Wearable Cooling Textiles of Thermal Conduction and Sweat Transfer for Personal Thermal Management

Given rising global temperatures, advanced protective textiles hold significant potential to enhance productivity, conserve energy, and improve personal thermal comfort. Extensive research has shown that both thermal conduction and moisture management are equally critical in determining the comfort performance of textiles. Here, we propose a wearable cooling textile (WCT) that integrates thermal conduction and unidirectional moisture transfer through a 3D laminating method. Using thermally conductive fibers. By constructing a 3D thermal conductive network and a double-layer Janus wetting structure, boron nitride nanosheet (BNNS) attached to the 3D framework, endowing the textile with omnidirectional heat dissipation (thermal conductivity of 0.315 W·m^-1·K^-1), unidirectional moisture-wicking properties (transport index of 476%), and a high water evaporation rate (WER, 5209.92 g/m²/day). Compared with commercial cotton fabrics, the WCT reduces temperature by up to 4.1°C due to its cooling mechanism. Thus, this work provides a promising strategy for developing textiles that can effectively regulate both heat and moisture under diverse and demanding environmental conditions.
