On July 10, 2026, the average sales-to-output ratio of polyester filament yarn sample enterprises plummeted to 35.5%, down nearly 5 percentage points from the previous day. This figure means that for every 100 tons of polyester filament produced, fewer than 36 tons were actually purchased by downstream buyers. At a seasonal inflection point in the textile industry, such a sales ratio sends a strong signal of market cooling.
The Signal Behind the Data
Looking at the publicly available sales data distribution, the ratio across sample enterprises varied widely, ranging from a low of 0% to a high of only 70%. More than half of the enterprises recorded ratios between 20% and 35%, indicating a broad market slowdown. This contrasts sharply with the previous round of concentrated downstream replenishment, revealing that when end-demand cannot sustain inventory absorption, the midstream polyester filament sector bears the immediate brunt.
From an industry chain transmission perspective, the sales-to-output ratio is a core leading indicator of chemical fiber market health. A level below 40% typically signals extremely weak purchasing willingness among weavers, placing the market firmly in a buyer-dominated pattern. Historical data suggests that if this trend persists for more than a week, polyester filament factories will be forced to cut prices or reduce production to balance supply and demand, triggering adjustments in upstream PTA and MEG prices.
How Downstream Caution Affects Industrial Clusters
Major chemical fiber industrial clusters in Xiaoshan, Shaoxing, and Shengze are all feeling the pinch of weaker downstream orders. Weaving enterprises report that the slower ordering pace from end-apparel brands has led to their own finished goods inventory build-up. In this context, their procurement strategy for polyester filament has shifted from 'buy-as-needed' to 'buy-only-when-urgent,' with some even halting new purchases to digest existing stocks.
For upstream polyester plants, the current drop in sales ratio is not an isolated event. Since early July, polyester filament prices have shown signs of weakening, with discounts widening on certain specifications. If the ratio remains low, factories will face dual pressures of inventory accumulation and cash flow constraints, potentially leading to more aggressive promotions or production cuts in mid-to-late July.
Dual Tests from Exports and Domestic Demand
Externally, exports of polyester filament and downstream textile products face uncertainties. Overseas market inventories have not been fully digested, and new order growth is limited. Domestically, the textile industry is transitioning from the traditional off-season to autumn stocking, but downstream hesitation suggests clear expectations of further price declines.
This negative cycle of 'the more prices fall, the more buyers wait' has structural impacts on industrial clusters. Small and medium-sized weaving enterprises, with fragile cash flows, are particularly sensitive to raw material price fluctuations. Once price decline expectations solidify, their procurement decisions will be further delayed, exacerbating upstream inventory pressures.
