To prevent possible spread of nosocomial infections - HAI (Healthcare Acquired Infections) in healthcare facilities, Antibacterial textiles are developed. This carried out study has been conducted to assess the feasibility of the method of obtaining antibacterial coatings on textile materials. Specifically, the sol-gel method for synthesis of titanium dioxide nanoparticles in combination with zinc oxide nanoparticles from titanyl sulphate and zinc nitrate hexahydrate has been investigated. During the synthesis of titanium dioxide nanoparticles in combination with the zinc oxide nanoparticles, the coated textile material showed stable antibacterial properties with a suppression level ofEscherichia coliof more than 99.99%. The method has been tested on a semi-industrial scale in roll-to-roll experimentby applying homogenous coatings at a speed of 1,5 m per minute.

• Degradation of BPA by high-pressure hydrodynamic cavitation. • Degradation with smaller nozzle needs 30% less power for the same result. • Bubble sizes measured in reactor. • Smaller bubbles in the reactor leads to a more efficient degradation. • Correlation of jet length, chemiluminescence, power input and BPA degradation.
