The scientific study examines the functional groups of the oregano shell dye for dyeing textile materials , the expansion of color capabilities and capabilities capable of resisting microorganisms . The aim of the study is to create a natural additive to save resources , environmentally friendly , natural coloring products , easy to manufacture and use manufacturing technology . Extraction of the walnut shell is necessary when dyeing and finishing fabrics and textiles . At the present stage , it is relevant to obtain and study natural dyes for textile materials . The use of natural dyes will improve the hygienic properties of products and increase the environmental friendliness of the finishing process . Thanks to the active extraction of natural dyes and expanded color shades , the possibilities of introducing natural dyes into the textile industry in the future are high . This is due to the fact that the raw material base is extensive , and the compliance of natural dyes with international environmental standards , as well as one of the priorities provided for by the strategy , is the rational use of natural raw materials . 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 , various modifying components were added to the dyes . The use of the resulting coloring agent in the dyeing of textile fibers will replace the import of synthetic textile dyes .
