The effect of the alkyl chain length of dialkyldimethylammonium bromide (dad-mab) on disperse dyeing of nylon 6 fibers is investigated. Both dyeing rate and saturation value of 1,4-diaminoanthraquinone (1,4-daa) improve with decreasing alkyl chain length of dadmab, dadmab does not lower the glass transition temperature T g of nylon 6. The apparent solubility of 1,4-daa increases with increasing alkyl chain length of dadmab, but the adsorption of dadmab on nylon 6 fibers decreases with its increasing alkyl chain length. It is likely that the interaction of dadmab with nylon 6 or with the dye influences the dyeing properties of the fibers.
