Spinning processes like spunbond or meltblown result in stochastic filter media with a level of heterogeneity depending on the process parameters. This presentation deals with a study of the performance of a filter depending on the heterogeneity of manufactured filter media.

First, we shortly discuss the modeling and simulation of the filter media manufacturing process and the parameters describing the heterogeneity of the manufactured media. The superposition of thousands of filaments to the nonwoven web is characterized with only few parameters describing their laydown spread and its local curling. The result of the simulation performed at the previous stage is...
