Abstract: 
Thermobonding is widely used in producing of nonwovens. In this study various ‎layers of thermobonded nonwovens were produced by altering the pressure, binder ‎fibers and quality of blending. Mechanical properties of the so-called layers such as ‎breaking strength and breaking elongation, bending rigidity and air permeability were ‎assessed consequently. The structure of the layers was then studied by scanning ‎electron microscope (SEM) and the interaction between the structure and mechanical ‎properties and failure mechanism of the layers was investigated. This study shows ‎that the interstructure appears in the form of point structure and agglomerate structure ‎when bicomponent PET and PP fibers were used as the binder respectively. The ‎detrimental effect of the interstructure on the mechanical behavior of layers was ‎spotted during the experiments. The results indicate that the magnitude of the ‎pressure, the type of the binder fiber and stages of blending affect the interstructure ‎enormously. SEM examination of the fractured ends of the layers after stretching ‎could assess the likely mechanism of failure of layers formed by bicomponent PET ‎binder and polypropylene binder fiber‏.‏
