In early August 2026, the polyester staple fiber market presented a rare price gap: water treatment fiber balls were quoted as high as 15,500 CNY/ton, while cotton-type melt-blown staple fiber was only 7,250 CNY/ton, a spread exceeding 113%. This divergence is not accidental; it reveals deep structural differences in demand within the polyester supply chain and reminds buyers to re-examine product specifications and pricing logic.
Background
According to public industry data, on August 7, Henan Kaijie Water Treatment Co., Ltd. quoted ordinary fiber balls (diameter 50mm, 40mm, 30mm) uniformly at 15,500 CNY/ton, with delivery in Zhengzhou, Henan. Meanwhile, Hebei Chujiao Supply Chain Management Co., Ltd., acting as an agent for the Huahong brand polyester staple fiber (first-grade, 1.56dtex*38mm, melt-blown cotton-type), quoted only 7,250 CNY/ton in Wuxi, Jiangsu. Both products fall under the same broad category of polyester staple fiber, but their uses and processing routes differ sharply, leading to a huge price disparity.
Fiber balls are typically made from polyester fibers through heat setting into spherical shapes for water treatment filtration. They are industrial consumables requiring high wear resistance and corrosion resistance, with a relatively small market and strong supplier pricing power. Cotton-type staple fiber, on the other hand, is mainly used for spinning and nonwovens, with abundant capacity and intense competition, making its price closer to polyester raw material costs. Thus, the multiple-fold price gap essentially reflects the different pricing logic between industrial specialty products and bulk textile commodities.
Industrial Impact
This price spread deserves attention for its transmission along the textile chain. For regular polyester staple fiber buyers, the 7,250 CNY/ton quote implies relatively low raw material costs, helping to ease cost pressure for spinners, especially pure polyester yarn and blended yarn factories, which may see short-term margin improvement. However, low prices often accompany ample supply; if polyester raw material prices fluctuate, staple fiber quotes could rebound quickly.
For specialty products like water treatment fiber balls, the high price of 15,500 CNY/ton reflects stable demand in the industrial filtration market. Purchases in water treatment and environmental engineering are typically project-based, with low price sensitivity but high requirements for consistent quality and supply capability. Henan Kaijie's quote may become a reference point for similar products in the central region, prompting nearby water treatment companies to reassess procurement budgets.
Geographically, the price difference between Wuxi and Zhengzhou also hints at supply-demand conditions in different industrial belts. Wuxi, located in the Yangtze River Delta textile cluster, has active polyester staple fiber trading, with prices closer to the market average; Zhengzhou, serving more industrial product markets, operates a relatively independent pricing system. Cross-regional procurement must factor in logistics costs and lead times.
