Permeabilimeter for testing water absorption and desorption of insole and insock
REFERENCE 5067
Determination of water absorption and desorption. Machine for testing the water resistance of heavy leathers. This method allows you to test absorption time, absorption area and water absorption rate. PRINCIPLES OF THIS METHOD: It can be carried out on all kind of heavy leather, insocks and insoles. Test piece keeps continuously wet on one of its surfaces and is submitted to repeated flexing under a given pressure, in the same manner as the insole of a shoe during walking. This method allows to measure several features according to time of heavy leather related to water resistance.
