The textile industry is highly polluting, especially in the dyeing stage, which drives the search for sustainable alternatives for dyeing fabrics. Natural dyes, such as turmeric, have been considered a less polluting option, due to their biodegradable properties and concern for sustainability. Furthermore, after the COVID-19 pandemic, interest in textile materials with antimicrobial properties increased, leading to the study of natural compounds, such as turmeric, which has antimicrobial, antioxidant and antiinflammatory properties. In this sense, the objective of the work was, the protection of the natural dye from the turmeric rhizome, the determination of the ideal dyeing conditions depending on the variation in the dye concentration, the analysis of the dyeing kinetics through adsorption isotherms, the evaluation the antimicrobial capacity of the extract before and after fixation on fabric, and verification of the dyeing of 100% cotton samples with natural turmeric extract, according to specifications for fastness to washing, fastness to wet rubbing and fastness to light. Despite the antimicrobial potential of the extract, its practical application in tissue may be restricted, as the percentage obtained does not reach the standards considered ideal for antimicrobial evidence. However, the results of this study lay a solid foundation for future investigations and possible applications in the area of dyeing with antimicrobial properties. In relation to dyeing, the presence of the mordant played a crucial role in color fixation and stability, influencing the intensity and concentration of the textile material.
