An overview of the methods for the synthesis of NP-Ag by chemical and green methods using polymers and plants as reducing agents and stabilizers is presented. The analysis of the advantages and disadvantages of the methods used for the synthesis of NP-Ag is carried out. The latest research on the use of NP -Ag in the textile industry is also presented, with a focus on imparting antibacterial and fungicidal properties to textile materials.

Petroleum takes the leading place in fuel and energy sector. It is a basis of fuel and energy balance of advanced countries economics. Light oil proven reserves reducing is a general trend of modern oil industry development. Almost the entire increase in reserves is due to viscous heavy sour oil [1][2]

Changes in the color characteristics of knitted fabrics after bactericidal finishes were studied by the colorimetric method. Antibacterial activity was tested with regard to gram-negative bacterium E. coli and gram-positive bacterium S. aureus. The strongest color changes due to the presence of Ag NPs were observed on samples dyed with lighter shades, where the color difference was mainly caused by the change in lightness and brightness. After treatment with silver NPs, the colors in samples dyed with Navy K-EN and Black NN are deepened, that is, the color intensity increases many times and the reflection coefficient decreases. Due to this effect, darker color tones can be achieved using less dye. The dyed knitted fabrics modified with Ag-carboxymethyl starch (AgCMS) NPs exhibited excellent antibacterial properties regardless of the dye color used. The dyeing did not affect the antibacterial activity of fabrics modified with AgCMS nanocomposites. The research on the resistance of the dyed knitted fabrics treated with nanocomposite AgCMS solution to washing showed the preservation of a sufficiently high antimicrobial activity, slightly decreasing only after the 10th wash in a washing solution. This is proved by exceptional resistance to washing of knitted fabrics modified with AgCMS. The results of the research allow one to solve the problem of expanding the range of antibacterial products and special clothes by treating textile materials with silver and carboxymethyl starch NPs.
