In the third week of July 2026, the textile bulk commodity price index posted a modest 0.54% weekly gain, but the structural divergence beneath the surface is far more telling than this gentle average. Acrylonitrile led all gainers with a 5.11% surge, while cotton yarn prices bucked the trend and fell, creating a clear picture of strong upstream chemical fibers versus weak downstream cotton spinning. This divergence is reshaping bargaining power and profit distribution across the textile chain.
Chemical Fiber Sector: Acrylonitrile Stands Out, PTA and Polyester Follow
Acrylonitrile was the star performer of the week, with prices jumping from 9,133 yuan/ton to 9,600 yuan/ton, a year-on-year increase of 22.29%. This spike is not an isolated event but the combined result of upstream raw material cost pass-through and temporary supply tightness. As a key input for acrylic fibers and ABS resins, the price rise will directly inflate costs for downstream textile products, and buyers should watch for margin compression on Q3 orders.
PTA and polyester staple fiber rose 1.48% and 1.30% respectively, with year-on-year gains of 25.68% and 12.73%. PTA, the hub of the polyester chain, drives the strength in polyester filament yarn (POY up 0.69%, DTY up 0.75%) and staple fiber. The core driver is sustained high crude oil prices and tight PX supply, a trend unlikely to reverse soon. For fabric mills relying on polyester, raw material cost pressure is building.
Notably, spandex prices held steady at 29,667 yuan/ton but are up 22.34% year-on-year, indicating a high-level plateau. Market acceptance of such high prices is limited, and downstream weavers are beginning to seek alternatives or reduce usage. Viscose staple fiber and rayon yarn also stayed flat, signaling a wait-and-see period after earlier price hikes.
Cotton Spinning Sector: Cotton Yarn Under Pressure, Diverging from Cotton
In stark contrast to the chemical fiber rally, the cotton spinning sector was weak. Cotton yarn 32S and 21S fell 0.60% and 0.57% respectively, while raw cotton prices inched up 0.13%. This divergence—cotton up, yarn down—typically indicates insufficient downstream demand for grey fabrics and garments, forcing mills to cut yarn prices to destock.
Year-on-year, cotton yarn 21S is up 6.71% and 32S up 6.23%, but raw cotton has surged 15.31%. The gap between raw material cost and yarn price has severely compressed mill margins. If terminal orders remain sluggish through the traditional August lull, cotton mills may face tough choices: reduce output or shift to polyester blends.
Raw silk fell 0.14%, with a year-on-year decline of 10.34%—the only monitored commodity in negative territory on an annual basis. This reflects persistent weakness in silk end-use consumption, especially from luxury markets in Europe and the US. For the silk cocoon chain, export prospects for the second half remain challenging.
Chain Transmission Logic: Strong Upstream, Weak Downstream, Inventory Strategy Needs Adjustment
Looking at the overall structure, the biggest gainers (acrylonitrile, PTA, polyester staple fiber) are all upstream or intermediate inputs, while the losers (cotton yarn, raw silk) are closer to final consumption. This pattern suggests a cost-push inflation that is meeting resistance from weak demand.
For weaving and garment companies, raw material procurement strategies need to be more nimble. The sustained rise in chemical fiber prices may prompt early price locking for Q3 orders to avoid further cost escalation. For cotton yarn purchases, a low-inventory, fast-turnover approach is recommended, waiting for clearer demand signals before restocking.
Regional Industrial Cluster Reactions: Shengze, Keqiao, Nantong
Shengze, a hub for polyester filament and fabrics, will see local grey fabric costs rise directly due to the POY and DTY increases. Keqiao, focused on chemical fiber fabrics and home textiles, will feel the impact of PTA and polyester staple fiber price swings on procurement. Nantong, a home textile center, should watch the price spread between cotton yarn and polyester staple fiber; if cotton yarn continues to weaken, pure cotton home textile products may see a temporary competitiveness boost.
