The polyester filament yarn market is experiencing a notable slowdown in transactions. On July 21, the average sales-to-production ratio among sampled enterprises fell to 38.2%, down 2.4 percentage points from the previous trading day. This means that for every 100 tons of filament yarn produced that day, less than 39 tons were purchased by downstream buyers, signaling mounting inventory pressure on mills.
Behind the Sales Data: Market Sentiment
Examining the sales ratios of 23 sampled enterprises reveals a classic long-tail distribution: most companies reported ratios between 20% and 40%, with the lowest two recording zero sales. Only one enterprise achieved 80%, while all others remained below 50%. This pattern indicates that purchasing sentiment across downstream weaving and texturing sectors is broadly weak, and the decline is systemic rather than localized.
Pricing strategies among filament yarn producers have also diverged. Some mills attempted modest price hikes to test market response, while others opted for discounts to move inventory, resulting in a mixed pricing landscape. However, actual transaction volumes remained low regardless of price direction. This suggests that the core issue lies not in price levels but in the absence of end-use orders—weaving mills, burdened by their own high finished-goods inventories, have little incentive to restock raw materials.
Cost Support vs. Demand Suppression
On the upstream side, PTA and MEG prices have been oscillating within a narrow range recently, offering no clear directional signal from the cost side. Although polyester mills' cash flows have improved somewhat, the margin gap is not yet wide enough to trigger concentrated downstream restocking. Meanwhile, social inventories of polyester filament yarn, after a period of destocking earlier this year, have seen the pace of reduction slow markedly in the past two weeks, with some specifications even beginning to accumulate again.
Downstream, loom operating rates in Jiangsu and Zhejiang provinces have slipped by 3-5 percentage points from their late-June peak, and gray fabric inventory turnover days have extended beyond 28 days. Orders for home textile and apparel fabrics are characterized by "small lots, few large orders," as brands and traders generally adopt a "sell-first, purchase-later" approach and are reluctant to build safety stocks. This cautious sentiment is propagating upstream, weighing on polyester filament yarn sales rates.
Inventory Cycle and Price Expectations
Current polyester filament yarn inventory levels are in the upper-middle range of the past year. If the 38.2% sales ratio persists, the industry's monthly inventory buildup could exceed 150,000 tons, putting substantial pressure on mill cash flows. Historical patterns show that when the sales ratio stays below 40% for two consecutive weeks, polyester mills are likely to activate a "price cuts—production cuts—maintenance shutdowns" response chain.
Notably, late July to early August typically marks the tail end of the traditional textile off-season, when some weaving mills begin to stockpile raw materials for autumn/winter orders. However, this year's restocking window may be delayed—uncertainty in brand replenishment schedules and the impact of RMB exchange rate fluctuations on export order margins are making downstream buyers more hesitant. If polyester filament yarn prices fail to stimulate effective restocking by early August, the supply-demand balance for the mid-to-late third quarter will face greater challenges.
