The availability of bactericidal knitted cotton fabrics by processing a biodegradable bactericidal nano compositioncontaining nanoparticles of silver and Na-carboxymethyl starch is studied in this work. The nanocomposite based onNa-carboxymethyl starch and silver nanoparticles were successfully fixed on the surface of knitted cotton fabrics throughthe formation of links between carboxymethyl groups of carboxymethyl starch and nanosilver, as well as air interlacingbetween nano composition and material. The analysis of the change in the colour of knitted cotton fabrics afterprocessing them with a solution of the nano composition of silver and Na-carboxymethyl starch showed the stability ofthe colouristic indicators of the colour during antibacterial treatment.Knitted cotton fabrics treated with the developed nano composition exhibit high antibacterial activity towardsgram-positive fungal cultures of Bacillus subtilis, Staphylococcus aureus, and gram-negative Pseudomonas aeruginosa.Consistency of colour and the presence of bacteriostatic properties after repeated washing of knitted cotton fabricsconfirms the stability of the antimicrobial properties of reusable fabrics.
