Metal covered textile applications gaining wider use - a nanosilver coatings provides protection against microbes, nanozinc oxide coatings - protection against ultraviolet radiation and antibacterial protection, but the nanocopper coatings exhibited even antifungal properties. However, the properties of nanocovered materials haven’t completely explored, particularly in the using process released a very active nanoions/nanoparticles of heavy metals influence on the operator’s and the user's health and the environment. One of the ways to obtain quantitative information on pollution levels from the early stages of its development, is testing the liquid with gas discharge visualization bioelectrography (GDV) device. For successfully application of bioelectrography devices options to study of changes in water structure arising from metal covered textile washing process, indispensable to develop the testing methodology, which contains a sample selection, development of optimal test conditions, data processing and interpretation technology formation.
