摘要：The fastness properties of the flower of Opuntia ficus-indica dyed cotton fabric have been studied using different combinations (1:3, 1:1 and 3:1) of various mordants, such as myrobolan-nickel sulphate, myrobolan-aluminium sulphate, myrobolan-potassium dichromate, myrobolan-ferrous sulphate and myrobolan-stannous chloride. The wash, rub, light and perspiration fastness of the dyed samples have been evaluated. It is found that the flower of Opuntia ficus-indica dye can be successfully used for the dyeing of cotton to obtain a wide range of colours by using various combinations of mordants.
