SunSirs: Last Week, the Polyester Filament Market Showed Initial Stability, Followed by a Price Increase, and Then a Period of Stagnation

Last week (January 12-16, 2026), polyester filament yarn prices showed an initial stability followed by an increase, then a stalemate. Mainstream specifications of POY/FDY/DTY rose by 50-100 RMB/ton during the week. On Friday, prices stabilized due to a correction in raw material prices, with actual transactions subject to negotiation. The core drivers were a combination of cost support, supply contraction, and weak demand. According to SunSirs' commodity market analysis system, as of January 16th, mainstream polyester filament yarn factories in Jiangsu and Zhejiang quoted POY (150D/48F) at 6,500-6,800 RMB/ton, DTY (150D/48F low elasticity) at 7,700-8,000 RMB/ton, and FDY (150D/96F) at 6,700-7,000 RMB/ton.
