Paper Abstract

The aim of this study is to characterize the surface of thermobonded nonwovens which can be used as surgical gowns or caps in medical applications. These nonwovens consist of nets of polypropylene fibers which are more or less randomly tangled and the cohesion of this surface comes from its manufacturing process through the bonding points. The tactile feel of the consumer is known to depend on the structure of the surface, hence it will be deeply studied. We consider degree of polarization images of the samples. Firstly the bonding points of a calendered nonwoven are detected using the degree of polarization of the light reflected by the sample under polarized incidence and two sets of the same nonwoven are differentiated through the analysis of their bonding points and of their fibrous part. We show that the degree of polarization of the bonding points is linked to the intensity of the manufacturing process. The second part is about the fibrous part of the nonwovens, studied in order to determine the main orientation of the fibers.
