AI Technical Summary
Traditional textiles expand when the body sweats heavily, increasing their weight and creating a stuffy feeling. Furthermore, existing moisture-wicking and quick-drying fabrics lack intelligent adjustment mechanisms after sweating, affecting wearing comfort.
An active layer with good hydrophilicity and large moisture absorption deformation and a passive layer with poor moisture absorption and not easily deformed are used. The active layer is automatically curled to form a cavity when it gets wet, which increases air circulation. The connection durability is ensured by combining hot pressing or dispensing methods.
It automatically adjusts airflow in humid environments, improving wearing comfort, reducing stuffiness, and enhancing breathability and heat dissipation.
