On September 4, 2026, the textile bulk commodity market presented a rare divergence: nylon chain products led gains while upstream raw materials like acrylonitrile and PTA declined. According to data from Shengyi Society, nylon POY rose 1.71% to 14,875 yuan/ton, with nylon FDY and DTY up 1.62% and 1.55% respectively. This combination of downstream price hikes and upstream declines often signals a redistribution of profits along the supply chain, offering direct reference for buyers and mills in short-term strategy.
Market Snapshot
The textile sector posted an average daily change of 0.32%, but internal movements were mixed. Six products gained, led by nylon chains, with viscose staple fiber (+0.97%), viscose yarn (+0.96%), and raw silk (+0.85%) also rising. Four products fell: acrylonitrile dropped 0.87%, PTA 0.61%, cotton 0.42%, and polyester staple fiber 0.24%. Cotton yarn, polyester yarn, spandex, and polyester filaments remained flat.
Year-on-year data shows most products still sit at elevated levels. PTA surged 38.43%, acrylonitrile 41.37%, polyester staple fiber 26.75%, and nylon POY 23.44%. Raw silk was the only decline, down 8.67%, indicating loose supply in the cocoon segment. The coexistence of broad annual gains with daily declines suggests a shift from one-way rally to high-level volatility, raising price sensitivity.
Industrial Implications
The collective rise in nylon chain is not isolated. Nylon POY, FDY, and DTY moving up together reflects recovering demand—downstream weaving and warp knitting mills are restocking. Meanwhile, stable caprolactam prices allow nylon producers to pass costs downstream and expand processing margins. In contrast, acrylonitrile declines may relate to new capacity releases, while PTA weakens due to crude oil fluctuations and polyester operating rates.
For buyers, this means near-term nylon fabric costs rise, but upstream declines offer future bargaining room. For mills, improved nylon margins may boost operating rates, yet they must guard against inventory devaluation from sustained raw material weakness. Polyester staple fiber dipped while filaments held steady, indicating cautious sentiment across the polyester chain with no full-blown order recovery.
Raw silk's 8.67% year-on-year drop deserves attention. As a high-end fabric input, its weakness may reflect soft export demand or substitution by synthetic fibers. For home textile and apparel firms, this low-price window could be a buying opportunity, but should be weighed against end-consumption data. Overall, the day's board shows a structural pattern of "strong chemical fibers, weak natural fibers," consistent with the global shift of textile capacity toward synthetics.
