Abstract

J.O. Otutu

Six disazo disperse dyes derived from 2-Methoxy-5-nitroaniline and 3-chloroaniline were synthesized in good yield. The results of the absorption spectra of the dyes show that the dyes exhibited good colour yield. The dyes were characterized by spectral methods. The UV-vis spectral data has also been discussed in terms of structural property relationship. The dyeing assessment of the synthesized dyes was evaluated on polyester and nylon 66 fabrics. The results showed better hue with good colour fastness to washing, rubbing and light. The absorption spectra also show that the dyes have very high tinctoral strength and may act as organic photoconductors.
