Healthcare medical textiles require local microclimate control over sweat transmission and evaporation. However, existing strategies mainly focus on complicating the preparation process or sacrificing breathability and comfort. Herein, we design a lightweight and scalable knitted fabric featuring a double-layer structure consisting of hydrophilic ultrafine polyester and hydrophobic conventional yarns to achieve high moisture transport. These fabrics displayed an ideal directional water transport ability (one-way moisture transport capacity 718%) and anti-regurgitation compared with common cotton fabric. By distributing pores within the textile structure, these fabrics additionally exhibited beneficial water evaporation and heat dissipation. Simultaneously, the theoretical calculation verified that while the bottom layer has increased fiber density and looping area, fabrics are conductive to unidirectional moisture transport. These findings highlight the potential of variable pore knitted textile for personal sweat management, healthcare comfort regulation, and the relief of global energy issues.
