This study aimed to determine the effects of relative humidity and fiber properties on the moisture per-meability of multilayer systems by measuring water vapor transmission in the overlapping condition of various fabrics. The results confirmed that the property of the fabric in contact with the humid environment affects the moisture per-meability. If the layer facing the humid environment is hydrophobic and the layer facing the dry environment is supe-rhydrophobic, water vapor transmission increases by up to 17.8% compared to the opposite conditions. Comparing thecorrection values of the water vapor transmission reflecting the thickness of the specimen under the multilayer con-dition showed that permeability was higher when the hydrophilic or hydrophobic layer was facing the humid envi-ronment. The opposite was true from the “push-pull” effect of absorption mechanism. In the case of moisturepermeability, the more hydrophilic the surface facing the humid environment, the more permeable that water vapor dif-fuses and passes through. It was concluded that the “pull-push” effect, in which water vapor diffuses widely through thehydrophilic facing a humid environment and then passes through the hydrophobic layer, contributes to the improvementof permeability. Permeability differed according to the multilayer overlapping condition. When the relative humidity washigh, the “pull-push” effect was insignificant. This is caused by water droplets absorption after the partial migration ofwater due to condensation. These results suggest that the overlapping conditions and properties of fabrics should varydepending on heavy sweating or not.
