Nylon Chain Deep Correction, PTA Unexpectedly Strong: Textile Raw Material Market Divergence Intensifies

In the first week of June 2026, the textile bulk commodity market showed a rare polarization. PTA led the sector with a 3.87% weekly gain and a staggering 34.36% year-on-year increase. Meanwhile, the nylon chain suffered a broad sell-off, with DTY, POY, and FDY falling 3.61%, 3.45%, and 2.94%, respectively. The sector average weekly change was -0.48%, but the structural divergence is more telling than the headline number.

Divergence in Cost Transmission

PTA's strength is not isolated. Firm upstream PX prices, supported by high crude oil, combined with production curtailments at several plants, tightened supply and pushed spot PTA prices higher. The 34.36% year-on-year gain far outpaces other products, indicating a cost-push rather than demand-pull rally. The mere 0.21% rise in polyester staple fiber confirms this—downstream weaving mills are reluctant to absorb higher raw material costs, preventing PTA gains from passing through.

The synchronized decline in the nylon chain points to a different logic. Nylon DTY, POY, and FDY all fell around 3%, suggesting a sector-wide supply-demand imbalance rather than single-specification volatility. Easing caprolactam prices and weak downstream nylon fabric orders jointly pressured nylon yarn prices. Notably, nylon products had seen significant gains earlier, so the current correction also reflects profit-taking at elevated levels.

Cotton and Viscose: A Stalemate

Cotton yarn 21S, 32S, viscose staple fiber, and rayon yarn all posted flat prices. On the surface, this looks like stability, but in reality, it signals a market standoff. Cotton rose 0.76%, yet cotton yarn prices did not move, indicating that spinners are absorbing margin compression rather than raising prices. Viscose staple fiber also remained flat, with weak downstream rayon yarn demand keeping mills on a hand-to-mouth procurement strategy. This 'raw material up, yarn flat' dynamic continues to pressure cash flows for spinners.

Spandex prices were unchanged. After significant volatility last year, the current plateau suggests supply and demand are in relative balance, but the 21.77% year-on-year gain remains elevated, challenging cost control for downstream stretch fabric manufacturers.

Silk and Acrylonitrile: Weak Signals

Raw silk fell 0.67% this week, and its 7.10% year-on-year decline is the only negative reading in the sector. The silk market remains depressed, dragged by weak luxury apparel consumption and no clear improvement in export orders. Acrylonitrile dropped 1.97%; despite a 21.88% year-on-year gain, this month-on-month reversal may signal the end of its prior uptrend, a bearish sign for acrylic and carbon fiber feedstock.

Procurement Strategy in a Divergent Cycle

The current textile raw material market shows three characteristics: cost-driven products (PTA) diverge from demand-driven ones (nylon); the cotton spinning chain faces margin compression; and flat products await directional cues. For downstream buyers, distinguishing 'true inflation' from 'false inflation' is critical. PTA's rally is unsustainable if it cannot pass through to downstream fabrics. Nylon's decline, if a cyclical correction, may offer a buying opportunity.

For Procurement Managers - Monitor the spread between PTA and polyester filament. If polyester fails to follow PTA higher, consider reducing PTA purchases and wait for a pullback. - Nylon products have already corrected significantly. If downstream orders show signs of recovery, consider phased buying to lock in low prices, but avoid large one-time positions. - For cotton yarn and viscose, stick to hand-to-mouth procurement and avoid building inventory until raw material trends become clearer.

For Export Companies - When quoting export orders for PTA-related products, build in a margin for raw material cost increases to protect profits. - For nylon products, negotiate price adjustment clauses with clients and leverage current lower prices to offer more competitive export quotes. - For raw silk exports, shorten the validity period of your quotes to hedge against further price declines and dual risks from forex and inventory.
