This paper reports about cotton textile modification by sol-gel technology with the purpose of obtaining antibacterial properties, evaluation of antibacterial properties and dermal toxicity tests of cotton textile with Zn and Si coating. Antibacterial properties evaluation against pathogenic microorganisms Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli made using the Parallel streak method in accordance with ATCC147 standard. For more specific evaluation of the coated textile, in vitro cytotoxicity test with epidermal HaCat cells was done. It is concluded that the coatings containing Zn and Si obtained by the sol-gel technology can impart antibacterial properties against pathogenic bacteria to the textile by preventing the bacteria from growing; strong inhibition of growth was detected for all test microorganisms. Based on the dermal toxicity test results, it is not expected that the prolonged contact of the skin with coated textiles will have a negative impact on the skin tissue – epidermis.
