Diallyl dimethyl ammonium chloride (DMDAAC) is very popular cationic monomer that is used to synthesize color-fixing agent. But this kind of fixing agent has some drawbacks. This paper reports to minimize those drawbacks by co-polymerizing with N,N-dimethylamylamine (DMAA). The effect was studied by varying the amount of DMAA with respect to main monomer DMDAAC. Also the effect of APS was observed on the polymer properties. The best polymer was found with DMDAAC and DMAA 61% and 1% respectively where the amount of APS was 0.5%. The synthesized agents were applied according to the industrial procedure on cotton woven fabric dyed with reactive dye. Color fastness to wash, color fastness to dry wet rub, change in K/S, lightness DE and overall color differences DE were observed to evaluate the synthesized agents
