In this study, sulfated β-cyclodextrin (S-β-CD) which is a β-cyclodextrin derivative was obtained by chemical treatment of natural β-cyclodextrin (β-CD) with sulfuric acid. Afterwards, β-CD and S-β-CD were applied to cotton fabrics. In different treatments, β-CD and S-β-CD were bonded to cotton fabrics with EDTA crosslinking agent. Then, all the fabrics were treated with antibacterial agent silver nanoparticles (AgNPs) and inclusion complexes were formed. The aims of this study were to increase the washing stability and the antibacterial activity against microorganisms and to compare the effects of β-CD complex and derivative complex with silver nanoparticles on treated cotton samples. So, for this purpose, the properties of the treated samples like antibacterial activity, washing stability, add-on, tensile strength, handle, thickness and color change were tested and compared to each other. In addition, characterization analyzes such as SEM, EDX and FT-IR were performed on the samples and XRD analysis was performed to characterize the AgNPs. As a result of the study, it was observed that AgNPs alone were not sufficient to obtain antibacterial textiles with strong antibacterial effect and good washing stability. The inclusion complexes formed with β-CD and S-β-CD had much more effective antibacterial activity and more robust washing stability. In addition, when the physical properties except stiffness and yellowness were considered besides antibacterial activity and washing stability, the treatment of derivative β-CD complex with AgNPs and crosslinking this complex to cotton sample by means of EDTA was found to be the most favorable method.
