Although many papers have been published on the mechanical properties of nonwoven fabrics, there is no report on the relationship between tensile and puncture properties. For the further application of lightweight nonwoven products in uses such as protective materials, the complete understanding of this relationship should be needed when they are subjected to puncture force. The objectives of this research are to assess the tensile properties with different tensile test methods and to compare the theoretical puncture force calculated by tensile property and experimental puncture force. In the our work, two test methods were used for the tensile properties: uniaxial and biaxial tests. The tensile strength of MD and CD direction. If the condition of tensile test was similar to puncture test, the test method would be in good agreement for predicting the puncture forces. A good correlation between calculated and experimental puncture forces was obtained in the order of biaxial, wide width strip, cut strip, and grab methods.
