| 中文摘要: |
| 对比研究聚酯线绳与聚酯钢化棕丝的性能及其在V带中的应用。结果表明：与聚酯线绳相比，聚酯钢化棕丝的直径、断裂强力、断裂伸长率和定负荷伸长率均较小，与天然橡胶间的粘合强度较大，高温下的干热收缩率较大；与成品聚酯线绳V带相比，聚酯钢化棕丝V带的整根拉伸强度和参考力伸长率较小，线绳拔脱强度较大，疲劳寿命延长，经济效益提高。 |
| 英文摘要: |
| The properties of polyester cord and pre-stretched polyester monofilament， and their application in V-belt were investigated.The results showed that，compared with polyester cord， the diameter，breaking strength， elongation at break and elongation at specified load of pre-stretched polyester monofilament were lower，the dry heat shrinkage at high temperature was higher，and the adhesion strength between pre-stretched polyester monofilament and NR was higher.Compared with the finished polyester cord V-belt，the tensile strength and elongation at reference load of the finished V-belt by using pre-stretched polyester monofilament were lower，the pull out strength of cord was higher，the fatigue lifetime of V-belt was longer，and the economic benefit was improved. |
