This paper extends the work of the first four parts of this series to apply the image analysis methods we have developed to characterize the fiber orientation of real nonwoven fabrics. The "real" fabrics chosen as typicla are a carded crimped fiber web, two relatively dense overal or area bonded fabrics, a pattern or ponit bonded spun-bonded-meltblown-spunbonded fabric, and a lightweight spunbonded nonwoven. In order to deal with real webs, it is necessary to develop a lighting system to give images with sufficient contrast along with an appropriate thresholding method to yield can characterize orientation reliably when a direct measrue is needed, and the information can be used to characterize and compre nonwoven laydown processes,
