Detailed ways

As shown in Fig. 1, the utility model is a kind of upper shoe moisture absorption, moisture permeability tester, described full upper shoe moisture absorption, moisture permeability tester comprises the airtight container chamber 1 of constant temperature and humidity and steam generating device, in airtight container The cavity is provided with an absorption device 7, a weighing device 8 and a fixed bracket 6. The fixed bracket 6 is equipped with a full-top shoe top sealing device 2, and the full top shoe top sealing device 2 is provided with an air inlet and a return port. The full top shoe top sealing device 2 is connected to the steam generating device 2 through the intake pipe 3 and the return pipe 4, and the full top shoe top sealing device 2 is also provided with a pressure gas port 5, which is connected to the dry gas generating device. Connect, provide a certain pressure in the shoe to make the water vapor fully circulate in the shoe cavity and finally flow out from the return pipe 4.
