Analysis review

In August 2025, the polyamide filament industry continued to show signs of weakness. The price of raw material caprolactam weakened and declined during the month, providing limited support on the cost side, which had a negative impact on polyamide filament costs. Furthermore, the market was well supplied, and downstream demand remained weak, resulting in a sluggish trading atmosphere and slow textile terminal business. Overall, these negative factors persisted, leading to a cautious wait-and-see attitude among industry players. Manufacturers actively supported prices, resulting in a weak and stable polyamide filament market with prices remaining low.

Costs: In August 2025, caprolactam spot market prices remained weak, with Sinopec's August settlement price for high-end caprolactam at 9,330 RMB/ton. As of August 29, 2025, the SunSirs caprolactam benchmark price was 8,953 RMB/ton, a weak decline of 1.29% month-over-month. The market for polyamide PA6 chips and high-speed spinning chips came under downward pressure, with prices falling month-over-month, down 1.59%, indicating weak cost support.

Supply and Demand: In August, overall polyamide filament supply remained relatively stable, but trading activity remained sluggish, leading to continued inventory pressure on polyamide mills. Downstream orders remained low, leading to high inventories of grey fabrics. Coupled with low profits, slow cash flow, and tight funding, weaving companies were reluctant to resume operations, limiting production to just basic needs. polyamide mills were struggling to ship goods, making it difficult to find support from the demand side.

Market Forecast

Cost side: As for caprolactam, benzene is expected to be weaker, and chip manufacturers are not very enthusiastic about purchasing caprolactam. It is expected that the caprolactam market will be mainly weak and consolidated at low levels in the short term; as for polyamide PA6 chips, the cost side has limited support, the supply level of PA6 chips market may continue to increase, and the downstream market demand is weak. It is expected that the market price of polyamide PA6 chips will fall weakly.

Supply and Demand: September is a month of traditional market demand and a positive trading atmosphere, leading to an expected increase in polyamide filament market demand next month. However, due to inventory pressures, some polyamide filament manufacturers may reduce their production capacity. Furthermore, with the continued release of new production capacity, overall supply pressure remains high.

On the whole, the spot market of upstream raw material caprolactam and polyamide PA6 chips will continue to operate in a weak position, with a lack of support on the cost side and high supply pressure. It is difficult for the downstream market demand to improve significantly, and there are insufficient positive factors. Analysts from SunSirs predict that the polyamide filament market will continue to be weak and stable in the short term, with prices mainly consolidating weakly.
