| 中文摘要: |
| 研究1100dtex/2-25EPI聚酯浸胶帘线在半钢子午线轮胎冠带层中的应用。结果表明：与930dtex/2-28EPI锦纶66帘线相比，1100dtex/2-25EPI聚酯浸胶帘线的断裂强力增大，H抽出力相当，尺寸稳定性较好；以1100dtex/2-25EPI聚酯浸胶帘线替代930dtex/2-28EPI锦纶66帘线用于205/55R16 91V轮胎和185/65R15 88H轮胎的冠带层中，成品轮胎的高速性能提高，滚动阻力降低，其他室内性能和室外性能均基本相当。 |
| 英文摘要: |
| The application of 1100dtex/2-25EPI polyester dipped cord in the crown layer of steel-belted radial tire was studied.The results showed that compared with 930dtex/2-28EPI nylon 66 cord，the breaking strength of 1100dtex/2-25EPI polyester dipped cord increased，the H pull-out force was comparable and the dimensional stability was better.Using 1100dtex/2-25EPI polyester dipped cord instead of 930dtex/2-28EPI nylon 66 cord in the crown layer of 205/55R16 91V tire and 185/65R15 88H tire，the high-speed performance of the finished tires was improved，the rolling resistance was reduced，the other indoor and outdoor performance were basically equivalent. |
