Study on Heat Dissipation of Thermal Fabrics under Different Warm-Keeping Covers
Precise temperature control is important in thermal textiles. As the cover on the thermal textiles can greatly affect
the heat dissipation and further change the temperature control. However, the traditional thermal theory about mere heat
dissipation cannot be applied directly to the latest active thermal and wearable textiles and there is no relevant reference as well.
Therefore, the effect of covers on temperature control of the thermal fabric is explored when different numbers of covers are
applied in this study. Thus changing the material or the number of the covers on the thermal fabric becomes a new and effective
way to adjust temperature for thermal textiles. This research work shows promising application in some extreme environment
where increasing electrical power input to achieve expected temperature is not a perfect solution. Moreover, it is found that the
thermal resistance of a fabric cover measured by the thermal conductivity tester machine can directly be applied to predict the
actual situation during heating process when thermal resistance of the fabric cover is not too big, which can makes the fabric
selecting process more efficient and help the factories save much time.
