastrointestinal tract.

In yet another aspect, the present invention relates to antimicrobial compositions and methods of preventing, inhibiting, or eliminating the growth, dissemination and accumulation of microorganisms on susceptible surfaces, particularly in a health- related environment.

The ionene polymers and compositions of the invention are also particularly useful for inhibiting the growth and dissemination, of microorganisms, particularly on surfaces wherein such growth is undesirable. The term“inhibiting the growth of microorganisms” means that the growth, dissemination, accumulation, and/or the attachment, e.g. to a susceptible surface, of one or more microorganisms is impaired, retarded, eliminated or prevented. In a preferred embodiment, the antimicrobial compositions of the inventtions are used in methods for inhibiting the growth of an organism on susceptible surfaces in health-related environments. The term“health-related environment” as used herein includes all those environments where activities are carried out directly or indirectly, that are implicated in the restoration or maintenance of human health. A health -related environment can be a medical environment, where activities are carried out to restore human health. An operating room, a doctor’s office, a hospital room, and a factory making medical equipment are all examples of health-related environments. Other health-related environments can include industrial or residential sites where activities pertaining to human health are carried out such as activities including food processing, water purification, recreational water maintenance, and sanitation.

The term“susceptible surface” as used herein refers to any surface whether in an industrial or medical setting, that provides an interface between an object and the fluid. A surface, as understood herein further provides a plane whose mechanical structure, without further treatment, is compatible with the adherence of microorganisms. Microbial growth and/or biofilm formation with health implications can involve those surfaces in all health -related environments. Such surfaces include, but are not limited to, scalpels, needles, scissors and other devices used in invasive surgical, therapeutic or diagnostic procedures; implantable medical devices, including artificial blood vessels, catheters and other devices for the removal or delivery of fluids to patients, artificial hearts, artificial kidneys, orthopedic pins, plates and implants; catheters and other tubes (including urological and biliary tubes, endotracheal tubes, peripherally insertable central venous catheters, dialysis catheters, long term tunneled central venous catheters, peripheral venous catheters, pulmonary catheters, Swan-Ganz catheters, urinary catheters, peritoneal catheters), urinary devices (including long term urinary devices, tissue bonding urinary devices, artificial urinary sphincters, urinary dilators), shunts (including ventricular or arterio-venous shunts); prostheses, (including breast implants, penile prostheses, vascular grafting prostheses, heart valves, artificial joints, artificial larynxes, otological implants), vascular catheter ports, wound drain tubes, hydrocephalus shunts, pacemakers and implantable defibrillators, and the like. Other surfaces include the inner and outer surfaces of pieces of medical equipment, medical gear worn or carried by personnel in the health care settings and protective clothing for biohazard or biological warfare applications. Such surfaces can include counter tops and fixtures in areas used for medical procedures or for preparing medical apparatus, tubes and canisters used in respiratory treatments, including the administration of oxygen, solubilized drugs in nebulizers, and anesthetic agents. Additional surfaces include those surfaces intended as biological barriers to infectious organisms such as gloves, aprons and faceshields.

Surfaces in contact with liquids are particularly prone to microbial growth and/or biofilm formation. As an example, those reservoirs and tubes used for delivering humidified oxygen to patients can bear biofilms inhabited by infectious agents. Dental unit waterlines similarly can bear biofilms on their surfaces, providing a reservoir for continuing contami nation of the system of flowing and aerosolized water used in dentistry.

Other surfaces related to health include the inner and outer surfaces of equipment used in water purification, water storage and water delivery, and those articles involved in food processing equipment for home use, materials for infant care and toilet bowls.

In accordance with the invention, a method for preventing, inhibiting or eliminating the growth, dissemination and/or accumulation of microorganisms on a susceptible surface (including but not limited to the formation of biofilms) comprises the step of contacting such surface with an antimicrobial agent, or composition thereof of the invention, with an amount sufficient to prevent, inhibit or eliminate such growth, dissemination and/or accumulation, i.e., with an effective amount.

In some embodiments, the antimicrobial agent of the invention is an antimicrobial preservative, attesting to the ability of the formulations of the invention to suppress microbial growth, reduce microbial infestation, treat products or surfaces to improve product resistance to microbial infestation, reduce biofilm, prevent conversion of bacteria to biofilm, prevent or inhibit microbial infection, prevent spoilage, retard or minimize or prevent quorum sensing, and retard microbial reproduction.

The antimicrobial agent is capable of endowing a product, or the product surface, with a biological resistance to at least one biological effect, which in the absence of such agent would eventually bring about a short-term or long-term damage to the product. In the context of the invention, the antimicrobial agent improves the product's resistance to a certain environmental condition.

Nonwoven and woven materials are used to make a variety of products for use in various industries. There remains a need, however, for such materials having antimicrobial properties to eliminate microorganisms in various applications, including applications requiring an antimicrobial barrier (e.g., wound dressings, face masks, etc). It is known that combinations of containing polyoxyalkylene chains between two amino groups, Hexamethylenediamine (1,6-hexanediamine) guanidinium derivatives, particularly to combinations of oligo(2-(2-ethoxy)ethoxy ethyl guanidinium chloride), modified polyhexamethylene guanidine (PHMG) as an antimicrobial agent., poly(hexamethylendiamine guanidinium chloride), Polietheramine derivatives (JEFFAMINE EDR-148), Polietheramine (Triethyleneglycol diamine (TEGDA) enzymes, PGPR, amino acids, antioxidants like humic acids and some natural products like phytotherapeutic plant extracts can be used to prevent growth of bacteria, fungua and virus in wound dressing, facial masks, surgical drapes and surgical clothing, to filter materials, panty, handkerchief, pad, scouring pad, , disposable sheets and similar applications made by nonwoven, woven and non woven -cotton materials. In accordance with the invention, a method for preventing, inhibiting or eliminating the growth, dissemination and/or accumulation of microorganisms on a susceptible surface (including but not limited to the formation of biofilms) comprises the step of contacting such surface with an antimicrobial agent, or composition thereof of the invention, with an amount sufficient to prevent, inhibit or eliminate such growth, dissemination and/or accumulation, i.e., with an effective amount on wound dressing, facial masks, surgical drapes and surgical clothing, to filter materials, panty, handkerchief, pad, scouring pad, , disposable sheets and similar applications. As used herein“contacting” refers to any means for providing the compounds of the invention to a surface to be protected from, microbial growth and/or biofilm formation. Contacting can include spraying, wetting, immersing, dipping, painting, bonding, coating, adhering or otherwise providing a surface with a compound or composition in accordance with the invention. A“coating” refers to any temporary, semipermanent, or permanent layer, covering a surface. A coating can be a gas, vapor, liquid, paste, semi solid or solid. In addition a coating can be applied as a liquid and solidify into a hard coating. Examples of coatings include polishes, surface cleaners, caulks, adhesives, finishes, paints, waxes, polymerizable compositions (including phenolic resins, silicone polymers, chlorinated rubbers, coal tar and epoxy combinations, epoxy resins, polyamide resins vinyl resins, elastomers, acrylate polymers, fluoropolymers, polyesters and polyurethane, latex). Silicone resins, silicone polymers (e.g. RTV polymers) and silicone heat cured rubbers are suitable coatings for use in the invention and described in the art. Coatings can be ablative or dissolvable, so that the dissolution rate of the matrix controls the rate at which the compositions of the invention are delivered to the surface. Coatings can also be non-ablative, and rely on diffusion principals to deliver a composition of the invention to the wound dressing, facial masks, surgical drapes and surgical clothing, to filter materials, panty, handkerchief, pad, scouring pad, , disposable sheets and similar applications surface.
