The 39.1% figure is not just a number—it represents the average sales-to-output ratio of sample polyester filament enterprises, down 0.7 percentage points from the previous trading day. What makes this decline noteworthy is its timing: it emerged precisely when most filament producers raised their quotations. When prices rise and volumes fall simultaneously, it signals that downstream acceptance of current price levels is deteriorating rapidly.
Why Higher Quotes Failed to Generate Transactions
Industry data show that most polyester filament manufacturers did raise offer prices, but the magnitude of transaction-level increases varied widely. Some mills saw their hikes absorbed by the market; others faced a situation where quotes existed but deals did not. This divergence is itself a market signal: downstream weavers do not accept a blanket upward revision and prefer to buy on demand rather than chase prices upward.
The breakdown of sales ratios across sampled enterprises reinforces this view. The highest ratio reached 310%, the lowest was zero, and most clustered between 10% and 30%. Such a wide gap indicates that orders are concentrating among a few mills with pricing advantages or differentiated products, while a large volume of homogeneous capacity struggles to ship. For buyers, this means negotiating leverage may emerge with suppliers whose sales ratios remain persistently low.
On the cost side, raw material prices for polyester filament have not fluctuated dramatically. The upward quote adjustments are driven more by mills' desire to restore margins. But with weak orders at the weaving stage, this cost pass-through is difficult to absorb smoothly. Profit distribution along the chain is tilting from upstream to downstream—whoever cannot withstand inventory pressure will be the first to concede on price.
Loom Utilization Is the Real Barometer
The sales ratio of polyester filament is never an isolated indicator. Behind it lie loom utilization rates, order backlogs, and finished goods inventories at weaving mills. The recent decline in loom utilization runs deeper than the phrase "off-season production cuts" suggests. Weaving enterprises in several industrial belts report noticeably fewer new order inquiries and longer repeat-order cycles from regular clients, leaving factories reluctant to run at full capacity.
In chemical fiber weaving clusters such as Keqiao and Shengze, the pressure comes from both domestic and export markets. Domestically, apparel brands and home textile companies are slow in their autumn stocking, adopting conservative procurement plans. On the export side, some orders are squeezed by exchange rate fluctuations and shipping costs, reducing traders' willingness to place orders. Once weaving mills cut production, their filament procurement shifts from weekly restocking to hand-to-mouth buying, naturally weighing on sales ratios.
This transmission has a lag. Loom slowdowns typically precede filament sales ratio declines by one to two weeks. Therefore, the current 39.1% may reflect the cumulative effect of an earlier round of weaving production cuts. If loom utilization cannot recover in the short term, a trend reversal in filament sales data is unlikely.
Price Expectations and Inventory Game
The coexistence of higher quotes and falling sales ratios essentially reflects divergent views along the supply chain. Upstream polyester plants, constrained by contract obligations and cash flow needs, tend to hold prices firm. Midstream traders, with varying inventory costs, may choose to sell at a discount. Downstream weavers, convinced that "prices will fall further if we wait," collectively stay on the sidelines. Under this three-way game, thin trading volume is inevitable.
For factories, the most pressing issue is not price but inventory turnover. A sales ratio persistently below 50% means physical inventories are accumulating passively. If this persists beyond two weeks, some cash-strapped enterprises may be forced to cut prices, triggering localized price wars. For buyers, this presents both risk and opportunity—the risk of catching a falling knife, and the opportunity to negotiate with suppliers under inventory pressure who offer stable quality.
Exporters need to watch two variables: exchange rates and shipping costs. Export quotes for polyester filament and downstream fabrics are typically denominated in US dollars, so RMB fluctuations directly affect margins. Meanwhile, freight rate adjustments on certain routes can alter clients' ordering节奏, which in turn affects production scheduling at domestic weaving mills.
