The polyester filament yarn market is experiencing a sudden slowdown. According to industry data released on July 15, the average sales-to-production ratio of sampled enterprises stood at only 42.3%, a sharp drop of 24.7 percentage points from the previous trading day. This means that for every 100 tons of polyester filament produced that day, nearly 58 tons went into inventory rather than being consumed by downstream weaving factories.
What the Sales Data Reveals
A closer look at individual enterprise data shows significant divergence. The daily sales-to-production ratios ranged from 20% to 160%, but the vast majority of companies fell within the 20% to 40% range. Among the 24 sampled enterprises, only 4 had ratios above 50%, with one reaching 160%. The remaining 20 companies, or over 83%, reported ratios below 50%. This distribution indicates that the weak demand is an industry-wide phenomenon rather than an isolated issue.
It is noteworthy that the 160% outlier likely results from order backlogs or promotional strategies of a single firm, and does not signal a market recovery. Excluding this data point, the weighted average ratio would be even lower.
The Logic Behind Downstream Caution
The description of downstream users buying only for 'immediate needs' essentially reflects weaving factories' active destocking and shortening of raw material procurement cycles. Two factors drive this behavior: expectations of further price declines in polyester filament, and doubts about the sustainability of end-use garment orders.
On the cost side, upstream PTA and MEG prices have been oscillating within a narrow range, failing to provide clear direction for polyester filament. In such an environment, weaving factories prefer to buy only as needed, avoiding inventory risks. This strategy further suppresses raw material demand, creating a negative feedback loop for prices.
Direct Impact on Industrial Clusters
Polyester filament is a key intermediate in the chemical fiber supply chain, and its sales fluctuations directly affect textile clusters such as Shengze, Changxing, and Xiaoshan. The water-jet loom operating rates in these areas had already shown signs of weakening in June. If the polyester filament sales-to-production ratio remains below 50% for more than a week, weaving factories will likely further reduce operating rates, cutting raw material consumption. This would accelerate inventory buildup at chemical fiber plants, forcing price cuts.
Dual Pressure from Exports and Domestic Demand
The current weakness in the polyester filament market is not an isolated event. It is simultaneously affected by the relocation of export orders back to Southeast Asia and the lackluster recovery of domestic consumer demand. Customs data shows that textile and apparel export growth has slowed significantly in the first half of the year, while the domestic '618' e-commerce promotion failed to boost weaving factories' restocking enthusiasm.
This suggests that the market's expectation for the traditional 'golden September and silver October' peak season is being repriced. If sales data does not improve by late July, the industry may enter an inventory accumulation cycle ahead of schedule.
