SunSirs: Last Week, the Polyester Filament Market Showed a Weak and Stable Trend with Some Minor Adjustments in Certain Areas

Price trend:

Last week (January 5-9, 2026), the polyester filament market showed weak stability and a stalemate, with only minor adjustments in some areas. Mainstream prices remained unchanged, but actual transactions involved price concessions. Production and sales were sluggish, and inventories accumulated. The market was primarily influenced by the interplay of cost, supply, and demand. As of January 9th, the mainstream polyester filament 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 6,600-6,900 RMB/ton.

Key influencing factors

Cost side: PTA/ethylene glycol prices fluctuated upwards, increasing polymerization costs by 150-180 RMB/ton compared to the previous period. Factories maintained their prices, but processing margins were compressed, resulting in a weekly decrease in gross profit of approximately 120-150 RMB/ton. The increased losses were forcing expectations of production cuts.

Supply side: Operating rate was 78% (down 0.5% month-on-month), and maintenance shutdowns had increased (maintenance capacity of 4.5 million tons in January), but overall supply remained relatively ample; large manufacturers were reducing discounts, while smaller manufacturers were offering price concessions to move inventory, resulting in inventory levels of 18-22 days (up 1-2 days month-on-month).

Demand side: Operating rates at weaving/texturizing factories declined (to approximately 65%), and pre-Chinese New Year stockpiling was nearing completion. Purchases were mainly for immediate needs and replenishment, with weak willingness to chase rising prices and significant resistance to high prices.

Variety differentiation

FDY: Supply of bright 75D/36F was increasing, priced at 7,150-7,250; semi-dull 50D/24F was priced at 7,450-7,550, with sporadic demand from warp knitting.

DTY: 150D/288F was used for short pile fabrics, with stable prices supported by steady demand; 150D/144F was in oversupply, with prices as low as 7,700.

POY: 150D/144F transactions were concentrated in the 6,550-6,580 range, with downstream buyers mainly placing small orders for replenishment.

Overall, SunSirs believes that next week (January 10-16, 2026), polyester filament yarn prices will mainly remain weak and stable, with narrow fluctuations, and mainstream spot prices will fluctuate within ±50 RMB/ton;
