Overview of the Fiber Dynamics during Melt Blowing

Melt blowing (MB) is an industrial process used in producing microfibrous nonwoven materials. Over the past decades, a considerable amount of theoretical and experimental research has been conducted on the mechanisms of fiber dynamics during MB. Although some studies have been summarized by recently published review articles, the evolution of the theoretical equations and improvements in the experiments are rarely mentioned. Therefore, this work presents a comprehensive overview of the research on fiber dynamics, especially on the evolution of its theories. For the theoretical aspect, the evolution of the fiber formation and the fibrous web formation models were analyzed. In addition, online and offline experiments were used to demonstrate fiber formation and fibrous web mechanisms. The fundamental studies reviewed in this paper contributed noteworthy findings in controlling the fiber and web quality, thereby improving the product behavior during MB.
