6,950 RMB per ton versus 15,500 RMB per ton—these were the two extreme price tags in the polyester staple fiber market on July 6, 2026. The former was the quoted price for Huahong brand cotton-type PSF in Wuxi, while the latter was for Henan Kaijie's 50mm diameter fiber balls. Both fall under the polyester staple fiber category, but their vastly different applications create a price gap of more than double. This structural divergence reflects a deeper contradiction in the chemical fiber industry chain: industrial specialty fibers enjoy rigid demand, while conventional textile-grade products are caught between overcapacity and weak demand.
Cotton-Type PSF: Competition Logic Behind Brand and Regional Price Gaps
In the textile-grade cotton-type PSF segment (1.56dtex*38mm, melt direct spinning), data from July 6 reveals several key signals. Zhonglei brand in Huzhou quoted 7,370 RMB/ton, Xintuo brand in Xuzhou quoted 7,170-7,200 RMB/ton, Yida brand in Suqian quoted 7,150 RMB/ton, and Huahong brand in Wuxi had already fallen to 6,950-6,980 RMB/ton.
Geographically, Jiangsu (Xuzhou, Suqian, Wuxi) is the main supply region, with Zhejiang Huzhou also having capacity. The maximum price gap between brands reached 420 RMB/ton, not due to quality differences—all quotes are labeled as 'first-grade.' The real reasons lie in each company's cost control, inventory pressure, and sales strategy. Huahong is capturing market share with low prices, while Zhonglei maintains a relatively high position through brand premium or regional channel advantages.
What does this price divergence mean for buyers? When products of the same specification and grade differ by several hundred yuan per ton, cost-sensitive buyers in a weak demand environment will inevitably choose cheaper sources. This in turn pressures brands like Zhonglei and Yida to follow suit, creating a downward spiral.
Fiber Balls: Pricing Power of Specialized Demand
In stark contrast to the weakness of textile-grade PSF, water treatment fiber balls (standard grade) held steady at 15,500 RMB/ton, with all three specifications (30mm, 40mm, 50mm diameters) at the same price. This is more than double the price of cotton-type PSF.
Fiber balls are primarily used in industrial wastewater treatment and circulating water purification—a functional specialty material. Their high pricing logic is based on three factors: first, relatively high technical barriers requiring specific modification processes and stable physical structure; second, downstream clients (water treatment engineering companies, industrial plants) are less price-sensitive and more focused on filtration efficiency and service life; third, limited market capacity with concentrated supply, giving Henan Kaijie, the main quoter, pricing power.
From an industry transmission perspective, although both use polyester as raw material, the processing routes, performance requirements, and customer bases are completely different, and their price trends are nearly uncorrelated. This reminds industry investors that polyester staple fiber is not a single market—sub-sector prosperity varies greatly.
Regional Industrial Reactions and Procurement Strategy Adjustments
Based on delivery locations in the quotes, PSF trade flows show clear regional characteristics. Wuxi (Huahong), Suqian (Yida), and Xuzhou (Xintuo) are major cotton-type PSF production bases, with Huzhou (Zhonglei) as a supplementary supply node. These regions correspond to downstream industrial clusters—such as Nantong's home textiles, Shaoxing's printing and dyeing, and Changshu's garment industry—which are core consumption markets for PSF.
The continued decline in cotton-type PSF prices is a cost benefit for downstream textile enterprises, but buyers should be cautious about potential quality fluctuations as prices fall further. Some producers may lower process standards or use recycled materials near breakeven points. Buyers should strengthen incoming inspections, particularly for key indicators like fiber length and defect content.
For upstream PSF factories, the widening brand price gap signals an intensifying market share battle. Over the next one to two months, the industry is expected to see a shakeout: companies with weak cost control and high product homogeneity may be forced to cut production or shut down, while those with scale advantages or differentiated products (e.g., recycled PSF, functional fibers) will gain more room to survive.
