The effect of microwave irradiation way on hydrolytic depolymerization of poly (ethylene terephthalate) (PET) was studied at 175°C, 180°C and 185°C. Based on this study, an additional experiment that the intermittent radiation time was one tenth of total reaction time (intermittent radiation (1/10)) was conducted to research the microwave energy utilization. The results showed that the energy efficiency increased as the temperature rose. And the energy utilization of intermittent radiation (1/10) was 16.7% higher than that of the continuous radiation at 175°C.

Hydrophilicity Modification

The hydrophilic modification of poly (ethylene terephthalate)(PET) fabric is significant for industrial production. Its studied by ultraviolet radiation, nanoTiO2, H2O2 and NaOH. The results show the best condition is 3%nanoTiO2, 5%H2O2 and 3%NaOH, under 1000W UV radiation. With only about 30~35 minutes irradiation the PET fabric is nearly to wettable. For 40 minutes irradiation is super hydrophilic, the water contact angle of modified PET fabric can decrease to zero in 3 seconds. The wettability of modified PET fabric was examined. It shows the water absorption of modified PET fabric increase from 85% to 104%, and the capillary rise height can reach from 0.2 to 6.2 cm. Meanwhile the broken strength and elongation change of modified PET fabric tests show its mechanical and physical properties keep good.
