The introduced hydrophobic cavities had the ability to form inclusion complexes with both the disperse dye molecules and the selected antibacterial agents namely triclosan derivative, Invasan®, and hyperbranched poly (amid amine) loaded with nano silver, HBPAA/AgNPs composite, in subsequent disperse dyeing and functional finishing respectively. The obtained results revealed that chemical modification of wool/polyester structure using MCT- βCD (20g/L), followed by post-printing, and functional finishing with the nominated active ingredients, triclosan (10g/L) and AgNPs/HBPAA hybrid solution (10g/L) result in a significant improvement in the depth of the obtained disperse prints along with a noticeable increase in the imparted antibacterial functionality against the tested harmful pathogens namely Gram-positive (G+ve: S. aureus) and Gram-negative (G-ve: E. coli) bacteria. On the other hand, the SEM and EDX analysis has confirmed both the deposition of MCT- βCD onto the fabric surface as well as immobilization and fixation of the used bioactive agents.
