Textile Commodities Show Divergence: PTA and Polyester Staple Lead Declines, Chemical Fiber and Cotton Yarn Still Up Over 7% YoY

On July 10, 2026, a noteworthy signal emerged in the textile commodity market: despite an average price drop of only 0.15%, three key raw materials—PTA, polyester staple fiber, and cotton—fell simultaneously, while acrylonitrile and spandex still showed year-on-year gains above 15%. This divergence indicates that different segments of the supply chain are undergoing distinct stress tests.

Event Background: Small Daily Drops but a Unified Direction

According to price monitoring data from the industry, three textile commodities declined on July 10: cotton (-0.98%), polyester staple fiber (-0.82%), and PTA (-0.79%). Although the absolute daily drops are modest, the simultaneous decline of these upstream and intermediate materials sends a directional signal that cannot be ignored.

Year-on-year, PTA is still up 21.80%, cotton up 16.48%, and polyester staple up 9.43%. This means the current correction is a technical adjustment after significant prior gains. For buyers, the key question is whether this correction will evolve into a trend reversal.

Notably, raw silk fell 10.07% YoY, the only negative among monitored items. This reflects overcapacity in the silk industry and competition from substitute fibers, highlighting a shifting competitive landscape between natural and synthetic fibers.

Industry Impact: Upstream Cost Easing, Midstream and Downstream Margins Under Pressure

The simultaneous decline of PTA and polyester staple directly impacts profit distribution in the polyester chain. PTA is the core raw material for polyester filament and staple; lower PTA prices theoretically reduce production costs for downstream polyester yarn, POY, DTY, and FDY. Yet, data shows that polyester yarn prices remained flat, and POY/DTY/FDY did not follow the decline. This suggests that downstream mills are absorbing the cost reduction rather than passing it to end users, balancing inventory costs with market expectations.

Cotton's decline directly benefits cotton spinning mills. Cotton yarn 21S and 32S prices held steady, up 7.81% and 7.22% YoY respectively. Falling cotton prices with stable yarn prices mean expanding gross margins for spinners. For industrial clusters like Shengze and Nantong, this could be a critical window for Q3 profit recovery. However, buyers should note that cotton prices are seasonal, with a new round of adjustment expected around the August new crop arrival.

In the chemical fiber sector, acrylonitrile and spandex posted YoY gains of 15.61% and 21.09%, becoming the "high ground" in the current price landscape. Acrylonitrile is a raw material for acrylic and ABS resin; its high price will squeeze margins for downstream acrylic yarn and blended products. Spandex, driven by demand for sportswear and stretch fabrics, shows the strongest price resilience.

Practical Recommendations: Category-Specific Procurement Strategies

For Buyers - For PTA and polyester staple, maintain low inventory and fast turnover. Current prices are at high YoY levels; the single-day drop is insufficient to confirm a trend reversal. Observe whether key support levels (PTA 5,800 CNY/ton, polyester staple 7,200 CNY/ton) are breached in the next two weeks before restocking. - Increase order volume for cotton yarn. With cotton prices falling and yarn prices stable, the bargaining window for yarn is narrowing. Lock in some long-term contracts before raw material prices fall further. - For spandex and acrylonitrile-related products (e.g., spandex core-spun yarn, acrylic blends), procure on an as-needed basis and avoid stockpiling. High YoY gains mean cost risk remains, and downstream apparel brands have limited tolerance for expensive raw materials.

For Factories - Cotton mills should accelerate raw material procurement during the current price dip while maintaining flexible yarn pricing. If cotton prices continue to fall over the next month, consider offering "price guarantee" orders to attract customers. - Chemical fiber mills should monitor the basis between PTA and polyester staple futures and spot prices. If the basis strengthens, spot supply is tight and price hikes are possible; if it weakens, accelerate destocking. - For raw silk and silk quilt products, increase promotional efforts. A 10% YoY decline indicates strong buyer hesitation; proactive discounting or bundling can speed up cash flow.
