Composite fabric waterproof and moisture-permeable principle
Waterproof and moisture-permeable means that outside water cannot pass through the film, but the sweat emitted by the human body can diffuse to the outside world through the film in the form of water vapor.
The principle of realizing this function:
1) The surface of the fabric needs to be water-repellent, and the nano-coating material is used, so that even if it rains, there will be no rainwater to wet the fabric surface;
2) Micropores are formed on the fabric by interlacing polyester fiber materials to ensure that water vapor molecules can pass through, while water molecules are blocked, and the organization of the multi-layer labyrinth structure enhances the windproof effect of the fabric;
