Arylene bisazo resorcinol dyes IIIa-e were prepared and polycondensed with formaldehyde in the presence of aqueous oxalic acid. The resulting polymeric dyes IVa-e were characterized by yield, melting point, colour, elemental analysis and visible and IR spectroscopy. The thermal properties of polymeric dyes were examined by thermogravimetric analysis. Their dyeing performance on nylon and polyester was assessed. The dyeing on nylon and polyester had yellow, orange, red and brown shades with moderate to good, light and wash fastness. Polymerization of bisazo dyes IIIa-e with formaldehyde on dyed nylon and polyester have also been carried out. The dyeing properties of polymeric dyes were compared with the dyes polymerized on nylon and polyester. |
