We developed a fatiguing system that is capable of simulating the actual compressional fatigue of nonwovens in a daily use. The fatigue test was performed at nine different cycles. The compression properties including compression energy, compression linearity and thickness at given pressures with different compressional fatigue cycles have been evaluated with KES-FB3 after fatiguing the samples upto the given cycles. We examined the several formulas for the compression and recovery curves. We found the best equations describing the compression and recovery behaviors. Compression and recovery parameters, $\alpha$ and $\beta$, have been evaluated. The result of compression test for 3D(perpendicular laid) and 2D(spunlace) nonwovens shows different compressional behavior due to the different geometrical properties.

In this study, the objective is the evaluation of the mechanical properties of industrial fabrics. There are several methods currently used ranging from the KES-FB System to the Fast System with the former used most widely. There are limitations, however, in employing the KES-FB system for evaluating thick fabrics used for industrial applications, such as shoes or seat covers. In this preliminary study, the fundamentals for a new system for objective estimation of industrial fabrics are established. The basic limitations of both the new system and the KES-FB system in the evaluation of very thick and strong fabrics are then compared and contrasted. Tensile, shear, and bending were the properties of focus, with the feasibility of development of the new system discussed.
