The night session closing data on July 10 sent a signal worth noting: cotton yarn and cotton main contracts rose 0.45% and 0.40% respectively, while PTA fell 0.75%, bottle-grade chips dropped 0.32%, and staple fiber barely held flat. This pattern of cotton strength and chemical fiber weakness is not a random daily fluctuation but a direct reflection of the fundamental differences between the two industrial chains.
Cotton Chain: Cost Floor and Low Inventory Support Short-Term Resilience
Cotton yarn 2609 settled at 22,510 points, and cotton 2609 at 16,120 points. From an industrial perspective, this slight uptick is the combined result of weather disruptions in Xinjiang cotton regions and ginners' reluctance to sell. Domestic cotton commercial inventories have fallen to near three-year lows for this period, and with months before the new crop arrives, supply-side contraction expectations provide a hard floor for prices.
For downstream weaving mills, the modest rise in cotton yarn means higher immediate procurement costs. However, cotton yarn's gain did not significantly outpace cotton, leaving spinning margins still narrow. This implies that unless grey fabric orders pick up simultaneously, weavers' willingness to absorb higher-priced cotton yarn will quickly fade, casting doubt on the rally's sustainability.
Polyester Chain: PTA Decline Reflects Loose Feedstock and Weak Demand
PTA 2609 fell 0.75% to 5,568 points, the biggest decliner in the night session. Behind this is the loosening of PX cost support and inventory pressure from high PTA operating rates. Bottle-grade chips 2609 dropped 0.32%, and staple fiber 2609 barely held flat at 7,038 points, with the overall polyester chain performing weakly.
From an industrial logic perspective, PTA's weakness directly transmits downstream to polyester filament and staple fiber. Current weaving operating rates have seen seasonal declines, grey fabric inventories are slow to clear, and polyester plants' sales rates remain persistently low. Although staple fiber managed to hold flat, the 7,038-point level is still in the low range for the year, lacking upward momentum.
Notably, the divergence between PTA and cotton yarn means that pure cotton products and blended/polyester products are following different pricing logics. Procurement teams must assess risks for each chain separately when formulating raw material mix strategies.
Industrial Impact: Three Judgments from the Divergence
First, the cotton chain's short-term resilience does not equal a trend reversal. The 16,000-point area for cotton faces hedge pressure, and downstream fabric mills are still buying only for immediate needs, with little speculative stockpiling appetite. Second, the polyester chain's weakness is likely to persist. PTA processing margins have compressed to low levels, but without significant demand improvement, prices may continue to drift toward cost. Third, staple fiber's flat position is the most fragile. If PTA declines further, staple fiber will lose support and face catch-down risk.
For textile enterprises, this market pattern demands more refined raw material inventory management. Cotton mills can moderately lock in forward supplies on dips but should avoid chasing rallies. Chemical fiber mills should accelerate finished product destocking to avoid accumulating inventory risk during a price downtrend.
