The mechanical properties for mechanically punched N.W. fabrics could be represented by high degree of accuracy by using mechanical model or equivalent electric model. The mechanical models are composed from elements that differ in number and order (or arrangement) according to the properties to be represented and are often a spring to describe complete elasticity and a dash pot to describe the complete plasticity. In the present work given the relationships are given to be used for the conversion from mechanical models to electric models, because the analysis of electric circuits is always as much easier than that of equivalent mechanical models, The results obtained in this work for N.W. fabrics proved that the stress-strain relationship is not sufficient enough to describe the mechanical behaviour of these fabrics, therefore it is necessary to study the effect of time, this is what known as creep, then its behaviour is measured after unloading this is known as relaxation.
