| Abstract: |
| The new dipped aramid stiff cord for cutting V-belt was studied. The results showed that compared with the conventional dipped aramid stiff cord activated with polymethylene polyphenyl polyisocyanate toluene solution，the new dipped aramid stiff cord activated with activation treatment solution TCHY-11 solved the fluffing problem of the trimming surface and grinding surface of cutting V-belt. The solidify degree of the new dipped aramid stiff cord met the requirements of the production process of cutting V-belt，the breaking strength retention rate was high，and the produced cutting V-belt met the product requirements. |
