The polyester staple fiber market is experiencing a tale of two extremes. On July 10, 2026, industry data showed water treatment fiber balls (30-50mm diameter) remained firm at 15,500 RMB/ton, while melt-blown cotton-type staple for spinning (1.56dtex*38mm) traded in a narrow range of 7,080-7,370 RMB/ton. The price spread of over 8,000 RMB/ton hit a new high this year. This structural divergence reflects distinct demand patterns, capacity mismatches, and cost transmission mechanisms.
Industrial Cluster Divergence: Jiangsu Spinning Capacity Under Pressure, Henan Water Treatment Demand Stable
From the data, supply of spinning-grade polyester staple is heavily concentrated in Jiangsu Province: Xintuo (Xuzhou) at 7,330 RMB/ton, Yida (Suqian) at 7,220 RMB/ton, Huahong (Wuxi) at 7,080 RMB/ton, and Huaxicun (Wuxi) at 7,370 RMB/ton. All use melt-blown technology and produce the same specification (1.56dtex*38mm cotton-type), mainly for cotton and blended mills. In contrast, Henan Kaijie, based in Zhengzhou, offers water treatment fiber balls in multiple sizes (30mm, 40mm, 50mm) but all at a uniform 15,500 RMB/ton, indicating rigid demand from the water treatment sector.
What does this mean? Jiangsu, as the main polyester staple production base, faces capacity concentration and slowing downstream textile and apparel exports, dragging down spinning-grade prices. Meanwhile, Henan's water treatment fiber balls, as industrial consumables, benefit from stable environmental policy-driven demand and low price sensitivity. This regional cluster divergence is directly reflected in the price gap: Jiangsu spinning-grade prices are over 50% lower than water treatment grades.
Cost Transmission: How Raw Material Fluctuations Impact Different Categories
The main raw materials for polyester staple are PTA and MEG. Recently, PTA prices have fluctuated with crude oil, staying in the 5,500-5,800 RMB/ton range. For spinning-grade producers, raw material costs account for about 75%. Current selling prices of 7,080-7,370 RMB/ton mean processing margins have been compressed to near break-even or loss levels. Taking Huahong's 7,080 RMB/ton offer, after deducting PTA and MEG costs, the processing margin is only about 1,500 RMB/ton, below the industry average of 1,800-2,000 RMB/ton.
In contrast, water treatment fiber balls use the same raw material but undergo secondary processing (e.g., crimping, heat setting), significantly adding value. Henan Kaijie's 15,500 RMB/ton price includes high processing margins, and downstream customers are mostly water treatment engineering firms with long procurement cycles and low price elasticity. This asymmetry in cost transmission further widens the price gap.
Practical Implications for Buyers and Exporters
For spinners, current staple prices are at a year-low, but further downside risk remains. Buyers should monitor PTA futures and polyester plant operating rates, and consider increasing inventory when prices dip below 7,000 RMB/ton. Quarterly contracts with Jiangsu producers could also lock in costs.
For Buyers - Closely track the PTA-polyester staple spread; when it narrows to below 1,500 RMB/ton, it may signal a short-term bottom, prompting timely restocking. - For water treatment fiber balls, given price rigidity and concentrated supply (Henan Kaijie as regional leader), consider signing annual framework agreements early to avoid supply disruptions during peak seasons. - Compare offers across brands (Xintuo, Yida, Huahong, Huaxicun); Huahong's 7,080 RMB/ton is competitive but requires quality verification.
For Exporters - For spinning-grade polyester staple exports, consider pricing 5-8% below domestic levels to compete in Southeast Asian markets. Current domestic prices are near cost, limiting further discounts. - Water treatment fiber balls, as high-value products, can target Middle Eastern and African water treatment projects, leveraging a 30-40% price advantage over European alternatives.
Conclusion
The price divergence in polyester staple fiber is essentially a microcosm of overcapacity and evolving demand structure. Spinning-grade staple faces homogeneous competition and weak downstream demand, while water treatment fiber balls maintain high margins through technical barriers and rigid demand. This trend is unlikely to reverse in the near term. All chain participants must adjust strategies: buyers should strengthen cost control, exporters focus on high-value categories, and producers accelerate product differentiation to avoid a low-price race to the bottom.
