Sweat Gland-Inspired Skin-like Fabric with Directional Water Transport and Durability for Efficient Personal Moisture Management

Directional water transport textiles are an energy-free approach to improving the comfort of the human body. However, existing strategies mainly focus on enhancing the capacity of directional water transport, complicating the preparation process and limiting the long-term durability of textiles. Herein, a skin-like fabric inspired by sweat glands was prepared in one step by patterning printed hydrophobic paste on the fabric. This skin-like fabric has achieved the desired one-way water transport index (R, 721%), air permeability of 104 mm s–1, and water vapor transmission rate (298 g m–2 h–1). More significantly, due to the strong chemical bonds between the fabric and the coating, the skin-like fabric exhibited a high weight retention of 99.4% after 400 abrasion cycles and stable performance (R, 658%) after 25 h of washing. This work proposes a reliable way to prepare high-performance fabrics with durability, which show great potential for applications in functional textiles for personal moisture management.
