Melt blowing is a one-step approach for manufacturing microfibrous nonwovens. In slot-die melt blowing, a pair of air jets with high velocity and temperature is applied on the polymer and attenuates the polymer in to fibers. The fiber motion which was called vibration or whipping plays a crucial role in expressing the drag mechanism. In this study, an improved Lagrangian numerical approach was utilized...
Melt blowing is a major process for producing nanofibrous nonwovens. Compared to another technology for producing nanofibrous nonwovens, electrospinning, melt blowing applies high-speed air flow field to attenuate the extruded polymer jet. It is known that the essential electrospinning mechanism is a rapidly whipping jet in an electric field. While there are few studies on the fiber whipping in the...
