 note = {For deep and fast mordant dyeing of cotton, silk, wool, and nylon fabrics, a colorant of onion skin was mordant dyed with cupric chloride and acetate. The colorant was extracted by using boiled water. The cloths were first mordanted in 0.1 mol/L cupric salt solutions at 30℃ for 50 min. The mordanted cloths were dyed in the extracted solution at a liquor to fabric ratio of 1:50 at 70~80℃ for 30 min. The k/s values and the hues in terms of L*, a*, and b* of the dyed cloths were measured with a spectrophotometer. The washing fastnesses and color transfers of the dyed cloths were estimated by the standard method. Visual perceptions of color indicated that the wool cloth is appears as greenish-brown, the silk as reddish ocher, the nylon as dark yellow-orange, and the cotton as yellow-orange. The k/s values indicated a maximum at 420~430 nm with the levels in the order of wool > silk > nylon > cotton. The grades of color changing and fading on washing were 4 and 4-5 for cotton cloth, 2-3 for silk, 3-4 for wool, and 4 and 4-5 for nylon. The grades of color transfers of the dyed cloths on washing were all 5. Therefore, we obtained a deeper color and a good grade of washing fastness except for those with silk cloth.},
