Abstract
The natural dyestuff(chestnut dye) was manufactured from chestnut hulls by boiling in 0.5 NaOH solution and powdering in freeze dryer. To investigate the dyeability and color fastness, cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured chestnut dye. Dyeing operation was carried in acidic dyebath of pH 4-5 because the chestnut dye is anionic. Dyeabilities on wool, silk and nylon fabrics were good, especially nylon fabrics were dyed deeper than others. But dyeability on cotton fabrics was not good. All the dyed fabrics showed excellent color fastness to crocking. Color fastness to laupdering of them were moderate to good. Also light fastness of them were moderate to good except nylon. The light fastness of dyed nylon fabrics was as poor as grade 1. But they could be improved to grade 4 by aftertreatment with gallic acid.
