The cotton-type polyester staple fiber market is undergoing a quiet reshuffling. Public industry data from July 3, 2026, clearly outlines the current divergence: mainstream cotton-type products (1.56dtex*38mm) range from 6,940 CNY/ton for the Huahong brand to 7,320 CNY/ton for the Zhonglei brand, a spread of 380 CNY/ton. Meanwhile, specialty fiber balls (30-50mm diameter) remain rock-solid at 15,500 CNY/ton, nearly double the price of cotton-type fibers.
Cotton-Type Polyester Staple Fiber: Brand Competition Amid Overcapacity
The price range for cotton-type polyester staple fiber is not simply a low plateau. Huahong brand quotes 6,940 CNY/ton, Yida follows at 7,150 CNY/ton, Xintuo at 7,200 CNY/ton, and Zhonglei leads at 7,320 CNY/ton. This gradient indicates that brand premium and product consistency are becoming key pricing variables in an oversupplied environment.
Geographically, the quoted production capacity is concentrated in Jiangsu and Zhejiang provinces. Huahong is in Wuxi, Yida in Suqian, Xintuo in Xuzhou, and Zhonglei in Huzhou. These are mature industrial clusters within a few hundred kilometers of each other, making logistics cost differences negligible. Thus, the brand spread primarily reflects differences in product quality, customer loyalty, and sales strategy.
For downstream spinning mills, the 6,940 CNY/ton Huahong price means raw material costs are at a multi-year low. If sustained, this will directly improve profit margins for mid- to low-end yarns but may also intensify price competition. Buyers should be cautious: low prices may come with quality volatility, as some mills might cut raw material grades to maintain price advantages.
Specialty Fiber Balls: A High-Barrier Price Island
In stark contrast to the fierce competition in cotton-type products, specialty fiber balls (ordinary grade) remain fixed at 15,500 CNY/ton. Henan Kaijie Water Treatment Co., Ltd., the sole quoter, offers diameters of 30mm, 40mm, and 50mm at identical prices. This reflects the rigid demand for industrial water treatment applications and a relatively concentrated supply structure.
Fiber balls are used in wastewater filtration as industrial consumables. Their customers—water treatment engineering firms and industrial plants—require specific physical properties (compression resistance, corrosion resistance) and face high switching costs. The price has remained stable, indicating a balanced equilibrium between supply and demand.
For polyester staple fiber mills looking to enter this niche, the high price signals attractive margins, but technical barriers are significant. Fiber ball production requires specialized equipment and formulations, plus customer certification testing.
Transmission Effects of Price Divergence on the Chain
The price gap between cotton-type and specialty fibers is essentially a tale of two market structures. Cotton-type products have many players, overcapacity, and high commoditization, leading to price competition. Specialty fibers, however, exhibit oligopolistic or monopolistic competition with much fatter margins.
This divergence is already impacting the chain. Low cotton-type prices will encourage downstream textile mills to increase polyester substitution in blends, replacing higher-cost cotton or viscose. Meanwhile, high margins in specialty fibers may attract leading mills to invest more in R&D and pivot toward higher-value industrial fiber applications.
From an export perspective, low cotton-type prices boost Chinese products' competitiveness in international markets, especially Southeast Asia and South Asia. However, the sustainability of this low-price strategy is questionable—if PTA raw material prices rebound, margins will be squeezed rapidly.
