Development and Evaluation of a Biaxial Tensile Tester for Fabrics



At the Nonwovens Cooperative Research Center (NCRC), North Carolina State University, a prototype instrument has been designed to measure fabric behavior under biaxial force. The system is equipped with a segmented and self-adjusting clamping system designed to apply uniform finite strain in the sample without undesirable boundary effects. The control system is designed to allow tests to be performed under a constant force-ratio or a constant extension-ratio condition. The designs of the clamping and control systems of the instrument have been evaluated by testing a number of spunbonded nonwoven fabrics. The results show a significant influence of biaxial deformation on the force-extension characteristics of fabrics.
