The Effect of Air Pressure on the Evolution of Fiber Path in Melt-Blowing Process

Melt blowing is an important method for producing ultrafine fibers. In melt blowing process, compared to the studies on the fiber path at a certain air pressure condition, much less has been done on searching the evolution of the fiber paths at different air pressures. In this study, a high-speed camera was used to capture the fiber paths below a slot die and a swirl die in the melt-blowing process. The evolution of the fiber paths was captured. This paper first shows the evolution of the fiber paths at different air pressures, which is useful to further understand the attenuation effect on the fiber in the melt-blowing process.
