Abstract

Silver ions were added to β-cyclodextrin-grafted organic cotton to create antibacterial fabrics that are more effective and long-lasting. In the presence of sodium hypophosphite, citric acid was used as a cross-linker to graft β-cyclodextrin onto the fabric, cementing the structure for ten minutes at 150°C. The presence of silver ions on the grafted fabric was verified by UV-visible and FTIR spectral studies of β-cyclodextrin, β-cyclodextrin-grafted fabric, ungrafted fabric, silver ions, and silver ion-loaded fabric. Using ethanol, silver ions were removed from both grafted and ungrafted fabrics. They were then measured using high-performance liquid chromatography (HPLC) analysis, which showed that the grafted fabric had a noticeably higher concentration. Using the agar diffusion method, silver ionloaded ungrafted and grafted textiles were evaluated against Staphylococcus aureus and Escherichia coli; E. coli showed a more noticeable inhibition. Compared to the ungrafted fabric, the grafted fabric’s antibacterial agent showed better inhibition and persistence, maintaining its efficacy even after ten wash cycles. A long-lasting antibacterial textile was created by grafting cyclodextrin onto the cloth and adding silver ions to its cavity.

Keywords: Cyclodextrin, Citric acid, sodium hypophosphite, silver ions, antibacterial textile, organic cotton.
