Studies have been conducted on the process of obtaining brass nanoparticles by means of reduction with environmentally friendly preparations in order to give biocidal properties to non-woven fabric . The aim of the study is to modify a non-woven material using silver nanoparticles to give it biocidal properties . The effective composite preparation developed for biocidal finishing of textile materials is relatively inexpensive , environmentally and toxicologically safe . Its application opens up prospects for manufacturing a wide range of competitive , environmentally friendly , bio-resistant textile materials for various purposes . Process conditions of antibacterial finishing of textile materials were the followings : an aqueous solution with brass nanoparticles was sprayed onto the surface of a non-woven fabric , then dried and heat treated at 180 °C on a thermal press . To study the biocidal activeness of heat-treated material , a microbiological investigation was carried out . Non- woven fabric processed on the basis of brass nanoparticles obtains pronounced antifungal activeness in terms of investigating C.albicansATCC 2091 and C.albicansATCC 10231 test strains . Also , experiments on toxic and skin-irritating effects of non-woven material processed by the proposed method showed its safety for human health . The developed product based on silver nanoparticles provides high indicators of bio-resistance of textile material and meets the environmental requirements for textile auxiliary substances . In the production of nonwovens , p rocessing with this composition can be combined with the emulsification of a mixture of fibers , or carried out after the formation of the canvas with subsequent heat treatment and calendering .
