The price divergence in the textile raw material market during the second week of July 2026 is more than a short-term fluctuation—it signals a redistribution of profits along the supply chain. PTA surged 2.25% week-on-week, closing at 5,910.50 yuan per ton, with a year-on-year increase of 21.80%, making it the strongest performer. However, downstream polyester filament yarns failed to follow: FDY fell 1.68%, DTY dropped 1.28%, and POY declined 0.77%. This pattern of upstream gains and downstream losses has been rare in the past year.
Profit Concentration Upstream
PTA's strength is not isolated. Looking at year-on-year data, PTA, spandex, polyester POY, and cotton all saw increases exceeding 15%, while downstream cotton yarn, rayon yarn, and polyester yarn posted gains of only 3% to 9%. Raw silk even fell 10.07%. This indicates that cost increases over the past year have not been effectively passed down to the yarn segment.
For weaving mills and fabric buyers, this creates a dangerous scissors effect. Upstream PTA and polyester staple fiber (up 0.95% weekly) continue to push costs higher, but downstream filament and yarn prices are under pressure from weak end-demand. Acrylonitrile plunged 4.20% to 9,133.33 yuan per ton, further confirming weak demand for chemical textile raw materials—acrylic and its blends may be seeing order contraction.
Cotton vs. Chemical Fibers: Two Different Trajectories
The cotton segment performed relatively moderately. Cotton yarn 32S rose 0.61%, 21S gained 0.28%, while cotton lint fell 0.92%. The slight rise in cotton yarn prices alongside the mild decline in cotton lint has improved the immediate profit margin for spinning mills. But sustainability is questionable: downstream grey fabric and finished fabric markets lack signals for large-scale restocking, suggesting the price increase is cost-pushed rather than demand-driven.
Divergence within the chemical fiber sector was more pronounced. Polyester staple fiber rose 0.95%, but filament yarns all fell, with FDY and DTY dropping over 1%. This pattern—strong staple, weak filament—reflects end-use demand shifting toward staple-based products (nonwovens, fillings) while conventional filament fabrics like polyester taffeta face rising inventory pressure. Viscose staple fiber and spandex prices were flat, indicating a stalemate in the rayon and elastic fiber markets.
Implications for Procurement and Inventory Strategy
The current price structure sends several key signals. First, PTA's strength is unlikely to reverse in the near term; profits in the polyester chain will increasingly flow to the PTA segment, weakening the bargaining power of downstream polyester plants. Second, falling polyester filament prices open a procurement window for weaving mills, but only if they can distinguish between a temporary correction and a structural downtrend. Third, the sharp drop in acrylonitrile presents a potential opportunity for buyers of acrylic and blended products to lock in low prices, but they must be cautious about the impact of raw material volatility on order stability.
From a macro perspective, the structural divergence in textile raw material prices is essentially a collision between capacity expansion since 2025 and slowing demand. PTA capacity is relatively concentrated, giving suppliers stronger pricing power, while polyester filament capacity is more fragmented, leading to fiercer price competition in a weak demand environment. This pattern is likely to persist until the end of Q3, barring large-scale production cuts or an export order surge.
