The main aim of this work is to investigation on the thermal conduction properties of textiles by means of impregnating the fabrics with ceramic powder. The fabric is immersed in a solution consist of ceramic powder, a special wax and its solvent. In this way the ceramic particles are dispersed uniformly in the fabric voids. The aim of the wax is to connect the ceramic particles to the fibers without any change in fabric flexibility. In order to study the thermal conductivity of the produced fabrics a hot plate was designed and manufactured. The hot plate has a uniform temperature is ±1 degree centigrade. In order to measure the temperature of the cool side of the fabric infrared thermometer fluke 62 was used. Three kinds of ceramic powder were used, i.e. silica, kaolin and calcium carbide has more effect on reduction of thermal conductivity of the fabrics in comparison to the other two. The increase of the percentage of ceramic powder leads to reduction of heat conducted through the materials. A thin aluminum sheet was also used to make a multilayer construction consisting of two layers of fabrics and a layer of aluminum sheet in the middle. The multilayer of fabrics and aluminum sheet showed considerable effect on the reduction of thermal conductivity in comparison to the same two layers of fabrics without the aluminum sheet. A method is also presented to calculate the thermal coefficient of the fabrics using the heat transfer equations
