The second week of July 2026 saw a rare two-tier market in textile raw materials. PTA surged 2.25% week-on-week, with a year-on-year gain of 21.8%, while acrylonitrile plummeted 4.2%, marking its steepest weekly drop in recent months. This divergence is reshaping profit distribution along the textile chain, from upstream petrochemicals to downstream weaving and garment manufacturing.
Raw Material Divergence: PTA Strength vs. Acrylonitrile Weakness
PTA's rally was underpinned by tight PX supply and high polyester operating rates. Industry data shows PTA prices rose from 5,780 yuan/ton to 5,910 yuan/ton. Polyester mills stocked up ahead of summer maintenance, while several PTA units went offline for repairs, tightening spot supply. For downstream polyester staple fiber and filament producers, this means rising input costs, but whether end-user demand can absorb these increases remains uncertain.
In contrast, acrylonitrile plunged from 9,533 yuan/ton to 9,133 yuan/ton. Weak demand from acrylic fiber and ABS resin sectors led to inventory buildup. Several plants restarted after maintenance, adding supply pressure. This decline benefits acrylic yarn and carbon fiber precursor producers, but squeezes margins for acrylonitrile manufacturers.
Polyester Filament vs. Cotton Yarn: Weakness and Resilience
Polyester filament yarns weakened across the board. FDY fell 1.68%, DTY dropped 1.28%, and POY declined 0.77%. This marks the third consecutive weekly decline, contrasting sharply with rising PTA prices. The spread between raw material and finished product suggests shrinking processing margins. Summer is traditionally a low season for weaving, with mill operating rates dropping to around 60%. Purchases are limited to immediate needs, with little speculative stocking.
Cotton yarn, however, showed resilience. 32S cotton yarn rose 0.61%, and 21S gained 0.28%, with year-on-year gains above 7%. Support came from two factors: high absolute cotton prices (despite a 0.92% weekly dip) and low mill inventories for certain specifications, giving sellers stronger bargaining power. Viscose staple fiber and rayon yarn prices were flat, indicating a stalemate in the regenerated cellulose fiber market.
Implications for Downstream Procurement and Inventory Management
The sharp price divergence demands more agile procurement strategies. The temporary gap between rising PTA and falling polyester filament creates a cost window for weavers. Locking in filament orders now could yield cost advantages before PTA hikes fully pass through. However, if PTA continues to climb, polyester filament prices are likely to follow in late Q3, raising procurement costs significantly.
Acrylonitrile's plunge offers a buying opportunity for acrylic yarn mills and wool-blend producers. With prices near psychological support levels, a phased buying approach is recommended, avoiding large bulk purchases that risk further downside.
For cotton yarn buyers, prices are in a high-range consolidation. Given lingering downside risk for raw cotton, maintaining lean inventories and covering only confirmed orders is prudent.
