Price trend:

In November 2025, the price of polyester filament yarn showed a fluctuating trend, initially rising, then stabilizing, and finally weakening. From the beginning to the middle of the month, prices rose slightly due to cost support, with consecutive price adjustments on the 3rd, 7th, and 11th. Mainstream varieties such as POY 150D/48F saw an increase of approximately 1.5%-1.9% by the 11th. From the 17th to the 21st, prices remained generally stable, with some manufacturers unable to sustain further increases after making adjustments. After the middle of the month, the upward trend stalled and became stable. In the latter half of the month, the upward trend completely stopped, showing a weaker trend due to declining demand, with only a few differentiated varieties maintaining relatively stable prices.Prices weakened in the latter part of the month due to weak demand. As of November 28th, the mainstream polyester filament yarn factories in Jiangsu and Zhejiang quoted POY (150D/48F) at 6,500-6,700 RMB/ton, DTY (150D/48F low elasticity) at 7,750-8,000 RMB/ton, and FDY (150D/96F) at 6,750-6,900 RMB/ton.

Market Analysis

Cost-side support was initially strong but weakened later: At the beginning of the month, rising international oil prices, coupled with maintenance shutdowns at several PTA plants including Sichuan Energy Investment, led to tight supply, causing PTA prices to rise steadily and providing strong cost support for polyester filament, driving up its prices. However, in the middle and latter half of the month, crude oil prices corrected downwards, ethylene glycol prices continued to weaken, hitting a new low for the year, and PTA prices also slightly declined, weakening overall support from raw materials and removing the cost basis for continued price increases in polyester filament.

Supply-side pressure was manageable but an increase in supply is expected: This month, the operating rate of the polyester filament industry reached approximately 87.59%. Although the restart of facilities such as Jinqiao's plant led to a slight increase in supply, overall industry inventory remained at a moderately low level. POY factory inventories were mostly maintained at less than half a month's supply, and polyester factories had reached a tacit agreement to avoid price wars, preventing prices from falling sharply. However, two new plants with a combined capacity of 600,000 tons/year would come into operation at the end of the month, and the subsequent increase in supply will further pressure the market.

Weak demand was the main drag: At the beginning of the month, the operating rate of textile mills in Jiangsu and Zhejiang reached 76.5%, with winter order deliveries driving a temporary increase in demand. However, after the middle of the month, winter orders were completed, and "Double Eleven" orders were delivered, resulting in insufficient new orders. The operating rate of chemical fiber textile mills in Jiangsu and Zhejiang dropped to 67.7%, and the production-to-sales ratio mostly remained at 30-50%. Furthermore, the positive impact of India's cancellation of relevant certifications on exports was limited, and weak end-user demand made it difficult for polyester filament to maintain its upward trend, even facing downward pressure.

Market Forecast:

Overall, SunSirs believes that the polyester filament market is expected to remain weak in the short term. After mid-December, with the further delivery of end-user orders, the industry inventory levels are at a medium-to-low level, which to some extent limits the potential for a significant price drop.
