Abstract

Theoretical and experimental studies of the technology of blown spinning of nanofibers from a polyacrylonitrile solution for the production of nonwovens are presented. Numerical simulation of air spray flows in the coaxial nozzle and their interaction with a polymer solution is given. A model is developed to further optimize the parameters and scale the production of nanofiber materials. The mathematical model allows determining the distribution of air flow rate throughout the workspace that affects the diameter and structure of the fibers and visualizing the process of transformation of a drop of polymer solution into a thin thread, providing insights into the stages of fiber formation. The experimental studies produced nanofibers with an average diameter of 237 nm.
