Personal moisture management fabrics that facilitate sweat transport away from the skin are highly desirable for wearer’s comfort and performance. Here, we demonstrate a “skin-like” directional liquid transport fabric, which enables continuous one-way liquid flow through spatially distributed channels acting like “sweating glands” yet repels external liquid contaminants. The water transmission rate can be 15 times greater than that of best commercial breathable fabrics. This exceptional property is achieved by creating gradient wettability channels across a predominantly superhydrophobic substrate. The flow directionality is explained by the Gibbs pinning criterion. The permeability, mechanical property, and abrasion resistance (up to 10,000 cycles) of the fabric were not affected by the treatment. In addition to functional clothing, this concept can be extended for developing materials for oil-water separation, wound dressing, geotechnical engineering, flexible microfluidics, and fuel cell membranes.

对于穿戴者的舒适性和性能而言，非常需要有助于水分从皮肤上转移出汗的个人水分管理织物。在这里，我们演示了一种“皮肤样”的定向液体传输织物，该织物能够使连续的单向液体流经空间分布的通道，像“汗腺”一样起作用，同时还能排斥外部液体污染物。透水率可以是最好的商用透气性织物的透水率的15倍。通过在主要是超疏水性基材上形成梯度润湿通道，可以实现这种非凡的性能。流动方向性由Gibbs钉扎标准解释。织物的渗透性，机械性能和耐磨性（最多10,000个循环）不受处理的影响。除了功能性服装，
