On June 5, 2026, the latest polyester staple fiber quotations revealed a structural phenomenon worth attention: the price gap between fiber balls and cotton-type polyester staple fiber has widened to nearly 8,000 RMB/ton. The former remained stable at 15,500 RMB/ton, while the latter ranged only between 7,690 and 7,840 RMB/ton. Such a stark divergence is not a short-term fluctuation but a direct reflection of demand and supply differentiation across end-use sectors.
Variety Divergence: The Logic Behind Fiber Ball vs. Cotton-Type Staple Fiber Pricing
Fiber balls, primarily used as water treatment fillers, are specialty functional products with high requirements for raw material purity and diameter uniformity (30-50mm). Their market capacity is relatively limited, giving suppliers stronger bargaining power. The latest quotation shows that Henan Kaijie maintained its price of 15,500 RMB/ton across all three specifications (30mm, 40mm, 50mm), reflecting rigid demand in water treatment and concentrated supply.
In contrast, cotton-type polyester staple fiber (1.56dtex*38mm), a key raw material for spinning and nonwovens, has numerous market participants and intense competition. The quotations for different brands varied significantly: Huahong offered the lowest at 7,690 RMB/ton; Xintuo and Yida both at 7,840 RMB/ton; Huaxicun at 7,810 RMB/ton; and Sanfangxiang at 7,800 RMB/ton. The maximum brand-to-brand spread reached 150 RMB/ton, reflecting differences in cost control, inventory pressure, and sales strategies.
Regional and Brand Dynamics: Pricing Power Shift in Jiangsu's Industrial Belt
Geographically, cotton-type staple fiber quotations clustered in three Jiangsu cities: Xuzhou (Xintuo, 7,840 RMB/ton), Suqian (Yida, 7,840 RMB/ton), and Wuxi (Sanfangxiang, Huahong, Huaxicun, 7,690-7,810 RMB/ton). Wuxi, as a traditional chemical fiber cluster, showed clear internal divergence: Huahong became the lowest at 7,690 RMB/ton, while Huaxicun and Sanfangxiang quoted 7,810 and 7,800 RMB/ton respectively. This intra-regional spread suggests that inventory levels and order backlogs, not just raw material costs, are driving pricing decisions.
For buyers, this means more bargaining room in Wuxi, while suppliers in Xuzhou and Suqian show stronger price consistency. If the spread persists, some spinning mills may adjust their procurement radius, shifting more orders toward lower-priced regions.
Chain Transmission: Diverging Cost Pressures on Spinning and Nonwoven Mills
Cotton-type staple fiber prices hovering in the 7,700-7,800 RMB/ton range imply relatively low raw material costs for downstream spinners. However, a 150 RMB/ton difference between brands accounts for about 2% of yarn processing costs—enough to impact profit margins. Mills targeting mid-to-low-end yarns may choose Huahong to save costs, while those requiring higher quality may prefer Xintuo or Yida.
The high price of fiber balls, however, pressures water treatment engineering companies' budgets. At 15,500 RMB/ton, the cost per ton of fiber balls is more than double that of cotton-type staple fiber. If water treatment projects rely on fiber ball fillers, material costs will rise significantly, potentially driving some projects toward alternative fillers or domestic fiber balls.
