August saw a rare broad-based rally in textile raw material prices: the sector averaged a 2.52% monthly gain, with 15 of 16 monitored products rising, led by PTA (+6.02%) and cotton (+5.63%). This is not a mere cost pulse but a typical signal that chemical fiber and cotton spinning chains are simultaneously strengthening while downstream digestion lags.
Market Background
According to China Customs data, PTA spot prices rose from RMB 5,945.75/ton to RMB 6,303.50/ton in August, a year-on-year surge of 28.87%; cotton climbed from RMB 17,437.67 to 18,419.33, up 20.17% YoY. In the chemical fiber chain, polyester DTY, nylon POY, and polyester staple fiber gained between 3% and 4.5%, while acrylonitrile jumped 44.12% YoY, becoming the most prominent cost-side variable.
Notably, cotton yarn gains were mild: 32S cotton yarn rose only 0.81% and 21S 0.29%, clearly lagging the raw material surge. This implies a time lag in cost pass-through for cotton spinners, squeezing profit margins from both ends. Meanwhile, raw silk fell 9.35% YoY, indicating the silk sector remains in its own bottoming phase, out of sync with chemical fibers and cotton.
Spandex was the only decliner, down 0.56% MoM, yet still up 21.65% YoY. This 'down monthly, up yearly' pattern suggests spandex has already priced in earlier gains and is now in a high-level correction, offering slight relief to elastic fabric buyers.
Industry Impact
The broad rally is cost-push driven, not a sign of comprehensive demand recovery. The strength of PTA and acrylonitrile is directly linked to firm international oil prices and tight upstream supply of PX and propylene, which will eventually transmit along the chain: PTA→polyester→grey fabric→finished fabric. For weaving mills heavily reliant on polyester filament, raw material procurement costs rose about 4-6% in August, and if final order prices fail to keep pace, margins will be visibly eroded.
Cotton spinning transmission is more sluggish. Cotton surged 5.63%, but cotton yarn barely moved, indicating spinners are proactively absorbing costs to maintain customer loyalty before the peak season. This 'raw material up, yarn stable' pattern short-term benefits downstream fabric mills' cost control, but in the long run, if spinners cannot pass on costs, they may cut production or delay purchases, eventually pressuring upstream cotton prices.
For exporters, the combined effect of RMB-denominated raw material inflation and volatile ocean freight is pushing up quotation pressure. Orders for polyester and nylon fabrics, particularly those without price locks, risk margin erosion. Exporters are advised to incorporate raw material price indices into their quotation models or negotiate floating pricing mechanisms with clients.
