Price trend:

Last week (November 3, 2025 - November 7, 2025), polyester filament prices showed an upward trend, influenced by multiple factors. On November 3, some polyester factories slightly increased polyester filament prices by 50 RMB/ton. On November 4, some polyester factories raised polyester filament prices by 50-100 RMB/ton. On November 5, some polyester factories raised prices for certain specifications of polyester filament by another 50-100 RMB/ton. According to data from SunSirs, as of November 7, mainstream polyester filament factories in Jiangsu and Zhejiang quoted POY (150D/48F) at 6,500-6,700 RMB/ton, polyester DTY (150D/48F low elasticity) at 7,750-8,000 RMB/ton, and polyester FDY (150D/96F) at 6,750-6,900 RMB/ton.

Analysis review

Strengthening cost support: Due to losses, PTA companies had actually begun to suspend production. For example, Xinfengming was expected to suspend 2.2 million tons last week, and Tongkun planned to upgrade its 1.8 million tons of technology. This made the bottom of PTA relatively clear. If the plans are implemented in a coordinated manner, processing fees are expected to recover, thus supporting the price of polyester filament.

Demand was boosted: During the "Double Eleven" shopping festival in China, e-commerce platforms began rushing to buy and ship goods starting from October 20. At the same time, the weather in some parts of China suddenly turned to winter, leading to a surge in demand for seasonal clothing and textiles. The inventory of raw fabrics such as fleece and abrasive fabrics was quickly depleted, and weaving factories concentrated on purchasing raw materials, which boosted the demand for polyester filament.

Favorable policy and macroeconomic factors: Following the meeting between China and the US in Busan, South Korea on October 30, the Ministry of Commerce announced that the two countries had reached several important consensuses in their trade negotiations, including postponing various tariffs for another year. This reduced costs for textile companies, increased market demand, and facilitated inventory reduction and price stabilization for polyester filament manufacturers. Furthermore, the Ministry of Industry and Information Technology held a symposium on the polyester industry to prevent and mitigate cutthroat competition in the refined paradicarboxylic acid (PTA) and bottle-grade polyester chip industries, which also boosted market sentiment.

Improved market sentiment: As market conditions improved, polyester manufacturers had adjusted their prices from time to time in order to seize market share. Some companies were more willing to hold prices, which had improved market sentiment and had also supported polyester filament prices to some extent.

Market Forecast:

Overall, SunSirs predicts that polyester filament prices will mainly fluctuate in the short term, with a possibility of a slight upward trend.
