摘　　要：熔喷是一种采用高温高速气流吹喷聚合物熔体形成微米级纤维的非织造工艺。近年来研究者已对纤维在熔喷工艺中的动力学机理进行了大量的理论和实验研究。而且最近亦有较多综述类文章对气流场分布规律、纤维细化机理、模头改进等研究进行了总结,却很少提到理论方程的演变和机理研究性实验的改进。因此,本文针对熔体在高温高速气流场中的动力学理论的发展进行了全面综述,并分析了气流场中纤维成形和网帘上纤维网沉积模型的演变。此外,还综述了纤维和纤维网成形机制的在线和离线探究实验。基于本文的综述将可为熔喷工艺优化、设备改进、纤维/纤网均匀性控制等方面提供理论依据和实验方案,从而进一步提高熔喷非织造产品质量。Melt blowing(MB)is a nonwoven fabrication process in which polymer melt is blown by hightemperature 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.
