The use of vascular grafts to replace damaged native vessels plays a significant role in clinical cardiovascular disease treatment. Comparable mechanical properties of small-diameter vascular grafts to that of native vessels are crucial and challenging. This study examines how different fabrics and yarns influence the mechanical properties of vascular grafts and evaluate the effectiveness of vascular grafts being used as native vessels. Five wrapped yarns are made into braids, warp knits, and weft knits. These knits are incorporated with PVA via freeze-thawing in order to form vascular grafts that are evaluated with circular properties and bursting strength tests. The test results indicate that the number of freeze-thawing cycles is related to the compliance and bursting strength of vascular grafts. In addition, the combination of spandex fibers improves the compliance of both the fabrics and vascular grafts.
