Determination of antimicrobial activity of textile fabrics treated with encapsulated nanodispersion biocidal systems

Popis výsledku v původním jazyce

Research article: Journal of Materials Science & Engineering, 2015, Volume 4, Issue 5, Page 113. Encapsulated nanodispersion biocidal systems (ENBS) based on biocide masterbatches for controlled releases of active ingredients to extend the protection of surfaces have a potential for the development of a new generation of more environmentally friendly products. ENBS will be utilized as progressive binders for functional fabrics. Newly developed ENBS textiles can prevent damage caused by microorganisms. Antimicrobial activity of textiles finished with ENBS was tested according to CSN EN ISO 20743. At textiles with ENBS it was found that their antibacterial activity increases with time. Moreover the higher biocidal activity was exhibited even after repeated washes at 60 °C. This phenomenon can be explained by migration of biocidal components to the surface of the textile fibre. After overcoming the potential barrier due to the presence of an anionic emulsifier the particles diffuse into the aqueous phase depending on the product solubility. The concentration of the biocide on the surface of the textile fibre increases with increasing temperature and time of washing. Textiles finished with ENBS meet requirements for long term functionality.
