The present work is aimed at producing variety o.lcolored samples of wool, silk and cotton from natural dye extracted from onion scales for the application in the field of conservation o.l archaeological textiles. TInts, wool, silk and cottonfabrics were dyed at three dye concentrations usingfive mordants, namely alum, tin chloride, potassium dichromate, copper su(jate andferrous su(late. D(flerent strong bright fast colors were obtained. The dyeability, i.e. color and light fastJ1ess ratings were found to depend on the fclbric type, dye concentration as well as the mordant used. Wool samples showed the best dyeability and lightfastness rating followed by silk then cotton samples. High dye concentration gave the highest dyeability and stability to light. Also it was found that lightfastness o.lthe onion scales dye on the three fabrics is very good on using copper sulphate mordant. The least values were obtained with tin chloride mordant, especial{v on cotton samples. Unmordanted wool and silkfabrics samples gave medium values, while cotton samples recorded low light fastness ones.
