Last week (December 8-14, 2025), the price of caprolactam, a raw material, continued to rise, and the focus of the polyamide filament market continued to increase slightly. The upstream raw material caprolactam spot market and the polyamide PA6 chip market maintained firm prices. Sinopec's caprolactam settlement price for the previous week was 9,885 RMB/ton (six-month acceptance with interest-free payment), providing strong cost support and leading to a reduction in low-priced polyamide filament sources. However, overall inventory levels in the market remained high, and downstream market purchasing activity was generally weak, with buyers only purchasing as needed.  Under the interplay of positive and negative factors, with upstream strength and downstream weakness, the focus of the polyamide filament market cautiously moved upward, and prices continued to rise slightly.

Price trend:

According to SunSirs' commodity price analysis system, last week (December 8-14, 2025), polyamide filament prices continued to rise slightly, but prices remained at a low level. As of December 14, 2025, the price of polyamide filament DTY (premium grade; 70D/24F) in Jiangsu province was 13,760 RMB/ton, an increase of 40 RMB/ton from the previous period, a weekly increase of 0.29%; the price of polyamide POY (premium grade; 86D/24F) was 11,500 RMB/ton, an increase of 100 RMB/ton from the previous period, a weekly increase of 0.88%; and the price of polyamide FDY (premium grade: 40D/12F) was 14,275 RMB/ton, an increase of 50 RMB/ton from the previous period, a weekly increase of 0.35%.

Market Analysis

Regarding costs: Since mid-to-late November 2025, due to production cuts by caprolactam manufacturers, spot market prices rose sharply. It is understood that Cangzhou Xuyang's 150,000-ton plant was shut down, as had a 150,000-ton plant at a major manufacturer in Shandong; Nanjing Dongfang's 200,000-ton plant had also been shut down; Zhejiang Baling Hengyi had reduced production on one 100,000-ton line; and other factories had implemented varying degrees of production cuts. The estimated total impact on production capacity exceeded 1 million tons, leading to a reduction in caprolactam supply and thus driving up prices.

Last week (December 8-14, 2025), the spot market for caprolactam continued to rise; the polyamide PA6 chip market mainly operated on a strong trend, with prices increasing and strong support from the cost side. As of December 14, 2025, SunSirs' benchmark price for caprolactam was 9,562 RMB/ton, an increase of 2.81% compared to the previous week, providing positive support for polyamide yarn prices.

Supply and Demand: Last week (December 8-14, 2025), some polyamide filament manufacturers had ample supply, and industry inventory levels continued to increase. While some companies experienced order backlogs, overall activity was far below the level of the same period last year.  Overall, market demand was weak, leading to increasing inventory pressure on polyamide manufacturers. Supply-side performance was poor; weak demand in the end market, coupled with production cuts or shifts to other products by some downstream manufacturers, reduced demand for polyamide filament. There was little positive support on the demand side, with most buyers only purchasing for immediate needs, and industry participants generally maintained a cautious wait-and-see attitude.

Market Outlook

The polyamide filament market is expected to consolidate with an upward bias in the near future.  Due to rising raw material costs, prices are expected to increase slightly, and the upstream and downstream segments of the industry chain will continue to engage in price negotiations. In terms of supply, market supply remains stable, and the supply structure remains relatively loose, with no clear signals of improvement in the supply-demand balance. On the demand side, overall order volume remains stable, with new orders mainly driven by essential demand for winter thermal insulation products. Weaving manufacturers remain cautious in their purchasing. Regarding costs, the caprolactam market is experiencing upward adjustments, and the impact of potential production cuts by factories should be monitored, as this could boost polyamide filament prices. Overall, however, due to the high cost of raw materials, price increases may lag behind. Analysts at SunSirs predict that the polyamide filament market will maintain an upward trend in the short term, with prices increasing slightly due to rising raw material costs.
