As of July 30, 2025, the price of polyamide filament DTY (superior grade; 70D/24F) in Jiangsu Province was 14,320 RMB/ton, down 540 RMB/ton from the previous month, a monthly decrease of 3.63%. The price of polyamide POY (superior grade; 86D/24F) was 12,050 RMB/ton, down 475 RMB/ton from the previous month, a monthly increase of 3.79%. The price of polyamide FDY (superior grade: 40D/12F) was 14,900 RMB/ton, down 550 RMB/ton from the previous month, a monthly increase of 3.56%.

Analysis review

Looking back at July 2025, the polyamide filament industry exhibited a weak performance, with the monthly average price continuing to decline. The weak and low price of raw material caprolactam during the month had a negative impact on polyamide filament costs. Furthermore, while market supply was ample, downstream demand remained weak, resulting in a sluggish trading atmosphere and slow textile terminal business. Overall, negative factors dominated the market, driving the monthly average price downward.

Costs: In July 2025, caprolactam spot market prices remained weak. Sinopec's high-end caprolactam settled at 9,060 RMB/ton in July, down 660 RMB/ton from the June settlement price. As of July 30, 2025, the SunSirs’ caprolactam benchmark price was 9,020 RMB/ton, a weak decline of 3.77% month-over-month. The market for polyamide PA6 chips and high-speed spinning chips came under downward pressure, with prices falling month-over-month. The price of polyamide PA6 fell 1.26%, indicating weak cost support.

Supply and Demand: In July, 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.

Future outlook:

Driven by the "anti-involution" sentiment in the benzene market in August, prices may see a slight rebound, which will slightly boost the cost side of the raw material caprolactam, and caprolactam prices may rise slightly. Influenced by this, the cost side of polyamide PA6 will form a favorable support, and the quotations of polymerization factories may rise slightly. Downstream buyers are buying high and not buying low, and the trading atmosphere improves. However, terminal demand is still weak, which may curb the price increase of polyamide PA6. Terminal demand for polyamide filament is unlikely to improve. The polyamide filament production in August may be lower than that in July. Overall, the supply chain is still ample. On the demand side, downstream weaving companies are in the off-season for domestic sales orders. Overall, the cost side is expected to be stronger, supply pressure is relatively high, and downstream weaving companies are maintaining production for just-in-time needs. Demand is still weak, and there is insufficient positive news. Analysts of SunSirs predict that polyamide filament may operate weakly under pressure next month, with limited price fluctuations.
