Abstract 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. |
