The polyester staple fiber market is experiencing a subtle price divergence: fiber ball varieties remain rock-solid at 15,500 RMB/ton in Zhengzhou, Henan, while cotton-type varieties show a 290 RMB/ton brand spread across multiple industrial zones in Jiangsu. Behind this lies the interplay of demand resilience in different application fields and regional supply-demand dynamics.
Fiber Balls: Rigid Water Treatment Demand Supports High Prices
On July 10, 2026, fiber ball (regular) quotes stood out prominently. Henan Kaijie Water Treatment Co., Ltd. uniformly quoted 15,500 RMB/ton for diameters of 30mm, 40mm, and 50mm, delivered in Zhengzhou. This price level far exceeds that of cotton-type polyester staple fiber, reflecting the special attributes of fiber balls as water treatment filter media—they require high material stability, corrosion resistance, and filtration efficiency. Downstream customers are mostly environmental engineering firms and industrial water treatment companies, with rigid demand and relatively low price elasticity.
Notably, fiber ball prices have remained in a high range since early 2026, closely tied to tightening environmental policies and rising industrial wastewater treatment standards. For water treatment procurement departments, while current quotes are high, the likelihood of a significant price drop in the short term is low, considering equipment operation cycles and maintenance costs.
Cotton-Type Varieties: Regional Price Gaps Offer Sourcing Opportunities
Unlike fiber balls, cotton-type polyester staple fiber (1.56dtex*38mm, melt direct spinning) shows clear price divergence across Jiangsu's industrial zones. According to quotes from Hebei Chujiao Supply Chain Management Co., Ltd., Huahong brand (Wuxi) reported 7,080 RMB/ton, Yida brand (Suqian) 7,220 RMB/ton, and Xintuo brand (Xuzhou) 7,330 RMB/ton; Zhejiang Tianchen Textile Supply Chain Co., Ltd. offered Huaxicun brand (Wuxi) at 7,370 RMB/ton. The maximum brand spread reaches 290 RMB/ton, uncommon in the highly standardized polyester staple fiber market.
- Wuxi, a traditional textile hub, has two brands—Huahong and Huaxicun—in the same location but with a 290 RMB/ton gap, likely due to brand positioning, capacity scale, and customer structure.
- Xuzhou-based Xintuo has the highest quote, possibly linked to its capacity utilization, transport costs, and regional order conditions.
- Suqian-based Yida's mid-range quote reflects the gradual improvement of the textile supply chain in northern Jiangsu and its cost advantages.
For buyers, the current market is in a traditional textile off-season, with downstream yarn mills operating at low rates and weak demand for cotton-type polyester staple fiber, creating a window for low-cost procurement. The Huahong brand in Wuxi, with the lowest quote, may be a priority for enterprises needing inventory replenishment.
Industry Chain Transmission: Raw Materials vs. Downstream Orders
The price divergence in cotton-type polyester staple fiber essentially results from a three-way game between upstream raw material costs, midstream capacity release, and downstream order demand. On the raw material side, recent PTA (purified terephthalic acid) and MEG (monoethylene glycol) prices have been stable, but PX (para-xylene) supply stability remains a concern. On the capacity side, melt direct spinning polyester staple fiber capacity is highly concentrated, with leading enterprises in Jiangsu and Zhejiang directly impacting market supply. On the demand side, the textile and apparel industry enters a summer off-season, with yarn mills showing weak restocking intentions, pressuring cotton-type variety prices.
The resilience of fiber ball prices signals to the market: when overall textile industry growth slows, specialized products in niche segments (like environmental water treatment) can command higher pricing power. This trend may prompt more polyester staple fiber enterprises to increase R&D in differentiated products, reducing reliance on conventional cotton-type varieties.
