| 中文摘要: |
| 研究锦纶66（N66）和聚酯混纺体（EPT66）帘线替代N66帘线在轮胎冠带层中的应用。结果表明：与N66帘线相比，EPT66帘线具有更低的定负荷伸长率和干热收缩率、更高的模量以及更优异的低温蠕变性能；与冠带层使用N66帘线的成品轮胎相比，冠带层使用EPT66帘线的成品轮胎的充气外缘尺寸、高速性能、耐久性能和强度均相当，使用EPT66帘线的成品轮胎安全性能可靠，为混纺新材料在轮胎中的应用提供了参考依据。 |
| 英文摘要: |
| The application of nylon66（N66） and polyester blend（EPT66） cord instead of N66 cord in tire cap ply was studied.The results showed that，compared with N66 cord，EPT66 cord had lower constant load elongation，dry heat shrinkage，higher modulus and better low temperature creep properties.Compared with the finished tire using N66 cord in cap ply，the inflation peripheral dimension，high-speed performance，durability and strength of the finished tire using EPT66 cord in cap ply were equivalent，and the safety performance of the finished tire using EPT66 cord was reliable，which provided a reference basis for the application of blended new materials in tires. |
