Abstract :
Staphylococcus aureus and Pseudomonas aeruginosa are pathogenic, opportunistic bacteria that are often transmitted to skin lesions and wounds through contaminated sheets, utensils, and staff in hospitals. Therefore, using fabrics with antimicrobial properties in such environments decreases the chances of contamination.In this study, a polyester/viscose fabric was immersed in fluorocarbon (FC) and gentamicin (GC) to investigate their antibacterial effect against Staphylococcus aureus and Pseudomonas aeruginosa. Additionally, the waterproof and blood-resistance characteristics of the samples were evaluated. Concentrations of 1.25, 2.,5, and 5 g/l of gentamicin and 60, 80, and 100 g/l of fluorocarbons were used for the polyester/viscose fabric immersion using the spray method. After treating the fabrics with gentamicin and fluorocarbon, they were heated at 180°C for 3 minutes for further stabilization.The agar disk diffusion method was used to investigate the inhibitory effect of fluorocarbons and gentamicin on the growth of the aforementioned bacteria and the results were recorded after 24 hours. The durability of the antibacterial effect was investigated by transferring the discs to a regrowth culture once more and keeping them there for 24, 48, and 72 hours. 1.25 g/l of gentamicin and 60 g/l of fluorocarbons had the least inhibitory effect against the bacteria. The best durability of the antibacterial effect resulted after 2 consecutive treatments. Moreover, 60 g/l of fluorocarbon exhibited the best waterproof and blood-resistance effects.
