The commodity price monitoring data on August 28, 2026, reveals a telling signal: among 16 major textile raw materials tracked, only three posted a week-on-week increase, while the rest held flat. This pattern of 'few rises, many pauses' does not indicate a sluggish market but rather a typical phase of tug-of-war between upstream and downstream segments. Raw silk jumped 2.67% in a single day, with PTA and cotton following at 0.59% and 0.51%, respectively, pushing the sector's average daily gain to 0.22%. However, the year-on-year data hides a more significant structural divergence.
The Logic Behind Price Divergence
Raw silk soared from 416,400 yuan per ton to 427,500 yuan per ton, a record daily gain, yet it still fell 9.16% year-on-year. This pattern of 'short-term spike, long-term pressure' suggests the current rise is driven by temporary supply-demand mismatches rather than a trend reversal. Seasonal tightening of cocoon supply, compounded by hot weather affecting cocoon quality in some major producing areas, has tightened spot availability. However, downstream silk fabric orders have not seen a synchronized increase, leaving the sustainability of price transmission dependent on the recovery of end-consumer apparel demand.
PTA and cotton posted modest gains, clearly cost-push in nature. PTA rose 26.54% year-on-year, and cotton climbed 19.12%, both far exceeding their daily increases. PTA's rise is directly linked to higher crude oil price benchmarks, while cotton is supported by global production cut expectations and rising planting costs. Notably, cotton yarn 21S and 32S prices remained flat, with year-on-year gains of only 5.89% and 5.63%, far below cotton's increase. This indicates that profit margins in the spinning segment are being squeezed by raw material costs, and some small- and medium-sized mills may be hovering near breakeven.
Stagnation and Concerns in the Chemical Fiber Chain
Polyester, nylon, and viscose all held flat on the day, but their year-on-year gains ranged from 10% to 25%. Acrylonitrile led the sector with a 44.12% year-on-year increase; polyester POY, FDY, and DTY rose 24.25%, 21.81%, and 21.66%, respectively; and spandex climbed 21.65%. These figures indicate that the chemical fiber chain has experienced significant cost-push inflation over the past year, yet the recent price plateau reflects insufficient willingness among downstream weavers and garment makers to absorb further increases.
Polyester staple fiber was quoted at 7,744.82 yuan per ton, up 17.93% year-on-year, but polyester yarn rose only 5.90%, widening the spread to over 4,000 yuan per ton. This 'raw material up, yarn not up' scissors effect directly compresses spinning margins. For factories primarily producing polyester yarn, raw material procurement requires extra caution to avoid locking in excessive inventory at high prices. Meanwhile, nylon DTY and FDY posted year-on-year gains of 16.90% and 14.09%, relatively moderate, suggesting less acute supply-demand tension in the nylon chain compared to polyester.
Impact on Procurement and Production
Price flatness does not mean market calm. For buyers, the fact that only three products rose suggests limited room for price negotiation, especially for raw silk, PTA, and cotton, where suppliers may push for increases. The sharp fluctuation in raw silk prices poses a direct challenge to cost control for silk fabric manufacturers—if downstream orders cannot be repriced accordingly, margins will be eroded. Conversely, stable chemical fiber prices offer a relatively predictable cost environment for buyers focused on polyester and nylon.
From an industrial cluster perspective, weaving hubs like Shengze and Keqiao are more sensitive to chemical fiber price movements. The current sideways movement in polyester filament prices helps stabilize grey fabric quotes, but vigilance is needed regarding lagged transmission from crude oil volatility. The Nantong home textile sector is more influenced by cotton and cotton yarn prices; the sluggish yarn price response may prompt some companies to increase blends or chemical fiber substitution. Overall, the textile chain is in a 'strong upstream, weak midstream, and yet-to-be-verified downstream' pattern, with order visibility at the end of Q3 becoming the key variable for price direction.
