Business analysts believe that the current overseas PX supply of raw materials has been restored, and the new domestic devices have successfully discharged, and the PX supply tends to be relaxed. The PTA market faces destocking in June, but the domestic PTA device restarts more in the second half of the year, and the current PTA device load is increased to more than 80%, and it is expected to enter the accumulation stage after July, so there is a weakening risk at the cost end of polyester. In addition, although the current inventory of most manufacturers of polyester filament is at a low level in recent years, but the next 7-August high temperature weather, weaving and other downstream areas of the open probability still has a declining trend, polyester industry is expected to heat up. On the whole, the market price of polyester filament in July will fluctuate and run weakly.
