Mimosa tenuiflora extract has been used in food industry as an additive and in textile and leather industry as a colorant. Two types of fabrics, ready to be dyed white and indigo dyed fabrics, were dyed with M. tenuiflora extract. The fabrics were mordanted after dyeing with six different metal salts. Colorimetric evaluations of fabrics were carried out by spectrophotometer. Colour fastness to washing, rubbing and light were performed. Colour strength of fabrics was calculated from Kubelka-Munk formula. Highest vividness (C*) values were obtained by Ni mordant. Moderate fastness values were observed. However poor wet rubbing fastness values were observed in the case of indigo dyed fabrics due to lack of good wet rubbing fastness of indigo itself.
