In mid-May 2026, the Wangjiangjing polyester filament market delivered a report card of stable prices across the board, but transaction volumes did not expand accordingly. From May 12 to 14, major specifications including FDY, POY, and DTY all saw zero price movement in their ex-factory quotes. This rare sideways movement is not a sign of market equilibrium but rather a collective wait-and-see attitude before a directional move.
Market Analysis: Stuck Between Support and Resistance
Looking at specific prices, FDY semi-dull 50D/24F from multiple mainstream producers remained in the 9,900-10,100 yuan/ton range, while FDY bright 50D/24F stayed at 10,250 yuan/ton. POY 150D/48F from Xinfengming was quoted at 8,800 yuan/ton, and DTY 150D/48F from Rongsheng Chemical Fiber stood at 10,200 yuan/ton. The price difference across all specifications over two trading days was zero. This price rigidity indicates, on one hand, that upstream costs provide some support at current levels, and on the other hand, that end-user demand lacks the momentum to drive further increases.
A notable structural divergence exists among varieties. FDY 75D/144F was flagged as having “decent sales,” while DTY 150D/48F was described as having “weak buying interest.” This disparity suggests that weaving mills are not operating at a uniform pace or restocking rhythm—differentiated products with finer denier and higher filament counts still enjoy some demand resilience, while inventory pressure for conventional specifications may be building.
Upstream Transmission and Downstream Game
The trend in polyester raw materials is a key variable for this market. Public data shows that PTA and ethylene glycol have recently exhibited a weak and volatile pattern, with cost support for polyester filament gradually weakening. However, polyester filament prices have not followed the raw materials downward, opting instead for a “sideways resistance.” This reflects an intense game between polyester factories’ willingness to hold prices and weaving mills’ desire to push them down.
For weaving mills, current polyester yarn prices are at relatively high levels, and further restocking would mean increased capital occupation and risk exposure. Especially against an uncertain backdrop for export orders, most factories prefer to maintain just-in-time procurement and reduce raw material inventories. On the polyester factory side, due to low inventory levels and supply contraction from some plant maintenance, there is little incentive to cut prices in the short term. This “you don’t move, I don’t move” deadlock is the truest portrayal of the current Wangjiangjing market.
Outlook: Adjustment More Likely Than Breakout
Combining upstream raw material trends with downstream demand realities, the polyester filament market is likely to enter an adjustment phase. Specifically, there are two possible evolution paths:
- Path 1: If raw materials continue to weaken, polyester factories’ ability to hold prices will gradually erode, leading to a moderate price correction of 100-200 yuan/ton.
- Path 2: If downstream weaving operating rates experience an unexpected drop before the summer slack season, demand collapse could force accelerated price declines, with POY and DTY likely falling more than FDY.
Based on currently available data, Path 1 appears more probable. Export data for textiles and apparel has not yet shown significant deterioration, and the domestic market maintains some resilience. However, buyers should not ignore the risk of Path 2, especially given current inventory levels are not low.
