The Wangjiangjing polyester yarn market ended July with a price table frozen across the board, marking a temporary pause in the seasonal game of the polyester chain. According to public market data, from July 28 to 30, 2026, all major categories—FDY, POY, and DTY—showed zero price movement, with ex-factory prices identical to two days prior. This rare zero-volatility is not a sign of balanced supply and demand, but a classic symptom of a market lacking momentum on both sides.
Price Freeze: The Market Enters a 'Steady-State Game'
Looking at specific categories, in the FDY semi-dull series, 50D/24F traded steadily in the 9,500-9,650 yuan/ton range, with quotes highly consistent across origins. 75D/36F hovered between 9,050-9,100 yuan/ton, while 150D/96F concentrated in the 8,450-8,550 yuan/ton band. The POY series showed no movement either, with 50D/48F at 8,800-8,900 yuan/ton and 75D/96F unchanged at 8,700 yuan/ton. DTY prices were fully frozen, with 75D/36F at 10,050-10,100 yuan/ton and 150D/48F between 9,440-9,500 yuan/ton.
This 'zero-spread' scenario implies that both polyester mills and downstream weaving mills are in a state of heightened wait-and-see. Upstream raw materials—PTA and MEG—have shown recent weakness, providing unstable cost support. Meanwhile, downstream weaving orders have not seen concentrated release, leading to only just-in-time replenishment purchases of polyester yarn, with no bulk stockpiling intent.
FDY 75D/144F: A Structural Bright Spot in a Narrow Band
Amid the broad weakness, one specification deserves attention. Industry feedback indicates that FDY 75D/144F has maintained decent sales recently. This differentiated fiber product has relatively rigid demand due to its specific applications in imitation silk and high-density fabrics. In contrast, purchasing power for DTY 150D/144F was notably weaker, reflecting shrinking demand for conventional low-stretch yarns in the end market.
This structural divergence reveals a trend: when overall demand is tepid, specifications with differentiated functions or specific application scenarios tend to show better 'downside resilience.' For weaving mills, whether they adjust their product mix toward high-count, high-density, fine-denier products will directly impact their raw material procurement costs and final product competitiveness.
Outlook: Consolidation Likely, but Downside Limited
Based on upstream raw material trends and downstream operating rates, the short-term outlook for polyester filament yarn is likely a 'consolidation and adjustment' pattern. While polyester mill inventories are building, they have not yet reached a critical point requiring aggressive price cuts for destocking. Downstream grey fabric inventories are also at moderate levels, and weaving mill operating rates remain stable, providing a floor of rigid demand for raw materials.
This implies that prices are unlikely to rise (lacking cost-driven or demand-driven catalysts) but also unlikely to fall deeply (supported by rigid demand). For industry participants, patience is the key virtue now—waiting for the next catalytic factor, whether it be cost volatility in polyester raw materials or the seasonal recovery in textile and apparel orders.
