Abstract
The article presents the results of a study on the development of dyeing technology for wool materials using natural dyes. Increasing the ecological and functional value of textile materials is achieved through the use of natural pigments of plant origin and effective auxiliary substances that contribute to the strong fixation of the dye on the fiber. Modern approaches to the intensification of dyeing processes, including physicochemical methods, allowing to ensure a high degree of uniformity of staining, color resistance to external influences and preservation of physical and mechanical properties of wool fabrics, are considered. Optimization of the dyeing parameters of the concentration of dyes and modifiers, temperature and time processing, and acidity of the medium was carried out. The qualitative characteristics of the painted samples were studied, including the intensity and durability of the color, the uniformity of the dye, as well as the effect on the tactile properties of the material. The proposed technological solutions provide environmental safety, energy efficiency and the possibility of applying dyeing technology in production processes. Developed dye technology can be used in the production of natural textiles with decorative and functional properties in demand in the light industry, including for the manufacture of clothing, accessories and interior textiles.
