For textile materials, tensile properties have remarkable time effect due to their visco-elasticity. There are several methods for measuring or evaluating them, but the results are largely depend on the methods used and conditions under which the test is conducted. In this paper, the general methods of measurement and evaluation of textile materials under cyclic deformation at low frequency and large deformation (7.44%) are described. Since the ordinary visco-elastic laws can not be applied to such large deformation, only qualitative evaluation on real textile materials is possible under those conditions.
