摘　　要：Conical vascular tubes are of strong demand owing to their formed shape and excellent characters to mimic human blood vessels. In this study,the automatic shuttle loom and computer aided design( CAD) system were customized to prepare a conical vascular graft. Meanwhile, the weaving principle of a conical vascular graft was identified in terms of the lift-drop front rest,and the geometrical relations were established among the cloth fell,front rest and back rest. Also,the change of weft density from the liftdrop motion of the front rest was analyzed,and a strategy was established to compensate the offset of weft density by changing the taken-up length. Afterwards,the proposed weaving principles were demonstrated by weaving a conical vascular graft on the customized shuttle loom.Conical vascniar tubes are of strong demand owing to their formed shape and excellent characters to mimic human blood vessels.
