The price gap between cotton-type polyester staple fiber and fiber balls, exceeding 8,000 CNY per ton, stood out sharply in the publicly available industry quotes on July 10, 2026. While mainstream cotton-type products hovered around 7,000 CNY per ton, water-treatment fiber balls remained at 15,500 CNY per ton. This structural divergence reflects uneven demand across textile chemical fiber sub-sectors.
Cotton-Type Varieties: Under Pressure with Clear Regional Supply
On that day, quotes for cotton-type polyester staple fiber (1.56dtex*38mm, melt-spun, first grade) clustered between 7,080 and 7,370 CNY per ton. Specifically, Huahong brand was quoted at 7,080, Huaxicun at 7,370, Yida at 7,220, and Xintuo at 7,330. All four quotes came from traders, with delivery points concentrated in Jiangsu Province—Wuxi, Suqian, and Xuzhou serving as major supply hubs.
This price range represents a notable decline from the 2026 first-half average. The continuous release of melt-spun capacity is the core factor suppressing prices. Jiangsu, as a traditional production base, shows a narrow spread of only 290 CNY per ton among brands, indicating intense competition and limited buyer bargaining power.
For downstream spinning mills, current prices mean raw material costs are at a year-to-date low. However, if polyester raw materials like PTA and MEG rebound, short-fiber prices may quickly follow. The current low-price window is unlikely to last.
Fiber Balls: Premium Logic for Niche Products
In stark contrast, Henan Kaijie Water Treatment Co., Ltd. quoted ordinary fiber balls at 15,500 CNY per ton, with three sizes (30mm, 40mm, 50mm) at the same price. Fiber balls are used mainly in water treatment filtration, requiring specialized production processes and formulations, making costs far higher than conventional spinning-grade staple fiber.
The 15,500 CNY price represents a premium of over 110% compared to cotton-type varieties. This reflects value-added functionality—water treatment demands high chemical resistance and filtration precision, with a concentrated supplier base and project-based procurement cycles. Henan Kaijie's quote serves as a strong benchmark for this niche.
However, the uniform pricing across three sizes suggests a balanced supply-demand equilibrium. If downstream environmental project tenders accelerate, prices may rise; otherwise, there is room for negotiation.
Supply Chain Dynamics and Procurement Timing
From a value-chain perspective, polyester staple fiber remains in an overcapacity cycle. The scale advantage of melt-spun technology keeps mainstream prices under long-term pressure. Fiber balls, with their technical barriers and specific applications, can sustain higher margins.
For buyers, differentiated strategies are needed:
- Cotton-type: Prices are relatively low, but monitor PTA trends. If PTA stabilizes, consider increasing inventory; if raw materials continue to fall, stick to demand-based purchases.
- Fiber balls: The high price reflects scarcity, but verify supplier qualifications and certifications. Direct contact with source factories like Henan Kaijie is recommended to avoid intermediary markups.
For foreign trade firms, the international price gap for cotton-type short fiber is narrowing. Southeast Asia's self-sufficiency is rising, so China's export advantage lies more in quality consistency than price. Fiber balls, however, still have export potential in European and American water treatment projects due to technical barriers.
