The main components of the polyester ammonia sweat cloth are polyester and spandex. The polyester fiber makes the fabric stiff, wrinkle-resistant, easy to wash and quick-drying, with high strength and no deformation. The spandex fiber has high elasticity, which allows the fabric to stretch freely, providing comfortable and easy movement. This fabric is commonly used in sportswear, such as sports vests, fitness pants, and also in some tight fashionable clothing.
