摘要
Occurrence of vascular diseases is increasing and leads to rising demand for the STENT-GRAFT( SG). To ensure the SG function properly,the materials should have low blood permeability and good mechanical properties. So far, there have been few systematic studies on the relationship between textile structures and mechanical properties of the bio-textiles used in the SG. In this study, six types of biomedical PET fabrics with different yarn structures and fabric structures were designed and fabricated. All the SG materials could meet the requirement of thickness,except the sample of 30 d × 20 d with 2 /2 twill construction,which was thicker than 0. 12 mm. Bursting strength and water permeability( WP) of the six samples were also tested. Through the comparison of comprehensive performance,the PET fabric 30 d × 20 d /12 f with2 /2 twill construction with both good resistances to permeability and bursting strength, might have good prospect in applications of vascular engineering.
