The outer wall of the elastic filaments 211 is provided with seepage-proof grooves 212, and reinforcing ribs 213 are provided inside the seepage-proof grooves 212.

[0027] Among them, the elastic filament 211 is composed of core-spun yarn through the seepage-proof groove 212 and the reinforcing rib 213.

The biodegradable layer 3 is made of recycled polyester fiber.

[0029] When in use, external moisture enters through the breathable surface layer 1, and water molecules are blocked by the quick-drying layer 2. As the composite fabric deforms during wear, the seepage-proof unit 21, with the cooperation of its elastic filaments 211, seepage-proof grooves 212, and reinforcing ribs 213, transmits external or internal airflow. The gas passes through the quick-drying layer 2 to quickly evaporate the water molecules.
