On June 24, the Chinese polyester filament yarn market experienced a brief surge in trading activity. According to publicly available industry data, the average sales-to-production ratio among sample enterprises jumped from 13.1% to 45.6%, a sequential increase of over 11 percentage points. On the surface, this appears to be a sign of recovery. However, a deeper dive into the data reveals a far less optimistic picture: among the 21 sample enterprises surveyed, 12 reported ratios below 40%, with seven of those falling under 30%. The average was pulled upward by a handful of companies that achieved ratios of 80% or even 150%. In other words, this rebound was not an industry-wide improvement but a pulse-like fluctuation driven by localized price wars.
Price Cuts: A Double-Edged Sword
The direct trigger for this sales spike was proactive price reductions by some factories. Faced with sustained pressure on polyester raw material costs and high inventory levels, manufacturers chose to offer discounts to generate cash flow. Market feedback indicates that these price cuts did temporarily stimulate purchasing interest among downstream weaving mills, particularly those with low inventories that took advantage of the lower prices to replenish stocks of standard polyester filament yarns. The problem, however, lies in the sustainability of such price-driven orders. Once the promotional period ends and prices rebound, buying enthusiasm quickly fades. Historical patterns confirm this: since 2025, the polyester filament yarn market has repeatedly experienced similar cycles of 'price cuts, volume surge, and volume contraction,' with each rebound becoming narrower, indicating a gradual weakening of underlying demand.
For manufacturers, while price cuts temporarily alleviate inventory pressure, they also compress already thin profit margins. The current spread between polyester filament yarn and its raw materials—PTA and MEG—is at multi-year lows. Further price reductions could push the industry into loss-making territory. Moreover, frequent price wars exacerbate the wait-and-see attitude among downstream users, creating a vicious cycle where buyers only purchase when prices drop.
Blocked Downstream Transmission: The Real Struggle at the Weaving End
The sluggish sales-to-production ratio is essentially a reflection of weak end-user demand transmitting upstream. Looking at the downstream end of the supply chain, weaving mills are not faring much better than their chemical fiber counterparts. Fabric orders are dominated by small, short-run batches, and overseas clients are aggressively negotiating prices down, making mills extremely cautious about raw material procurement. In China's major textile clusters—Shengze, Changxing, and Xiaoshao—comprehensive weaving machine operating rates hover between 60% and 70%, well below levels seen in previous years. This means that even if polyester filament yarn prices fall, downstream mills lack both the willingness and capacity for large-scale restocking.
Notably, the weakness in the chemical fiber market is not an isolated case. Other products in the polyester chain, such as polyester chips and polyester staple fiber, face similar sales and production pressures. The entire polyester supply chain is characterized by 'volatile costs, squeezed margins in the middle, and shrinking demand at the end.' This structural contradiction cannot be resolved through occasional price cuts.
Inventory and Costs: Key Variables for the Coming Weeks
Looking ahead, the direction of the polyester filament yarn market will depend on two core variables: factory inventory levels and upstream raw material price trends. Currently, industry inventories have climbed to a high of 20-30 days, with some large manufacturers facing particularly acute pressure. If there is no significant improvement in end-order demand, factories may be forced to continue cutting prices to destock, triggering a new round of price declines.
On the other hand, fluctuations in international oil prices and PTA prices will directly impact the cost support for polyester filament yarn. Recently, crude oil prices have been oscillating amid macro expectations and supply-demand dynamics, with PTA prices following suit. If raw material prices drop sharply, the price floor for polyester filament yarn may shift lower. Conversely, if raw materials stabilize or rebound, they could provide some bottom-line support for yarn prices. However, given the current weak demand environment, the pull from the cost side is limited. The market is more likely to exhibit an asymmetric pattern: 'when costs fall, product prices fall; when costs rise, product prices struggle to rise.'
