Abstract
The present paper deals with the application of natural dyes extracted from cassia fistula fruit or golden shower tree seed pods on nylon fabric. The dyeing properties were evaluated by measuring K/S and CIELAB values. In addition, the different fastness properties were evaluated. The effect of metal mordants at different concentration levels with respect to their colour strength was also studied. Nylon fabrics dyed with golden shower tree seed pods extract without mordant showed a light brownish-yellow shade, while those dyed with ferrous sulfate and stannous chloride brighter brownish-yellow colour. Nylon substate dyed with alum and CuSO4 gave a duller brownish-yellow colour. The fastness properties ranged from fair to good level.
