Metal covered textile applications gaining wider use - a nano-silver coatings provides protection against microbes, nano-zinc oxide coatings - protection against ultraviolet radiation and anti-bacterial protection, but the nano-copper coatings exhibited even anti-fungal properties (Qian, 2004). However, the properties of nanocovered materials haven’t completely explored, particularly in the using process released a very active nano-ions 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 device (GDV). GDV devices broad range of applications allows new perspectives for control of liquids structural properties change, including water structural changes tracking out (Коротков, 2001). 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. This article reflects the gait of methodologies development and the results of structural changes in the water on purpose to determine levels of pollution and expression of pollution influence on liquids structure.
