Abstract: An electrothermal article with a foldable structure includes an upper sheet and a lower sheet both made from a hot-melt gum, a bundle of fibers made from a carbon fiber or a stainless steel. The fibers are received between the up and lower sheets and arranged as a sinusoid. After a thermal pressing step, the shape and the location of the fibers are fixed with the two sheets. In this arrangement, the heating wire is difficult to break when bent inappropriately or during a washing operation. In addition, the fibers are never exposed into the air along the seaming line for a long period using.
