DYEING OF ANTIBACTERIAL FINISHED WOOL FABRIC USING Ag/TiO2 NANOCOMPOSITE PARTICLES

Ag/TiO2 nanocomposite were prepared through chemical reduction method and characterized by XRD to examine its formation. Transmission Electron Microscope (TEM) was used to evaluate its particle size and size distribution. The wool fabric was treated with Ag/TiO2 nanocomposite then dyed with CI. Acid Orange 74 (AO74). The Ag/TiO2 nanocomposite pre-dye uptake was compared to conventional dyeing of wool. The existence of Ag/TiO2 nanocomposite on wool fabric during acid dyeing increases the dye uptake. The dyeing kinetic of wool fabric was positively affected by treating with the nanocomposite. Also, the activation energy of AO74 diffusion was calculated before and after the treatment. The Ag/TiO2 nanocomposite-treatment leads to produce a wool fabric with excellent antibacterial and photocatalytic properties. Ag/TiO2 nanocomposite-treatment has no adverse effects on fastness properties of the functionalized dyed wool fabric
