Definitions
- the matter of invention is the method of furnishing textile during wet washing, especially applicable in large scale laundries providing bedding wash services for hospitals, hotels and related places, as well as work clothes.
- fleece, cotton, and synthetic fiber surfaces are known, including impregnation to make them, for instance antiseptic, waterproof, or flame resistant. It has been also recognized that silver and copper reveal antimicrobial properties.
- Ciofi et al (2005) [Ciofi N. et al. Copper Nanoparticle /Polymer Composites with Antifungal and Bacteriostatic Properties, Chem. Mater., 17 (2005), 5255-5262] have described polymer nanocomposite containing nanomolecules of copper as antimicrobial and antifungal agent. It was proven experimentally that nanoparticles were released from nanocomposite surface and resulted in growth inhibition of fungi and other pathogenic microorganisms. The biological activity corroborated with metal nanoparticle content.
- liquid composition possesing antimicrobial and antifungal properties, dedicated to cleaning of interiors, like floors and walls, and sanitary area and equipment, containing among others, at least one nanosilver(O) colloid up to 500 ppm concentration at 1% to 99% weight and/or at least one nanocopper(O) colloid up to 500 ppm concentration at 1% to 99% weight was described in Polish patent application no P.390497.
- the nanoparticles of silver and/or copper as well as their oxides are obtained by Turkevich method (i.e. by readuction of metal cations with citrate or ascorbic acid) to get colloidal mixture with polymer, from which the granules of polymer-nanoparticles composite are formed by extrusion. Then the granules of nanocomposite are mixed with base polymer and synthetic fibers are formed by spinning.
- Such obtained fabric showed antibacterial, antifungal, and fungal cytostatic properties even after many washing cycles.
- liquid mixture was dosclosed, containing peroxide bleacher and chelating agent for copper and/or iron and/or manganese, at the preliminary washing step and compositions applicable in this process.
- the method of furnishing fibers with antibacterial silver particles in entire washing was also described.
- the fibers are treated with mixture of specimen containing colloidal silver and/or ionic silver and softener agent composed of surfactants in such proportion that mixture contains 100 to 5000 mg Ag/dm 3 and/or fibers are sprayed after centrifuging step with mixture containing colloidal silver, surfactants, and/or glycerol, and/or plant starch, and/or polyvinylpyrrolidone, and/or polyvinyl alcohol; the mixture containing 100 to 5000 mg Ag/dm 3 as silver nanoparticles of size no higher then 100 nm, followed by drying.
- the nanoparticles of silver on fiber surface are stabilized at further step of wet pressing (mangling) or dry pressing (ironing) upon heating.
- the last step of water washing is mangling/ironing of textile, usually performed at 180 - 230 °C, depending on kind of textile. In that process the elimination of most of bacteria take place. However, the gained status is not permanent; during the use of textile the number of bacteria and fungi increases. This remains a fundamental problem in case of bedclothes and work clothes used in hospitals and other health care places, health care for the elderly places, hotels, prisons, and so on. In such areas the increase of bacteria population, especially of causal microorganisms, may lead to developing of infections and infectious disseases in human populations of lowered dissease resistance.
- Furnishing of textile during washing process in which textiles undergo preliminary washing, essential washing, water rinsing and water removal, neutralization and/or starching, and/or softening, final centrifuging, drying, mangling (wet pressing) or ironing (dry pressing) steps, according to this invention, consists of that:
- the textile are treated with specimen containing nanoparticles of copper and copper(II) oxide and/or other compounds of copper(II) of 20- 50 nm diameter average size, or with specimen containing nanoparticles of copper and copper(II) oxide and/or other compounds of copper(II) of 20- 50 nm diameter average size as well as nanoparticles of silver and silver(I) oxide and /or other compounds of silver(I) 20- 50 nm diameter average size, the weigh ratio of metals being between 10.T and 1 : 10, the metal nanoparticles are introduced in a way that ensures the final amount of 10 - 1000 mg of copper or copper and silver per 1 kg of dry textile; furthermore at the softening step the known softener is introduced into washing bathwater and after the centrifuging step the known refiner is introduced, followed by water removal and drying and afterwards the nanoparticles of copper or copper and silver and their oxides are stabilized on textile surface by exposing the textile to high temperature
- copper and silver are introduced as specimen containing bimetalic nanoparticles of alloy type composed of metallic copper and metallic silver, of average 20-50 diameter size, with weigh ratio of metals from 10: 1 to 1 :10 and/or mixture of specimen composed of Cu/CuO and Ag/Ag 2 0 nanocomposite of core-sheath (metal core and metal oxide sheath) of the size below 20 nm diameter, with weigh ratio of metal to metal oxide being between 1 : 1 and 1 :5.
- the textile is treated with specimen A containing nanoparticles of copper and/or copper(II) oxide and/or other compounds of copper(II) as well as softener, and then is treated with specimen B, containing nanoparticles of silver and/or silver(II) oxide and/or other compounds of silver(I) as well as softener.
- the textile is treated, preferably splashed, with specimen A, containing nanoparticles of copper and/or copper(II) oxide and/or other compounds of copper(II), as well as refiner, and then is treated with specimen B containing nanoparticles of silver and/or silver(II) oxide and/or other compounds of silver(I) as well as refiner.
- softener contains anionic and/or cationic and/or non-ionic surfactants
- refiner contains anionic and/or cationic and/or non-ionic surfactant and/or glycerol and/or plant starch and/or polyvinylpyrrolidone and/or polyvinyl alcohol.
- the residual water content is 45%, which further decreases upon mangling.
- the textiles after washing and water removal are subjected to mechanical and thermal work -up in mangling or ironing step accompanied by immobilization of nanoparticles of copper and/or silver and/or oxides of these metals on textile.
- Textile mangling or ironing is performed at 180 - 230°C temperature, depending on kind of textile.
- Upon heating the water evaporates, while nanoparticles of copper and/or silver and/or CuO and/or Ag 2 0 are mechanically pressed into fabric. Also upon heating the reduction of copper(II) and silver(I) into metallic copper and silver occur, respectively.
- Metal nanoparticles are formed in situ.
- the fabrics gain antibacterial, bacteriostatic, and antifungal properties, which are adjusted at every washing/mangling cycle.
