Summary/Abstract: The relevance of the results is due to the need to solve a set of problems related to both the expansion of the range of marketable products obtained from waste from coniferous plants and the reduction of environmental damage to the environment by wood processing enterprises. A process for the extraction of a complex of coloring substances from the bark of larch, fir and Siberian spruce was developed and implemented in laboratory conditions with an environmentally safe and cheap solvent – water. The modes of concentration and drying of natural dyes without loss of their color characteristics and other consumer properties have been developed. The possibility of using the obtained dyes for dyeing both natural and synthetic fibers is shown. The study of their biocidal activity in relation to sanitary indicative microorganisms made it possible to create textile materials with bactericidal properties.
