Space cooling consumes plenty of energy, thus personal cooling technologies (PCTs) becomes abstractive nowadays. However, most PCTs are heavy and still consume energy，which limited their application among human beings. To gain high cooling capability without energy input, a fabric achieved personal thermal comfort through increasing the transmittance of human thermal radiation and reducing solar energy absorption was designed. The fabric consisted of outer and inner layers, a polyethylene film with nanopores (100-1000 nm in pore size) and a nylon 6 membrane made of nanofibrous (ca. 100 nm in diameter) with beads (ca. 230 nm in diameter), which highly reflected the visible light but not affect the transmission of thermal radiation. Thus, the dual-layered fabric showed a high heat dissipation power, 14.1, 18.0, and 18.0 W/m2 higher than those of cotton, linen, and odile, respectively, illustrating the high cooling capability. Meanwhile, the moisture penetrability and hygroscopic property results suggested the eligible wearing comfort of the designed fabric that it was competent to be applied to summer clothes.
