Eco-friendly dyeing of leather and wood samples using Parthenocissus quinquefolia L. fruits aqueous extract

The present study is relevant to extracting natural colorant from Parthenocissus quinquefolia L. fresh fruits and applying the extracted dye on leather and wood samples in the presence and absence of various mordants. The effect of mordant type (copper sulfate (CuSO4.5H2O) ferrous sulfate (FeSO4.7H2O) and alum (KAI(SO4)2.12H2O) with different mordanting methods (pre-mordanting, meta-mordanting, post-mordanting) on dyeing quality was also examined. The effects of mordants on the color of dyed samples were investigated in terms of CIELab (L*, a*, b*) and K/S values. The dyed samples' light, washing, and rubbing fastness were evaluated according to ISO standards. Although generally good fastness values were obtained for all three mordants, light fastness was low. These results suggest that P. quinquefolia fruits have sufficient potential in dyeing leather and wood.
