Abstract
An aqueous dye composition is based upon a mixture of a water-soluble titanium salt, preferably titanium potassium oxalate and a tannin substance, preferably Myrobalan extract. This dye composition may be used to dye either natural fibers, synthetic fibers or blends thereof. The composition is particularly advantageous for either bottom dyeing denim fabric which can then be overdyed with indigo blue dye to provide blue-green hues or as a mordant for a basic dye.
