ResumoThe present study aimed to develop a dyeing process of cotton fabrics with natural onion skin extracts in order to obtain dyed fabrics with antimicrobial and anti-UV properties. The extract was characterized by LC-ESI-MS/MS and the antimicrobial activity of the extract was also evaluated. The dyeing process was optimized considering the influence of the temperature, pH and electrolytes. The effect of cotton pre-treatment with chitosan in the dye uptake was also evaluated. The dyed fabrics were characterized according to antimicrobial activity, anti-UV protection and fastness properties.
