The constituents of some selected local plants: Red Baphia nitida (BN1) and yellow Baphia nitida (BN2) camwood; Curcuma lunga known as turmeric (CL) and Tectona grandis known as teak leaves (TG) from Abakaliki were extracted using aqueous and organic solvents: distilled water, methanol and chloroform. The residues of the different extraction solvents were labeled BN1A and BN2A for aqueous extracts; BN1C and BN2C for chloroform extracts and BN1M and BN2M for methanol extracts respectively. The Cucuma lunga extracts were labeled CLA, CLC and CLM for aqueous, chloroform and methanol solvents respectively while Tectonia grandis TGA, TGC and TGM extracts were labeled according to the solvent used in the extraction. These extracts were used in their crude form to dye cotton and polyester fabrics; the cotton was used as a natural fiber and the polyester was used as a synthetic fiber. The fabrics when dyed with the extracts showed different colours but exhibited poor dyeing properties. These fresh were mordanted with metals salts such as CuSO4, FeCl3, SnCl2 and K2Cr2O7 and dyed with fresh samples of the extracts. These mordanted fabrics showed different colours were fast to wash, alkali and acid.
