Abstract: Solar interfacial evaporation technology provides an important approach to the global freshwater crisis due to its low-carbon and sustainable advantages. Hydrogels, with their exceptional moisture management capabilities, tunable evaporation enthalpy, and potential for multifunctional integration, have emerged as core materials for high-performance evaporators. However, pure hydrogel interfacial evaporators face challenges, including poor mechanical properties and limited structural stability. Textile structures,leveraging their material characteristics, structural design, and mature industrial production advantages, offer an innovative pathway to overcome these limitations. This paper systematically reviews the progress in research on textile-structure-enhanced, hydrogel-based solar interfacial evaporators. It first outlines the core role of hydrogels in interfacial evaporation and commonly used hydrogel substrates. Subsequently, it analyses the synergistic effects of textile structures, i.e., fiber composite structures and three-dimensional fabric structures, on optimizing water transport, thermal management, salt crystallization resistance, and mechanical durability in hydrogel-based solar interfacial evaporators. Future development challenges are also discussed.
