On July 15, the polyester filament yarn market transaction data flashed a red light. Industry public data shows that the average sales-to-production ratio of sample enterprises was only 42.3%, a sharp drop of 24.7 percentage points from the previous trading day. This figure means that nearly 60% of production capacity failed to translate into effective sales, with inventory backlog risks rapidly accumulating.
Signals Behind the Data
Looking at detailed data, the day's sales-to-production ratio showed extreme divergence. Among the 23 sample enterprises listed, one achieved a ratio as high as 160%, while others recorded zero. Most enterprises were concentrated in the 20% to 40% range, indicating severely insufficient market absorption capacity. The few high-ratio cases likely resulted from localized clearance through price cuts or extended payment terms, not a sign of demand recovery.
This 'ice and fire' situation precisely illustrates the lack of consensus expectations in the current market. Downstream weaving enterprises generally adopt a wait-and-see approach, only making small batch replenishments when prices show clear concessions. The average of 42.3% is approaching the industry's recognized 'warning line'—when the ratio continuously falls below 50%, polyester plants' inventory turnover pressure will force production cuts or price reductions.
Industry Chain Transmission: From Filament to Fabric
Polyester filament yarn is the core raw material for chemical fiber fabrics, and its sales ratio directly reflects the willingness of downstream weaving enterprises to operate. The current 42.3% ratio means weaving enterprises are actively reducing raw material inventory. Behind this 'de-stocking' behavior is the anticipation of persistently weak terminal garment orders.
From the industry chain perspective, upstream PTA and ethylene glycol prices have recently maintained volatility, offering no clear directional guidance. However, the contraction in demand is more lethal—weaving enterprises face high finished fabric inventory and tight cash flow, forcing them to reduce operating rates. According to industry public data, the comprehensive loom operating rate in the Jiangsu-Zhejiang region has dropped about 5 percentage points from its second-quarter peak, further suppressing demand for polyester filament.
For polyester plants, the low sales ratio presents a dilemma: either cut production to support prices, or reduce prices to move volume. Current industry operating rates remain high. If price-cutting strategies are initiated, it could trigger a new round of price wars, squeezing profit margins across the entire industry chain.
Procurement Psychology and Inventory Cycle Game
The downstream users' 'wait-and-see attitude with rigid procurement' is essentially a game of inventory cycles. Weaving enterprises believe raw material prices still have room to fall, so they delay purchases. This mentality is particularly prominent in the July off-season—high temperatures cause some factories to limit power usage or adopt staggered production, terminal orders enter a window of inactivity, and raw material procurement naturally shrinks.
However, it is worth noting that individual enterprises achieved a sales ratio of 160%, indicating not all buyers are waiting. This demand may come from:
- Rigid replenishment for previous order deliveries
- Specific demand for differentiated varieties
- Strategic stockpiling using low-price windows
This divergence reminds the market: structural opportunities still exist amid overall weakness. For polyester filament suppliers, relying solely on price cuts cannot sustainably activate demand. The key lies in helping downstream customers identify true order rhythms and offering more flexible payment terms or price lock-in services.
