Conventional textiles primarily focus on sweat removal, neglecting the thermoregulatory function of sweat evaporation. This paper introduces an integrated cooling (i-Cool) textile designed to enhance evaporation and cooling efficiency. By integrating heat conductive pathways and water transport channels, i-Cool demonstrates superior evaporation ability and sweat evaporative cooling efficiency compared to cotton, achieving a >100% reduction in water mass gain ratio and a threefold increase in skin power density increment per unit of sweat evaporation. Artificial sweating skin tests show a 3°C cooling effect with significantly reduced sweat consumption. The i-Cool design principles are validated using commercial fabrics, suggesting promising guidelines for next-generation perspiration management textiles.
