Characterization on pore size of honeycomb-patterned micro-porous PET fibers using image processing techniques

This paper presents a method to characterize the pore structure of the fibre surface for the honeycomb-patterned PET fibers, by using a scanning electron microscopy (SEM) and image processing techniques. They consist of linear channel pores (LCP) and ellipse pores (EP) surface pore distribution and micropore numbers varied from each fiber to another, which can make significant differences on the property, of the spun yarns. It is proposed that the fiber should be sufficiently rinsed with clean water before dewatering and setting processes, to eliminate the pore-clogging effect.
