Polybutester is a unique copolymer that can be extruded as a flexible monofilament nonabsorbable suture. The mechanical performance of this new suture material was compared with that of polypropylene and nylon. The results indicate that polybutester sutures are as strong, have the same degree of total elongation at break and knot as the other monofilament sutures. In contrast with polypropylene and nylon sutures, the polybutester sutures have a perceptible stretch, are more elastic and flexible, and exhibit less creep. Polybutester sutures appear to be an acceptable alternative to polypropylene and nylon sutures and their unique mechanical properties may even prove to be superior in vivo.
聚丁酯是一种独特的共聚物，可被挤压成柔性单丝不可吸收缝线。将这种新型缝线材料的力学性能与聚丙烯和尼龙的力学性能进行了比较。结果表明，聚丁酯缝线与其他单丝缝线一样牢固，在断裂和打结时的总伸长程度相同。与聚丙烯和尼龙缝线相比，聚丁酯缝线有明显的拉伸性，更具弹性和柔韧性，且蠕变较小。聚丁酯缝线似乎是聚丙烯和尼龙缝线的可接受替代品，其独特的力学性能甚至可能在体内表现更优。
