ʷ The dyeing of Tencel fabric with Coptis chinensis Franch was studied. The colorant was extracted with distilled water under various concentrations of dyestuff, times, mordants. UV-VIS spectra were obtained to find the maximum wavelength and absorbance of colorant. Tencel fabric was dyed with different mordants in pre and post-mordanting methods. Maximum wavelength of spectrum was 343 nm, and K/S value of pre-mordant was higher than post-mordant. Aluminium and stannic mordants changed color from yellow to blue-greenish and red-bluish. Colorfastnesses of light, and washing were low grade, but that of perspiration was increased.
