In the present work, ortho-vanillin was used to produce an antibacterial multifunctional polyester woven fabric using a one-shot diffusion process with microwaves. Since the bio-based ortho-vanillin has a solubility parameter close to that of PET, it can diffuse inside polyester fibers. Two methods were investigated and compared to functionalizee polyester fabric with O.vanillin using diffusion processes: an exhaustion procedure at High Temperature and Pressure-HTHP with a liquor ratio LR 1/20 at 130°C and dip/microwave technique was used with LR 1/1 and varying radiation powers (125W, 250W, 450W) for 3 to 7 minutes.
