On July 7, 2026, the average sales-to-production ratio of polyester filament yarn sample enterprises stood at only 42.9%, a sharp drop of 29 percentage points from the previous trading day. This figure means that for every 100 tons produced, fewer than 43 tons were absorbed by the market. Downstream buying sentiment has hit a freezing point, and the chemical fiber market is experiencing a demand-side chill.
The Industrial Signal Behind the Numbers
Data from 23 sample enterprises reveals extreme divergence. The highest ratio reached 200%, but the vast majority fell between 20% and 45%. Only two companies achieved ratios above 100%, both through price concessions to balance sales. In contrast, 11 companies recorded ratios below 30%, with the lowest at just 10%. This pattern of 'a few hot, most cold' indicates structural differentiation rather than an overall downturn.
More notably, the ratio plummeted from 71.9% on July 6 to 42.9% on July 7—a 29-percentage-point drop in a single day. Such volatility is unusual in the polyester filament yarn market and typically signals a sudden demand contraction or a break in procurement rhythm. Combined with public industry data showing that the comprehensive operating rate of looms in Jiangsu and Zhejiang has fallen from 70% in early June to about 65%, it points to weakening terminal textile orders transmitting upstream.
Transmission Logic: From Weaving to Chemical Fiber
The immediate downstream of polyester filament yarn is weaving enterprises, whose fabrics ultimately feed apparel, home textiles, and industrial textiles. Since the second quarter of 2026, global textile retail growth has slowed, and destocking cycles in major European and American markets remain incomplete, leading to a year-on-year decline in export orders. Domestically, the summer fabric restocking pace has been significantly weaker than in previous years due to fluctuating consumer confidence.
Weaving enterprises face a 'two-sided squeeze': upstream raw material costs remain high due to crude oil and PTA support, while downstream customers demand price cuts. With profit margins compressed, weavers have responded by reducing raw material procurement frequency and inventory days. The sharp decline in July 7 data is a direct reflection of this 'buy-as-you-use, stop-as-you-go' tactic.
On the cost side, international crude oil prices hovered around $75/barrel, and PTA spot prices consolidated near 5,800 yuan/ton. Raw material costs have not loosened significantly, meaning polyester filament yarn producers' cost pressure will not ease soon. The combination of plunging sales ratios and rigid costs will accelerate inventory accumulation. Public data shows that as of July 7, social inventories had climbed to about 25 days, up 5 days from mid-June. If inventories breach the 30-day warning line, companies may be forced to accelerate production cuts or price reductions.
Market Reactions and Regional Dynamics
Geographically, enterprises in major production areas like Xiaoshan and Shaoxing in Zhejiang, and Shengze and Wuyang in Jiangsu, showed clear divergence. Some leading companies maintained relatively stable shipments through differentiated products (e.g., cationic dyeable, flame-retardant, antibacterial yarns), while conventional POY, FDY, and DTY varieties faced severe overstock. This reflects a structural shift among downstream weavers toward higher-value-added fabrics, reducing demand for standard chemical fiber raw materials.
Traders in the Shengze area reported that market inquiries on July 7 fell about 40% from the previous week, with actual transactions limited to small urgent orders. Weavers generally kept raw material inventories at extremely low levels of 5-7 days, unwilling to take any stocking risk. If this 'zero inventory' strategy becomes industry consensus, it will significantly weaken the pricing power of polyester filament yarn producers.
