Perelshtein et al. (2009) [Perelshtein I, Applerot G, Perkas N, Wehrschetz-Sigl E, Hasmann A, Guebitz, G, Gedanken A (2009) CuO-cotton nanoparticles: formation, morphology and antibacterial activity. Surf Coat Technol 204:54] uvedli, že tenká vrstva oxidů kovů, kromě jiných oxidu měďnatého, nanesená na povrch bavlněného vlákna, vykazuje antibakteriální aktivitu vůči Staphylococcus aureus.Perelshtein et al. (2009) [Perelshtein I, Applerot G, Perkas N, Wehrschetz-Sigl E, Hasmann A, Guebitz, G, Gedanken A (2009) CuO-cotton nanoparticles: formation, morphology and antibacterial activity. Surf Coat Technol 204: 54] reported that a thin layer of metal oxides, among other copper oxide, deposited on the surface of the cotton fiber, showed antibacterial activity against Staphylococcus aureus.
Borkow a Gabba (2004) [Borkow G, Gabbay J (2004) Putting copper into action: copper impregnates, products with potent biocidal activities. FASEB J 18(14): 1728-1730] předvedli, že oxid měďnatý umístěný na syntetických vláknech vykazuje široké spektrum biologické aktivity, např. antibakteriální, antimykotickou, protivirovou, proti roztočům.Borkow and Gabba (2004) [Borkow G, Gabbay J (2004) Putting Copper into Action: Copper Impregnates, Products with Potent Biocidal Activities. FASEB J 18 (14): 1728-1730] have shown that copper oxide placed on synthetic fibers exhibits a broad spectrum of biological activity, eg, antibacterial, antifungal, antiviral, mites.
Antibakteriální a antimykotické vlastnosti mědi byly také popsány Gracem et al (2009) Grace M., Bajpai S.K., Chand N. Copper (II) ions and copper nanoparticles-loaded chemically modified cotton cellulose fibers with fair antibacterial properties, Joumal of Applied Polymer Science 113 (2009) 757-766], jenž uvádí uvolnění mědi(II) z vláken celulózy, která byla upravena oxidací jodistanem a následně byly nanočástice mědi(0) středního průměru 29 nm navázány na chitosan redukcí tetrahydroboritanem sodným. Takto upravená vlákna měla velmi vysokou antibakteriální aktivitu vůči E. coli.The antibacterial and antifungal properties of copper have also been described by Grace et al (2009) Grace M., Bajpai SK, Chand N. Copper (II) ions and copper nanoparticles-loaded chemically modified cotton cellulose fibers with fair antibacterial properties, Joumal of Applied Polymer Science 113 (2009) 757-766], which discloses the release of copper (II) from cellulose fibers that have been treated with periodate oxidation and subsequently copper nanoparticles (0) of 29 nm mean diameter were coupled to chitosan by reduction with sodium borohydride. The treated fibers had a very high antibacterial activity against E. coli.
Ciofí et al (2005) [Ciofi N. et al. Copper Nanoparticle /Polymer Composites with Antifungal and Bacteriostatic Properties, Chem. Mater., 17 (2005), 5255-5262] popsal polymemí nanokompozit obsahující nanočástice mědi jako antibakteriální a antimykotický činitel. Bylo experimentálně prokázáno, že nanočástice se uvolnily z povrchu nanokompozitu, následkem čehož došlo k inhibici růstu plísní a jiných patogenních mikroorganismů. Biologická aktivita byla v korelaci s obsahem nanočástic kovu.Ciofi et al (2005) [Ciofi N. et al. Copper Nanoparticle / Polymer Composites with Antifungal and Bacteriostatic Properties, Chem. Mater., 17 (2005), 5255-5262] described a polymer nanocomposite containing copper nanoparticles as an antibacterial and antifungal agent. It has been experimentally demonstrated that nanoparticles have been released from the surface of the nanocomposite, thereby inhibiting the growth of fungi and other pathogenic microorganisms. The biological activity was correlated with the content of metal nanoparticles.
Popsané vlastnosti stříbra a mědi měly za následek jejich využití v praxi.The described properties of silver and copper resulted in their use in practice.
Tekutá kompozice vykazující antibakteriální a antimykotické vlastnosti, určena k čištění interiérů jako podlah a stěn, také sanitárních ploch a vybavení, obsahující kromě jiného alespoň jeden koloid nanostříbra(O) o koncentraci do 500 ppm v množství 1 až 99 hmotnostních procent a/neboA liquid composition exhibiting antibacterial and antifungal properties, for cleaning interiors such as floors and walls, as well as sanitary facilities and equipment, containing, inter alia, at least one nanosilver (O) colloid having a concentration of up to 500 ppm in an amount of 1 to 99 weight percent;
- 1 CZ 306782 B6 alespoň jeden koloid nanomědi(O) o koncentraci do 500 ppm v množství 1 až 99 hmotnostních procent, byla popsána v polské patentové přihlášce P390497.At least one nanoparticle colloid (0) having a concentration of up to 500 ppm in an amount of 1 to 99 weight percent has been described in Polish patent application P390497.
V případě tkanin byly popsány způsoby nanášení a umístění zmíněných kovů na jejich povrch. Toto bylo realizováno různými chemickými a fyzikálními metodami.In the case of fabrics, methods for depositing and placing said metals on their surface have been described. This was accomplished by various chemical and physical methods.
Způsob impregnace tkanin nanočásticemi stříbra je popsán v polské patentové přihlášce P3 87686. Při tomto postupu jsou tkaniny ošetřeny chemickými sloučeninami jako: kyselina octová a/nebo roztok hydroxidu sodného a benzoy(chloridu a/nebo roztoky polymerů jako: polyakrylamid, polyvinylpyrrolidon, polyvinylalkohol, kyselina polyakrylová, s cílem nahradit skupinu hydroxylovou (-OH) funkčními skupinami odpovídajícími typu modifikující látky, anebo snížit počet -OH skupin na povrchu. Upravené tkaniny jsou pak impregnovány koloidním roztokem obsahujícím 100 až 2000 mg Ag/dm3, získaným redukcí soli stříbra(I) tetrahydroboritanem sodným anebo kyselinou citrónovou. Poté je z vláken odstraněna voda, výhodně sušením neutrálním plynem.A method for impregnating fabrics with silver nanoparticles is described in Polish patent application P3 87686. In this process, fabrics are treated with chemical compounds such as: acetic acid and / or sodium hydroxide solution and benzoy (chloride and / or polymer solutions such as: polyacrylamide, polyvinylpyrrolidone, polyvinyl alcohol, acid) polyacrylic, to replace the hydroxyl group (-OH) with functional groups corresponding to the type of modifying agent, or to reduce the number of -OH groups on the surface, the treated fabrics are then impregnated with a colloidal solution containing 100-2000 mg Ag / dm 3 obtained by reduction of silver salt Then, water is removed from the fibers, preferably by neutral gas drying.
Jiný postup je popsán v patentu US 8 183 167 Bl, podle něhož jsou textilie pokryty dobře dispergovanými nanočásticemi kovů antibakteriálních vlastností, jako stříbro a/nebo měď, které jsou vázány kovalentní vazbou. Práškové nanočástice kovů (stříbro a/nebo měď) se smíchají s roztokem obsahujícím složku kompatibilní s reaktivním blokovým kopolymerem, pak je jejich suspenze s polymerem přenesena do extrudéru, v němž jsou formovány granule kompozitu polymernanočástice. Výsledný nanokompozit je smíchán se základním polymerem za účelem získání vláken v procesu tkaní.Another method is described in U.S. Patent No. 8,183,167 B1, in which fabrics are coated with well-dispersed metal nanoparticles of antibacterial properties, such as silver and / or copper, that are bound by a covalent bond. Powdered metal nanoparticles (silver and / or copper) are mixed with a solution containing a component compatible with the reactive block copolymer, then their suspension with the polymer is transferred to an extruder in which granules of the polymer nanoparticle composite are formed. The resulting nanocomposite is mixed with the base polymer to obtain fibers in the weaving process.
V upraveném postupu jsou nanočástice stříbra a/nebo mědi, stejně jako jejich oxidy, získány Turkevichovou metodou (tj. redukcí kationtů kovů citrátem anebo kyselinou askorbovou), vzniká tak koloidní roztok s polymerem, z něhož jsou extruzí formovány granule kompozitu polymernanočástice. Poté jsou granule nanokompozitu smíchány se základním polymerem a tkaním jsou vytvořena syntetická vlákna. Takto získané tkaniny vykazují antibakteriální, antimykotické a fungistatické vlastnosti i po mnoha pracích cyklech.In the modified process, silver and / or copper nanoparticles, as well as their oxides, are obtained by the Turkevich method (i.e., reducing metal cations with citrate or ascorbic acid) to form a polymer colloid solution from which granules of the polymer nanoparticle composite are extruded. Then the nanocomposite granules are mixed with the base polymer and synthetic fibers are formed by weaving. The fabrics thus obtained exhibit antibacterial, antifungal and fungistatic properties even after many washing cycles.
Chattopadhyay a Patel (2010) [Chattopadhyay D.P and Patel B.H. Effect of nanosized colloidal copper on cotton fabric, Journal of Engineered Fibers and Fabrics 5 (2010) 1-6] popsali způsob získání koloidní mědi a její nanesení na bavlněná vlákna. Koloidní částice mědi průměrné velikosti 60 až 100 nm byly získány redukcí mědi(II) tetrahydroboritanem sodným za přítomnosti citrátu sodného. Impregnace tkaniny byla provedena ponořením do roztoku koloidní mědi (poměr roztok : tkanina byl 50:1) v 40 °C po dobu 60 min. a následně v 80 °C po dobu 30 min. Nakonec byl textil opláchnut vodou a vysušen vzduchem. Textilie impregnovaná mědí vykazovala antibakteriální aktivitu.Chattopadhyay and Patel (2010) [Chattopadhyay D.P and Patel B.H. Effect of nanosized colloidal copper on cotton fabric, Journal of Engineered Fibers and Fabrics 5 (2010) 1-6] described a process for obtaining colloidal copper and applying it to cotton fibers. Colloidal copper particles of average size 60-100 nm were obtained by reducing copper (II) with sodium borohydride in the presence of sodium citrate. The fabric was impregnated by immersion in a colloidal copper solution (solution: fabric ratio was 50: 1) at 40 ° C for 60 min. and then at 80 ° C for 30 min. Finally, the fabric was rinsed with water and air dried. The copper impregnated fabric showed antibacterial activity.
Popsány byly také metody umístění kovů na povrchu vláken během praní.Methods of placing metals on the fiber surface during washing have also been described.
V polské patentové přihlášce P322021 byla popsána tekutá směs obsahující peroxidové bělicí činidlo a chelatační činidlo pro měď a/nebo železo a/nebo mangan pro předepraní, a kompozice použitelné v tomto procesu.Polish patent application P322021 discloses a liquid composition comprising a peroxygen bleach and a chelating agent for copper and / or iron and / or manganese for prewash, and compositions useful in the process.
V jiné patentové přihlášce P397964 byl popsán způsob apretace vláken antibakteriálními částicemi stříbra v průběhu vlastního praní. Zejména během změkčování tkanin jsou vlákna vystavena působení směsi preparátu obsahujícího koloidní stříbro a/nebo iontové stříbro a změkčujícího činidla obsahujícího povrchově aktivní látky v takovém poměru, že směs obsahuje 100 až 5000 mg Ag/dm3 a/nebo jsou vlákna po odstředění postříkána směsí obsahující koloidní stříbro, povrchově aktivní látky a/nebo glycerol a/nebo rostlinný škrob a/nebo polyvinylpyrolidon a/nebo polyvinylalkohol; směs obsahuje 100 až 5000 mg Ag/dm3 jako nanočástice stříbra ne větší než 100 nm. Poté následuje sušení. Nanočástice stříbra jsou stabilizovány na povrchu vláken zahřátím ve fázi mandlování anebo žehlení.In another patent application P397964, a method of dressing fibers with antibacterial silver particles during the washing process has been described. Particularly during fabric softening, the fibers are exposed to a composition comprising a colloidal silver and / or ionic silver composition and a softening agent containing surfactants in such a ratio that the composition contains 100-5000 mg Ag / dm 3 and / or colloidal silver, surfactants and / or glycerol and / or vegetable starch and / or polyvinylpyrrolidone and / or polyvinyl alcohol; the mixture contains 100-5000 mg Ag / dm 3 as silver nanoparticles not greater than 100 nm. This is followed by drying. Silver nanoparticles are stabilized on the surface of the fibers by heating during the mangling or ironing phase.

Změkčující směs s výbornými antibakteriálními a protizápachovými vlastnostmi je známa z popisu patentu JP 2004/3006660. Změkčující směs obsahuje 0,01 až 10 hmotnostních procent mikrokapslí obsahujících stříbro průměru pod 500 nm. Toto nejen omezuje růst a proliferaci mikroorganismů, ale také potlačuje nepříjemný zápach v oděvech nošených anebo sušených ve vlhkých podmínkách, jako v létě anebo v deštivých dnech.A softening composition having excellent antibacterial and anti-odor properties is known from the disclosure of JP 2004/3006660. The softening composition comprises 0.01 to 10 weight percent of microcapsules containing silver below 500 nm in diameter. This not only limits the growth and proliferation of microorganisms, but also suppresses unpleasant odors in garments worn or dried in humid conditions such as summer or rainy days.
Patent JP 2007/046184 rozebírá způsob antimikrobiální úpravy přírodních vláken. Této úpravy bylo dosaženo praním vláken zvířecího anebo rostlinného původu se zásaditým detergentem pH 12 až 13 v horké vodě, následně postříkáním a impregnací iontovou vodou obsahující antimikrobiální činidlo jako částice stříbra, mědi anebo oxidu titaničitého ve formě nanočástic o průměru 1 až 20 nm, aby bylo dosaženo konečné koncentrace 150 až 5 ppm ve vlákně anebo na jeho povrchu, poté praním s detergentem s cílem umožnit antimikrobiálnímu činidlu průnik do vlákna, a nakonec sušením vlákna v 60 až 120 °C s cílem imobilizovat antimikrobiální činidlo ve struktuře vlákna.JP 2007/046184 discloses a method of antimicrobial treatment of natural fibers. This treatment was achieved by washing fibers of animal or plant origin with a basic detergent pH 12-13 in hot water, followed by spraying and impregnating with ionic water containing an antimicrobial agent such as silver, copper or titanium dioxide nanoparticles with a diameter of 1 to 20 nm. a final concentration of 150 to 5 ppm in or on the fiber is achieved, then by washing with detergent to allow the antimicrobial agent to penetrate into the fiber, and finally drying the fiber at 60 to 120 ° C to immobilize the antimicrobial agent in the fiber structure.
V jiném patentu EP 1 947 167 je popsána změkčující směs pro vlákna, obsahující 5 až 60 hmotnostních procent antistatického činidla, 0,5 až 5 hmotnostních procent zušlechťovadla, 1 až 5 hmotnostních procent aromát, 0,01 až 0,1 hmotnostních procent barviv a vodu s obsahem 1 až 10 000 ppm nanočástic kovů jako stříbro, zlato, měď, zinek a jejich biologicky aktivních sloučenin.Another patent EP 1 947 167 discloses a fiber softening composition comprising 5 to 60 weight percent antistatic agent, 0.5 to 5 weight percent refiner, 1 to 5 weight percent aromatics, 0.01 to 0.1 weight percent dyes, and water containing from 1 to 10,000 ppm of metal nanoparticles such as silver, gold, copper, zinc and their biologically active compounds.
Nevýhodou známých způsobů apretace je nemožnost provedení úpravy obsahu biologicky aktivních kovů v textiliích během jejich používání, což způsobuje pokles jejich antimikrobiální aktivity·A disadvantage of the known finishing methods is the impossibility of adjusting the content of biologically active metals in textiles during their use, which causes a decrease in their antimicrobial activity.
Posledním krokem vodního praní je mandlování/žehlení textilií, obvykle prováděné v teplotě 180 až 230 °C, v závislosti na druhu tkaniny. Tímto dochází k eliminaci většiny bakterií. Nicméně dosažený stav není trvalý, během používání textilií počet bakterií a plísní stoupá. Toto je základní problém v případě ložního prádla a pracovních oděvů používaných v nemocnicích a jiných zdravotnických zařízeních, pečovatelských domovech pro seniory, hotelech, věznicích apod. V těchto prostorách nárůst populace bakterií, zvláště patogenních, může vést k rozvoji infekcí a infekčních onemocnění u osob se sníženou imunitou.The last step of water washing is the mangling / ironing of fabrics, usually carried out at a temperature of 180 to 230 ° C, depending on the type of fabric. This eliminates most bacteria. However, the achieved state is not permanent, the number of bacteria and fungi increases during the use of textiles. This is a fundamental problem in the case of bed linen and work clothes used in hospitals and other healthcare facilities, nursing homes for the elderly, hotels, prisons, etc. In these areas, an increase in bacterial populations, particularly pathogenic, may lead to infections and infectious diseases in immunosuppressed.
I když úprava množství nanostříbra v textilu v průběhu pracího procesuje známa z patentové přihlášky P397964, neočekávaně jsme zjistili, že nanesení nanočástic stříbra a mědi dohromady jakožto přípravku obsahujícího nanokompozit Cu/CuO a Ag/Ag2O se strukturou typu jádro-obal je výhodnějším a efektivnějším řešením.Even though a plurality of nanosilver on the textile during the washing process is known from patent application P397964, unexpectedly we found that the deposition of silver nanoparticles and copper together as a composition containing nanocomposite Cu / CuO and Ag / Ag 2 O with the structure of the core-package is preferred, and more effective solution.
Cílem vynálezu je zdokonalení antibakteriálních, antimykotických vlastností a omezení šíření roztočů v textiliích v průběhu pracího procesu, obzvláště provozovaného ve velkém měřítku, ve srovnání se známými a popsanými postupy.It is an object of the invention to improve the antibacterial, antifungal properties and limit the spread of mites in textiles during a washing process, especially on a large scale, as compared to known and described processes.

-3 CZ 306782 B6 je dle vynálezu založen na zavedení nanočástic mědi anebo mědi a stříbra jako přípravku obsahujícího nanokompozity Cu/CuO a Ag/Ag2O typu jádro-obal v množství zajišťujícím 10 až 1000 mg nanočástic mědi anebo nanočástic mědi a stříbra na 1 kg suché látky, přičemž hmotnostní poměr kov-kov činí od 10:1 do 1:10, a poměr kov - oxid kovu činí od 1:1 do 5:1, a nanočástice mědi anebo mědi a stříbra jsou stabilizovány v povrchu textilie vystavením této textilie vysoké teplotě během žehlení nebo mandlování při 180 až 230 °C.According to the invention, it is based on the introduction of copper or copper and silver nanoparticles as a composition comprising Cu / CuO and Ag / Ag 2 O core-shell nanocomposites in an amount providing 10 to 1000 mg of copper or silver nanoparticles per 1 kg of dry matter, the metal to metal weight ratio being from 10: 1 to 1:10, and the metal to metal oxide ratio being from 1: 1 to 5: 1, and the nanoparticles of copper or copper and silver are stabilized in the fabric surface by exposure to high temperature fabrics during ironing or mangling at 180 to 230 ° C.
Výhodná velikost nanočástic mědi a stříbra je 20 až 50 nm.A preferred copper and silver nanoparticle size is 20 to 50 nm.
Obecně technologie praní poskytující textiliím antibakteriální vlastnosti obsahuje následující kroky:In general, the washing technology providing the fabric with antibacterial properties comprises the following steps:
a) předepraní(a) pre-wash
b) vlastní praní s dezinfekcí(b) self-cleaning with disinfection
c) máchání následované odsátím vodyc) rinsing followed by suction of water
d) neutralizace/škrobení/změkčení/impregnace přípravky mědi a/nebo stříbra(d) neutralization / starch / softening / impregnation with copper and / or silver preparations
e) finální odstředění(e) final centrifugation
f) sušení, mandlování anebo žehlení s průvodní imobilizací a ustálením nanočástic mědi a/nebo stříbra a/nebo oxidů kovů.f) drying, mangling or ironing with concomitant immobilization and stabilization of copper and / or silver and / or metal oxide nanoparticles.
V navrhovaném procesuje obsah zbytkové vody po praní oděvů 45%, tento dále klesá mandlováním. Textilie jsou po praní a odstranění vody vystaveny mechanickému a tepelnému zpracování během procesu mandlování nebo žehlení doprovázeného imobilizací nanočástic mědi nebo mědi a stříbra a oxidů těchto kovů na textilii. Mandlování nebo žehlení textilií probíhá při teplotě 180 až 230 °C, v závislosti na druhu textilie. Při zahřívání se voda odpařuje, zatímco nanočástice mědi a CuO nebo mědi a stříbra a CuO a Ag2O a/nebo Cu(II) ionty nebo Cu(II) a Ag(I) ionty a/nebo bimetalické nanočástice Cu/Ag jsou mechanicky zažehlené do látky. Taktéž při zahřívání dochází k redukci mědi(II) a stříbra(I) na kovovou měď a stříbro. Takto jsou formovány nanočástice kovů in šitu.In the proposed process, the residual water content after washing clothes is 45%, which further decreases by mangling. The fabrics are subjected to mechanical and heat treatment after washing and water removal during the mangling or ironing process accompanied by the immobilization of the copper or copper and silver nanoparticles and the oxides of these metals on the fabric. Almonding or ironing of fabrics takes place at a temperature of 180 to 230 ° C, depending on the type of fabric. Upon heating, the water evaporates while the copper and CuO or copper and silver nanoparticles and the CuO and Ag 2 O and / or Cu (II) ions or Cu (II) and Ag (I) ions and / or bimetallic Cu / Ag nanoparticles are mechanically ironed into fabric. Also, with heating, copper (II) and silver (I) are reduced to metallic copper and silver. In this way, metal nanoparticles are formed in situ.
Díky tomuto vynálezu látky získávají baktericidní, bakteriostatické a antimykotické vlastnosti, které jsou upravovány v každém cyklu praní/mandlování.Thanks to the present invention, the substances acquire bactericidal, bacteriostatic and antifungal properties which are modified in each wash / mangle cycle.
