What changes occur in the fiber structure when the angle of the Meltblown die outlet blower air is changed?

02 January 2021 1 4K Report

Blower compressed air given at the Meltblown die outlet generally pressurizes the polymer melt at an angle of 60 degrees. What changes occur in the fiber structure when this angle is changed? As is known, submicron fibers provide advantages for filtration and acoustic insulation surfaces. What is the significance of this angle in question?
