Development of the Methods of Finishing Non-Woven Fabric With Brass Nanoparticles

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, processing 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.
