On August 1, the polyester filament market saw a sudden cooling in transactions, with the average sales-to-production ratio of sample enterprises dropping to 33.6%, down 3.8 percentage points from the previous trading day. This data reveals a demand vacuum after the weekend restocking spree and signals that polyester filament prices may face renewed downward pressure in the short term.
Signals Behind the Data
According to public sales data, performance varied significantly among enterprises: some achieved sales-to-production ratios as high as 60%, while others fell to 0%, with the majority clustering between 20% and 40%. This polarization is not accidental; it reflects a clear shift in downstream weaving enterprises' procurement strategies—they are no longer hoarding blindly but replenishing precisely based on their own order situations.
The sales-to-production ratio, as a core indicator of industry prosperity, its sharp decline means that inventory pressure on polyester filament enterprises is re-accumulating. The overdraft effect of weekend restocking, coupled with weak terminal demand, has left the market in a wait-and-see mood early this week. For polyester plants, this makes it harder to maintain prices, and some may have to resort to discounts to relieve inventory pressure.
Industrial Impact and Transmission Logic
The fluctuation in polyester filament sales-to-production ratio directly affects the demand expectations for upstream PTA and MEG. Currently, the polyester sector maintains high operating rates, but downstream weaving enterprises have relatively sufficient raw material inventories, lacking short-term replenishment momentum. If this pattern of "high operating rate, low sales" persists for several weeks, it will force polyester plants to cut production or reduce prices, thereby transmitting price pressure to the raw material end.
From a regional industrial cluster perspective, weaving enterprises in major consumption areas such as Shengze and Changxing are mainly digesting existing inventories after the concentrated procurement in late July. Some small and medium-sized weaving factories report limited growth in new orders, maintaining a just-in-time procurement strategy for raw materials. This cautious attitude is fully reflected in the early August sales data.
It is worth noting that the divergence in sales-to-production ratios also reflects differences in bargaining power among enterprises of different scales. Large polyester plants, relying on stable customer relationships, have relatively higher ratios; while small and medium plants are more susceptible to market fluctuations, with lower ratios. This structural divergence may further intensify industry consolidation.
