Abstract:

The article considers the current status and prospects for the use of natural antimicrobial agents in technologies for providing functional properties to textile materials, in particular antibacterial ones. The main classes of biologically active compounds of plant origin (flavonoids, phenolic acids, terpenoids, tannins, etc.) that exhibit bactericidal and fungicidal activity are identified. The results of studies on the use of extracts of Mimusops elengi, Aloe vera, curcumin, juglone, essential oils, as well as combined compositions with hydrolyzed collagen, chitosan and polymer dispersions are analyzed. The advantages of such antimicrobial agents in technologies for antimicrobial treatment of textile materials for military and civil purposes are outlined. Experimental data on the effectiveness of natural antimicrobial agents against a wide range of pathogenic microorganisms are summarized. Plant extracts and essential oils, due to their biological activity, biodegradability and low toxicity, are a promising alternative to traditional synthetic biocidal agents, has been confirmed. The need for further research on stability, compatibility with textile fibers, and technological aspects of implementing technological solutions into production has been proven. The results of the study on the growth of the global market of natural antimicrobial agents from 6,3 to 18,7% indicate the potential of using natural components in technologies of antimicrobial treatment of textile materials for military and civil purposes. The most promising are extracts of Mimusops elengi, Aloe vera, curcumin, juglone, essential oils, polymer dispersions with hydrolyzed collagen, chitosan.
