Gram-Positive and Gram-Negative Antibacterial Activity in Textiles Impregnated with OA-g-CSO Copolymer

Antibacterial textiles impregnated with chitosan copolymer (OA-g-CSO) have shown good antimicrobial performance and are resistant to different strains by inhibiting the growth of bacteria. However, the partial performance of these antibacterial textiles against Gram-positive and Gram-negative strains has not been well evaluated. In this research, two types of OA-g-CSO copolymers with different precursor ratios were prepared, in which the minimum amount of amino substitution was considered to show antibacterial properties on textiles. The performance of these two types of copolymers on textiles was evaluated by examining the time effect of textiles impregnation with OA-g-CSO, the maximum retention time of the OA-g-CSO emulsion, and the detergent effect on the antibacterial textiles.
