Cooling methods in buildings often use more energy than needed because they cool the entire space instead of focusing on individual comfort. Textiles with personal thermal management with the aim of maintaining the thermal comfort of humans and saving energy consumption have been considered in recent researches. This project presents a new cooling textile that has a cooling function through the reflection of the sun's radiation and the transmittance of the body's radiation to the environment. This textile was prepared by covering woven ring fabrics with the dola ring technique, which is on the fabric with cotton thread and under it with polyester multifilament. Coating with nanoparticles of zinc oxide (ZnO) and calcium carbonate (CaCO3) (with dimensions of about 100-200 nm) along with nylon 6 polymer was done using the electrospray method. To eva‎luate the performance of coated fabric in cooling applications; Various tests were performed, including measuring the reflectivity of sunlight, transmittance in the spectrum of body radiation, measuring skin temperature, measuring thickness and air permeability. The results show that the manufactured textile achieved 84% reflectivity in the visible part of the sun's radiation and prevents the increase in skin temperature so that the skin temperature was shown to be 2 degrees lower when the textile was on it. This research will help develop advanced textile materials suitable for use in sportswear, outdoor clothing and other areas where temperature regulation is essential, paving the way for innovative solutions in the textile industry.
