In this research, different concentrations of PAN polymeric solutions with various percentages of TiO2 nanoparticles were electrospun to investigate vertical wicking of PAN/TiO2 nanofiber yarns. Results showed by the presence of nanoparticles in the nanofiber structure, the capillary rise increased, although by increasing concentrations of polymeric solutions and nanoparticles, capillary rises were statistically insignificant
