thirdly, after water vapor is introduced for 8 hours, stopping introducing the water vapor, taking down the shoe to be measured and immediately measuring to obtain the mass m2 of the shoe to be measured, and calculating to obtain the moisture absorption W of the shoe to be measured which is m2-m 1;
fourthly, the vapor-permeable shoe mold is arranged in the regulated shoe to be measured, the vapor inlet pipe, the vapor return pipe and the differential pressure sensor are connected with the vapor-permeable shoe mold, the vapor is continuously introduced, the timing is restarted, and the pressure difference between the vapor in the vapor-permeable shoe mold and the ambient atmosphere is stabilized at 0.12 +/-0.02 kPa;
and fifthly, after introducing water vapor for 8 hours, stopping introducing the water vapor, placing 160-200g of dried silica gel particles on a placing tray of the measuring scale, turning over a rotating frame to transfer the measuring scale from the outside of the test box to the inside of the test box, sealing the test box, reading the mass of the silica gel as m3 when the humidity in the test box is reduced to a relatively stable value, stopping introducing the water vapor into the vapor-permeable shoe mold for 4 hours, reading the mass of the silica gel as m4 when the humidity in the test box is relatively stable again, and calculating to obtain the moisture permeability P of the shoe to be measured as (m4-m 3)/4.
