| Abstract: | Poly(1,4-phenylene sulfide) (PPS) exhibits good dimensional stability and flame retardant characteristics but its commercial development as fibers is highly limited due to lesser dyeing and finishing characteristics. Hence in the present study, we focused on the anionic and cationic modifications of PPS to enhance its dyeing ability towards disperse, cationic, and anionic dyes. Novel sulfonation and chloromethylation-quaternization of PPS fiber were carried out to achieve an industrially viable dyeing process methodology. The chemically modified PPS fiber is dyed with disperse, cationic, and anionic dyes, and the dyeing adsorption efficiency is quantitatively studied using a dye-o-meter equipped with UV-visible absorption spectroscope. The ideal parameters for dye adsorption were determined as a function of dyeing time, material-toliquor ratio, dyeing temperature, carrier concentration, sulfonation, and chloromethylation. The fastness properties of the dyed fabrics were also studied. Overall, with a maximum dye uptake of 99 % and 90 % achieved for sulfonated PPS and quaternized PPS respectively, the optimized conditions can be readily scaled-up to the commercial dyeing of PPS fiber with disperse, anionic, and cationic dyes. |
