Simultaneous optimization of plain woven vascular prostheses performances

Abstract

Effects of textile manufacturing parameters such as yarns properties and fabric density on the main performances of polyester plain woven vascular prostheses i.e., porosity, permeability and mechanical properties were investigated by adopting a two-level fractional factorial experimental design. Linear models establishing relationships between each performance and its significant textile manufacturing parameters were developed and are useful to predict performances of plain woven vascular prostheses. Performing overlaid contour plots permitted to determine optimal values for significant textile manufacturing parameters in order to manufacture plain woven prosthesis having at the same time high porosity, low permeability to blood, high mechanical durability and low stiffness. © 2009 Asian Network for Scientific Information.
