AB - In this study, eco-friendly natural dyeing for pig leather was explored by using onion skin which is food waste. Sodium caseinate was used as a pre-treatment agent to improve dyeability of pig leather and its effect on dye uptake was investigated according to treatment concentration. Dye uptake of the pre-treated pig leather was increased by about two times compared to untreated one at 0.2% pre-treatment concentration. Onion skin colorant imparted YR color on pig leather. After mordanting, the color of pretreated/ dyed pig leather was varied from brick-red to khaki shades. However, mordanting did not improved dye uptake of the pre-treated/dyed pig leather significantly. The colorfastnesses of un-mordanted samples to light, dry cleaning, rubbing were grades 3-4, 5, and 4, respectively, which is good enough to meet all Korean Standard for Fastness of leather products. After mordanting, the light fastness of pig leather was improved to 4, 4-5 grade. The efficacy of sodium caseinate as a pre-treatment agent for pig leather was verified by improved dye uptake and good colorfastness. And, the natural dyeing of pig leather using food waste would be a significant sustainable way in terms of eco-friendliness and reuse of biomass to reduce environmental pollution.
