Bond Structure and Tensile Properties of ...

Extensive studies have been conducted to investigate the effect of several process conditions on the structure and properties of nonwoven webs. As thermal point bonding is one of the most important processes, a detailed analysis of the point bond structures was done to help understand the development of tensile properties. Spunbond fabrics produced under different conditions were investigated, especially with respect to bond structure and failure mechanisms. Although bond structure does not show a big difference on microscopic observation, the way it responds during tensile deformation is dissimilar depending on the bonding temperature, leading to differences in failure mechanisms and tensile properties of the web.
