The polyester filament yarn market received a clear cooling signal in early July 2026. On July 3, Rongsheng Petrochemical (including Shengyuan Petrochemical) reduced prices for selected polyester DTY specifications by 100 to 200 CNY/ton. While the cut is not drastic, given Rongsheng's position as a core supplier in the industry, the move's directional significance deserves attention across the supply chain.
Meanwhile, on July 2, the polyester staple fiber main contract (2609) on the Zhengzhou Commodity Exchange fell by 136 CNY/ton, with a notable increase in short positions. The combination of these two signals suggests that sentiment across the polyester sector is turning bearish.
Background
The price adjustment covers multiple DTY specifications. According to public data, 75/36 low-elastic DTY is quoted at 10,050 CNY/ton, 100/96 light mesh at 9,900, 120/192F micro mesh at 9,550, 150/48 low-elastic at 9,150, 150/96 low-elastic at 9,100, 300/96 low-elastic at 8,900, 300/96 light mesh at 8,900, and 300/96 heavy mesh at 9,250.
The price gradient between fine-denier and coarse-denier specifications remains reasonable, but the reduction range of 100-200 CNY/ton indicates this is not a panic sell-off but a proactive concession based on order and inventory pressure.
Industry data gives a bearish score of -1, categorized as "moderately negative." This assessment is relatively restrained, but combined with the futures market decline, it constitutes dual pressure on spot prices.
Industrial Impact
Polyester DTY is a key raw material for downstream weaving, mainly used in producing imitation silk and elastic fabrics. As a leading supplier, Rongsheng's price adjustments often serve as a bellwether. This cut directly reflects insufficient end-order support.
- For DTY spot prices: Short-term bearish, but the decline is limited; other suppliers are expected to follow, likely within 200 CNY/ton.
- For overall polyester filament: Supply-demand dynamics are weak, downstream purchasing enthusiasm is low, and weaving mills may delay restocking, further suppressing market activity.
- For polyester staple fiber: The sentiment spillover is clear; increased short positions in futures imply market pessimism about staple fiber, though its downstream applications (nonwovens, fillings) differ from filament, making the impact indirect.
From a chain transmission perspective, upstream PX and PTA prices have remained stable recently, suggesting that this price cut primarily reflects weak demand from end-use sectors like apparel and home textiles. The expected peak-season rebound in foreign trade orders did not materialize at the end of Q2 2026, which is the core reason behind the price reduction.
