Experiments to understand the effect of thermal point bonding on the properties of lightweight carded webs of two different fiber types have been carried out. The two fibers were Hercules T101, a conventional polypropylene fiber and Hercules T196, a new fiber which has been reported to have excellent point bonding performance. The work done included dynamic mechanical and tensile testing on small regions excised from the fabrics, as well as microscopy of the bonds and bond fringes.
