A high-speed camera was used to record the motion of a fiber below both a melt-blowing slot die and amelt-blowing swirl die. These recorded images were processed to determine the frequency and amplitude offiber motion during melt blowing. The operating variables investigated included polymer flow rate, air flowrate, polymer temperature, and air temperature. A crossover counting method was developed to determinethe frequency of fiber motion. The frequencies determined from this counting method favorably comparedwith frequencies determined by taking fast Fourier transforms of the fiber displacement data. Experimentalresults for frequency and amplitude were compared to predictions from a three-dimensional mathematicalmodel for the melt-blowing process.
