According to the Commodity Market Analysis System of Shengyi Society, the overall price of polyester filament in August showed a trend of recovery. The market is affected by factors such as cost and supply and demand. As of August 29th, the mainstream polyester filament factories in Jiangsu and Zhejiang Province quoted POY (150D/48F) at 6800-6950 yuan/ton, polyester DTY (150D/48F low elasticity) at 8000-8150 yuan/ton, and polyester FDY (150D/96F) at 7000-7200 yuan/ton.

The specific trend is as follows:
Rising in early August: The price of polyester filament increased slightly in early August. On August 12th, some polyester factories raised the price of FDY and other specifications by 50-100 yuan/ton. FDY production and sales significantly rebounded over the weekend, with local POY production and sales rates as high as 700%.
Mid month decline: Prices fell in mid August. As of August 15th, the mainstream polyester filament factories in Jiangsu and Zhejiang, POY (150D/48F), quoted at 6600-6900 yuan/ton, polyester DTY (150D/48F low elasticity) at 7800-8050 yuan/ton, and polyester FDY (150D/96F) at 7000-7200 yuan/ton. As of August 23rd, POY prices range from 7400-7600 yuan/ton, DTY prices range from 9000-9200 yuan/ton, and FDY prices range from 8000-8200 yuan/ton.
In late August, prices rose again. On August 26th, major polyester filament manufacturers raised their prices one after another, with DTY rising by 50 yuan, some specifications rising by 100 yuan, and some factories directly reporting a price increase of 200 yuan/ton.
Cost side: At the beginning of the month, due to lower than expected demand and US economic data, polyester raw materials were weak, PX hit a new low since its listing, PTA fell below the long-term support level of 5500 yuan/ton, and the cost side support was insufficient, leading to a decline in polyester filament prices. On August 15th, international crude oil futures rose, driving PX prices to rise synchronously, and the cost was transmitted to PTA, which gave a certain boost to the price of polyester filament. The expectation of the US Federal Reserve to cut interest rates in the next ten days and the Russia-Ukraine conflict and other factors led to a sharp rise in crude oil and the rise in the cost of polyester raw materials, driving up the price of polyester filaments.
Supply side: Polyester factories maintain a high operating rate of over 90%, but leading enterprises regulate the market through centralized production cuts. Coupled with limited new production capacity in August, the supply pressure is temporarily relieved, which provides some support for prices.
On the demand side: Terminal textile orders have not yet substantially rebounded, and weaving enterprises have high inventory of raw fabrics. The traditional off-season ends in mid to late August, and procurement is mainly based on essential needs. However, as the “Golden September and Silver October” approaches, there is a certain demand for stockpiling downstream. Since late August, there has been an increase in domestic and foreign trade orders, and the operating rate of downstream weaving factories has gradually rebounded to around 60%, which has driven the price of polyester filament. Manufacturers, in order to repair their profit margins, create expectations of price increases through continuous price hikes, forcing downstream customers to passively purchase goods. Downstream and end customers have cautious expectations for the future, with a clear wait-and-see attitude. However, during the process of price increases, they may also buy at low prices, causing market prices to fluctuate.

Business Society believes that cost support is expected to remain strong, coupled with traditional peak season demand expectations and the willingness of enterprises to raise prices, these factors may continue to drive prices upward. It is expected that there is a high possibility of strong fluctuations in the price of polyester filament in the short term.
