Fabric Thermal Resistance Formula: Rct = S（T2 – T1）/ Q Unit: square meter Kelvin per watt , m² K/W Similarly, in ISO 11092, the water vapor resistance of the fabric refers to the ratio between the difference in water vapor pressure on both sides of the fabric and the evaporated heat flux vertically per unit area of fabric.
The water vapor resistance of the N100 fabric was greater than that of the other samples. This was due to its increased thickness and the compactness of its locking structure. According to the result in Figure 5.8, the P96E4 fabric may be suitable for abayas because it has a lower water vapor resistance value, which is desirable to allow moisture
3.3. water vapor resistance from fabric samples according to ISO 11092 Metotte. The ISO 11092 method uses a sweat-wicking hot plate device to simulate the wicking of moisture through the textile when worn next to human skin. This model measures the water vapor resistance of the fabric by measuring the steady state evaporative heat loss.
