With polyester fabric through microwave irradiated to raise the combination absorbed ability and strength between fabric and rubber of conveyer belt in this research. The results shows that fabric after microwave irradiation in energy power 630W、time 90 sec can get the maximum value of adhesion strength between fabric to fabric and fabric to rubber. Compared the fabric after microwave irradiation with the fabric without Resorcinol Formaldehyde Latex agent, which the fabric to fabric and fabric to rubber of adhesion can raise 30.2% and 40.9%.
