高模量低收缩聚酯帘线在轻载子午线轮胎中的应用

Application of HMLS polyester cord in radial LT tire

高模量低收缩聚酯帘布具有较好的尺寸稳定性 ,可以提高轮胎的安全性能 ,并实现轮胎轻量化。通过对轮胎结构和生产工艺的调整以及合理搭配材料 ,采用高模量低收缩聚酯帘布骨架材料作胎体生产轻载子午线轮胎。该轮胎的外缘尺寸符合国家标准要求 ,轮胎的高速性能和耐久性明显改善。

The HMLS polyester cord could be used to improve the tire safety and reduce the tire weight because its better dimensional stability.The radial LT tires were produced using HMLS polyester cord in carcass ply by modifying the structure design and processing technology of tire.The overall diameter of produced tire was in accordance with the relevant national standard,and the speed performance and endurance of tire were improved significantly.
