A non-woven garment for deep vein thrombosis prevention includes a body having a central panel, a left side panel, and a right side panel formed with a number of attachment straps having an integral fastener and a cover. A single air chamber receiving air from a pump through a flexible air supply tube is formed on the central penal when the body and the cover are welded through an RF welding method. The body and the cover are made of the same dielectric material for their inner layers to be welded and another same material for the outer layers which can be placed against a patients skin. The one-step RF welding method eliminates the need for tricot lining and binding and less material is used in manufacturing. Thus, the present invention significantly reduces the manufacturing steps, time, cost, and use of material in manufacturing.
