A series of novel acid dyes, based on substituted aryl amines as diazo component and aminohydroxy-naphthalene sulfonic acid as coupling component were explored for their dyeing performance over nylon fabric. The dyes were applied on fabric by exhaust dyeing procedure and the resulting dyed fabrics were characterized for washing, light, perspiration and rubbing fastness properties. The results revealed excellent fixation, binding strength and fastness properties which indicate that the newly synthesized dyes are suitable for dyeing nylon fibers.
