A sol-gel method for applying nanosized antibacterial particles to the surface of textile materials in an ultrasonic field

Abstract 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 of Escherichia coli of more than 99.99%. The method has been tested on a semi-industrial scale in roll-to-roll experiment by applying homogenous coatings at a speed of 1,5 m per minute.
