Measurement of textile materials thermal properties

The determination of thermal properties of textile materials is difficult and subject to errors. Here we used two experimental methods. A PhotoPyroElectric method (Front PPE configuration with a modulated heat flow imposed on the surface of the sensor) and a commercial device (Alambeta) based the hot plate method. Two theorical approaches for the latter device were used. We tested the two methods on different textile materials (cotton, modal, wool and spacer). We observe good agreement between thermal conductivities measured with the two methods.
