Abstract: Natural dyes produce special aesthetic qualities which are environmentally friendly, add value to textile industry and helps in saving the environment from pollution. The scoured and bleached organic cotton hank was pretreated with myrobolan and dyed with Terminalia arjuna bark extract with varied dye concentration in different mordanting methods. The control and mordanted dyed cotton hanks were subjected to colour strength and colour fastness properties. Cotton yarn mordanted with Myrobolon+alum and Potash alum with 10 and 15 per cent dye concentration exhibited greater colour strength. The mordanted samples showed good to excellent (4/5) colour fastness to washing compared to control (4). Cotton yarn dyed through pre mordanting possessed excellent fastness properties than the simultaneous and post mordanting methods with light brown to dark brown shades. Thus, natural dyeing of Terminalia arjuna bark extract with organic cotton yarn is unique and new venture for the dyers, painters and fashion designers.
