The natural dyestuff, grape skin dye was manufactured from grape skin by boiling in 0.1% HCI solution, eliminating the sugar and powdering in freeze dryer. Cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured grape skin dye to investigate the dyeability and color fastness. Dyeing was operated in acidic dyebath of pH 4 because the grape skin is anionic. The color of dyed fabrics were affected on temperature of dyeing solution. Under 80$^{C}$, the color of dyed fabrics were red or violet, but changed to brown in laundering. Above 100$^{C}$, the color were brown and safe in laundering. Dyeabilities on wool, silk, and nylon fabrics were good, especially silk fabrics were dyed deeper than others. Dyeability was developed with concenturation of dyeing solution. All the dyed fabrics were excellent in color fastness to crocking and laundering. Light fastness was low to moderate. The light fastness of dyed nylon fabrics were as poor as grade 1, but they could be improved to grade 3∼4 by aftertreatment with gallic acid.
