On July 15, 2026, the polyester staple fiber market saw an unusual price divergence: within the same product category, the gap between industrial-grade and textile-grade varieties reached nearly 8,000 RMB/ton. This is not a short-term fluctuation but a direct reflection of structural changes in downstream demand.
The Logic Behind Price Divergence
According to the day's quotation data, industrial-grade fiber balls (standard) held firm at 15,500 RMB/ton in Zhengzhou, Henan, while textile-grade cotton-type polyester staple fiber (1.56dtex*38mm) was quoted at 7,650 RMB/ton in Huzhou, Zhejiang, and only 7,370 RMB/ton in Wuxi, Jiangsu. The price gap has surged from the historical average of 3,000-4,000 RMB/ton to nearly 8,000 RMB/ton.
Industrial-grade fiber balls are primarily used in water treatment and air filtration. Their price rigidity stems from the rigid demand brought by tightening environmental regulations. In the first half of 2026, upgraded industrial wastewater discharge standards in multiple regions drove a 15% year-on-year increase in filter media procurement. In contrast, textile-grade polyester staple fiber faces dual pressures: weak end-consumption in apparel and weaving mill operating rates below 70%, causing prices to slide from 8,200 RMB/ton at the start of the year.
Regional and Supply Chain Ripple Effects
Geographically, industrial-grade fiber ball production is concentrated in Henan, where a local water treatment industry cluster provides stable localized orders, insulating prices from external shocks. Textile-grade quotations are centered in Jiangsu and Zhejiang—Huzhou and Wuxi are both core areas of textile fabric clusters. Huzhou's higher quotation of 7,650 RMB/ton versus Wuxi's 7,370 RMB/ton reflects differences in inventory levels and customer mix: Huzhou mills rely more on filament yarn orders, allowing slightly higher short-fiber premiums, while Wuxi quotations more closely track actual cotton market transaction prices.
This price divergence triggers a chain reaction across the supply chain:
- Upstream PTA and MEG suppliers face a choice: prioritize supply to industrial-grade staple fiber plants or continue to textile-grade mills?
- Midstream producers are forced to adjust product lines; some have begun shifting melt-direct spinning capacity from cotton-type staple fiber to industrial-grade fiber balls.
- Downstream weavers and traders are accelerating destocking amid wait-and-see sentiment; cotton-type staple fiber social inventory in Jiangsu and Zhejiang has risen to 45 days of consumption.
Key Variables for Future Price Trends
In the short term, industrial-grade fiber ball prices will likely remain high, but two risk factors warrant attention: first, water treatment project tenders may slow in the second half of the year; second, if polyester chip costs weaken with crude oil, cost support will erode. The bottom for textile-grade polyester staple fiber is not yet clear; the key is the start of autumn/winter garment orders—if foreign trade orders fail to pick up by late August, prices may fall below 7,200 RMB/ton.
Over the medium to long term, the polyester staple fiber industry is undergoing structural adjustment. High margins in industrial-grade products are attracting more capacity, while textile-grade products must rely on differentiation (e.g., recycled polyester, functional staple fiber) to escape homogeneous competition. For buyers, this divergence presents both risk and opportunity.
