Nanofiber is a material that has broad potential applications. However, the application of nanofibers in the industry is still facing the problem of increasing production rates. Rotary force spinning (RFS) is a method that is still being developed to produce nanofibers relying on centrifugal force, and it is claimed to have a high production rate and employs relatively simple instruments. To investigate the performance of the RFS, we examined the effect of the angular speed and the spinning solution properties on the morphology of rotary force-spun PVP nanofiber. The PVP concentration explicitly affects the density and viscosity of the spinning solution. Increasing the concentration of PVP in fiber production using the RFS will produce fibers with a larger diameter. While increasing the angular speed, the diameter of the fiber will decrease. The fibers obtained had a smooth morphology without beads. Therefore, the RFS used in this study can be utilized in developing nanofibers for various applications. © 2025 Author(s).
