Abstract :Natural dyestuffs, which took the place of synthetic dyestuffs in the past, have started to be used consciously again thanks to the increasing understanding of \`environmentally friendly textile\`. These natural dyestuffs are mostly obtained from plants or food waste. Coffee is the most consumed nutrient in the world after water. Therefore, there is a lot of waste of coffee in nature and it contains pigments that give it its natural color. In this study, products with different fiber contents insert ignore into journalissuearticles values(100% cotton, 98% cotton 2% elastane, 80% cotton 20% recycled cotton); were dyed using coffee waste, and different mordant substances insert ignore into journalissuearticles values(aluminum sulfate, chitosan, quetemary ammonium compounds);. It has been tried to reduce the amount of coffee waste used by dyeing with coffee wastes at different rates by weight insert ignore into journalissuearticles values(1/1, 2/1, 4/1, 8/1);. Thus, it is aimed to provide less waste to the environment and to increase the color efficiency by making a more sustainable dyeing process. In addition, it is aimed to give a new direction to the denim sector by improving the rubbing and washing fastness values of dyed products. As a result of the studies, products with a product weight/coffee waste weight ratio of 8/1 were obtained with high crocking and washing fastnesses and without major losses in color tone.
