Cardiovascular disease is one of important problems that the world countries face to. Especially for atherosclerosis and its concerned vascular diseases, they needs to be cured via bypass surgery. Consequently, developing small-diameter vascular grafts becomes important. This study aims to fabricate the tubular braid, and then evaluate its manufacturing methods and properties. In this paper, PET/Spandex hybrid yarn was braided into the tubular braid by braider. By repeated braiding, the layers of the tubular braid increases, producing multi-group tubular braids with varying thickness. After by the thickness and tensile strength tests, the physical properties of braids were estimated. The result demonstrates that, as increase of layers, the tensile strength also increases.
