Fibers, Filters and Membranes
The performance evaluation of a filter or a membrane often requires the characterization of fiber thickness and through-pores size. ALFATESTLab is equipped for these measurements thanks to a scanning electron microscope SEM coupled to a unique software called Fibermetric for automatic measurement of fiber thickness, and to various techniques for pore size distribution measurements.
In many industries, fibers are used according to their applications properties: for instance, fibers with high mechanical properties are used to reinforce materials, unlike those used in textile or medical fields. The choice of fibers material can then be guided by a rheological characterization, GPC and Light Scattering measurements, and subsequent evaluation of fibers can be performed with automated image sistem (Morphologi G3 from Malvern Instruments also uses a shape parameter dedicated to the fibers characterization).
