International crude oil prices plummeted, and cost support collapsed. Today, the domestic PTA spot market fell sharply. The average market price was 4,619 yuan/ton, down 3.31% from the previous day and up 38.14% year-on-year. The main futures 2201 closed 4632 4650, down 238, or 4.89%. The Honggang Petrochemical and Yadong Petrochemical plants are about to be overhauled, and the domestic PTA plant start-up will decline, but the overall level remains at a high level of 81.71%, and the supply is showing a slight accumulation.The downstream end-customers have low intent to acquire goods and purchase on-demand. The overall market trading atmosphere is light. The end textile enterprises mainly consume inventory, and the wait-and-see atmosphere increases. The start-up load and order situation of warp knitting factories have not improved. At the end of November, some warp knitting factories plan to continue to shut down and reduce the load. Like most warp knitting factories in Haining, the load will reach 50%, some are less than 40%, and the higher is about 80%. It is expected that the start-up load will continue to decline in December.

　　Many mainstream polyester factories are expected to reduce production, PTA supply and demand pressure will increase, and crude oil prices will be superimposed, which will increase the pressure on the cost side. In addition, orders in the domestic market for terminal textiles continued to decline, new orders for foreign trade were not issued smoothly, and factory shipments were slow. As raw materials fell, weaving factories became more cautious.

　　Therefore, judging from the current fundamentals of polyester filament, the upstream and downstream are negative, and it is expected that the price of polyester filament will remain weak in the short term.
