On the last trading day of June 2026, bulk commodity prices in the textile sector showed a clear divergence. PTA rose 0.90% and acrylonitrile gained 0.50%, but downstream polyester products—polyester FDY, staple fiber, POY, and DTY—all declined, with losses ranging from 0.13% to 0.68%. This 'hot upstream, cold downstream' pattern is not random volatility but a concentrated reflection of supply-demand contradictions across the industrial chain.
Cost Push vs. Demand Pull
PTA’s rise has clear cost support. International crude oil prices remained high in late June, directly pushing up PX (paraxylene) costs and then PTA. Year-on-year, PTA is up 13.78%, among the highest of all monitored products. Acrylonitrile’s 26.14% year-on-year gain is tied to strong demand from ABS resin and carbon fiber sectors.
However, this cost push did not pass through to polyester finished products. Polyester FDY and staple fiber prices fell, with year-on-year gains of only 14.64% and 10.15%, both below PTA’s. This directly indicates weak purchasing willingness from downstream weaving and apparel markets. Mills are buying on an as-needed basis, causing polyester plants to accumulate inventory and cut prices.
Profit Reallocation Along the Chain
Price data clearly shows profits are concentrating upstream. PTA producers can raise prices on cost grounds, but polyester filament and staple fiber makers face a 'flour more expensive than bread' dilemma. Polyester POY is up 11.39% year-on-year, DTY 8.95%, both below PTA’s gain, meaning processing margins in the polyester segment are being squeezed.
This profit structure shift demands new procurement strategies. For garment and home textile companies relying on polyester fabrics, volatile raw material prices mean greater cost control challenges. Meanwhile, viscose staple fiber, rayon yarn, and cotton yarn prices were flat, indicating a relatively stable but momentum-free non-polyester market.
Raw Silk’s Divergent Signal
Raw silk stands out among all monitored products. Its price fell 9.89% year-on-year, the only double-digit decline. This directly reflects weak downstream silk consumption. In recent years, silk fabrics have lost market share to fast fashion and functional textiles. Meanwhile, silkworm cocoon supply remains stable, leaving raw silk without price support.
This weak performance pressures sericulture regions like Guangxi and Zhejiang. Reeling mills face inventory devaluation risks, while silk fabric processors can use low-cost raw materials to optimize costs. But long-term, without a recovery in end consumption, low prices alone won’t spark a demand rebound.
