The thermometer of the chemical fiber market—the sales-to-production ratio—is clearly signaling a cool-down. On June 22, the average sales-to-production ratio of polyester filament yarn sample enterprises stood at only 39.5%, a mere 1.3 percentage point increase from the previous trading day. Behind this figure lies a collective cautious stance among downstream users and a persistent contraction in spot market transaction volumes.
Supply-Demand Imbalance Behind the Numbers
A ratio of 39.5% means that more than 60% of the industry's daily capacity failed to convert into actual sales. What is more concerning is that this slight recovery came from an already low base—the market shows no spontaneous rebound momentum.
Looking at individual sample firms, the disparity is stark: the highest recorded ratio was 120%, while the lowest was 0%. More than half of the enterprises reported ratios below 30%, indicating that weak demand is not an isolated phenomenon but an industry-wide challenge.
This structural weakness is directly tied to the shift in procurement strategy among downstream weaving mills. When end-demand from apparel and home textiles grows sluggishly, fabric mills tend to compress raw material inventories, maintaining only essential purchases and no longer buying on price fluctuations.
How Downstream Caution Reshapes Market Rhythm
The core contradiction in the polyester filament yarn market has shifted from "whether upstream can support prices" to "when downstream will re-enter the market."
In past years, chemical fiber factories routinely used joint production cuts to push prices higher, forcing downstream mills to stock up ahead of price hikes. But the current market environment has fundamentally changed:
- End-consumption growth has slowed, shortening fabric mills' own order cycles
- Volatility in polyester raw materials PTA and MEG has narrowed, removing the leverage for price coercion
- Downstream capital chains are tight, favoring zero or low inventory operations
The failure of the "buy on rising prices" logic means upstream factories must rethink pricing strategies. Relying solely on production cuts to support prices, amid real demand contraction, will only accelerate market share loss.
Three Key Nodes in the Transmission Chain
The first node is the polyester plant. Persistently low sales ratios will force plants to either increase maintenance shutdowns or cut prices outright. But the room for price cuts is constrained by raw material costs—if PTA prices weaken simultaneously, polyester filament yarn margins will compress more sharply.
The second node is the weaving mill. The current low raw material price window presents an opportunity for well-capitalized firms to build inventory. But most small and medium-sized mills are more concerned about the sustainability of their own orders than the level of raw material prices.
The third node is the trader. As market lubricants, traders tend to stay on the sidelines or even short when sales ratios are low, further compressing spot liquidity and creating a negative feedback loop: low sales ratio → weak trader hoarding → even lower sales ratio.
