Enhanced antimicrobial coating on cotton and its impact on UV protection and physical characteristics

摘要: This research intends to enhance the antimicrobial activity of cotton fabrics coated with metallized TiO2-based colloids through integrating noble metals (Ag, Au) and silica in synthesis process. Colloids were synthesized a low-temperature sol–gel method applied surface at ambient temperature. Four molar ratios metal TiO2 (0.01, 0.1, 0.5 1%) used process elucidate impacts type concentration on fabrics. The property was studied monitoring growth reduction rate Escherichia coli (E. coli) bacterium dark. UV protection analyzed based ultraviolet factor (UPF) transmittance rates Moreover, impact coating mechanical characteristics examined changes fabric tensile strength air permeability. morphology elemental composition characterized using SEM images EDS analysis, respectively. It observed that presence significantly enhanced particularly for samples Ag-modified colloids. Also, showed positive negative UPF values fabrics, While fabrics’ improved, permeability decreased some extent after coating. role influencing parameters such as metals, silica, associated mechanisms discussed.
