On June 30, 2026, polyester filament yarn prices in Wangjiangjing market, Jiaxing, Zhejiang, saw a systematic decline, with FDY, POY, and DTY categories dropping broadly by 100 to 200 yuan per ton. The FDY 150D/36F specification recorded the steepest fall, with major suppliers including Xinfengming, Rongsheng Chemical Fiber, and Tiansheng Chemical Fiber cutting prices by 200 yuan per ton to a range of 8,200-8,400 yuan per ton. This adjustment is not an isolated event but a clear reflection of upstream inventory pressure transmitting through the supply chain.
Breadth and Depth of Price Adjustments
In the FDY semi-dull series, the 50D/24F specification from Rongsheng, Jiabao, and Tiansheng all fell by 100 yuan per ton to 9,200-9,300 yuan per ton. The 68D/24F grade dropped uniformly by 100 yuan per ton across suppliers including Rongsheng, Zhejiang Hengyi, Xinfengming, Zhejiang Tongkun, Tiansheng, and Changshu Chemical Fiber. The FDY bright series also faced pressure, with Rongsheng's 50D/24F down 50 yuan per ton and Jiabao's 50D/36F down 100 yuan per ton.
The POY series saw more aggressive cuts. The 75D/96F specification from Jiatong, Shenjiu, Shenghong, and Xiaoshan Senkai all dropped by 200 yuan per ton to 8,400-8,450 yuan per ton. In the DTY segment, conventional grades such as 75D/36F from Jiangsu Taicang and Xinfengming fell by 200 yuan per ton to 10,000 and 10,100 yuan per ton respectively. Notably, DTY 150D/48F and 150D/96F remained stable, indicating relatively steady demand for heavy-denier products.
Volume Growth Amid Falling Prices
Industry data shows polyester filament yarn sales volumes have increased recently, but prices have simultaneously declined. This apparent paradox reflects a market undergoing inventory destocking through price-for-volume trades. Upstream polyester feedstock support remains weak, with PTA and MEG prices lacking upward momentum, leaving no cost floor for filament prices.
For downstream weaving mills, the current price downtrend makes procurement decisions more cautious. Falling raw material prices discourage stockpiling, encouraging just-in-time buying. Moreover, price decline expectations accelerate inventory depreciation, further compressing margins in the weaving segment. As a major polyester filament distribution hub in the Jiangsu-Zhejiang region, Wangjiangjing's price movements often serve as a bellwether.
Regional Industry Belt Response and Supply Chain Transmission
The Jiaxing-Suzhou textile belt, where Wangjiangjing is located, hosts some of the densest polyester filament and weaving capacity in China. This price adjustment involves over ten major suppliers including Rongsheng, Tongkun, Xinfengming, Shenghong, Tiansheng, Jiabao, and Hengyi, spanning both Zhejiang and Jiangsu provinces. The broad-based, multi-specification simultaneous cuts indicate widespread inventory pressure among upstream mills.
By product category, FDY 75D/144F still sees decent sales, while DTY 150D/144F faces weak buying interest. This structural divergence suggests demand for fine-denier, multi-filament products remains relatively supported, but market absorption capacity for conventional heavy-denier items is weakening. This nuance deserves close attention from buyers.
Outlook: Consolidation Remains the Theme
Looking ahead, a trend reversal for polyester filament yarn appears unlikely in the near term. Upstream feedstock lacks clear direction, downstream weaving mill operating rates may face seasonal declines, and end-user apparel export orders remain uncertain. Prices will likely continue oscillating in a low range. For buyers, this is not a time to blindly bottom-fish, but opportunities exist for phased replenishment on oversold items.
