We used the PET/Nylon conveyer belt fabric through microwave irradiated to raise the absorbed ability and strength the combination with fabric and rubber in this research. The results shows that fabric after microwave irradiation in microwave power 490W、time 60 (sec) can get the maximum value between fabric to fabric and fabric to rubber. We compare the fabric after microwave irradiation with the fabric without agent. that the fabric to fabric and fabric to rubber of adhesion can raise 42.2% and 38.5%.
