On July 10, trading in the polyester filament yarn market turned abruptly cold. Industry public data shows the average sales-to-output ratio among sample enterprises was only 35.5%, a sharp decline of 4.9 percentage points from the previous trading day. This means for every 100 tons of polyester filament yarn produced that day, fewer than 36 tons were purchased by downstream buyers, with the remainder directly converted into inventory.
Downstream Purchasing Rhythm Shifts: Collective Retreat After Concentrated Restocking
Looking at specific sales data, the ratios for sample enterprises on that day were highly dispersed, ranging from 0% to 70%, but most fell in the low range of 20%-35%. One enterprise recorded zero sales, indicating no new orders were secured that day. Even the single high point of 70% was far from the breakeven line of 100%. This 'fire and ice' pattern suggests downstream users are not universally short of funds or shutting down; rather, purchasing willingness has become highly polarized—with the majority choosing to wait and see.
The key change lies in purchasing rhythm. After the previous round of concentrated restocking, downstream weaving mills quickly exited the market. This implies that earlier purchases were more a reactive response to price hikes or supply tightness, rather than based on sustained demand from real orders. Once restocking was completed, the market immediately fell into a state of neglect.
Upstream Pressure: Inventory Accumulation and Price Negotiation
A sales-to-output ratio persistently below 100% directly leads to accumulation of finished goods inventory at polyester filament yarn plants. For polyester factories, a ratio of 35.5% means over 60% of daily output must be stored as inventory. If this continues, warehousing costs and capital occupation costs will rise in tandem. In extreme cases, this may force factories to cut prices to boost cash flow.
However, price cuts are not a panacea. The core issue for downstream weaving mills is terminal demand—whether actual demand from end-consumer sectors like apparel and home textiles is strong enough. Without a clear rebound in final orders, downstream enterprises have no incentive to stockpile heavily even if polyester filament yarn prices drop. This creates a classic 'buyer's market': upstream eager to destock, downstream holding cash on the sidelines.
Industry Transmission: From Chemical Fiber to Weaving to End-Use
The sharp drop in polyester filament yarn sales is essentially a signal of obstructed demand transmission along the supply chain. As a core intermediate in the chemical fiber industry, the price and volume of polyester filament yarn directly impact upstream markets for PTA and MEG, and determine the cost structure of downstream grey fabrics and finished textiles.
From a regional industrial cluster perspective, major production and sales areas for polyester filament yarn—such as Xiaoshan and Shaoxing in Zhejiang, and Shengze in Jiangsu—may soon feel significant inventory pressure. If local weaving mills cannot maintain high operating rates, demand for polyester filament yarn will weaken further. Once polyester factories begin destocking via price cuts, the PTA and MEG markets will also be affected, as raw material cost support becomes weaker.
Notably, this sales data release comes in mid-July, traditionally the transition period between low and peak seasons in the textile industry. In previous years, orders for autumn/winter fabrics should gradually ramp up around this time. However, this year's sales performance seems to suggest that terminal restocking intentions are not strong.
