On July 7, 2026, the polyester staple fiber market sent a signal worth noting: the price gap between water treatment fiber balls and textile-grade staple fiber has widened to 8,500 RMB/ton. The former was quoted at 15,500 RMB/ton, while the latter only 7,000 RMB/ton. This data reveals an accelerating structural divergence within the industry—different downstream application scenarios are directly reshaping the pricing logic of staple fiber products.
Water Treatment Fiber: Independent Rally Driven by Policy Dividends
Fiber balls (standard specifications, diameter 30-50mm) maintained a firm quote of 15,500 RMB/ton, reported by water treatment material companies like Henan Kaijie. This price level has been running steadily, contrasting sharply with the trend of textile-grade staple fiber. The core driver is the continuous tightening of environmental policies requiring advanced industrial wastewater treatment. Since the implementation of the new Water Pollution Prevention and Control Action Plan in 2025, demand for fiber ball filter media from high water-consuming industries (petrochemical, printing/dyeing, papermaking) has maintained rigid growth, while supply side is constrained by raw material and processing technology barriers with limited new capacity. For the overall staple fiber industry, this means profit pools are shifting from conventional textile fields to functional and engineering applications.
Textile-grade Staple Fiber: Under Pressure at 7,000 RMB Threshold
In contrast to the firmness of fiber balls, textile-grade polyester staple fiber (1.56dtex×38mm, melt-spun cotton type) fell to 7,000 RMB/ton, reported by mainstream polyester enterprises like Huahong, delivered in Wuxi, Jiangsu—a traditional polyester industry cluster. The 7,000 RMB/ton price is approaching the average cash cost line of the industry, putting some high-cost facilities under loss pressure. This price reflects the reality that downstream textile end-demand recovery is weaker than expected—yarn mills and weaving factories generally maintain low raw material inventory strategies, purchasing on demand rather than stockpiling.
Industry Transmission Logic Behind the Price Scissors
The huge price gap between the two categories is not short-term fluctuation but a microcosm of long-term industrial trends. From the raw material side, both are based on polyester chips with limited cost differences, but terminal applications determine premium space. Water treatment fiber belongs to "policy-driven" demand, where users are relatively price-insensitive and more focused on product performance and stability. Textile-grade staple fiber is in the "consumption-driven" chain, significantly affected by garment export orders, domestic consumption confidence, and seasonal factors. Currently, global textile demand growth is sluggish, coupled with domestic overcapacity, and pricing power for textile-grade staple fiber is gradually shifting from producers to buyers.
Regional and Channel Concentration Signals
Notably, these price quotes are concentrated in two regions: Henan (water treatment fiber) and Wuxi, Jiangsu (textile-grade staple fiber). Henan, as a water treatment material processing base, leverages local mineral and chemical supporting industries to form a specialized cluster. Wuxi is a traditional polyester staple fiber production hub, gathering leading enterprises like Huahong. This geographical distribution indicates that specialization in the staple fiber industry is deepening, with production for different applications further concentrating in their respective advantageous regions, rather than a unified national market.
