Ethylene gas sterilized polypropylene monofilaments were tested in a straight pull as well as in a conventional knot pull tensile test. In either case an analysis of the results indicates that the occurrence of "surface steps" may explain the relationship between strength and suture diameter. The present investigation not only shows that the polypropylene specification could be established on a more fundamental basis (using 60% of the ultimate tensile strength as the generalized criterion) but also suggests that other sutures should be evaluated similarly.
对经乙烯气体灭菌的聚丙烯单丝进行了直拉以及传统结拉拉伸试验。在这两种情况下，对结果的分析表明，“表面台阶”的出现可能解释了强度与缝合线直径之间的关系。本研究不仅表明聚丙烯规格可以在更基本的基础上建立（使用极限抗拉强度的60%作为通用标准），还表明其他缝合线也应进行类似评估。
