摘要：A renewed international interest has arisen in natural dyes due to increased awareness of the environmental and health hazards associated with the synthesis, processing and use of synthetic dyes. The present investigation was carried out to extract natural dye from Callistemon citrinus plant. The dye was extracted by boiling method. A part of the extract was autoclaved. Both the autoclaved and non-autoclaved Callistemon citrinus flower dye was used for dying the scoured cotton cloth using two mordants viz. Copper sulphate and ferrous sulphate. Study about fastness tests of dyed clothes was undertaken. The relative colour strength of the dye was determined in terms of K/S value with respect to autoclaved and non-autoclaved extract. Good light fastness, rub fastness and wash fastness was observed in fabrics mordanted with ferrous sulphate. The relative colour strength of the dye was found to be more in case of cotton clothes mordanted with ferrous sulphate.
