The importance of nonwoven filter media is increasing since they are versatile and economic at the same time. Approximately two-thirds of the nonwoven filters comprised by polymeric fibers are formed by spunbond or meltblown processes. The quality of the spundbond or meltblown production process immediately influences the filter media quality. At the Fraunhofer ITWM we developed a simulation tool that assists engineers to simulate and in particular to optimize the process in order to gain a better homogeneity of the filter media. We present the underlying models, simulation algorithms, and the simulation tool FIDYST (Fiber Dynamics Simulation Tool) with industrial applications for filter media production.
