A Geometric Analysis of the Loop Form of a Tricot Stitch Knitted Fabric

A tricot stitch knitted fabric has been used in medical stents, such as tracheal stents and external stents. Both geometric form and porosity of the stent are key factors in clinical use. One loop of the tricot stitch knitted fabric was divided into seven parts, and the loop form was analyzed. The geometric characteristics under extreme condition for both latitudinal and longitudinal extension were given. The relationships between geometrical parameters of a tricot stitch knitted fabric were obtained.
