The research using the PET/Nylon conveyer belt fabric through microwave irradiate to process raise the absorbed ability and replace to strength the combination of fabric and rubber. The result shows that fabric at microwave irradiate for 490W、time 60 (sec), between cloth to cloth and cloth to rubber can get the maximum value compare to the fabric without agent, the fabric of adhesion between cloth to cloth and cloth to rubber can raise 42.2% and 38.5%.
