Overview of the Fiber Dynamics and Experiment in the Melt Blowing
Melt blowing(MB)is a nonwoven fabrication process in which polymer melt is blown by high-temperature and high-speed air to form micro-nano fibers.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 involving air flow field distribution,fiber thinning mechanism,and die improvement have been summarized by recently published review articles,the evolution of the theoretical equations and improvements in the mechanism experiments are rarely mentioned.Therefore,this work presents a comprehensive overview of the research on fiber dynamics in high-temperature and high-speed air.The evolution of the fiber formation and fibrous web formation models were analyzed.In addition,online and offline experiments used to demonstrate fiber formation and fibrous web mechanisms also are reviewed in our work.The fundamental studies reviewed in this paper contributed noteworthy findings in controlling the fiber and web uniformity,improving MB instrument and process,thereby enhancing the MB product quality.
