The polyester chain and the cotton yarn chain moved in opposite directions within the same week, a split far more dramatic than the headline average of -0.11% suggests. PTA rose 1.39% week-on-week, while cotton yarn 21S and 32S fell 1.27% and 1.20% respectively, and polyester FDY dropped 1.57%. The signal is clear: costs are pushing up while demand is dragging down, squeezing margins in the midstream spinning segment.
Cost and Order Misalignment Behind the Moves
PTA climbed from 7,049.30 yuan/mt to 7,147.50 yuan/mt, a year-on-year gain of 54.21%. This is not isolated. Polyester POY and DTY edged up alongside it, with year-on-year increases of 34.96% and 31.46%, indicating that the polyester chain has both cost support and some restocking demand. But gains narrowed to around 0.4%, meaning momentum is fading and resistance to high-priced feedstock is building.
The cotton yarn decline follows a different logic. Cotton yarn 21S and 32S are up only 5.89% and 5.31% year-on-year, far below polyester products, suggesting weak pricing power in cotton spinning over the past year. Cotton lint was nearly flat this week, down 0.02%, but up 15.18% year-on-year. Feedstock has not loosened materially, yet yarn prices are probing lower, reflecting insufficient orders at weaving mills and passive inventory accumulation.
Raw silk held steady at 435,600 yuan/mt but fell 6.17% year-on-year, the only item with a notable annual decline. This contrast suggests demand recovery for high-end natural fibers is slower than for synthetics, and silk terminal exports remain under pressure.
Transmission Differences Across Industrial Belts
From an industrial belt perspective, this divergence affects chemical fiber weaving hubs like Keqiao and Shengze very differently from cotton spinning clusters in Nantong and Shandong. Mills in Shengze and Keqiao use polyester filament and POY as feedstock; rising PTA and POY directly raise their procurement costs. If fabric quotes cannot rise in tandem, processing margins will be compressed.
For cotton spinning clusters, falling yarn prices benefit downstream weavers and home textile firms looking to lock in cheaper cotton yarn, but they also increase destocking pressure on spinners. If spinners are forced to cut prices to move goods, a regional sell-off could follow, dragging down cotton lint buying interest and creating a negative feedback loop.
The nylon series was flat this week, but year-on-year gains range from 26% to 39%, indicating the nylon chain's price center remains elevated. For buyers of sportswear and outdoor apparel fabrics, the high annual base means cost pressure has not eased; the market is simply in a short-term holding pattern.
Practical Implications for Procurement and Export
The core contradiction is not absolute price levels but directional divergence between product categories. Polyester is high year-on-year but slowing weekly; cotton yarn is moderate annually but weakening weekly. Procurement strategies for these two lines should be formulated separately.
For mills using polyester as the main feedstock, the cost-effectiveness of chasing restocking is declining. Locking in prices through small,分批 orders and watching whether PTA holds above 7,100 yuan is more prudent than bulk buying. For weavers and home textile firms using cotton yarn, the current price pullback offers a window, but quote chaos from further spinner discounts is a risk. Short orders and quick replenishment are advisable.
Exporters need to watch how divergent year-on-year gains affect quote competitiveness. Polyester products are up over 30% annually; if quoted in USD, overseas buyers will resist price hikes far more than for cotton goods. This means cotton orders offer more bargaining room, while chemical fiber orders depend more on delivery times and added value.
