Nylon Leads, PTA Under Pressure: The Industrial Logic Behind Textile Raw Material Price Divergence on July 16

On July 16, 2026, the textile raw material market presented a notable price scissors: nylon series products collectively advanced, while PTA, a key upstream feedstock in the chemical fiber chain, recorded a 0.51% decline. The overall average daily change in the textile sector was only 0.04%, but the internal structural divergence was far more dramatic than the headline figure suggests.

The Strong Logic of the Nylon Chain

Nylon POY led the sector with a 0.74% daily gain, reaching 13,600 yuan/ton, with a year-on-year increase of 11.48%. Nylon DTY rose 0.25% to 15,800 yuan/ton. This is not an isolated fluctuation—year-on-year, nylon POY and DTY have risen 11.48% and 9.27% respectively, significantly outperforming polyester staple fiber (+12.26%) and cotton yarn (around +6.7%).

The rally stems from a tightening supply-demand balance in the nylon chain. Tight caprolactam supply upstream, combined with resilient demand from downstream sectors such as outdoor sportswear and yoga apparel, gives nylon mills strong pricing power. For buyers, this means the cost center for nylon fabrics is systematically shifting upward, and the window for locking in prices for H2 orders is narrowing.

PTA's Counter-Trend Warning

In stark contrast to nylon's strength, PTA fell 0.51% to 6,012.25 yuan/ton. Although its year-on-year increase remains high at 26.96%, the short-term retreat warrants attention. PTA is the 'engine' of the polyester chain; its weakness typically signals either softening PX cost support or a marginal decline in downstream polyester operating rates.

According to industry data, PTA social inventories have accumulated recently, with supply increasing after maintenance restarts. Meanwhile, polyester filament yarn (POY/DTY/FDY) prices have been flat for weeks, and downstream weaving mills show weak restocking intent, suppressing PTA prices. This pattern of 'weak upstream, stable midstream, wait-and-see downstream' suggests that profits are concentrating at the PX stage, while PTA's bargaining power is being eroded.

The 'Silent' Game Between Cotton and Synthetics

Cotton-related products were subdued: cotton lint edged up 0.05% to 17,733.67 yuan/ton, while cotton yarn 21S and 32S were flat. Year-on-year, cotton lint has risen 15.97%, but cotton yarn is only up about 6%—the failure to fully pass on raw material costs means spinning margins have been squeezed.

Polyester staple fiber rose 0.12%, while viscose staple fiber and spandex were unchanged. Spandex's year-on-year gain of 22.34% is high, but its price has stalled recently, suggesting demand for elastic fabrics may have entered a plateau. Overall, the chemical fiber sector is shifting from broad-based gains to divergence: nylon is strengthening due to a supply-demand gap, while polyester and viscose are caught between cost and demand pressures.

Practical Recommendations

For Buyers - Lock in major nylon fabric contracts for H2 before the end of July, to avoid further cost increases from tight caprolactam supply. - The temporary PTA dip may loosen polyester filament prices; consider slowing procurement of conventional items like taffeta and pongee to wait for a better entry point. - Cotton yarn spot prices are stagnant, but the supply-demand balance remains tight before the new cotton crop arrives; avoid being bearish and maintain safety stock.

For Foreign Trade Companies - Raise export quotations for nylon fabrics promptly, especially for European and American sportswear clients, explaining the raw material cost pass-through. - For polyester orders, try to negotiate floating price clauses linked to PTA futures to reduce unilateral lock-in risk. - Monitor PTA plant dynamics and PX price trends; if PTA falls below 5,900 yuan/ton, it could be a signal of a cyclical bottom for polyester fabric procurement.
