Cotton Yarn Leads, Polyester Filament Under Pressure: July 7 Textile Raw Material Price Divergence Reveals New Supply Chain Logic

The July 7 textile bulk commodity price board appears uneventful at first glance—only 7 of 17 monitored items changed, and the overall average rose a mere 0.07%. However, peeling back the cotton and chemical fiber threads reveals two very different industrial logics at play.

Cotton System: Cost Push and Order Resilience Cotton yarn 32S rose 0.61% to 24,875 yuan/ton, up 7.22% year-on-year; cotton yarn 21S edged up 0.28% to 23,466.67 yuan/ton; and raw cotton gained 0.19% to 17,904.83 yuan/ton. The synchronized uptrend indicates that upstream cotton costs are passing through to yarn. Year-on-year, raw cotton is 17.78% higher, while cotton yarn 32S is up 7.22%, showing that downstream weaving mills are still absorbing higher-priced cotton.

This pass-through is supported by end-order structures still favoring natural fibers. In the first half of 2026, European and American markets have increased procurement preferences for organic and recycled cotton products, and domestic home textile and apparel brands have accelerated cotton product stocking. The cotton textile chain's inventory cycle remains relatively healthy, with no major stockpiling at mills.

Chemical Fiber: Strong PTA, Weak Polyester Filament PTA rose 0.53% to 5,811.34 yuan/ton, up 16.75% year-on-year, one of the biggest gainers. But polyester filament showed divergence: FDY fell 0.40%, POY fell 0.15%, while staple fiber inched up just 0.06%. This "strong raw material, weak finished product" pattern means polyester mills' margins are being squeezed.

PTA's strength is supported by high crude oil prices and tight PX supply. But downstream weaving mills, facing high-priced polyester yarn, show little restocking appetite. The declines in FDY and POY reflect slowing demand growth for chemical fiber fabrics—especially in export markets, where Southeast Asian competitors are squeezing Chinese mills on conventional polyester products.

Warning Signals from High-Elasticity Items Spandex held flat at 29,666.67 yuan/ton, but its year-on-year gain of 21.09% was the highest among all items. Spandex's price volatility is as high as its physical elasticity. The sustained high price means downstream stretch-fabric mills have faced cost pressure for months; some small and medium mills may be forced to adjust product mixes, reducing spandex content or switching to alternative elastic fibers.

Raw silk fell 10.00% year-on-year to 426,000 yuan/ton, reflecting recovering cocoon output and weak silk end-consumption. For silk fabric exporters, lower raw material costs are a margin boon, but if overseas luxury brand orders shrink, this benefit will be offset by declining order volumes.

Practical Recommendations

For Procurement Teams - Cotton yarn remains in an uptrend; mills with immediate needs should lock in prices in batches covering 3-4 weeks of usage to avoid driving up prices through concentrated buying. - Polyester filament is under short-term pressure; consider delaying restocking and waiting for a PTA pullback before replenishing. - Spandex is at historical highs; negotiate quarterly floating-price contracts with suppliers to avoid locking in high prices.

For Exporters - Cotton fabric quotes can be raised moderately; European and American buyers have higher tolerance for organic cotton premiums—focus on high-count, high-density cotton products. - Polyester fabric exports face Southeast Asian price competition; shift to differentiated products such as recycled polyester or cationic dyeable polyester. - With raw silk prices low, silk exporters can reduce input costs, but must simultaneously assess end-order stability to avoid inventory buildup.
