<p>The demand for functional textiles with directional water transport capabilities that can enable the quick absorption of sweat from the skin and efficiently release it into the atmosphere has increased. This study proposes the design of a novel trilayered textile system with asymmetric wettability and pore size gradients to achieve directional moisture transport and rapid sweat evaporation. The system comprises a conventional hydrophobic polyester or nylon tricot fabric with a relatively large pore size as the innermost layer, a weakly hydrophobic polyurethane (PU)/poly(ethylene glycol) diacrylate (PEGDA) nanofibrous membrane as the middle layer, and a hydrophilic PEGDA coating as the outermost layer. The fabrication conditions, including the PU-to-PEGDA blend ratio, PU/PEGDA nanofibrous membrane thickness, and UV irradiation duration for PEGDA crosslinking during the coating process, are optimized using response surface methodology to enhance moisture transport. The resulting trilayered structure exhibits excellent one-way moisture transport capability and moisture management properties, which are driven by an enhanced capillary effect. In particular, the polyester tricot-based trilayered textile system demonstrates superior directional water transport and drying performance compared to the nylon tricot-based trilayered textile system, suggesting its potential for advanced moisture management textile applications.</p>
