涤纶织物结构与其血液相容性及生物力学性能

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。

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

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,blood-coagulation 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 blood-compatibility and biological mechanics performance was discussed preliminarily.
