涤纶织物结构与其血液相容性及生物力学性能

Influence of polyester fabric structure on its blood-compatibility and biological mechanics performance

对涤纶机织物三原组织平纹、斜纹、缎纹及针织物基本组织纬平针、双罗纹进行了动态凝血实验、凝血因子检验实验和血小板黏附实验,并对血液相容性进行模糊综合评判。结果表明,机织缎纹织物不易引起血液凝固,血液相容性较好。同时表征了不同织物的渗透性、孔隙率,拉伸强度、顶破强度等相关的生物力学性能;初步探讨了织物结构对其血液相容性和生物力学性能的影响。

The effect of different polyester fabric structures （plain, twill and satin of the woven, jersey and interlock of the knitted） on the blood-compatibility of the fabric was studied by kinetic clotting, bloodcoagulation factor and platelet adhesion experiments. The mathematical model of fuzzy comprehensive evaluation was used to characterize the total blood-compatibility. The experimental results indicated that the satin woven is not easy to cause the blood-coagulation and has better blood-compatibility. Meanwhile, the biological mechanics performance of different polyester fabric structures was characterized by permeability, void content, tensile strength, and bursting strength and so forth. The influence of fabric structure on its bloodcompatibility and biological mechanics performance was discussed preliminarily.
