On July 6, 2026, the polyester staple fiber market witnessed an unusual price gap: water treatment fiber balls were quoted at a stable 15,500 RMB/ton, while cotton-type spinning fibers traded in a range of 6,950 to 7,370 RMB/ton, creating a spread of over 8,500 RMB/ton. This data, sourced from industry public quotation platforms, highlights extreme price divergence within the same product category driven by end-use differentiation.
Industrial Logic Behind the Price Divergence
The high price of water treatment fiber balls is no short-term fluctuation. Henan Kaijie, a representative producer, uniformly quoted 15,500 RMB/ton for its 30-50mm diameter fiber balls, up about 12% year-on-year. These products are primarily used in industrial wastewater filtration and oilfield produced water treatment, with demand boosted by stricter environmental regulations and increased industrial water treatment investment. In contrast, spinning-grade polyester staple fiber prices remain weak: Zhonglei (Huzhou, Zhejiang) at 7,370 RMB/ton, Xintuo (Xuzhou, Jiangsu) at 7,170-7,200 RMB/ton, Yida (Suqian, Jiangsu) at 7,150 RMB/ton, and Huahong (Wuxi, Jiangsu) as low as 6,950 RMB/ton. The price gap among different brands also reaches 420 RMB/ton, reflecting intense competition and squeezed margins in the spinning segment.
Regional and Brand Price Gradients
From the detailed quotations, Huahong in Wuxi, Jiangsu offers the lowest price (6,950 RMB/ton), while Zhonglei in Huzhou, Zhejiang commands the highest (7,370 RMB/ton). This regional disparity correlates with raw material costs, logistics expenses, and local supply-demand dynamics. Jiangsu, as a major polyester staple fiber production base, has high capacity concentration, forcing mills to cut prices to secure orders. Zhejiang's Huzhou, by contrast, benefits from proximity to downstream textile clusters (e.g., Shaoxing, Xiaoshan), where demand is more stable, providing stronger price support. Notably, even the same brand (e.g., Huahong) shows minor price differences of 30 RMB/ton between different traders (Hebei Chujiao, Baoding Nawei), indicating decent market liquidity but an overall buyer's market.
Demand Pressure on the Spinning Side
Cotton-type polyester staple fiber prices generally below 7,200 RMB/ton have approached or fallen below production costs for some small and medium manufacturers. Combined with recent fluctuations in raw material PTA prices, processing margins for polyester staple fiber are further compressed. Downstream spinning mills operate at around 70% capacity, as final garment orders remain sluggish due to slow overseas inventory destocking, limiting procurement to small, just-in-time orders. This demand structure makes it difficult for polyester staple fiber prices to stage an effective rebound, and they are expected to oscillate around 7,000 RMB/ton in the near term.
Independent Trend for Industrial Fibers
In stark contrast to spinning-grade fibers, water treatment fiber balls have charted an independent upward trajectory. Their pricing anchor has decoupled from the polyester supply-demand framework and is now more tied to environmental engineering project bidding cycles and industrial water treatment equipment renewal. The current 15,500 RMB/ton quote is roughly 1,500 RMB/ton higher than the same period in 2024, and supply is concentrated among a few players (e.g., Henan Kaijie), giving them stronger bargaining power. This structural divergence suggests that for traders involved in both spinning and industrial fibers, adjusting product portfolios toward higher-value industrial fibers may be a more optimal strategy.
