Design of Photodynamic Antibacterial Cotton/Camel Hair Textiles via Rose Bengal Functionalization

The study successfully developed photodynamic antibacterial camel hair textiles by functionalizing camel hair with the photosensitizer Rose Bengal (RB), achieving significant antibacterial efficacy against Staphylococcus aureus and Escherichia coli under visible light. The RB-modified camel hair demonstrated 99.99% inactivation of S. aureus and 99.65% of E. coli within 30 minutes of light exposure. Blended yarns of camel hair and RB-camel hair exhibited strong mechanical properties, with maximum tensile strengths of 4.02 MPa and 5.82 MPa for 70:30 camel hair/RB-camel hair and 70:30 cotton/RB-camel hair blends, respectively. The study highlights the potential for high-value, diversified development of camel hair textiles with enhanced antibacterial properties.
