Abstract
The synthesis of some disperse dyes base on anthraquinone was achieved by coupling diazotised 1-aminoanthraquinone and tetrazotised 1,4-diaminoanthraquinone respectively with pyridone derivatives. The identity of the resultant dyes were investigated using UV-visiblespectrophotometry, Fourier Transform – Infra Red and the relative molecular mass of the intermediates were confirmed using mass spectrometry. The applications of these dyes to polylactide fabrics were also studied. The results obtained indicated that the monoazo dyes exhausted better than the disazo dyes on polylactide fabrics. The fastness properties to washing, perspiration, sublimation and light were observed to be good to very good for all the dyed polylactide fabrics.
