Whether it is tear resistance, flexibility, abrasion or impact resistance tests, our various techniques and physical situations will reveal what the strengths and weaknesses of clothing, footwear or leather goods accessories that you made.
Among the many tests that CTC laboratories can offer you, here are three examples of physico-mechanical strength analysis to characterize your products.
This test is used to reproduce heel impacts associated with walking. In this way we can anticipate the impact resistance of the heel and / or its attachment.
The test consists of subjecting the heel to impacts on a pendulum impact tester in order to check that the heel or heel attachment resistance is satirfactory.
The result corresponds to the number of impacts taken to break or detach the heel.
This test reproduces the stresses to which the materials are subjected during flexing movements, and is used to check the behaviour of the materials, their coating finishes, etc.
The test consists of repeating a swinging flex motion after mounting a specimen on a special machine commonly known as the Bally flexometer. The test can be performed dry and/or wet. The results correspond to the number of flexes taken to obtain deterioration of the material (crack, detachment, split, etc.) in dry or wet conditions.
This test is used to evaluate the resistance of glued joints between various parts. This test can be performed as-is or after ageing.
The test consists of taking a sample representative of the joint to be tested, and subjecting it to a constant tensile force in order to measure the separation forces.
The result corresponds to the adhesion strength expressed in daN/cm*.
