Phase change compositions, are materials having thermal storage capacity applied for controlling temperature and they are used as thermal insulator for heat storage and releases. For this purpose in textile industries paraffin waxes are used. In this study, the paraffin and N-nonadecane serve as phase change material for thermal energy storage, nano-micro expanded dolomite and expanded perlite was used as supporting agent. This method was applied expressed for textile thermal protection for the irst time. It should be noted that, the inherent structure of the expanded absorbers did not change in the composite material. Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM) were used to determine the chemical structure and microstructure of the composite phase-change materials, respectively. FT-IR analysis indicated that there was no chemical interaction between materials in composite. The SEM results showed that the phase change materials was well absorbed in the porous network of the expanded materials, and there was no leakage of the phase change materials from the fabrics even when it was in the molten state. The heat transfer measurement and DSC test were used to determine the thermal properties of composite fabrics which showed that the thermal properties of the fabric has a significant impact on these operations. The DSC results indicated that latent heat increased with phase change material content in composite of phase change materials. Moisture transfer property has substantial effects on textiles comfortable attributes. The moisture transfer properties were measured and the results showed that by adding composite to textile surface, moisture and temperature transfer will be reduced (due to high thickness and filling fabric pores by composite). By investigation of moisture and temperature properties dynamically, following results were obtained: The presence of composite on fabric surface has increased fabric thickness but moisture transfer was reduced. The temperature in two side (above, underneath) of the was different. This difference demonstrate that it may be because of presence the phase change materials which have low thermal conductivity and on the other hand, dolomite and perlite have thermal insulation properties. As a result, prepared samples can be applied in textiles thermal protection which can be served as an appropriate and suitable insulator. This method can be introduced as an easy and cheap way of insulating textile fabrics.
