Influence of Dyeing Cotton with Reactive Dye on Adsorption of SilverInfluence of Dyeing Cotton with Reactive Dye on Adsorption of Silver

The influence of reactive dyeing on the silver adsorption of antimicrobial agent Ruco-Bac AGP on a cotton fabric was investigated for the research purpose. RucoBac AGP was applied on a cotton fabric using the exhaustion method. For a comparison, RucoBac AGP was applied on fabrics treated in a blank dyebath which contained all auxiliaries except for the dye. The quantity of silver, the antibacterial efficiency and wash-fastness were determined for functionalized fabrics. The whiteness and col our change of silver treated cotton fabrics were investigated as well. The research results show that dyeing with a reactive dye causes high er adsorption of silver on a bleached/mercerized cotton fabric and its antimicrobial efficiency. The changes in the whiteness and colour of the fabric are more visible when treating cotton with a higher concentration of RucoBac AGP.
