Personal cooling generally controls the temperature of an individual instead of a large space and therefore needs less energy. In this study, a novel design of a personal cooling textile utilizing thermal radiation to dissipate excessive heat on hot days was proposed for the first time, which was a tri-layered structure of nylon (PA), polyvinylidene fluoride (PVDF) and polyethylene (PE). By selectively absorbing/emitting the thermal radiation (η=3.44) and reflecting sunlight (> 90%), the composite textile decreased the temperature of the human body by 4.5-6.5 ^oC under direct sunlight, showing a high cooling capability, ca. 2.5 times that of traditional natural textiles. The composite textile provided cooling powers of 72.78 W/m² indoors and 118.18 W/m² outdoors, much more than traditional natural textiles. This cooling textile has the potential to be widely used among ordinary persons owing to the characteristics of lightweight, high cooling capability, high wearable comfort, no need for energy input and economy.

个人冷却通常控制个人的温度，而不是控制大空间，因此需要较少的能量。在这项研究中，首次提出了一种新颖的个人冷却纺织品设计，该设计利用热辐射在炎热的天气中消散过多的热量，它是尼龙（PA），聚偏二氟乙烯（PVDF）和聚乙烯（ PE）。通过选择性地吸收/发射热辐射（η= 3.44）并反射太阳光（> 90％），该复合纺织品在阳光直射下将人体温度降低了4.5-6.5 ^o C，显示出很高的冷却能力，大约为50℃。是传统天然纺织品的2.5倍。该复合纺织品在室内提供了72.78 W / m ^2的制冷功率，在室内提供了118.18 W / m ^2的制冷功率。在户外，比传统的天然纺织品要多得多。由于具有轻量，高冷却能力，高穿着舒适性，不需要能量输入和经济的特性，该冷却纺织品具有在普通人中广泛使用的潜力。
