dc.description.abstractSynthesis and application of squarylium dyes has been undertaken in order to characterise the synthesised dyes by different spectrometric techniques, (FT-IR, UVvisible and GC–MS), and to study their fastness properties, such as wash, light, perspiration, and hot pressing, on nylon 6 and polyester fabrics. Also, effects of time, temperature, carrier concentration and pH was investigated on polyester and nylon 6 fabrics. The dyed fabrics were generally found to show good (4) to very good wash (5), light fastness of (5) and (6), perspiration (4) and (5), hot pressing (4) and (5) on nylon 6 and good to very good on polyester fabric respectively. The dye-bath exhaustion was found to be between 76 % and 92 % on nylon 6 and 57 % and 85 % on polyester respectively. The percentage exhaustion on nylon 6 was found to be very good to excellent and but on polyester it was found to be good to very good. It can be concluded that squarylium dyes can be applied to nylon 6 and polyester fabrics, but better performance was found on nylon 6 than polyester fabric due to the amorphous nature of nylon 6 compared to polyester.en_US
