Disperse dyes con anello tiazolico per la colorazione di tessuti e fibre naturali e sintetiche

In this experimental work, a comparative study on the dyeing ability of a series of thiazole-based azo compounds on different synthetic and natural fibers was performed. The azo compounds were synthesized starting from 2-aminothiazoles substituted, or not, at position 4, and tetrafluoroborate aryldiazonium salts. They have been applied as disperse dyes for the dyeing of synthetic and natural textiles and fibers. The staining process was carried out under different conditions and the color of each sample was measured using the CIELab system. The influence of pH, dispersing agents and washing resistance were assessed. The most satisfactory results were obtained for the textiles of acetate, polyamide and silk.
