Abstract
Climate Change and Global Warming affect human life in many ways. So, we have to know heat conducting characteristics of fabrics in hot or cold environment and find some measures to spend comfortably in hot and cold seasons. We studied thermal conductivities of various fabrics (Yamada 1997) and obtained knowledge on why silk is cool(Yamada and Naruse 2002).
In the present study, thermal conductivities are measured in the atmosphere of several temperatures and humidities. And it was found thermal conductivity of fabrics is determined by the volume fractions and the thermal conductivities of air, water and fibers.
Main part of heat is transfered through fibers and for this part of the thermal conductivity the result showed that the effect of the volume fraction of fibers was grater than the effect of temperature.
