On July 7, polyester filament yarn prices in Changshu showed a systemic softening. In the FDY series, mainstream specifications such as 68D/24F, 75D/36F, and 100D/48F declined by 50 to 100 CNY per ton, with Tongkun Group's 68D/24F quoted at 8,900 CNY/ton, down 100 CNY from two days earlier. DTY grades including 75D/36F and 150D/144F also dropped 100 CNY/ton, while a few specifications such as 100D/36F and 150D/96F held steady for certain brands. Overall trading volumes remained "average," with no signs of a volume surge despite the price cuts.
This price movement occurred against a backdrop of volatile rebounds in upstream polyester raw materials. In theory, rising costs of PTA and MEG should support downstream polyester filament prices. However, the actual market reaction shows a divergence: raw materials rose while polyester filament fell. This indicates that pricing power has temporarily shifted from the cost side to the demand side.
Weak Demand Is the Core Issue
Changshu and its surrounding areas are key polyester processing and weaving clusters in China. Price changes here often foreshadow the real supply-demand dynamics of the broader Jiangsu-Zhejiang textile chain. The price adjustments involved major players such as Rongsheng Petrochemical, Tongkun Group, Xinfengming, Tiansheng Chemical Fiber, and Jiabao New Fiber, with reductions concentrated in the 50-100 CNY/ton range—a moderate but broad-based correction. This "general adjustment" rather than selective discounts suggests industry-wide demand contraction rather than individual inventory pressure.
Downstream texturing and weaving mills have fundamentally shifted their restocking mindset. Against a backdrop of tepid end-apparel orders and slow inventory digestion in overseas markets, weavers prefer to maintain low raw material inventories and purchase on a need-to basis. Even small price drops fail to trigger significant bargain buying, as the market anticipates further price weakness ahead.
Why the Cost Rebound Fails to Propel Prices
The recent rebound in polyester raw materials is mainly driven by crude oil fluctuations and some plant maintenance—short-term supply disruptions rather than demand-led trends. Polyester filament producers share this assessment: the sustainability of the raw material rebound is questionable, and blindly following it upward would risk larger inventory depreciation if raw materials fall again. Therefore, most polyester filament plants chose to prioritize destocking over price hikes.
This pattern of "rising costs, falling products" historically occurs during periods of midstream overcapacity combined with downstream demand weakness. Currently, polyester filament operating rates remain high, while weaving sector operating rates have begun seasonal declines. Supply-demand mismatch is the fundamental reason for price pressure.
Ripple Effects Across Regional Industrial Clusters
The price easing in Changshu is expected to quickly spread to neighboring textile clusters such as Shengze, Xiaoshan, and Shaoxing. Shengze, China's largest chemical fiber fabric production base, is highly sensitive to changes in polyester filament costs. If polyester filament prices continue to weaken, grey fabric quotes may also soften, further squeezing weavers' profit margins.
For export-oriented companies, lower polyester filament prices mean reduced costs for exported fabrics, theoretically aiding order acquisition—but only if overseas buyers have clear replenishment needs. Currently, European and American markets remain in a destocking phase, and the pace of order回流 from Southeast Asia has slowed. Whether cost advantages translate into actual orders still depends on the recovery of end-consumer demand.
