ʷ The purpose of this study was to investigate the dyeing properties of silk, wool, nylon and poly(ethylene teraphtlate)PET fabrics dyed with Tumeric(Curcuma longa) extracts. The dyeing property and color fastness were investigated by using the extracts and the post mordanting with Aluminum, Copper and Iron salts. In the UV-visible spectra, the maximum absorption of wavelength of the extract with methyl alcohol appeared at 420nm, and that of the extract with distilled water was at 415nm. Increasing the dyeing temperature, the K/S values of dyed fabrics were increased. The optimum dyeing condition was 3060 minute of dyeing time at pH 55.6. Surface colors of silk and wool became dark by using mordants compared to those of nylon and PET fabrics. The drycleaning fastness of fabrics dyed with the extracts was good. The laundering and light fastness were improved by using mordants.
