Comparative Analysis of the Structures of Textile Materials Using Various Types of Modified Natural Dyes

The study presents the results of research work on IR spectroscopy of dyed fabrics with natural dyes and with the addition of mordants to improve the physicochemical properties of shoe material, and also describes a comparative analysis of the functional groups of the extract of natural dyes from onion peel, hypericum and tansy for dyeing textile materials that have the ability to resist microorganisms. At the present stage, it is relevant to obtain and study natural dyes for textile materials. This article highlights various natural sources and the possibilities of using these substances in textiles to impart antimicrobial properties, and also discusses the results of IR spectroscopy of the dyed materials. The use of natural dyes will improve the hygienic properties of products and increase the environmental friendliness of the finishing process. IR spectroscopic studies of textile materials using the developed dyes were carried out in the work. To improve the quality of dyeing and chemical properties of dyes, various modifying components were added to the dyes.
