Effective moisture management within the microenvironment of protective clothing is crucial for maintaining garment performance and wearer comfort. The inherent properties of fabrics and the structural of protective garments often hinder the discharge of sweat to the external environment. Here, we present a novel 3D moisture transport fabric, engineered with gradient wetting properties along both the thickness and length dimensions. This fabric can transport moisture from the inner to the outer surface within approximately 5 s, achieving a maximum accumulative one-way transport capability of 1189.1 in the thickness direction. Additionally, by further directing moisture along the constructed wetting gradient on the fabric's outer surface, the moisture diffusion distance in the gradient direction was up to 2.6 times greater than in other directions. This approach will enhance moisture transport and management within protective clothing and can be further extended to the development of materials for oil-water separation, wound dressings, flexible microfluidics, and fuel cell membranes.
