Investigation of Dyeing Properties of Vine (Vitis vinifera L.) Leaves on Wool and Cotton Fabrics

In this work, Vitis vinifera L. leaf was used to dye wool and cotton fabrics at different dyeing conditions. The solutions of 0.1 M K2Cr2O7 and AlK(SO4)2•12H2O were used as mordant agents. Pre-mordanting, together mordanting and last mordanting methods were applied at a medium pH value in the dyeing of the fabrics. According to the fastness results, it can be concluded that cotton fabrics have better fastness values than wool fabrics. The best dyeing method was obtained using last mordanting method with K2Cr2O7 as a mordant for cotton fabric. The results also reveal that the V. vinifera shall probably be an important raw material for dyeing process of cotton fibers.
