Effect of dye sulphonation on the dyeing of nylon, 6, 6 WITH 1-hydroxy-2-phenylazo-6-[2-chloro-4-[phenylamino] triazin-6- ylamino] naphthalene-3-sulphonic acid reactive dye

Abstract

The study investigated the synthesis of monofunctional reactive triazinyl dye, base in a particular chromophore and possess a single chlorotriazinyl reactive group and the dyeing behavior evaluated on nylon 6, 6 fabrics. It was found that percentage exhaustion of the dye on nylon fibre increased with decreased pH application due to sulphonation.
