A rapid rise in crude oil prices is triggering a chain reaction in the textile chemical fiber industry. On July 8, the average sales-to-production ratio of polyester filament yarn sample enterprises surged to 103.6%, a sharp increase of 60.7 percentage points from the previous trading day. This data directly reflects the immediate impact of short-term upstream raw material cost fluctuations on downstream purchasing sentiment.
Cost-Driven Pulse Procurement
Crude oil, as the most upstream segment of the polyester chain, transmits price changes quickly through the PX-PTA-MEG chain to polyester filament yarn. The July 8 data shows that synchronized increases in crude oil and polyester feedstock prices directly activated downstream weaving enterprises that had been on the sidelines. A 103.6% sales-to-production ratio means that daily shipments exceeded production, with some factories beginning to draw down inventory. However, sample enterprise data reveals extreme unevenness: the highest ratio reached 300%, while the lowest was only 10%. This wide divergence indicates that the price rally has not formed a broad consensus but rather appears as sporadic outbreaks.
Critical Inventory Cycle Point
The backdrop for this sudden sales surge is a prolonged inventory buildup in the polyester filament yarn sector. Downstream weaving enterprises had generally maintained low raw material inventories, waiting for clearer cost bottom signals. The sudden crude oil price rally broke this stalemate. For buyers, the fear of sustained raw material cost increases driving up total costs is the core psychological factor behind the concentrated restocking. However, a single-day pulse improvement does not mean a fundamental turnaround in industry fundamentals. Whether the sales ratio can remain high depends on actual downstream order fulfillment, not purely speculative stockpiling.
Regional Industry Belt Reactions
From a regional perspective, major polyester filament yarn producing and selling areas such as Xiaoshan and Shaoxing in Zhejiang, and Shengze in Jiangsu, were most sensitive to this price fluctuation. Weaving enterprises in these regions are mostly small and medium-sized, with low tolerance for raw material price volatility and easily swayed by short-term market sentiment. When upstream price signals became clear, enterprises prioritized rapid restocking to lock in costs rather than waiting for prices to fall. Notably, there are no signs of synchronized increases in end-brand apparel orders. This means that if polyester feedstock cost pressure cannot be effectively passed down to the garment stage, the current high sales ratio may simply represent inventory transfer from polyester factories to weavers, not actual final consumption.
Sustainability Assessment
The 103.6% sales ratio is undoubtedly positive, but its sustainability warrants caution. Historical experience shows that single-day sales bursts driven by cost factors are typically short-lived, reverting to supply-demand fundamentals. Currently, global crude oil supply remains uncertain, with OPEC+ production policies and geopolitical risks as core variables affecting polyester feedstock costs. If crude oil prices remain high and volatile, polyester filament yarn prices may find support, and the sales ratio may stay in a reasonable 80%-100% range. Conversely, if crude oil prices peak and fall, downstream restocking enthusiasm will cool rapidly, and the sales ratio could slump back to below 50%.
