Novel Azo dyes containing a hydrazide-hydrazone moiety for dyeing polyester fabric
Abstract Novel azo dyes containing a hydrazide-hydrazone moiety linked to the benzothiazole nucleus are synthesized effectively in this study. The primary purpose of the study was to identify the best dyeing parameters, such as shade, temperature, pH, and time, in order to better understand the beha...

| description | Abstract Novel azo dyes containing a hydrazide-hydrazone moiety linked to the benzothiazole nucleus are synthesized effectively in this study. The primary purpose of the study was to identify the best dyeing parameters, such as shade, temperature, pH, and time, in order to better understand the behaviour of dispersed dyes during polyester dyeing. To achieve excellent colour strength in value (K/S = 26), the ideal dyeing conditions for disperse dye 4 were 30 min, pH of 8, and 110 °C at shade 3%. While the ideal dyeing conditions for disperse dyes dye 10 and dye 11 were 30 min, pH of 2, and 130 °C at a shade of 3%. Depending on the coupler moieties, the coloured polyester samples ranged in hue from beige to dark brown. Furthermore, the impact of substituent’s was examined in relation to colour strength (K/S) measures and colourimetric coordinates (CIEL*a*b*) of dyed polyester fabrics. The synthesized dispersed dyes are good options for giving polyester textiles a variety of stable hues and very good colour strength as well as exceptional fastness to light, washing, and crocking. |
