Last week (December 1-7, 2025), raw material prices rose, leading to a cautious upward shift in the polyamide filament market. The upstream caprolactam spot market and the polyamide PA6 chip market continued to maintain firm prices. Sinopec's caprolactam settlement price for the previous week was 9,100 RMB/ton (six-month acceptance without interest), providing strong cost support. This led 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 both positive and negative factors at play, the market showed a stronger upstream and weaker downstream trend, resulting in a cautious upward shift in the polyamide filament market and a slight price increase.
Price trend:
According to the business data analysis system of SunSirs, last week (December 1-7, 2025), the price of polyamide filament showed a slight upward trend, but the price remained at a low level. As of December 7, 2025, the price of polyamide filament DTY (premium grade; 70D/24F) in Jiangsu province was 13,720 RMB/ton, an increase of 160 RMB/ton from the previous period, with a weekly increase of 1.18%; the price of polyamide POY (premium grade; 86D/24F) was 11,400 RMB/ton, an increase of 100 RMB/ton from the previous period, with a weekly increase of 0.88%; and the price of polyamide FDY (premium grade: 40D/12F) was 14,225 RMB/ton, an increase of 50 RMB/ton from the previous period, with a weekly increase of 0.35%.
Cost side: Since mid-to-late November 2025, due to production cuts by caprolactam manufacturers, spot market prices have risen sharply. Last week (December 1-7, 2025), the caprolactam spot market continued to rise; the polyamide PA6 chip market mainly operated strongly, with prices increasing and strong support from the cost side. As of December 7, 2025, the SunSirs' benchmark price for caprolactam was 9,300 RMB/ton, an increase of 2.57% week-on-week; the price of high-speed spinning polyamide PA6 chips also increased during the week, with a weekly increase of 3.39%, providing positive support for polyamide yarn prices.
Supply and Demand: Last week (December 1-7, 2025), some polyamide filament manufacturers had ample overall 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 remain strong and consolidate 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 situation remains relatively loose, with no clear signs of improvement in the supply-demand structure. 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. In terms of costs, the caprolactam market is experiencing upward fluctuations, and the impact of potential production cuts by factories should be monitored, as this could boost polyamide filament prices. Overall, analysts at SunSirs predict that the polyamide filament market will maintain a stronger trend in the short term, with prices increasing slightly in line with raw material costs.
