Anti Wrinkle Hygroscopic Polyester Air Layer Fabric Anti-wrinkle hygroscopic polyester air layer fabric is a type of fabric that is designed to be wrinkle-resistant and able to absorb and release moisture. It is made from polyester fibers that have been treated with special finishes or coatings to enhance these properties. The hygroscopic nature of the fabric means that it has the ability to absorb moisture from the air or the wearer's body and then release it back into the environment. This helps to keep the fabric dry and comfortable, even during physical activity or in humid conditions. The air layer construction of the fabric refers to the presence of air pockets or gaps between the fibers. This creates a layer of insulation and improves breathability, allowing air to circulate and regulate body temperature.
