| Abstract: |
| 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. |
