Cationic retarders utilized in the dyeing of acrylic fibers have been considered to act as colorless dyes by blocking dyesites and hence moderating the rate of dye uptake during the critical initial stages of the dyeing of acrylic fibers. By studying the rate of exhaustion of selected retarders concurrently with the rate of exhaustion of several cationic dyes, a novel classification scheme for the behavior of retarders has been arrived at. Utilization of the herein defined CR value for retarders allows intelligent choice of retarder prior to dyeing without having to resort to empirical methods which are often costly and lacking in accuracy. The overall activity of cationic retarders such as quaternary ammonium compounds bas been found to be dependent upon the structure of the alkyl or aryl side chains. The relationship between retarder structure and its activity or compatibility behavior is discussed.
