Thermally bonded structures are amongst the most widely used nonwoven structures, with
applications ranging from baby diapers to high performance geotextiles. These structures
undergo various modes of deformation during their performance. In this study, the
mechanical properties namely, tension, shear, bending and compression of thermal bonded
polyester fabrics, have been investigated, including directional dependence of the tensile
and bending tests, revealing anisotropic characteristics. In addition, the fiber orientation
distribution was determined using two-dimensional (2D) image analysis of fabric cross-
sections, a technique that is generally used for measuring fiber orientation in short-fiber
reinforced composites. The ambiguities, errors and corrections employed in the
measurements of fiber orientation are discussed. The initial tensile response of thermal
bonded nonwovens has been predicted and compared with the experimental stress-strain
curves obtained in various test directions. Bending and compression measurements were
done on KES-F and shear measurements were carried out using picture frame test up to a
shear angle of 45°.
