ABSTRACT This study investigates the optical, mechanical, and antimicrobial properties of polypropylene (PP) fibers enhanced with titanium dioxide (TiO 2 ) zinc oxide (ZnO) nanoparticles. Using a Mach–Zehnder interferometric system, we examined refractive indices, birefringence, opto‐mechanical behavior blank PP, PP/TiO , PP/ZnO nanocomposite under various conditions, including different polarization orientations during cold drawing processes. The 2D Fourier transform algorithm is employed to analyze data, enabling precise measurements index profiles birefringence. Results show that both TiO ZnO nanoparticles significantly enhance optical mechanical PP fibers. exhibited highest (1.530) birefringence (0.0459), followed by (1.522 0.040) (1.520 0.031). maximum draw ratios achieved were 4.2, 3.9, 3.5 for PP/ZnO, fibers, respectively, indicating improved in nanocomposites. Antimicrobial efficacy was evaluated using shaking flask method density against Escherichia coli Staphylococcus aureus Pseudomonas aeruginosa Candida albicans . demonstrated activity, growth reductions ranging from 64.8% 80.4%, PP/TiO2 (56.0% 70.3%).
