Directional water transport is a predominant part of functional textiles used for continuous sweat release in daily life. However, it has remained a great challenge to design such textiles which ensure continuous directional water transport and superior prevention of water penetration in the reverse direction. Here, a scalable strategy is reported to create trilayered fibrous membranes with progressive wettability by introducing a transfer layer, which can guide the directional water transport continuously and spontaneously, thus preventing the skin from being rewetted. The resulting trilayered fibrous membranes exhibit a high one‐way transport index R (1021%) and a desired breakthrough pressure (16.1 cm H₂O) in the reverse direction, indicating an ultrahigh directional water transport capacity. Moreover, on the basis of water transport behavior, a plausible mechanism is proposed to provide insight into the integrative and cooperative driving forces at the interfaces of trilayered hydrophobic/transfer/superhydrophilic fibrous membranes. The successful synthesis of such fascinating materials would be valuable for the design of functional textiles with directional water transport properties for personal drying applications.

功能性吸湿纺织品的三层纤维膜中的连续，自发和定向水传输

定向水传输是功能性纺织品的主要组成部分，这些纺织品在日常生活中用于持续释放汗水。然而，设计这样的纺织品仍然是一个巨大的挑战，这些纺织品要确保连续的定向水传输并能很好地防止反方向的水渗透。在这里，据报道，一种可扩展的策略通过引入转移层来创建具有渐进性可润湿性的三层纤维膜，该转移层可以连续，自发地引导定向水的运输，从而防止皮肤重新湿润。所得的三层纤维膜表现出较高的单向传输指数R（1021％）和所需的突破压力（16.1 cm H ₂O）相反，表示超高的定向水传输能力。此外，基于水的输送行为，提出了一种合理的机制，以提供对三层疏水/转移/超亲水性纤维膜界面的整合和协同驱动力的见解。这种引人入胜的材料的成功合成对于具有定向水传输特性的功能性纺织品的设计对于个人干燥应用而言将是有价值的。
