摘　　要：利用改造过的两梭箱剑杆织机,选择已经广泛用于人造血管制备的真丝和涤纶为材料,制备了经纬纱为2.4 tex/12 f生丝×2.4 tex/12 f熟丝、2.4 tex/12 f生丝×2.4 tex/12 f涤纶,经纬密为1 100根/(10 cm)×800根/(10 cm)、1 100根/(10 cm)×1 400根/(10 cm)、1 100根/(10 cm)×2 000根/(10 cm),基础组织为平纹的6种腔内隔绝分叉机织人造血管。试样经后处理后进行表面微观形貌、管壁厚度、渗透性、力学性能等测试,并分析其影响因素。试验结果表明,真丝制成的BWEPs的性能相对优越,更适用于人体的移植。By using a modified double-box rapier loom,6 kinds of bifurcated woven endovascular prostheses were made from silk and polyester yarns, which have been wildly adopted in manufacturing of endovascular prostheses. For the 6 kinds of bifurcated woven endovascular prostheses,the warp and weft yarns were 2. 4 tex/12 f raw silk × 2. 4 tex/12 f degummed silk,and2. 4 tex/12 f raw silk × 2. 4 tex/12 f PET; the warp and weft densities were 1 100/（ 10 cm） ×800/（ 10 cm）,1 100/（ 10 cm） × 1 400/（ 10 cm） and 1 100/（ 10 cm） × 2 000/（ 10 cm）. The surface morphology,wall thickness,permeability and mechanical properties of the bifurcated woven endovascular prostheses after post-treatment were examined and the impacting factors were analyzed.The experimental results showed that the bifurcated woven endovascular prostheses made from pure silk possessed better performance and were more suitable to be used in transplanting of human body.
