On the morning of July 7, the spot price of polyester staple fiber in Jiangsu settled at 7,185 yuan per ton, up 35 yuan from the previous trading day. This figure may seem unremarkable—a 35-yuan increase is hardly a storm in the chemical fiber market. But when viewed alongside the narrow negotiation range of 7,130-7,200 yuan per ton, a low of 6,950 yuan, and a high of 7,300 yuan, it tells a deeper story: the staple fiber market is engaged in a tug-of-war between supply and demand, and this rebound may signal the end of bottom testing.
The Industrial Logic Behind the Price Rebound
A 35-yuan per ton increase would have been negligible in past years when swings of hundreds or even thousands of yuan were common. But this rebound occurs in Jiangsu, a core production hub for polyester staple fiber. Jiangsu, Zhejiang, and Fujian together account for over 70% of national capacity, making Jiangsu's spot quotes a key barometer for the entire industry.
The price structure reveals a spread of 250 yuan between the mainstream negotiation range of 7,130-7,200 yuan and the low quote of 6,950 yuan. This gap, far wider than normal, indicates market fragmentation: some mills are clearing inventory at low prices, while others are testing higher levels. The emergence of a high quote of 7,300 yuan further suggests that some suppliers hold short-term bullish expectations.
This divergence stems from the recent stabilization of upstream PTA and MEG prices. With feedstock prices no longer falling, staple fiber mills have gained confidence to raise prices. However, downstream weaving and texturing firms remain cautious, placing only small, need-based orders and avoiding stockpiling. This means the 35-yuan rise is more cost-driven than demand-led.
Ripple Effects Across the Industrial Belt
The rebound in Jiangsu's staple fiber spot price is transmitting both upstream and downstream. For upstream PTA plants, higher staple fiber prices mean improved margins in the polyester segment, potentially delaying production cuts. For downstream weaving mills, especially in clusters like Shengze and Nantong, rising raw material costs will directly squeeze gray fabric margins.
Take Shengze as an example: local water-jet loom utilization has dropped from 85% at the start of the year to around 70% currently. If staple fiber prices continue to rebound, weavers face a dilemma: accept higher costs and further compress profits, or cut output and wait for prices to retreat. This stalemate is unlikely to break soon, as final garment orders show no clear recovery.
For foreign trade firms, while the 35-yuan increase is modest, combined with yuan exchange rate volatility and shipping cost uncertainty, export price competitiveness could be subtly eroded. This is especially critical for staple fiber exports to Southeast Asia, where price elasticity is extremely low and any cost increase may undermine order advantages.
Short-Term Outlook and Actionable Recommendations
Overall, this rebound is a technical correction and does not signal a trend reversal. Two key constraints remain: first, the polyester capacity overhang persists, with national staple fiber operating rates still above 75%, keeping supply pressure high; second, end-user demand is weak, with textile and apparel export growth slowing and domestic markets showing no improvement.
Thus, over the next 1-2 weeks, Jiangsu staple fiber spot prices are likely to oscillate within the 7,100-7,250 yuan per ton range. If PTA prices strengthen further, a test of 7,300 yuan is possible; conversely, if crude oil prices fall or downstream restocking ends, prices could slip back below 7,000 yuan.
