According to the Commodity Market Analysis System of Shengyi Society, the price of domestic polyester filament has declined this week. Currently, the mainstream polyester filament factories in Jiangsu and Zhejiang, POY (150D/48F), offer prices of 7600-7800 yuan/ton, polyester DTY (150D/48F low elasticity), offer prices of 9100-9400 yuan/ton, and polyester FDY (150D/96F), offer prices of 8100-8300 yuan/ton.

In early August, the polyester factory began a new round of promotions, with prices for polyester filament reduced compared to before, offering discounts ranging from 100-200 yuan/ton. The increase in inventory pressure in polyester factories is the most important reason for promotions, as the overall inventory in the polyester market is concentrated between 11-24 days. Secondly, in terms of raw materials, the PTA internal price has dropped from the highest point of 6110 yuan/ton to the current 5600 yuan/ton, a decrease of 510 yuan/ton; The internal price of ethylene glycol has dropped from the highest of 4820 yuan/ton to the current 4596 yuan/ton, a decrease of 224 yuan/ton. The decline in raw material prices has provided polyester factories with greater profit margins, which has also prompted them to lower prices and offer discounts.

Overall, the recent market trend of polyester filament has shown a downward adjustment in prices, and the future development of the market will be influenced by various factors, including raw material prices, market supply and demand, export situation, and policy environment.
