Natural leather has good moisture permeability, while polyurethane film has good elasticity and water resistance. In order to study the change trend of moisture permeability of natural leather and polyurethane-coated natural leather, this paper tested the moisture permeability of sheepskin and polyurethane-coated sheepskin under different time and temperature conditions. The results showed that the moisture permeability of sheepskin and PU-coated sheepskin increased with the increase of temperature. The moisture permeability of the two leather was: sheepskinPU-coated sheepskin.
