In this paper, the thermal insulation of coated fabric by nanocomposites has been studied. In fact, a resin/clay mixture was deposited on a 100 % cotton fabric and tested using a PASOD device for measuring the adiathermic power. The enhancement of fabric thermal insulation was noticed by calculating the difference in temperature between the inside and the outside of fabric. The innovation of this work is that the used clay is a Tunisian natural one which is simply a mixture of several sorts of clays (kaolinite, dolomite, calcite, illite, and quartz) and which has the advantage to be so cheap. Moreover, high clay percentages of 4,17 % to 37,8 % were applied to perform nanocomposites with, which never have been tried before. This clay has been cleaned, purified, dried, and steered with different resins which are actually used in the textile field for several applications such as comfort, elasticity or impermeability. It has been concluded that the increasing quantity of clay enhance significantly the thermal insulation of a 400 g/m2 sergey fabric 100% cotton. The mathematical equation has proved to be effective in predicting the fabric thermal resistance, simply by knowing the adiathermic power value. In fact, the measure of the thermal resistance demands a long time to be evaluated, but the adiathermic power can be evaluated by a concise operation which lasts only 15 min. This good agreement between these values has been demonstrated by mathematical formulas linking the clay percentage, coating, nanocomposite deposited quantities, and the used resin. The result of theses computations indicates that clay application in nanocomposites proved its importance because the thermal insulation properties of the fabric are really enhanced according to the clay percentage in the coating. The average of this enhancement is about 20 to 30 % and this is upon the used resin, the deposited quantity, and the clay percentage present in the nanocomposite.
