Moisture Vapor Resistance - Thermal Comfort Properties of

The water vapor resistance of the N100 fabric was superior to 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 for allowing moisture to pass

Thermal Fabric Resistance & Water Vapor Resistance and

“Heat and humidity comfort” is measured by thermal resistance and water vapor resistance. Thermal resistance is simply the ability to block heat transfer. Clothing is born to insulate and keep warm, to prevent excess heat from escaping and to ensure that the body is in a comfortable temperature environment.

thermal comfort: temperature and humidity control in buildings

Relative humidity is the ratio of the maximum amount of water vapor that the air can contain at current temperatures and the actual amount of water in the air. If the relative humidity is between 40 and 70%, the thermal comfort is not significantly affected. However, when the HVAC units failoperating optimally, humidity levels may drop to an unacceptable level and rise to a higher level.

Homme comfort is the most important performance and should be tested by a professional anti-sweat heating panel.
