%X This study aims to explore the essential functional requirements associated with controlling the proliferation of microbes in the domain of textiles used in public health areas. Herein, three antimicrobial agents, specifically iodopropylbutylcarbamate (IPBC), 1-hydroxypyridine-2-thioketone zinc (ZPT), and 2-octyl-3-isothiazolinone (OIT), were chosen for fabric finishing based on their notable effectiveness, minimal toxicity, cost-efficiency, and chemical stability. Utilizing Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) as representative bacterial strains, the Minimum Inhibitory Concentration (MIC50) of individual and combined antimicrobial agents was measured, and their antimicrobial effectiveness was rigorously evaluated. Concurrently, the antimicrobial effectiveness, whiteness, and mechanical durability of the fabric following antimicrobial treatment were thoroughly examined. The results demonstrate that some combinations of the three antimicrobial agents elicit additive effects on both S. aureus and E. coli. Notably, at an equivalent ratio of IPBC, ZPT, and OIT and a total concentration of 0.2 wt. %, the inhibition rates against both bacterial strains surpass 99%. Upon application to nylon fabric, the treated material demonstrates significant antimicrobial properties, with minimal reduction observed in the whiteness and tensile strength of the treated nylon. This study provides practicable strategies relevant to the production of textiles endowed with antimicrobial properties.
