摘要
An air drawing model of a polymer in a melt blowing process is presented and solved by introducing the numerical computation results of the air jet flow field of the dual slot die. The model';s prediction of fiber diameter tallies well with the experimental data. The effects of processing and die design parameters on fiber diameter are discussed. A lower polymer flow rate, higher initial polymer temperature, higher initial air velocity, higher initial air temperature, smaller angle between the slot and the spinneret axis, smaller width of the die head, and larger width of the slot can all yield finer fibers.
