At the close of the morning session on August 31, the domestic futures market showed clear sector divergence: polyester chain products strengthened collectively, with bottle chip futures surging 4.63% to 7,498 points, staple fiber up 3.19% to 7,708 points, and PTA up 3.04% to 5,766 points. In contrast, cotton-related products weakened, with cotton yarn down 1.04% to 22,900 points and cotton down 0.67% to 17,085 points. This divergence reflects two distinct cost and supply-demand logics in the textile raw material sector.
Market Background
The polyester chain's strength is not an isolated phenomenon. Bottle chips, staple fiber, and PTA all rose simultaneously, with gains tapering from upstream to downstream—PTA up 3.04%, staple fiber up 3.19%, and bottle chips up 4.63%. This pattern indicates cost-push as the primary driver, while larger gains in downstream products suggest additional supply-side support. Staple fiber and bottle chips, as direct downstream products of polyester, outperforming PTA implies expanding processing margins and strong price support from factories.
Cotton's weakness contrasts sharply with the polyester chain. Cotton futures at 17,085 points have fallen notably from earlier highs, and while cotton yarn's decline is smaller, the 22,900-point level is near the cost line for many spinning mills. The cotton textile chain's weakness stems from supply pressure from the upcoming new cotton harvest and insufficient recovery in downstream fabric and apparel orders.
From a capital flow perspective, the pattern of more gainers than losers suggests a generally risk-on sentiment, but funds clearly favor chemical products supported by crude oil prices over agricultural products dependent on weather and planting area. This choice reflects dual judgments: tight global crude supply and abundant cotton harvest expectations.
Industry Impact
The polyester chain's rise means higher raw material costs for downstream weaving enterprises. For example, staple fiber at 7,708 points is over 5% higher than last month, directly compressing profit margins for midstream yarn producers. For factories focusing on polyester yarn or polyester-cotton blends, failing to pass on costs could shrink gross margins by 2-3 percentage points. Conversely, large chemical fiber companies with integrated polyester capacity can hedge via internal supply chain offsets.
Cotton textile enterprises face a more delicate situation. Lower cotton prices should benefit spinning costs, but cotton yarn falling simultaneously with a larger decline indicates demand weakness outweighing cost benefits. In textile hubs like Weiqiao in Shandong and Xinye in Henan, operating rates hover around 70%, while finished goods inventories are rising, showing downstream purchases are mostly for immediate needs with low restocking appetite.
Notably, the price gap between polyester and cotton is widening. The spread between staple fiber and cotton has narrowed from around -2,000 yuan/ton at the start of the year to -9,377 yuan/ton (based on futures), meaning polyester's substitution advantage over cotton is strengthening. For apparel brands and home textile companies, cost pressures may push polyester content higher in blends, exerting long-term pressure on cotton demand.
Practical Recommendations
Given the divergence in raw material trends, enterprises at different stages should adopt differentiated strategies. Buyers need to closely monitor crude oil dynamics, as the polyester chain's rise is highly dependent on cost support; any oil correction could quickly erase gains in staple fiber and PTA. Cotton textile enterprises should use futures tools for hedging to lock in future raw material costs.
