| 中文摘要: |
| 研究捻度对超高强度锦纶66帘线性能的影响。结果表明，随着捻度的提高，浸胶帘线的直径、蠕变率、干热收缩率、断裂伸长率、定负荷伸长率、粘合性能和耐疲劳性能提高，断裂强力和初始模量降低，可根据需求选择合适的捻度。 |
| 英文摘要: |
| The effect of twist on the performance of ultra-high strength nylon 66 cord was studied.The results showed that with the increase of twist，the diameter，creep rate，dry heat shrinkage rate，elongation at break，elongation at constant load，adhesion，and fatigue resistance of the dipped cord increased，while the breaking strength and initial modulus decreased.The appropriate twist could be selected according to the needs. |
