Efficient coverage of ZnO nanoparticles on cotton fibres for antibacterial finishing using a rapid and low cost in situ synthesis

Abstract

Zinc oxide nanoparticles (ZnONPs) have received considerable attention as antibacterial agent, particularly in textile industry. In the present work, a successful procedure for in situ growth of ZnONPs in textiles was developed. Results obtained showed that the combination between in situ synthesis and sol-gel method promoted a uniform and dense adsorption of the nanoparticles both inside and on the surface of fabric fibres. The fabrics finished with ZnONPs have been investigated from antibacterial properties by the agar diffusion method and by the absorption method according to ISO 20743: 2013 standard and exhibited antibacterial effect against methicillin resistant Staphylococcus aureus ATCC33591, Staphylococcus epidermidis ATCC1228, Staphylococcus aureus RN4220 and Propionibacterium acnes ATCC6919. Moreover, tests conducted with hydrogen peroxide suggested the involvement of reactive oxygen species, namely the involvement of hydrogen peroxide, in the antibacterial activity of zinc oxide nanoparticles. Therefore, synthesised nanoparticles showed great potential to be used as coatings for medical, cosmetic or sports fabrics.
