In this study, extraction of dyestuff from chestnut shell wastes and dyeing properties were investigated. Firstly, feed/solvent (F/S): 1/10-1/20 (g/ml), time: 1-2 h, solvent: water, water+NaOH (2.5%, 5%, 10%) parameters at 90°C were examined for the extraction of chestnut shell. 43.61% extraction yield was obtained in water+10% NaOH, F/S: 1/10 at 90°C for 1 hour as optimum parameters. Chestnut shell extract produced in optimum conditions was used as a dyeing agent in leather process. Potassium… Expand
