Nonwoven may be digitized by two methods: as images taken from real media, or as generated computer representations obtained from average properties of real media (porosity, fiber diameters, and fiber orientation). Given an accurate correlation between reality and the computer representation of nonwoven, the use of generated media can accelerate the search for potential improvements. We discuss the computer simulation of mercury intrusion porosimetry by the pore morphology method, and present some examples. Through the pore morphology method, it is possible to establish links between production parameters like grammage and fiber diameters, and the porosimetry measurements. Real media experiments would require more effort, cost and time. Automation of the procedure, from fiber generation to property computation, allows deriving analytic formulas for pore size measures depending on production parameters.
