    Multifunctional textiles have been widely investigated with antimicrobial, self-cleaning, UV-protective properties, etc. Especially sol-gel coating doped with bioactive agents and special agents provides to produce multifunctional textiles. In this study, dip-coating (pad-dry) and solvothermal (exhaustion) sol-gel processes were used for coating of cotton fabric with silica and titania sols to achieve the properties mentioned above. A quaternary ammonium salt and silver salts as antimicrobial doping agent were embedded in titania sols with or without silica. Antimicrobial properties against Staphylococcus aureus (S. aureus) of the coated fabrics were characterized. The effect of precursors, doping agents and different sol-gel processes were also compared on performance properties of the fabric samples.
