The effect of sodium poly (styrene sulfonate) (PS) on acid dyeing of nylon with C. I. Orange 7 was investigated. Sodium ethylbenzene sulfonate (EB) was used for comparison. Both of PS and EB is found to be effective as retardant of acid dyeing of nylon. The retarding effect of EB is more remarkable than one of PS. PS is adsorbed only on the surface of nylon due to the large molecular size, while EB is diffused into the nylon substrate. A model of nylon dyeing in the presence of PS or EB is presented.
