On August 7, the polyester staple fiber market showed a rare price gap: filter balls for water treatment were quoted at 15,500 CNY/ton, while cotton-type staple for textiles was only 7,250 CNY/ton—a spread of 8,250 CNY/ton. This is not just a grade difference but reflects structural divergence in downstream applications: functional filter media and commodity textile raw materials are following completely different pricing logics.
Event Background
The quotes come from public industry platforms, involving two representative companies: Henan Kaijie Water Treatment Co. quoted filter balls (ordinary grade) in three specs (50mm, 40mm, 30mm diameter) all at 15,500 CNY/ton; Hebei Chujiao Supply Chain Co. quoted Huahong brand polyester staple (premium, 1.56dtex*38mm, melt direct spinning, cotton-type) at 7,250 CNY/ton. The former is produced in Zhengzhou, Henan; the latter in Wuxi, Jiangsu, both valid on that day.
Filter balls are not textile materials but water treatment media, typically made from polyester fibers, used in sewage treatment and oil-water separation. Their higher price stems from complex processing, high loss rates, and stable customer demand in the water treatment sector, which is less price-sensitive than textile mills.
In contrast, cotton-type staple at 7,250 CNY/ton is near recent lows. Melt direct spinning offers cost control, but weak end demand pressures inventories down the chain. The price difference between Wuxi and Zhengzhou also reflects regional supply-demand dynamics—East China has dense textile capacity, leading to fiercer competition.
Industry Impact
The doubled price gap means a 'fire and ice' situation within the polyester staple industry. For textile-use staple, 7,250 CNY/ton is close to cash cost for some plants; further declines could force small and medium direct-spinning units to cut production or halt. This would negatively feed back to upstream PX and PTA, further suppressing raw material prices.
For buyers, the current low consolidation of cotton-type staple is a double-edged sword: it lowers material costs but also signals insufficient downstream orders, risking inventory build-up. Foreign trade firms should be wary of a 'low-price trap'—if selling prices fall in tandem, margins may not improve.
The high price of filter balls sends a signal: differentiated, functional products command far higher premiums than commodities. In times of textile pressure, diversifying into industrial applications like water treatment could be a viable path for polyester firms. However, the filter ball market is limited and cannot absorb massive capacity shifts.
Regionally, stable quotes in Zhengzhou indicate a mature water treatment industry chain, while Wuxi, as a textile hub, serves as a national barometer. Watch for changes in East China plant operating rates; if production cuts expand, a rebound may occur by late Q3.
