On September 25, the number of textile commodities posting gains was zero, and the number posting losses was also zero. The daily change settled at 0%. But stretch the timeline to a year-on-year comparison, and the picture shifts dramatically: PTA leads with a 54.21% increase, while acrylonitrile, nylon POY, and polyester FDY register gains of 36.10%, 38.88%, and 35.80% respectively. Raw silk, by contrast, has fallen 6.17%. Within this single snapshot, a structural divergence in textile raw materials is unmistakable.
The Standoff Behind Flat Prices
A day of uniformly flat prices typically signals a market lacking directional drivers. What makes this particular flatline noteworthy is that it occurs against a backdrop of substantial year-on-year increases in synthetic fiber inputs. PTA spot prices hold at 7,147.50 yuan per ton, polyester staple fiber at 8,596.75 yuan, and viscose staple fiber at 14,580 yuan. These figures are not shocking in isolation. What is striking is that they sit 30% or more above where they were a year ago.
This price stickiness suggests that upstream cost support remains firm. The transmission chain from crude oil to PX to PTA has not loosened, yet downstream weaving orders appear hesitant. Buyers and sellers have reached a fragile equilibrium: sellers are unwilling to cut prices, and buyers are reluctant to chase highs. The flatline is not calm—it is the midpoint of a tug-of-war.
For industrial clusters, this stalemate places a premium on cash flow management. Mills in Keqiao and Shengze, hubs for synthetic fabrics, face direct margin compression if their earlier price-locking ratios were low, given that raw material costs have risen by a third year-on-year. The Nantong home textile cluster, which relies primarily on cotton and rayon yarns, faces comparatively manageable pressure—cotton yarn 21S and 32S are up 5.89% and 5.31% year-on-year—but end-product pricing power remains limited.
What Synthetic Versus Natural Fiber Divergence Means
Breaking down the year-on-year data, the synthetic segment is almost universally higher: polyester POY up 34.96%, polyester DTY up 31.46%, nylon DTY up 29.83%, spandex up 19.59%. Natural fibers present a mixed picture—cotton lint is up 15.18%, while raw silk has declined 6.17%. This is no accident.
The high year-on-year readings in synthetics stem from a low base in the prior year combined with systematic increases in energy and chemical feedstock costs this year. The weakness in raw silk reflects soft export orders for silk end-products. China Customs data corroborates this: export growth for silk fabrics to European and American markets has consistently trailed that of synthetic fabrics over recent quarters.
For buyers, this means bargaining room is diverging by category. Suppliers of synthetic raw materials have little incentive to concede on price, while sellers of silk materials may be more willing to offer concessions on payment terms or volume discounts. Procurement strategy cannot be one-size-fits-all; it must be category-specific.
Transmission Logic for Mills and Exporters
The core problem for mills is straightforward: raw material costs are up year-on-year, but retail prices for finished apparel and home textiles have not kept pace. National Bureau of Statistics data shows that the CPI for clothing has consistently lagged the PPI for textile ex-factory prices. This scissors gap is the quantitative evidence of margin compression.
The export side is more complex. RMB exchange rate volatility, elevated ocean freight rates, and tariff policy adjustments in certain markets are all eroding export margins. For synthetic fabric exporters invoicing in US dollars while sourcing raw materials in RMB at costs up 30% year-on-year, the actual margin contraction may exceed what the books show.
Notably, nylon products are up between 26% and 39% year-on-year, and nylon's primary downstream is sportswear and outdoor gear. Brands in this segment typically wield stronger pricing power and can pass some costs to consumers. By contrast, polyester staple fiber and polyester yarn serve a more fragmented downstream of small and medium-sized mills with weaker cost pass-through capability.
