In order to establish the testing method for predicting the fabric fatigue phenomena in mechanical properties during the wear, three kinds of woven fabrics, previously used for the wearing test, were subjected to repeated shearing deformation using the KES-F 5 fabric fatigue testing machine which simulates deformation in wear.
The mechanical properties of specimens in each stage of repeated deformation were measured by the KES-FB system, and compared with those caused by the wearing test. Then, the difference of changing process of the mechanical properties between the simulation and the wearing test were discussed. In addition, the changing processes of the morphologies of fibers and yarns were observed by the scanning electron microscopy.
The increasing of hysteresis in the repeated cycle of deformation such as tensile, bending, shearing and compression are more accelerated under the wet condition method, putting a little amount of carborundum on the surface of the specimen than the standard condition method.
The changing process of mechanical properties in the simulation testing by the fatigue testing machine has similar tendency to that of the wearing test.
It is concluded that this testing method is useful to predict the fatigue phenomena of woven fabrics caused by wearing.
