Two water based disperse inkjet inks for polyester textile printing with antibacterial properties were prepared. The antibacterial activity was due to the presence of polyhexamethylene bisguanidine (PHMBG). The surface tension, pH, viscosity and conductivity of all inks formulations were monitored over a period of time for the evaluation of ink stability and suitability. The inks were used for application on polyester and polyamide samples by exhaustion (dyeing) and wash, light fastness and colour measurements were made on the dyed samples. The optimum application level required to give long lasting antimicrobial protection was determined by carrying out a series of antimicrobial testing.
