Last week (August 4-10, 2025), the market trend of upstream nylon PA6 chips for nylon filament gradually stabilized, with limited cost support and high inventory levels in the market. The supply side performed well, but the demand side did not improve. Downstream manufacturers’ purchasing enthusiasm was difficult to increase, and the market trading atmosphere was average. The price trend of nylon fiber market was weak and stable.
According to the Commodity Market Analysis System of Shengyi Society, the price of nylon filament remained weak and stable last week (August 4-10, 2025). As of August 10, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14320 yuan/ton; Nylon POY (premium product; 86D/24F) quoted 12050 yuan/ton; The price of nylon FDY (premium: 40D/12F) is quoted at 14900 yuan/ton, which is the same as the previous period.
Weak and stable support on the raw material side
In terms of cost: Last week (August 4-10, 2025), the spot market price of caprolactam remained weak and stable. The weekly settlement price of caprolactam by Sinopec was 9050 yuan/ton (interest free for six-month acceptance). The market price of nylon PA6 slices was weak and stagnant, with weak cost support. As of August 10, 2025, the benchmark price of caprolactam in Shengyi Society is 9070 yuan/ton, mainly due to weak price consolidation. During the week, the market price of high-speed spun nylon PA6 chips remained weak, stable, and fluctuating, with weak cost support being the main factor.
Supply and demand: During the week, some nylon filament manufacturers have lowered their operating rates, resulting in a decline in overall market supply. However, industry inventory levels continue to increase, leading to poor performance on the supply side; The demand in the end market is weak, and some downstream manufacturers have reduced production or switched production, resulting in a decrease in demand for nylon filament. It is difficult to find favorable support from the demand side, and many parties are following suit with rigid demand. Many industry players are adopting a cautious and wait-and-see attitude.
Future forecast
Cost aspect: In terms of caprolactam, the expectation for pure benzene is weak, and slice manufacturers have low enthusiasm for purchasing caprolactam. It is expected that the caprolactam market will be dominated by weak and low-level consolidation next week; In terms of PA6 slicing, cost support is limited, and the supply level of PA6 slicing market may continue to improve. Downstream market demand is weak, and it is expected that the market price of nylon PA6 slicing will weakly decline.
Supply and demand: August belongs to the off-season of traditional demand in the market, coupled with the lack of signs of improvement in terminal market demand and low purchasing enthusiasm in downstream markets. Therefore, it is expected that the demand for nylon filament market may decrease next month. If there is no significant improvement in demand, under the pressure of large inventory, some nylon filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of nylon filament market will decrease next month.
Overall, both the upstream raw material caprolactam spot market and the nylon PA6 chip market are likely to continue to decline, with a lack of cost support and difficulty in improving downstream market demand. The demand side is dragging down market trends, and under the dual negative factors, analysts from Shengyi Society predict that the short-term nylon filament market price will mainly consolidate weakly.
