Dual‐Cooling Textile Enables Vertical Heat Dissipation and Sweat Evaporation For Thermal and Moisture Regulation.

Personal thermal management textiles have garnered a lot of attention because they can efficiently preserve the body's thermal and moisture comfort while saving energy consumption. Nonetheless, conduction cooling‐based textile research is scarce and frequently encounters obstacles like overlooking through‐plane heat conduction, moisture management, and durability assurance. Here, a dual‐cooling textile (DCT) that combines high‐efficiency heat dissipation and sweat evaporation with a 3D thermal conductive network and Janus wetting structure is demonstrated. The DCT achieves notable in‐plane and through‐plane thermal conductivity (8.57 and 0.70 W m−1 K−1), along with practical mechanical qualities (tensile fracture strength of 65 MPa), under the influence of the 3D multistage thermal conduction network. Additionally, the DCT benefits from its Janus wetting structure, exhibiting unidirectional moisture‐wicking capability (transport index of 1081%) and fast water evaporation performance (0.34 g h−1). Rapid heat dissipation and sweat evaporation are advantageous features for the cooling of the human body in both static and dynamic situations. Compared to cotton fabric, DCT can lower the temperature by up to 3.7 °C. This strategy provides a fresh perspective on the development of advanced functional textiles for personalized cooling and energy savings in buildings. [ABSTRACT FROM AUTHOR]
