The main staple fiber futures contract surged 1.70% to close at 7,402 points on the morning of July 15, driving bullish sentiment across the entire polyester chain. PTA rose 1.22% and bottle-grade chips gained 1.39%, forming a clear upward linkage. In contrast, cotton 2609 futures edged up only 0.22%, and cotton yarn 2609 managed just a 0.09% gain—less than one-tenth of staple fiber's advance. Within the same trading session and along the same industrial chain, upstream and downstream products delivered sharply divergent performances.
Cost and Inventory Drive Staple Fiber's Independent Rally
Staple fiber's rise was not without reason. Upstream PTA strengthened in tandem, closing at 5,800 points, up 1.22%. The rally was supported by two factors: narrowing naphtha cracking margins on the PX side, and concentrated maintenance at major PTA plants in early July, which pushed industry operating rates to around 76% and tightened spot supply. Staple fiber's own fundamentals also aligned—inventories were at multi-year lows for the season, with some major mills reporting queuing for shipments.
This structure of cost push plus low inventory created a clear premium within the polyester chain. Staple fiber outperformed PTA, bottle-grade chips landed in the middle, forming a typical 'cost transmission-inventory premium' chain. Notably, bottle-grade chips' 1.39% gain sat between staple fiber and PTA, reflecting relatively stable demand from beverage packaging, without unexpected upside surprises but also without dragging performance.
Cotton Textiles Lag, Downstream Orders Fail to Materialize
Cotton and cotton yarn gains were almost negligible. At 0.22% and 0.09%, these moves amount to technical follow-through in futures markets. Behind this lies the real predicament of the cotton textile chain: upstream spot cotton trade is sluggish, Xinjiang cotton outflows are declining month-on-month, and gray fabric mill operating rates slipped below 60% in early July, with some small and medium weaving mills starting early shutdowns.
Cotton yarn futures rose even less than cotton, implying compression of spinning margins. Current immediate profit for ring-spun C32S cotton yarn is near breakeven, prompting some mills to voluntarily cut output. This is not a situation that can be reversed by modest futures gains.
Regional Cluster Reactions: Shengze Polyester Sales Surge, Nantong Cotton Trade Stagnates
This product divergence is even more visible at the industrial cluster level. In polyester clusters like Shengze, Changxing, and Xiaoshan, polyester filament yarn sell-through rates on July 15 generally exceeded 120%, with some mills suspending quotations. Weaving mills showed strong restocking appetite, driven by the fear of further price increases—the consecutive rally in staple fiber and PTA has created bullish expectations, with downstream players worried about further cost escalation.
In contrast, in cotton hubs like Nantong, Lanxi, and Guangfo, market sentiment was starkly different. Cotton yarn traders widely reported 'more inquiries, fewer transactions,' as downstream garment and home textile makers continued digesting earlier inventories, with new orders flowing slowly. The Lanxi gray fabric market even saw price cuts failing to move goods, with some specifications falling below cost.
Root Cause: Mismatched End-Use Demand Recovery Pace
The divergence between the polyester and cotton chains stems from different recovery rhythms in end-use demand. Polyester staple fiber's downstream includes nonwovens, filling materials, and some home textiles—areas with relatively stable demand driven by summer heat and tourism. Cotton's downstream is mainly apparel and home textile finished goods, currently in the traditional off-season, with autumn/winter orders yet to launch in scale.
Another key variable is raw material import structure. Staple fiber and PTA's feedstock PX is mainly supplied by domestic integrated refining-petrochemical complexes, making it relatively less exposed to geopolitical risks. In contrast, cotton prices face three overlapping uncertainties: import quota policy, ICE cotton futures, and Xinjiang cotton consumption expectations.
Strategically, near-term polyester chain products may maintain a firm bias, but chasing rallies carries accumulating risk—end demand hasn't exploded; this is more a cost-push and inventory cycle resonance. Cotton products need to wait for tangible autumn/winter order pickup and are likely to remain range-bound at low levels.
