| 摘 要： | 研究在不同的夹持距离、不同拉伸速率条件下涤纶低弹网络丝机械性能 ,从实验结果得知 ,在相同拉伸速率下 ,断裂强力随夹持距离的增加呈对数关系减少。在相同夹持距离下 ,随着拉伸速率的提高 ,平均断裂强力提高 ,断裂伸长增大 ,断裂比功也增大。

| Abstract: | The mechanical properties of PET low\|elastic interlaced yarn were studied at different clamp distance and drawing rates. The experimental results showed that the breaking strength decreased logarithmically with the increase of clamp distance at constant drawing rate; and the average breaking strength, elongation at break and breaking work all increased with the increase of drawing rate at the same clamp distance. |

| Keywords: | low\|elastic interlaced yarn breaking strength elongation at break breaking work poly(ethylene terephthalate) fiber |
