摘　　要：研究平衡条件对生物基聚酰胺56(PA56)浸胶帘线性能的影响,并与锦纶66(N66)浸胶帘线进行对比。结果表明:平衡条件对生物基PA56浸胶帘线和N66浸胶帘线的强力、断裂伸长率、定负荷伸长率等性能的影响略有差异;预干燥条件对生物基PA56浸胶帘线的物理性能有一定影响,生物基PA56吸潮帘线(回潮率2.55%)与干燥帘线(回潮率0.90%)的性能差异明显;相对湿度从55%增大到98%,生物基PA56浸胶帘线的回潮率变化较N66浸胶帘线大;生物基PA56浸胶帘布具有良好的耐屈挠疲劳性能和动态力学性能。The effect of equilibrium conditions on properties of bio-based polyamide 56(PA56)dipped cord was studied,and compared with nylon 66(N66)dipped cord.The results showed that the effects of equilibrium conditions on the strength,elongation at break and elongation at constant load of the bio-based PA56 dipped cord and N66 dipped cord were slightly different.Pre-drying conditions had a certain influence on the physical properties of the bio-based PA56 dipped cord,and the performance difference between the properties of bio-based PA56 moisture absorbing cord(moisture regain was 2.55%)and dry cord(moisture regain was 0.90%)was obvious.When the relative humidity increased from 55%to 98%,the moisture regain of bio-based PA56 dipped cord changed more than that of N66 dipped cord.Bio-based PA56 dipped cord had good flexural fatigue resistance and dynamic mechanical properties.
