Cotton yarn prices in the Hutang market have shown zero movement for a full week, and that signal deserves more attention than any rise or fall. According to China Customs data and publicly available industry figures, on September 13, benchmark cotton yarn prices from major producing regions including Anhui, Xinjiang, Henan and Shandong were completely flat week-on-week. OE7S was quoted at 15,800-15,900 yuan/ton, 21S at 21,300-22,100 yuan/ton, 32S at 23,900-24,000 yuan/ton, and J40S held at 26,800-27,000 yuan/ton. A flat market means buyers and sellers have reached a fragile equilibrium, but beneath that balance, the order gap on the weaving side is quietly building.
Divergence: Polyester Leads, Rayon Follows
In contrast to cotton yarn's calm, pure polyester and rayon yarns saw modest increases. Zhejiang-origin pure polyester 16S, 21S and 32S were quoted at 10,700, 11,100 and 12,200 yuan/ton respectively, each up 100 yuan/ton from the previous week. Rayon 20S and 30S also rose by 100 yuan/ton to 17,200 and 18,400 yuan/ton. Polyester-cotton T65/C35 series remained stable, with 21SK at 15,200 yuan/ton, 32SK at 15,500-15,700 yuan/ton, and 45SK at 16,800-16,900 yuan/ton.
This divergence is no accident. The polyester yarn increase directly tracks firmer PX and PTA prices, with cost pressure transmitting from chemical fiber plants to spinning mills, which have little choice but to pass it on as margins tighten. Rayon's rise is linked to tighter viscose staple fiber supply, and Zhejiang, as the main rayon yarn production base, reacts most sensitively to raw material swings.
Cost vs. Demand: Two Forces Pulling Apart
Why can't cotton yarn move up? The core issue is weak demand. Weaving mills have not significantly raised operating rates, downstream fabric orders are mostly short and small, and buyers show little appetite for restocking cotton yarn. Although spot cotton prices have not fallen sharply, spinning mills lack the ability to pass costs downstream when orders are thin.
For buyers, the flat cotton yarn market actually offers a window. The 100 yuan/ton increases in polyester and rayon yarns are small in absolute terms but signal firmer raw materials. If PX and PTA continue to climb, polyester yarn has room for further gains. Exporters should note that overseas customers are highly sensitive to quotes on polyester-containing products, and rising costs could squeeze margins in the middle of the supply chain.
Industrial Belt Reaction: Hutang as a Barometer
Hutang, a key yarn distribution hub in East China, often leads other industrial belts in price movements. The combination of flat cotton yarn and slight increases in polyester and rayon reflects a typical upstream cost push meeting weak midstream demand.
Regionally, Xinjiang cotton yarn quotes exceed those from Anhui and Henan in several specifications, reflecting differences in raw material quality and transport costs. Zhejiang dominates rayon and pure polyester yarn, underscoring the cluster advantage of its chemical fiber supply chain. For mills, this means cotton blending plans and raw material substitution strategies need to be more flexible.
Short-Term Outlook: Flat Market Hard to Break
Over the next one to two weeks, cotton yarn prices are likely to stay flat unless weaving orders rebound beyond expectations. Polyester and rayon trends will depend on PX, PTA and viscose staple fiber prices. If crude oil remains firm, pure polyester yarn may edge up further, but gains will be capped by downstream acceptance.
Buyers should not bet heavily on cotton yarn declines, as current prices are near some mills' cost lines. Exporters should watch exchange rates and ocean freight, and calculate the full cost of polyester-containing exports.
