Abstract
This manuscript aimed to improve the ignition, mechanical properties and antibacterial activity of polyester fabric irradiated with UV/Ozone (for 30 minutes) after coated with sol-solution and pomegranate rind natural dye (PRND). Phenyltrimethoxysilane (PTMS) was used to form siloxane bonds as the main chain of the sol coating. The effect of (PRND) concentration was studied. The Fourier transform infrared (FTIR), illustrated the inter-chemical reaction between (-OH) groups in sol-solution with the free radical on the irradiated polyester fabric. Adding different amounts of PRND during solsolution synthesis, lead to increase reduction percent of gram-negative (E. coli) and gram-positive (S. aureus) bacteria and improve the thermal and mechanical properties with no flame retardancy effect. The flame chamber (UL/94), limiting oxygen index (LOI), and EN ISO 11925 tests were used to investigate the ignition properties of the treated and untreated specimens.
