A polyester filament run rate of 30-40% says more about the market than price movements alone. Between September 12 and 13, the light textile raw material markets in Shengze and Jiaxing presented a contradictory picture: most polyester plants kept quotes stable, with a few even raising prices slightly, yet downstream invoicing volumes remained notably low. Weavers and texturizers turned cautious. This divergence between production and sales often signals an impending directional shift.
Product Divergence: Fine Denier and Dull Yarns Outperform
Data from China Customs and industry sources indicate this is not broad weakness but intensifying structural divergence. FDY fine denier yarns stood out, with bright FDY 30D/24F moving actively, mainly for polyester-cotton blend fabrics. Dull FDY outperformed semi-dull and bright varieties, with 40D/48F seeing decent downstream demand, supported by high-density polyester taffeta and lining fabrics. FDY 48D/48F quotes clustered between 10,650 and 10,800 yuan per ton, with the price gap between mills narrowing significantly, suggesting pricing power is concentrating among leading suppliers.
By contrast, conventional coarse DTY network yarns remained weak, bright DTY flat yarns traded quietly, and differentiated cationic yarns saw limited volume. On the POY side, texturizers continued small-volume replenishment, with 150D/144F quoted around 9,650 yuan per ton in cash, while intermingled POY sales stayed soft. The takeaway for buyers: bargaining room for commodity-grade items is shrinking, while supply elasticity for functional and fine denier products is lower. Locking in volumes early is more practical than pressing for price cuts.
The Tug-of-War Between Inventory and Operating Rates
Water-jet loom operating rates are being maintained, but weavers and texturizers hold low polyester filament inventories. This means downstream demand is not absent; rather, uncertainty over raw material prices is keeping buyers from chasing highs. Polyester plants themselves carry low filament inventories, providing a hard floor under prices.
Why hasn't low inventory translated into immediate price hikes? The answer lies in the low run rate. An invoicing level of 30-40% means physical throughput is slower than production, forcing plants to balance price support against inventory drawdown. A short-term upward correction in polyester filament cannot be ruled out, but its magnitude depends on whether weaving orders materialize before the National Day holiday. For mills, this is a window to lock in processing margins; for traders, the risk-reward of chasing prices is unfavorable.
The yarn market shows a similar pattern of stability with divergence. Cotton yarn sales were steady, with 21s and 32s moving well, the latter mainly for air-jet fancy fabrics. Poly-cotton 65/35 held steady, while 80/10 and 90/10 edged up, and 80/20 45s saw decent volume. Poly-viscose prices stayed flat with limited volume, though 40s showed momentum. Pure polyester yarn remained firm, with 1.56*38 cotton-type polyester staple centered below 8,700 yuan per ton, its price center slightly higher.
In rayon yarn, 10s traded noticeably better than other counts, prices adjusted steadily, and viscose staple held around 14,500 yuan per ton. Rayon yarn is expected to face downward adjustment pressure, as the tug-of-war between viscose staple cost support and weak downstream demand intensifies. For mills focused on rayon yarn, locking in viscose staple procurement costs early is more pragmatic than waiting for a price rebound.
Supply Chain Transmission and Procurement Strategy
The coexistence of low polyester filament inventory and low run rates essentially mirrors downstream doubts about the strength of the peak season. Weavers dare not stockpile because visibility on end-use apparel orders is limited; polyester plants are reluctant to cut prices because their own inventory pressure is manageable. This standoff typically breaks in one of two ways: either end-use orders release beyond expectations, driving run rates higher, or weaving production cuts force raw material prices lower.
For buyers, product-specific strategies are warranted. For tight-supply items like fine denier FDY and dull yarns, moderate early stocking is advisable. For conventional coarse DTY and intermingled POY, bargaining room is relatively larger, and just-in-time procurement can be maintained. For exporters, RMB exchange rate fluctuations and ocean freight changes remain the primary profit variables. Minor raw material adjustments are not yet enough to alter quotation strategies, but if polyester filament rises significantly before month-end, timely communication with overseas customers about repricing windows becomes necessary.
