Polyester Filament Yarn Prices Stagnate: The 'Silent Period' of the Polyester Chain and Downstream Procurement Windows

The polyester filament yarn market is experiencing a rare 'full-scale freeze.' On May 14, prices for mainstream FDY and DTY specifications in the Changshu market remained unchanged from May 12. FDY 68D/24F was quoted at 9,700 yuan/ton, and DTY 150D/96F at 10,300 yuan/ton, with the price curve nearly flat. However, this does not signal stability—weak upstream polyester raw material prices are brewing under the surface, and the next round of industry chain games is shifting from 'silence' to 'divergence.'

Event Background

The core driver of this price stagnation is the weak transmission from upstream raw materials. The recent bearish performance of PTA and monoethylene glycol has directly squeezed cost support for polyester filament yarn. According to publicly available industry data, polyester plants in mid-May are generally facing the dual pressures of high inventory and thin margins, with little willingness to cut prices. Meanwhile, downstream weaving mills remain cautious about restocking due to unclear order books, leading to a 'weak supply and weak demand' stalemate.

From a product mix perspective, the price stability covers the entire range from fine denier to coarse denier, and from semi-dull to bright. Notably, previously volatile varieties such as DTY 75D/36F and DTY 150D/96F also showed no movement, reflecting draw-texturing mills' determination to hold prices, but also indicating that demand's acceptance of current prices is being tested.

Industry Impact

This 'silent period' means different things to different segments of the chain. For upstream polyester plants, raw material prices falling while product prices hold theoretically expands processing margins, but low actual transaction volumes mean profits cannot be converted into cash flow. Data shows that the polyester filament yarn production-sales ratio has recently hovered around 50-60%, with plant inventory pressures mounting.

For downstream weaving and draw-texturing mills, the current price plateau offers a relatively safe restocking window. If raw materials continue to weaken, polyester yarn prices will likely follow suit within one to two weeks. While procurement costs would then be lower, mills may face stampede risk under a 'buy on rising, not falling' mentality. Thus, the current price stability period is precisely a rational time for phased replenishment.

Practical Recommendations

For Buyers - Use the current price stagnation to restock in batches based on 1-2 weeks of consumption, avoiding the trap of waiting when raw materials fall further. - Focus on high-volume specifications like FDY 75D/36F and DTY 150D/96F, which have the highest price elasticity and will adjust first if raw materials decline.

For Export Enterprises - As current polyester yarn prices are at a mid-to-low level for the year, consider signing short-term price-lock agreements with long-term polyester plant partners to lock in raw material costs for export orders. - Monitor PTA futures trends. If raw material prices accelerate for two consecutive days or more, adopt a 'fast-in, fast-out' procurement strategy to leverage price volatility for higher export margins.
