Last week (November 17-23, 2025), Sinopec's caprolactam, an upstream raw material for polyamide filament, saw an increase in its settlement price. The November 2025 settlement price was 8,900 RMB/ton (liquid premium grade, six-month acceptance, self-pickup), an increase of 320 RMB/ton compared to the October settlement price. The polyamide PA6 chip market saw an upward trend, supported by strong costs. Overall inventory levels were high, and downstream companies showed weak purchasing activity. With insufficient support from both the supply and demand sides, the polyamide filament market remained range-bound with prices remaining weak and stable.

Price trend:

According to data from the SunSirs' commodity market analysis system, polyamide filament prices remained weak and stable last week (November 17-23, 2025). As of November 16, 2025, the price of polyamide filament DTY (superior grade; 70D/24F) in Jiangsu Province was 13,560 RMB/ton; polyamide POY (superior grade; 86D/24F) was 11,300 RMB/ton; and polyamide FDY (superior grade: 40D/12F) was 14,175 RMB/ton, all unchanged from the same period last week, reaching a near five-year low.

Strong support from raw material supply

On the cost side: Last week (November 17-23, 2025), the spot market price of caprolactam rose, and the polyamide PA6 chip market remained strong, with prices rising slightly, but strong cost support prevailed. As of November 23, 2025, the benchmark price of caprolactam from SunSirs was 8,643 RMB/ton, an increase of 2.33% week-on-week. The price of polyamide PA6 chips in the high-speed spinning market also rose week-on-week, increasing by 2.5%, which was beneficial to the price of polyamide filament.

Supply and Demand: While overall supply from some polyamide filament manufacturers was sufficient during the week, industry inventory levels continued to rise. Some companies experienced order backlogs, but overall activity was far below the levels of the same period last year. Overall, market demand was weak, leading to increasing inventory pressure for polyamide manufacturers. The supply side performed poorly; end-market demand was sluggish, with some downstream manufacturers reducing or switching production, reducing demand for polyamide filament. Demand-side support was scarce, with most manufacturers maintaining only immediate needs, and industry players adopting a cautious wait-and-see attitude.

Market Forecast:

The polyamide filament market is expected to remain weak in the near term. Prices will see a slight increase due to rising raw material costs, while the upstream and downstream of the industry chain will continue to engage in strategic competition. On the supply side, market supply remains stable, with a relatively loose supply structure and no clear signs of improvement in the supply-demand structure. On the demand side, total orders will remain stable, with new orders primarily for winter insulation, and weaving manufacturers maintaining a cautious purchasing attitude. On the cost side, the caprolactam market fundamentals are undergoing a fluctuating upward adjustment; attention should be paid to subsequent factory production cuts. Signals of production reductions and reduced operating rates may boost prices, but prices are expected to remain low in the short term. Overall, analysts at SunSirs predict that the polyamide filament market will continue its weak trend in the short term, with prices rising slightly in line with raw material costs.
