This simple method of measuring the thermal diffusivity of nonwovens requires a minimum of specialized equipment and can be easily performed on a personal computer. Thermal conductivity can be obtained from the thermal diffusivity if the heat capacity and bulk density of the sample are known. The technique was used to study the effect of a fiber's structural parameters on the conductivity of nonwovens. The results indicate that conductivity decreases if the nonwoven is compressed, is made with finer fibers, or has a reflective coating. This decrease occurs because of a reduction in the radiation component of heat transfer. 10 refs.
