Polyester Staple Fiber Price Divergence: Fiber Balls Stay High, Cotton-Type Under Pressure

The price gap between fiber balls and cotton-type polyester staple fiber has widened to nearly 8,000 yuan per ton, reflecting two distinct industrial logics.

Price Divergence and Industrial Logic

Public industry quotes on June 5, 2026, show ordinary fiber balls (30-50mm diameter) uniformly priced at 15,500 yuan/ton, supplied by Henan Kaijie Water Treatment Co., Ltd. in Zhengzhou. Meanwhile, cotton-type polyester staple fiber (1.56dtex*38mm, melt direct spinning) ranges from 7,690 to 7,840 yuan/ton, covering brands such as Xintuo (Xuzhou), Sanfangxiang (Wuxi), Yida (Suqian), Huahong (Wuxi), and Huaxicun (Wuxi).

The high plateau of fiber ball prices is no accident. Water treatment demand for fiber balls is rigid—they are irreplaceable as filter media in industrial and municipal wastewater treatment, and the supplier base is concentrated. In contrast, the pressure on cotton-type staple fiber prices directly reflects weak textile end-demand. National Bureau of Statistics data shows that textile capacity utilization in Q1 2026 fell about 2 percentage points year-on-year, with downstream yarn and grey fabric sectors reluctant to build inventory.

Regional and Brand Competition

Geographically, the three major polyester staple fiber clusters in Jiangsu—Xuzhou, Wuxi, and Suqian—show highly convergent quotes around 7,800 yuan/ton. However, Huahong's brand quotes 7,690 yuan/ton, about 100-150 yuan/ton below the mainstream. This discount suggests Huahong may be pursuing aggressive destocking or benefiting from superior raw material cost control. For buyers, this opens a short-term bargaining window.

Notably, Baoding Nawell New Material Technology Co., Ltd. acts as a unified trader representing all five brands. This centralized procurement model allows downstream customers to compare prices easily, intensifying brand competition.

Chain Transmission and Outlook

Cotton-type staple fiber prices are approaching the breakeven point for some small and medium mills. Based on current PTA prices (around 5,800 yuan/ton) and processing costs, the 7,690 yuan/ton quote leaves a processing margin of less than 300 yuan/ton. If end-order weakness persists, regional production cuts or maintenance shutdowns may occur.

Meanwhile, the high profit margin of fiber balls (relative to raw material costs) is attracting more players to this niche. However, the water treatment market is limited in size, and fiber ball production requires specific processes and certifications, so a flood of new entrants is unlikely in the short term.

Practical Recommendations

For Buyers - For cotton-type staple fiber, consider Huahong's 7,690 yuan/ton offer—it is the most competitive among major brands, but verify quality consistency. - For fiber balls, lock in long-term contracts; the supplier base is concentrated and prices are unlikely to soften soon.

For Mills - With cotton-type margins under pressure, consider adjusting product mix toward fiber balls or differentiated fibers (e.g., hollow, antibacterial). - Monitor PTA price trends; if feedstock prices fall, replenish inventory opportunistically to lower costs.
