Polyester Filament Market Maintains Firm Trajectory: Price Hikes, Inventory Improvement, And Demand Outlook Drive Momentum
Aug 28, 2025
Recent weeks have seen the polyester filament market trend steadily upward, with many mainstream manufacturers rolling out sequential price increases. Since entering August, the market has kicked off a consistent uptrend-on key dates including August 11, 12, 13, 20, 21, and 26, leading producers announced a 50 RMB/ton price hike each time. These moves have not only boosted market confidence but also pushed overall quotations steadily higher, marking a notable shift from the earlier flat or cautious sentiment.
Cost Support: PTA's Strength Lays a Solid Foundation
A critical driver behind polyester filament's firmness lies in its core raw material-PTA (Purified Terephthalic Acid)-which has maintained a strong price trajectory recently. Currently, PTA trades in the range of 4,850 to 4,870 RMB/ton, with two key factors underpinning this stability. First, strong prices of PX (Para-Xylene), the upstream feedstock for PTA, have provided direct cost support, limiting room for PTA price declines. Second, several major PTA producers have announced maintenance schedules in the coming weeks; this expected reduction in supply is further shoring up PTA's market position, which in turn translates to steady cost support for polyester filament.
Supply Side: Joint Production Cuts Ease Overcapacity Pressures
Prior to the recent price uptick, leading polyester filament manufacturers took coordinated action to reduce production, a move aimed at balancing market supply and demand amid earlier oversupply concerns. This proactive adjustment not only alleviated excess inventory pressures but also prevented price volatility caused by overproduction. Industry insiders note that while production has gradually normalized, the residual effect of these cuts-namely, more balanced supply-demand dynamics-continues to support polyester filament prices, preventing sharp downturns even as demand slowly recovers.
Demand Outlook: "Golden September & Silver October" and Policy Tailwinds Fuel Optimism
On the demand front, signs of recovery are emerging. The operating rate of downstream weaving enterprises (a key consumer of polyester filament) has edged up slightly in recent weeks, as manufacturers begin preparing for the traditional "Golden September & Silver October" peak season-when textile and apparel demand typically surges. Segments like Oxford cloth (used in bags and outdoor gear) and luggage fabric have already shown stronger performance, with order volumes picking up.
Additionally, policy news has added to positive sentiment: the U.S. recently extended the window for certain tariff rates on Chinese textile exports by 90 days. This extension eases near-term uncertainty for exporters and is expected to support overseas demand for polyester filament-based products, further bolstering market expectations.
Inventory: A Noticeable Improvement Eases Pressure
Inventory levels, a key barometer of market health, have also improved significantly. Latest data shows that inventory days for POY (Partially Oriented Yarn) stand at around 22 days, FDY (Fully Drawn Yarn) at approximately 25 days, and DTY (Draw Textured Yarn) at roughly 34 days-all marking a clear decline from earlier periods. This inventory digestion has reduced pressure on manufacturers and strengthened their willingness to maintain stable or slightly higher prices, rather than engaging in price wars to clear stock.
Outlook: Short-Term Firmness Likely, With Demand as the Key Watchpoint
Looking ahead, industry analysts expect polyester filament to maintain its firm trajectory in the short term. Cost support from PTA is likely to remain robust, while the approaching peak season and positive export policy signals will continue to underpin demand expectations. Manufacturers' strong resolve to keep prices stable also reduces downside risks. However, the market will still closely monitor whether downstream weaving demand can materialize as expected-any shortfall in actual orders could temper the upward momentum.
As a raw material supplier for the apparel and home textile industries, we provide high-quality polyester filament (including POY, FDY, DTY) and nylon filament-products widely used in downstream segments like Oxford cloth and luggage fabric that are showing strong demand ahead of the "Golden September & Silver October" season. For enterprises preparing to capitalize on the peak season's demand, we can support stable raw material supply to align with market dynamics.
