This article reflects one development stage of the formation process of metal coated textile quality control methodology based on the analysis of sewage electrograms. The experiment has been carried out with the help of gas discharge visualization camera. To determine how the electrogram parameters reflect the presence of nanoparticles in water, the ZnO nanoparticles have been added to five distilled water samples in the following concentrations: 10%; 8%; 6%; 4%; 2%. According to the experiment results, the electrography method can be used for textile zinc oxide coating durability testing.
