Abstract: A high elastic fiber cup includes an inner layer, an outer layer and a pad. The inner and outer layers include wrapping clothes having high elastic fiber bodies attached on the inner surfaces thereof and cut into combed fiber sheets, respectively, or include a double-side multispandex or a three-layer of elastic fiber knitting cloth. The pad is made of a high elastic fiber body which is cut into a three-dimensional block and is attached to and between the inner and outer layers by using gel. An excellent elasticity and air permeability is obtained for recovering its initial shape quickly after being pressed and achieving a comfortable satisfaction.
