Price trend:

Last week (December 8-12, 2025), the polyester filament market generally showed a weak downward trend in prices. Prices for all major types of polyester filament decreased compared to the previous week. As of December 12th, the mainstream polyester filament factories in Jiangsu and Zhejiang provinces quoted prices as follows: POY (150D/48F) at 6,200-6,500 RMB/ton, DTY (150D/48F low elasticity) at 7,700-8,000 RMB/ton, and FDY (150D/96F) at 6,600-6,850 RMB/ton. The price decreases varied for different product types, and the interplay of supply, demand, and cost factors dominated the market last week.

Regarding raw materials:

Insufficient and unstable cost support: Last week, MEG prices fell to their lowest level in recent years. Although PX and PTA had some bottom support, the overall polyester raw material market showed a weak downward trend, making it difficult to provide strong cost support for polyester filament. At the same time, while industry efforts to curb oversupply managed to prop up some prices, they were unable to offset the pressure from fluctuations in other cost components.

The supply-demand imbalance continued to worsen: On the supply side, domestic polyester filament yarn production capacity increased by over 3 million tons this year, with several more plants starting production in December, leading to a continuous increase in market supply. On the demand side, the off-season, coupled with unusually warm weather, had delayed the start of winter clothing demand.  Previous orders were completed, and the operating rate of chemical fiber weaving factories in Jiangsu and Zhejiang provinces had dropped from 69.5% to 65.5%. Downstream weaving and texturizing factories were mostly buying only what they need, with very little willingness to stockpile inventory. This supply-demand imbalance had led to a continuous accumulation of factory inventory.

Market outlook

According to SunSirs, production and sales data for the polyester filament industry were below expectations, and most polyester finished products were operating at a loss. Although companies occasionally boosted production and sales through discounts and price reductions, the core problem of shrinking end-user demand remained unresolved. Textile manufacturers may even consider taking early holidays, leading to a lack of confidence in the future market and a prevailing wait-and-see attitude.
