Cotton and polyester fabrics are among the important textile materials used for various purposes most especially in clothing. The fabrics are increasingly dyed with synthetic dyes which in most cases appears hazardous to the wearers and those engaged in the dyeing operations. In the present study, dyes were extracted from three varieties of kola nuts (Red, white and bitter) and applied to cotton and polyester fabrics. Three mordanting techniques (pre, simultaneous and post mordanting) were adopted in all the dyeing. The fastness properties of the dyed fabrics were evaluated. The result of these assessments reveals that dyeing carried out with simultaneous mordanting produces the best result of all round fastness properties (wash, light, perspiration and pressing) with red kola dye extract. The result, further reveals the viability of the colouring object from red kola and when properly investigated could serve as a possible substitute to hazardous synthetic dyes that remain a serious threat to the environment.
